It cannot be said that the idea of ​​creating a heating system without batteries belongs to to modern man, but its effective implementation is still his merit. There are many advantages of water heated floors, but in each individual case the effectiveness of the used technical solution largely depends on a whole range of factors, including the correct execution of calculations, installation, and the use of the optimal set of materials and components.

Most of the disadvantages of water heated floors that are noted experienced users Such systems are largely formed from mistakes made initially, which led to a decrease in the efficiency of using the system. But in order to talk in detail about the pros and cons of warm water floors, available designs, constructive solutions, it’s worth understanding how they work.

Structurally, all types of water heated floors used today are a system of pipelines laid inside the floors. building structures. Coolant is pumped through them under the action of a pump, the temperature of which is up to 40 °C. As a result, the concrete screed is constantly heated, which in turn gives off its heat to the floor covering and the air.

Among the features of a water floor, it is worth noting that in this case it can be used as a source of energy as a system centralized water supply, and an individual heating source. As a result, a unique modification of the heating device is formed in the room, emitting heat and heating the room using air convection.

The characteristics of a water heated floor and its design make it possible to use not only water, but also non-freezing liquid as a coolant. The second option is optimal for use, for example, in dachas, where winter time the house may not be heated for a long time. In addition, it is important to take into account when designing and implementing such systems that all types of heated water floors can be used both as the main and additional sources of heating in combination with radiators.

The design of a heating system when using heated floor technology is never (even in its simplest design) limited to the working pipeline. In this case, each of the used components of the “pie” is important, from the supporting base to the finishing coating.

The technology for laying water mains can differ radically depending on its design. The basis can be either a concrete screed or dry structures (prefabricated screeds and frame structures are used with high efficiency). But it is worth noting that the second option is practically not used in practice, since it is distinguished by the complexity of its design at lower operational characteristics water heated floor.

The optimal thickness of the screed is determined based on the balance of the strength of the resulting structure and the heating rate of the slab. In this case, the recommended thickness is 5 cm. If there is a possibility of subsidence, a metal reinforcing mesh is used, but with the installation of rigid insulation, such a need disappears.

What determines the effectiveness of using different types of heated water floors?

In order to fully evaluate all the advantages and disadvantages of a warm water floor, it is necessary to take into account the influence of parameters on which the efficiency of use depends similar system generally. This is the only way to give an objective assessment of this method of heating a room.

In this regard, correct installation, correct execution of engineering calculations for heat and power losses are the most important condition for successful implementation heating system. But when determining power, an individual approach is no less important. When designing a warm water floor, the advantages of its design can be completely neutralized if factors such as local climatic conditions and the type of building are not taken into account (it can be either an apartment building or a private house with relatively cold and quickly cooling walls).

Concerning correct installation, then if you want to really appreciate all the advantages of a water heated floor, you should not take it up in the absence of sufficient experience and knowledge in this area. It's about not only about making an even screed, laying pipes without allowing leaks, and then laying finishing coat. It is extremely important to correctly select thermal insulation, the number of circuits, pitch, and screed parameters.

In addition, due to inexperience, one can appreciate one of the most important disadvantages of water heated floors: the ability of constant heating to ruin massive furniture. Although in fact the issue can be resolved quite simply: it is enough to lay the pipelines so that they do not pass through areas where large furniture is located. As a result, the floor temperature will not be high enough to have a noticeable effect on the furniture installed in the house. In addition, this approach will create an additional advantage of a water heated floor - the opportunity to save money.

Advantages and disadvantages of water heated floors

Advantages of a warm water floor

Disadvantages of water heated floors

• There is no way to effectively use the technology in rooms where a large area is occupied by stairs. You will need to use heated floors in combination with radiators.
• There is a common misconception that the advantage of water heated floors is that it slightly reduces the level of humidity in the room. In fact, such a system dries out the air much more than a traditional radiator system, so purchasing an air humidifier will become a necessity.
• The installation of a water system in apartment buildings is not allowed due to a significant increase in hydraulic resistance.
• Installation is quite complicated and can only be done during a major renovation of the premises.
• If you choose between water or infrared heated floors, it is important to consider that using the first option always leads to a significant increase in the floor level. For device infrared systems 100 micron thick polyester film is used.
• There is a possibility of a leak that will require quite complex repairs.

Which heating is better: warm water floor or radiators

In most cases, the choice of heating system is between water heated floors or radiators. In order to decide, it is enough to compare both options according to several key characteristics, which will allow you to evaluate all the possibilities, pros and cons of the technologies.

Economical

This is one of the most important issues, which in the future will determine the amount of annual/monthly heating costs. If we compare both options for the distribution of hot air flows in the room, it turns out that greatest heat the battery remains next to it. Heating from the heated floor occurs throughout the entire area of ​​the room.

Batteries are always installed under a window to avoid intense condensation. But this same decision causes intense heat loss to occur in the same zone. In addition, if the walls are insufficiently insulated due to the high temperature difference, the situation is aggravated.

Also, the efficiency of using a heated floor is increased due to the fact that during its operation the concrete slab is heated, which becomes a powerful source of heat, and the radiator can only act on the nearby air. As a result, savings when using heated floors average up to 30%.

Which is cheaper: water heated floors or radiators?

In this case, much depends on the area of ​​the premises and the installed equipment. But due to the large amount of work involved in installing concrete screeds, hidden gasket pipelines, the need to attract specialized specialists to perform such tasks, the cost of equipment and its installation when using a radiator system will be lower.

Inertia

The rate at which the room heats up when the heating is turned on is an important issue that largely determines the degree of comfort in using the system. In this case, deciding whether a warm water floor or radiators is better will not be easy. The peculiarity of the first option is that, for objective reasons, it will take longer to heat up a concrete slab than a radiator exposed to air. But at the same time, cooling when the heating is turned off using a heated floor will occur much more slowly. In this regard, the decision about whether this is a plus or a minus of water heated floors can only be made by the user himself.

Maintainability

The main problem in this case is the issue of accessibility. installed equipment, pipelines. For water heated floors, this is a minus, but at the same time, provided that the equipment is properly selected and the system is correctly designed and installed, the service life of hidden heating without the need for repairs will be equal to the service life of the pipes. That is, on average, you won’t have to open the screed for about 50 years. Equipment based on radiators is always open to access, but at the same time it requires repairs much more often.

There are quite a lot of arguments in favor of each option, but at the same time optimal solution in most cases it becomes the use of a combined system using both technologies. At the same time, all the pros and cons of warm water floors and radiators will be taken into account and used so that in the end the project will only benefit from their joint use.

Modern trends in interior fashion inspire property owners to use smooth and cool coverings as flooring materials - laminate, tile, travertine or parquet. Despite the aesthetic appearance and high wear resistance, these materials do not perform at their best in the cold season - they are cool to the touch, so walking on such a floor without slippers is uncomfortable.

To solve this problem, experts in the field of heating engineering recommend paying attention to water heated floors, which will appeal to consumers who crave comfort and warmth.

Hydronic underfloor heating is an effective way to heat a residential home, commercial building or office, where heat production is concentrated in the lower part of the room. The main advantage of this technology is its versatility. The design of a warm water floor can be used in any room - bathroom, living room, bedroom or kitchen.

Among other advantages of the technology, the following factors are worth mentioning:

The main disadvantages of this type of home heating are related to the labor intensity of the work and the high cost of consumables necessary to implement the heating scheme. Despite the fact that the technology has some disadvantages, in general it justifies itself and is the best choice for homeowners who want to get reliable source comfortable heat, the operation of which is not associated with high monthly costs.

How does this technology work?

To assess the feasibility of installing a structure, it is not enough to simply study the pros and cons of a water heated floor, since a complete analysis requires in-depth knowledge affecting the operating principle of the technology. through the use of the network special pipes small cross-section, which are built into the floor and then filled with concrete or dry screed.

The basic circuit diagram involves the use of the following elements:

In the process of heating the coolant using a boiler, solar collector or electric heater the floors are heated and contribute to the creation comfortable temperatures ny conditions in the room. Compared with conventional systems heating systems that involve the use of radiators, fireplaces or convectors, heated floor technology is the most justified - it concentrates heat below, warms the feet, and makes the climate in the house comfortable and healthy.

An important point is that direct supply of coolant is only possible from, which heats the water to an acceptable 40-45 degrees. When using boilers of another type, the owner will need to equip a mixing unit involved in lowering the temperature of the coolant.

Behind last decades technologies for creating heated water floor systems have stepped far forward and today owners who connect a heated water floor are fully insured against problems such as leaks, water hammer, pipe damage from corrosion, etc. However, in order for the heated floor to meet all expectations, its installation must be carried out by responsible specialists in accordance with the recommendations of the heating scheme developed by heating engineers.

Is the high cost of water heated floors justified?

Hydronic underfloor heating systems cost much more than traditional types of heating. average price per m2 of water heated flooring is about $30, taking into account the work and the purchase of components, so the cost of a project for a house with an area of ​​one hundred square meters can be quite high. At the same time, low operating costs in the long term justify the investment of property owners.

The average temperature of a water heated floor is 40-45 degrees. Therefore, during operation, such a system requires much less energy resources than a traditional radiator circuit. In addition, you need to know that the average cost of 1 m2 of water heated floor is calculated taking into account the purchase of all necessary components of the system, including:

How larger area home, the lower the cost per square meter of heated floor, since the cost of the most expensive element of the system - the boiler - is evenly distributed over each square of area.

Review of popular manufacturers

The final cost of 1 square meter of warm water floors also depends on the choice of components produced by different brands. At the moment, on the domestic market you can purchase a Rehau warm water floor, produced in Germany. The German brand guarantees high quality products and excellent consumer characteristics of the system. The affordable price of a Rehau water-heated floor allows you to save money already at the first stage of a home heating project.

Among other advantages that a Rehau warm water floor has, it is worth highlighting the following qualities:

Manufacturers from other countries also operate on the market, these are:

The choice of manufacturers is quite large and the consumer may not be limited to foreign brands, because in addition to those listed, their products are more expensive affordable prices They are sold on the market by companies from the Russian Federation and neighboring countries.

How does electric-water heated floor work?

An electric water heated floor, which is a combined heating system, can be installed in the house. This system uses special antifreeze as a coolant, and the design itself consists of pipes with a small internal cross-section (about 24 mm), inside of which a cable is placed. Liquid electric floors are different simple installation and low installation costs.

The most popular products on the market are products from the XL Pipe brand. Positive reviews of the XL Pipe electric water heated floor are confirmation of the high quality and reliability of the product.

Among the tangible advantages of products from this brand are the following characteristics:

• high maintainability;
• overheat protection;
• absence of electromagnetic radiation;
• possibility of laying pipes according to any pattern;
• simplified floor screed.

What coating is compatible with underfloor heating?

In addition to answering the question: how much does a warm water floor cost, owners are faced with other dilemmas. Most often they touch on the topic of design compatibility with various types of floor coverings. Based on the principle of operation of heated floors, it can be assumed that the most effective solution would be to choose flooring with maximum heat capacity.

The first type of coating is protected from deformation and has sufficient heat transfer, so it is often used in rooms with high level loads.

The tiled covering for a warm water floor will be durable and practical.

Although laminate and parquet do not have the same wear resistance as tiles, they do have a number of other positive qualities - good heat conductivity and a simple installation process. Thus, water heated flooring under a wooden floor can also be implemented in the house. Linoleum can also be used in different rooms, it is worth remembering that the maximum thickness of a warm water floor should not exceed ten centimeters.

The owner can consider each of the options and determine which coating is best for a warm water floor after assessing the layout of the house and the resources available.

Installation of a warm water floor

The main aspect of the proper functioning of the heating system is proper installation. You can do it yourself or use the services of companies that offer turnkey installation at an affordable cost. It is worth understanding that professional installation water heated floor - the price for the work of which is about 30% of the cost of consumables, is more preferable to installing the system yourself.

The rather high cost of a warm water floor per 1 m2 should not confuse property owners who are thinking about implementing an energy-efficient and reliable heating circuit. The fact is that the substantial initial investments required to purchase components and pay installers are justified over time reliable operation systems and low costs associated with the operation of heated floors.

Choosing a heated floor

Description of the types of heated floors, their pros and cons, as well as tips for choosing a heated floor...

The use of heated floors is common not only in cold latitudes, but also in areas with a continental climate. This heating system allows you to heat the rooms evenly; be independent from housing and communal services, save space in the room, and also warm floors have a positive effect on the human body.

There are two types of heated floors: water and electric. The second type of heated floors is divided into two more methods of electric heating: convection electric floors and infrared.

So should you choose electric or water heated floors?

Advantages of water heated floors

The advantage of water heated floors is their efficiency, since they are connected to a common heating system and can significantly reduce energy costs for heating the room. Different types of fuel and energy can be used to heat water. If you live in a private house or cottage, when installing a water-heated floor you will have to take care in advance heating boilers, since the load on them increases significantly.

In an apartment building with central heating, installing a water-heated floor is quite problematic. If you do not have individual heating in your apartment, you will not be able to install a water heated floor.

Disadvantages of water heated floors

The disadvantage of water heated floors is the reduced service life if the heated area is more than 60 square meters. The next disadvantage is its complexity and high cost of installation. When installing it, you will have to fork out for pumps, filters, and pipes. And yet, if one section or segment of the pipeline is damaged, it will not be possible to disconnect only part of the system, since the pipelines are connected in series. And if the boiler that heats the water stops working, then the water-heated floors will simply be useless.

Electric option is the most popular way of arranging heated floors. Cable system heating has increased reliability, and the high resistance value allows the cable to heat up even at low current, giving off heat to the floor covering.

Advantages of electric heated floors

An electric heated floor is easy to install; it can be laid in a concrete screed, and the screed can be decorated with a special parquet board or ceramic tiles. The heating temperature can be set using a thermostat, which is easy to control. You can adjust the temperature in each room individually. Electric heated floors do not require maintenance, and they are quite durable. At correct operation the service life can be 50 years.

Disadvantages of electric heated floors

But, despite all the advantages, it is worth saying a few words about the disadvantages of electric heated floors. They require significant energy expenditure when heating large areas, which means heating a spacious house or apartment can cost a pretty penny. In this situation, it is more profitable to use water heated floors. An electromagnetic field is also formed, but due to the shielding braids it is insignificant.

Both water and electric floors have their pros and cons. The main thing when choosing is to take into account many factors: your budget, the size of the room and even the location of the furniture in the room. Taking into account all the nuances, you can choose what you need.

Repairing an apartment without the proper skills is quite a difficult task, and yet, quite often, out of all types of repair operations, homeowners undertake wallpapering the walls. Read the instructions on how to hang wallpaper yourself...

The most common option today is considered to be a warm water floor, the use of which allows you to completely warm up floor surface to the required temperature, without having visual heating devices. In addition, parquet, laminate or linoleum can be laid on top of such a system without any problems. You can read more about warm water floors here (http://www.a-comfort.ru/montazh-teplyh-polov.html)

Warm floors are an effective solution among all the options that contribute to room heating. This system has gained great popularity due to the fact that installation does not require much effort and time. A warm water floor is a structure, or rather a network of pipelines through which water flows, heating up to 35 degrees Celsius. This type of heating is often preferred by urban homeowners, since there is no need to use water from the central heating system. But such a system can also be installed in country houses, in which a heating boiler and a special water pump are installed. The "warm floor" system can work not only from gas boiler, but also from a heat pump.

Such heating has many advantages that make it possible to distinguish a water-heated floor from a radiator heating system.

The heat is distributed evenly throughout the room, making your stay in the room comfortable.

Very often, the feet freeze first from the cold, and with the help of an installed water heated floor, this problem can be eliminated by providing warmth.

Cold air rises.

Saving energy consumption, which is very good when the room area is large.

If such a system is installed by specialists, the customer pays only for their work and the materials used. After this, you will not have to spend money on maintaining the heated floor.

IN winter period The system helps to heat the room, and in summer - cools it.

When installing a “warm” floor system, you can forget about heaters and radiator pipes.

But, no matter how good everything is, such a system also has a number of disadvantages that need to be considered in more detail:

The main disadvantage when installing a water floor is that if there is a need to obtain a relatively low heating temperature, you need to have mixing unit, working in conjunction with a water pump, which creates forced circulation of water flowing through the pipes.

In addition, often the use of a water heating system can lead to the fact that the total pressure in central heating at home will begin to decline.

It is important to know that after the water passes through the loop pipes, it enters another room in a cooled form, which leads to insufficient heating.

Today, it is possible to install a water heated floor only with permission from the responsible authorities, who must give their consent to use. Do not connect yourself this type heating without the necessary sanctions.

It is best to consult with specialists who install and maintain water heated floors before installing such a system.

But in general, it should be noted that such a heating system will become an indispensable assistant during the cold season. In addition to the fact that it is hidden from prying eyes, it consumes little electricity, and it also surpasses many heaters in quality.

Peculiarities

In private houses and cottages, water-heated floors are increasingly being used, the opinions and reviews of buyers about which are ambiguous. To decide on the rationality of using such a design, you should understand some of its features:

• Warm floors are part of a water heating system, so they can be installed in country houses and cottages or new buildings if they have heat exchange risers or autonomous heating. In apartments of old houses this type Underfloor heating is prohibited.
• The design is a “layer cake”, quite complex in execution. Installation requires certain experience and a high degree of qualification.
• When pipelines are damaged, a leak occurs, and the location of the breakdown is difficult to identify. To repair the area, it is necessary to dismantle the floor.
• Not all types of finishing coating are suitable for heated floors.

What are the reviews from users?

“The process of installing built-in underfloor heating is truly an amazing thing, I did it in my home. I hired contractors for installation - the floors turned out like something out of a fairy tale. General heating operates at minimum mode, the rooms are warm and cozy. The bathroom is absolutely classy, ​​there is no such dampness and the water dries quickly on the tiles. Even with the heating turned off, the cold floor does not cause any discomfort.”

Igor, Moscow.

“I installed heated floors throughout the entire area of ​​the apartment to use as the main option without radiators. I laid ceramic tiles on top in the hallway, bathrooms and kitchen, and laminate flooring in the rest of the rooms. The room thermostat regulates the operation of the boiler, while the system copes well with heating - an economical and convenient type of heating.”

Anatoly, Nizhny Novgorod.

“In the house, I heat the entire first floor only with a water-heated floor system - there are no radiators. Very warm even in very coldy. The main disadvantage is the price. Laying technology and materials are much more expensive more expensive than batteries, plus special thermostatic mixing pump groups. It’s better to hire specialists to carry out the work – this is also an additional cost.”

Konstantin, Volgograd.

“Heated floors have increased comfort compared to radiator heating - this is undeniable, but they also have a number of disadvantages. I have floors like this in my bathrooms, hallways and bathhouse. At temperatures below 25 °C, I heat the floor in the bathhouse to 30-35 °C - it’s hot for the feet. I visit the house periodically, so I lower it to 15 °C. The radiators can warm up the house to 22 °C in 4 hours, and heated floors in 8. In the summer I encountered the problem of a cold tiled floor.”

Alexander, St. Petersburg.

“I have a big house, I installed heated floors in all the rooms. They didn’t turn it on the first year, they started it up only the next year – the winter was harsh. The radiators were turned off, the temperature in the rooms remained 21-22 degrees - it was warm to walk on the floor even without slippers. The average monthly gas consumption turned out to be 1.7 times less than with radiator heating.”

Danil, Samara.

“I have been installing floors under the floor for quite some time. parquet board. I would like to note that Maximum temperature on the surface of the parquet should be no more than 27 ° C, and you should definitely avoid laying a warm water floor under the furniture. With good ventilation and insulation external walls the temperature in the room will be 24-25 degrees, taking into account floor heating to 27 °C without additional sources heating".

Maxim, Moscow.

Let's sum it up

The main role in the effectiveness and feasibility of using a warm water floor is played by the finishing coating (linoleum, ceramic tiles, laminate, parquet or engineered boards). You should choose materials with medium or high thermal conductivity, otherwise all the heat will be “extinguished.” Ceramic tiles are considered the most heat-conducting option, but some reviews indicate excessive “coldness” outside the heating season.

According to reviews, a system of warm water floors under laminate can only be used if Special attention choice of finishing coating:

• load class 31-33, thickness 8-10 mm;
• the presence of special pictograms or inscriptions on the labeling - “Underfloor heating” or “Warm Wasser”, “H 2 O”;
• safety class E0-E1.

The following are suitable for installation on a water floor system: Quick-Step Creo (Belgium), Tarkett Woodstock Premium (Russia), Pergo Living Expression (Sweden), Classen Futuro Harmony (Germany) and others.

Many consider floor heating as the main heating without the use of radiators, but for such a design to be effective, all necessary measures must be taken to thermally insulate the walls and roof of the building. Owners of private houses and cottages note the rationality of warm water floors for the first floor of a building with a basement. Warm water floors create increased comfortable conditions in the premises of a house and apartment due to the large heat transfer surface.

Electric heating

Advantages of electric floors

This system, as the name suggests, runs on electricity.
It uses cables made of special alloys as a heat conductor. The current passing through the wires heats the cables, and from them the surface of the floor and more are heated. The ability to organize several temperature zones is the main advantage of an electric heated floor. The first zone is directly above the floor surface (+24°), the second is 1.5-2 m from the floor (+22°) and the third is under the ceiling (+20°). This regime fully meets the needs of the human body.

Warming up the room and distributing temperature flows in the room with a traditional radiator and warm electric floor

Electric floors are designed for long-term use. They are less susceptible to external mechanical influence, which distinguishes them favorably from water floors.

The electrical "warm floor" system has the following advantages:

1. It can be used indoors in conjunction with central heating.
2. Since the air is heated by thermal radiation, the air in the room does not become dry.
3. Does not require additional equipment As a result, costs are reduced.
4. Thanks to thermostats and temperature sensors, you can control the temperature and set it as you wish.
5. Installation of film heated floors does not require major repairs to the base, and the installation mesh of heating mats can be cut if necessary.

An interesting fact is that, according to scientists, the use of infrared floors not only reduces energy costs, but also increases human immunity. Under the influence of infrared rays, microorganisms and cells vibrate. Due to this, vital processes are stimulated, and well-being improves. It's up to you to believe this statement or not.

Disadvantages of electric floors

Electric flooring is not suitable for large spaces because the efficiency of using electricity as heat is quite low.

The larger the area of ​​the room, the greater the energy consumption for heating it. Water systems here look more economical. In addition, laying electrical elements (cable or film) under furniture is impossible due to the high risk of their failure due to overheating. However, the rod floor shown in the photo does not have these disadvantages.

Cables in heated floors warm up evenly, but this is their disadvantage: this can affect the arrangement of furniture and the choice of finishing floor covering. Thus, cable floors will work best with self-leveling floors, tiles and ceramic tiles, film - with laminate or linoleum.

Resistive heating cables cannot be cut. Therefore, before installation, you need to accurately calculate the length of the wire.

The negative aspects of using an electric floor include:

• Increased energy costs.
• When using an electrical system, electromagnetic radiation inevitably occurs, which can negatively affect the health of particularly sensitive people and the environment in the room.
• Installation without your own hands is quite expensive.
• Laying wires requires precise calculation of the pitch, so it will be difficult to do without some experience.
• The cable floor is laid in a screed. If you are renovating old apartment, then the costs of refurbishment of floors will increase.
• Infrared floors are expensive.
• Heating mats should not be placed under household appliances and large furniture.

Only by considering all the positive and negative qualities of the electrical underfloor heating system can you decide which better view use: cable, matte or film.

Water heating

Pros of water floors

Water heated floors are a modernized design of water heating. Water enters the pipes from the autonomous heating system. A mandatory requirement is the presence of a pump, since without it the liquid will not be able to circulate through the system.

A significant advantage of a water floor is the low cost of the coolant. Water at low cost provides high quality heating of premises.

Water heated floors have the following advantages:

1. Can be installed under almost any floor covering, including natural parquet.
2. Reliability of system operation.
3. Electricity costs are significantly reduced.
4. Possibility of use as the main heating system, which allows you to abandon visible heating sources (batteries, convectors, etc.).
5. Installing a water floor is cheaper than installing an electric one.

Cons of water floors

Like any heating system, water floors are not without certain disadvantages:

• It cannot be installed in an apartment building without permission from the relevant authorities. The fact is that if such floors are connected to central system heating, then temperature losses for the remaining apartments increase. It is prohibited to connect to a common heating system without permission from housing and communal services.
• They require the purchase of additional equipment (circulation pump, manifold, mixing unit, etc.).
• Damage to communications is possible, which will lead to leaks. Therefore, when purchasing pipes, you must first figure out what material they are made from and which one is better suited for the “warm floor” system.
• Complex installation that requires certain skills in laying pipes, pouring and leveling floors.
• Since the water floor is filled with cement-sand mortar, in the event of a breakdown, the entire screed will need to be dismantled.
• A competent calculation of the system power is required. In case of errors in the project, the consumer risks being left without heating.

polprofy.ru

A water heated floor is a room heating system from a boiler or from a boiler. The pipes are laid on the base and must be filled with concrete screed.

Advantages of water heated floors

The main advantage of this design is that the room is heated evenly and heat loss is significantly reduced, which means fuel is used economically. In addition, you don’t have to install radiators, which will give you the freedom to implement many design ideas.

Warm floors of this type are often installed in country houses or cottages, as well as in apartments with autonomous heating. If the house does not have an automatic boiler, it is better not to install water heated floors. IN ordinary apartments, such a floor cannot be made, since it is prohibited by law; in this case, electric heated floors are installed.

Disadvantages of water heated floors

The disadvantage of water heated floors is that leaking pipes can lead to the need to break the floor, although the service life of pipes that are used today is 50 years. In addition, you cannot lay any kind of floor covering on the floor; ceramic tiles are best suited, as they have high thermal conductivity. Parquet in this case will not be a suitable covering, since wood transfers heat very poorly.

Technology for laying water-based heated floors

Water heated floors are installed only inside a cement screed. To install it correctly you need professional knowledge, skills and experience. An important step works are carrying out all necessary calculations. It is very difficult to do this yourself, since it takes into account the dimensions of the room, what the floors are made of, the presence or absence of insulation, what power the boiler is using, as well as the diameter of the pipes and the type of flooring.

Conclusion

If you decide to make a water heated floor, it is better to entrust this work to professionals, otherwise there is a risk that you will not get the desired result.

Warm water floor - the main differences from other types of heating

The “warm floor” heating systems that exist today are divided into two subtypes: electric and water. According to the method of application, such systems can act as the main source of space heating or be auxiliary heating equipment. Often electric heating elements used for local heating of technological rooms, balconies, loggias, bathrooms and toilets. On the contrary, a water heating circuit can be installed throughout the entire apartment or used in one of the rooms, for example, in a children's room.

This heating option is usually chosen in corner rooms, where there is a high probability of cold zones appearing. Thanks to its operating principle, this heating option is able to provide the most comfortable temperature conditions. Despite the fact that, in comparison with other heating methods, water heated floors have their pros and cons, in the general context this type of heating deserves more attention. In any case, there are always aspects and situations in everyday life that allow one to evaluate the advantages of the system, or, conversely, that indicate the technical imperfection of the chosen option.

For reference: a floor equipped with a water circuit allows the use of a wide variety of floor coverings, unlike electric mats.

For example: in order to maintain normal circulation in a home heating system using heated floor technology, you will need to install not only a pipeline, but also install additional equipment. Circulation pump, a manifold - mixer, a whole set of three-way valves (according to the number of water circuits), all of these are mandatory attributes and accessories in this case, regardless of the heated area. The presence of special devices will avoid a drop in coolant pressure in the central heating circuit and prevent interruptions in circulation hot water household use.

It should also be remembered that such a system is prohibited for installation in an apartment building, which was originally designed for centralized heat supply. For private sector residents and owners country houses On the contrary, this option is preferable to traditional heating options.

You need to know that in order to implement this type of heating in your house or apartment, it will require considerable costs associated with a large amount of work and consumables. The drawings and diagrams show the temperature conditions inside the room, achieved as a result of using a thermal curtain and when operating the heated floor covering of the system.

It is clearly visible on the basis of what principle heating is carried out internal space. In the case of a water floor, the heat source is located in the lower part of the room. Thereby thermal energy spreads evenly over the entire floor area, transmitting to air masses circulating inside the living space required heat. When using radiator heating, during which internal air exchange occurs due to convection, the floor is the coldest place in the living room.

Insufficient heating, especially in corner rooms and with a large glazed surface, is compensated by installing additional heating devices. A water floor is fully capable of solving this problem, uniformly heating the entire internal volume of the room. It is also important aesthetic side question. The absence of heating radiators has a positive effect on the quality of the interior of residential premises. A warm floor distributes heat evenly throughout the entire space, thereby heating all objects in the room.

For reference: the most acceptable indoor temperature for comfortable living is + 18 0 C. By heating the coolant in the water heating circuit to a temperature of +35-45 0 C, it is achieved optimal temperature heating the floor covering 25 0 C. Accordingly, the lowest floor layer of air heats up more, while the upper layers have a comfortable temperature.

Warm floor design. Scope of application

The main advantage that you should pay attention to when studying a heated floor heating system is cost-effectiveness and high efficiency. Large interior spaces, especially in private houses, designed for autonomous heating, can be successfully heated in this way. Even the installation and arrangement of heated floors in all residential premises of a large multi-room residential building will be a completely profitable enterprise. For that category of citizens who have water gas heating or expect to use solid fuel units, a water floor is practically perfect option solving the issue of organizing heating.

Comparing this heating scheme with electric floors is inappropriate in this case. The latter option, even taking into account the comparative ease of installation and ease of operation, is clearly inferior to a water floor in terms of economic indicators. The electric floor can be installed in selected places, where there is a need to heat small areas.

Before summing up the advantages and disadvantages of a water heated floor, let’s try to understand its design and technological features.

The basic principle of operation in this case is as follows:

• heat source - coolant liquid, boiler water, which can flow into a pipeline laid in the floor;
• heated water can come either from the riser of the central heating supply line or from an autonomous heating device.

Thanks to design features and new technologies, today there are several ways to equip heated floors. As an ideal floor covering, it is best to use ceramic, concrete or combined materials (tiles, decorative stone, concrete screed). The advantages and disadvantages in this situation are subjective. Ceramic tile or concrete screed have high thermal conductivity, and accordingly, when heated by the heated coolant, they transfer heat better into the room. Conversely, laminate, parquet, and linoleum are convenient and comfortable floor coverings that play the role of additional insulation, reducing the intensity of heat transfer in internal spaces.

The efficiency of a warm water floor directly depends on the quality of the layer cake, i.e. on the composition of the underfloor heating substrate. The substrate usually includes:

• Waterproofing;
• Metal mounting mesh;
• Thermal insulation;
• Damper tape;
• Dry or wet screed.

On a note: As a rule, the traditional thickness of a layer cake varies in the range of 50-150 mm. The final parameters of the cake are determined depending on the diameter of the pipes for the water circuit, the thickness of the floors, the quality of the floor covering and the power of the underfloor heating system.

The main operating tool in this case is a pipeline made of metal-plastic pipes. Pipes connected into separate fragments or sections (circuits) are laid on a cushion, after which they are connected to collectors through which coolant is supplied to the heating circuit and returned.

The design of the heating system also contains the operating principle. The distance between the screed and the floor covering is where the warm water circuit is laid, through which the entire surface of the floor is heated to the required temperature. Due to insignificant heating (the optimal heating temperature of the coolant is 35-45 0 C), the “warm floor” heating system is low-temperature.

Obvious advantages of heated floors

If you do not take into account installation difficulties, heated floors are rightfully considered one of the most effective systems heating The low-temperature operating mode of heated floors can provide real and significant savings in heating costs. On average, 20-40% compared to the radiator heating option. The absence of overheating of the air mass indoors ensures good saturation of the internal space with positive ions.

To others obvious advantages The following qualities can be safely attributed:

• high environmental safety of the system, full compliance with sanitary and hygienic standards for heating residential premises;
• the main part of thermal energy is transferred as a result of thermal radiation, which has a positive effect on the human body;
• real heat savings in residential buildings with high ceilings(up to 50% for ceiling heights of more than 3 meters);
• the absence of open wiring and radiators greatly simplifies interior decoration residential premises;
• real subsequent savings in heating costs compared to electric heating(on average 5-7 times);
• Unlike electric heated floors, a water floor does not produce a powerful electromagnetic field that negatively affects the well-being of the inhabitants of the home.

Obvious disadvantages of this heating system

The main drawback that can overshadow you if you decide to install heated floors in your home is rather the presence of administrative prohibitions on the use of such a heating system. You can get around the prohibitions if you are focusing on a small heating area and you have a ground floor. Otherwise, the situation is fraught with further administrative fines and restoration of dismantled equipment.

The second argument that can be attributed to the disadvantages of this heating system is the lengthy and painstaking installation of the equipment. The disadvantage of a water floor during installation is the involuntary weighting design features building. Due to the layer cake used for the substrate, the weight of the ceiling can increase by 10-15%, which is extremely dangerous for residential multi-storey buildings old building.

Following installation and installation technology, homeowners will have to face quite large financial costs. Unlike electric floors, water heated floors are labor-intensive in the process of maintenance and repair. In terms of safety, a water floor is inferior to other home heating options.

Conclusion

There are many advantages to this heating system, but there are also some disadvantages when it comes to heated floors. However, the situation looks like this. In any case, if you decide to install warm water floors in your house or apartment, the advantages that you will receive in the future will clearly outweigh the disadvantages. High efficiency, efficiency and practicality are the main advantages of this heating system.

Peculiarities

Water heated floor systems are a fairly new solution in the field of built-in heating systems. The peculiarity is that the coolant in this case is heated water circulating through pipes laid in the floor, which transfers heat radiated through the decorative flooring into the room.

At the same time, the efficiency of water heated floors is high; this type of heating seems to be extremely economical, allowing one to reduce the cost of heating a home to a comfortable temperature by 20-30, or even 50%. It's all about the temperature of the circulating fluid, which, as a rule, does not exceed 50⁰C, and often 40⁰C is enough.

Why? It's simple. The floor in a room, in the case of a heated floor, is a continuous convective surface that radiates heat. At the same time, the floor covering remains pleasant and comfortable, without posing a risk of burns, and the air in the room is heated evenly over the entire area.

Unlike traditional heating radiators, a heated floor immediately warms the air to comfortable temperatures below (22-24⁰С), while at head level the temperature is already somewhat lower (18-20⁰С), and an overheating zone does not form under the ceiling, no overheating occurs. empty heat losses. This property is one of the advantages of water heated floors, as it provides optimal “healthy” heating that promotes comfort and health.

Like any type of heating, water heated floors, of course, have their own advantages and disadvantages. And this must be taken into account when deciding whether to install this type of heating system.

The undoubted advantages of water heated floors include the following:

1. Economical– compared to radiator heating from 20-30% to 60%. When heating water to low (30-50⁰C) temperatures using gas in autonomous systems, especially with large heated areas, a water floor is even superior to an electric floor in terms of operating costs (up to 5-7 times more economical).
2. Safety, because the pipes with the coolant, firstly, have a low temperature, and secondly, they are completely hidden. This eliminates the risk of injury and burns.
3. Comfort, ensured by uniform heating of the air and pleasant tactile sensations when walking on the floor barefoot.
4. Aesthetics, because the built-in system solves the problem of hiding or camouflaging unaesthetic radiators and opens up wide horizons for the implementation of design ideas for remodeling and interior arrangement.
5. Smooth and soft heating, safety for capricious floor coverings due to gradual heating and low temperatures, absence of thermal shock (in the case of installing a thermostat and the ability to control the temperature of the coolant).
6. No generation of harmful electromagnetic field and oversaturation of air with positive ions.
7. Water heated floor does not dry out the air in the room.

While listing the advantages of water heated floors, it is worth analyzing its disadvantages:

1. Labor intensity of installation– to lay a water floor, you will have to undertake a major overhaul with leveling and careful preparation subfloor surfaces. The system consists of several layers of different materials, including waterproofing, cement-concrete screed and decorative flooring.
2. Significant initial costs for installing a hydronic floor option- approximately 5 times higher than electric or traditional radiator. However, with active use, water heated floors demonstrate high efficiency and pay for themselves.
3. It is impossible to install heated floors, for example, on stairs and in small corridors. In such areas it is required additional installation radiators.
4. The likelihood of a leak and the difficulty of eliminating it– to find damage and repair the pipeline, you will need to completely dismantle the floor covering and remove the screed.

Due to the risk of leakage and, accordingly, flooding of neighbors below, water-heated floors are not recommended for installation in multi-storey buildings. Also, when connecting water-heated floor circuits to the central heating system, there is a high risk of pressure drop in the system throughout the house and a sharp decrease in heating efficiency.

Is it enough to analyze the information on the query “water heated floor advantages and disadvantages” to make a final decision, especially if people with poor health live in the home? On the one hand, if the difficulties do not frighten you, but the advantages captivate you, it is worthwhile to critically evaluate them again.

The fact is that the very main feature and advantage of this type of heating, namely, constant elevated temperature flooring, which allows you to “keep your feet warm” all the time, may also have a downside.

Namely, to provide negative impact on the vascular system of the legs, because blood constantly flows to the “warm” legs, putting a constant load on the veins and expanding them.

Therefore, it is recommended to install a water or electric floor in rooms with periodic and short-term presence of people there, or to limit the time they walk on the floor or stay on it.

The question of whether heated water floors are harmful to the general physical condition and well-being cannot be answered unambiguously. The air in the room is not overdried, there is no improper mixing of layers, but in the case of heated floors it is difficult natural ventilation. In order to avoid air staleness, it is necessary to ventilate the room more often and take care of forced ventilation.

Conclusion

Water heated floor is an effective alternative to radiator heating and a good option for first floors, private houses. However, making a decision about installation requires a scrupulous analysis of the pros and cons.

If we have not made heating systems with water heated floors before, then it will not be right to immediately take on the practical implementation of our desires. You need to first pay attention to some theory. Well, at least learn about the pros and cons of heated floors. Perhaps the disadvantages will be such that you won’t want to have such a heating system in your home at all.

What are the advantages of water heated floors compared to radiators?

Disadvantages of water heated floors

1. Heat loss rooms where heated floors are installed must be less than 100 W/m2.

   Conclusion: with higher heat losses, you will have to either insulate the house or install combined heating (water heated floor plus radiators).

2. It is not always possible to install water heated floors in apartment buildings, where single pipe systems heating. Well, or at least you need to know how to make such a connection correctly and without any conflicts with neighbors or utility workers (this is described in detail in the article about installing a water-heated floor in an apartment).
3. Large thickness of concrete screed over a warm floor. If such heating is on the second floor or higher, then the floor level will rise by ~10 cm. On the first floor or on the ground floor, the total is more - by 14-20 cm. In other words, when planning heating with water heated floors in an old apartment (house), be prepared to other global works related to the reinstallation of doors. And further: concrete screed a warm floor will increase the load on floors and other structures... are you sure they will withstand it? What is your confidence based on? Think about it.
4. Installation of a water heated floor and materials for it are more expensive than for radiator heating. True, these expenses are then paid off by saving energy resources, as I wrote about above.

There are several more disadvantages of heated floors that must be taken into account. I will list them.

1. Any heated floor (not necessarily water-based) is not the best heating system for rooms where people are constantly present. Surprised? I'll explain why. Alas, almost everything in the world has a downside.

So, contrary to the same well-known saying (or proverb? - I can’t remember what the difference is), your feet do not always need to be kept warm. I mean, not all the time! Blood rushes to heated areas of the body, this is well known to everyone. And the legs, being warm all the time, do not rest, the veins do not rest... The result is a disease of the veins due to their constant expansion.

Conclusion: you need to stay in a room with a heated floor for a limited time. That is, do such heating in the hallway, bathroom, in any passage corridor, in the bathhouse, in the dressing room... where you are rarely or for a short time.

2. I mentioned the lack of mixing of air layers in the advantages of a warm floor. But this is also a minus, because it is impossible to provide normal natural ventilation. But with radiators, natural ventilation is possible.

   Conclusion: when designing heated floors, design and forced ventilation with all its “charms” (connection to the power grid, noise, additional expenses... this is for you in continuation of the theme of efficiency), otherwise the air in such a room will be stale.

3. Not every material can be used to cover a heated floor. Therefore, you need to know the following.

   It is necessary to distinguish between two concepts that are similar in sound, but different in meaning: “comfortable floor” and “warm floor”. What is the difference?

   What is the difference?

   The comfortable floor has a temperature of 20…22 degrees and is only suitable for off-season use. But in real winter cold it will not cope with heating. And then you will need additional heating (radiator, air, or something else). Wood is quite suitable for covering a comfortable floor.

   But in warm floor The coolant heats up to 55 degrees. And you can’t cover such a floor with wood! Tree from high temperature will crack. But if you don’t heat it, then, again, such a heating system won’t cope in cold weather.

   And although there is a separate section about coverings for heated floors, I will say a few words here. As coverings for heated floors, you should take only natural materials: carpet from natural material, ceramic tiles, linoleum - also from something natural, and not from PVC, parquet and parquet boards, etc.). Non-natural materials contain different harmful substances, which will evaporate when heated... however, they evaporate even without heating. Do you need it?

Well, I believe that now, knowing all the pros and cons of water heated floors, you will be able to make an informed choice, and not “because that’s it.” Next we will consider the question energy saving when heating with water heated floors.
