Underfloor heating system. Electric heated floor. Installation of a water-heated floor on a concrete base

Description:

For the last 70 years, the Swedish company Wirsbo, which has existed for almost 4 centuries, has been producing pipes, purposefully improving the materials for their production: steel - 1934, polyethylene - 1955, metal-plastic - 1968 and cross-linked polyethylene PEX-A - 1972.

For the last 70 years, the Swedish company Wirsbo, which has existed for almost 4 centuries, has been producing pipes, purposefully improving the materials for their production: steel - 1934, polyethylene - 1955, metal-plastic - 1968 and cross-linked polyethylene PEX-A - 1972. PEX-A had excellent physical, chemical and mechanical parameters, so the very first rolling of pipes made from this material was a stunning success. This was an event that changed the status of the company and revolutionized the construction communications market. In 1973, Wirsbo PEX Gmbh was organized in Germany, which became the first company to manufacture products outside of Sweden. Currently, Wirsbo has 5 factories located in Sweden, Germany, USA, Spain, Canada and annually produces 77 million m of pipes sold in 55 countries.

Wirsbo has been active in Russia since 1992. The pipes of this company were used in the installation of sanitary systems in public infrastructures of Moscow (Central Telegraph, Domodedovo Airport, Luzhniki Stadium, etc.), St. Petersburg, Novosibirsk and other cities, in the construction of multi-storey residential complexes and cottages.

Today, about 1 million objects with Wirsbo underfloor heating operate flawlessly around the world. The growing interest in these systems is associated with their undoubted advantages. The main advantage is the use of water circulating through the heating circuit from Wirsbo-pePEX pipes as a coolant.

Water has a high heat content per unit volume and can be heated by various energy sources (electricity, oil, gas, coal, etc.). It is clean, non-toxic and always available, including at a price. Low temperature water (the most economical temperature parameters at the system inlet and outlet 55/45°C), at which the systems operate underfloor heating, helps save energy. At the same time, ineffective heat losses from pipes on the way from the heat source to the heated space are reduced.

Wirsbo systems compare favorably with floor-mounted systems that use electricity as a coolant in the absence of additional load of electromagnetic fields.

Compared to other heating systems (for example, radiator heating), which use the same coolant, namely water, underfloor heating is characterized by a different method of heat distribution. The company's many years of practical experience show that underfloor heating, due to the participation of the entire floor surface in heat emission, provides exceptionally uniform horizontal temperature distribution and close to ideal vertical distribution. Thus, the most optimal climate is created in the rooms: the floor temperature in the rooms fluctuates between 22–25°C, and the air temperature at head level is 19–22°C. These are the most favorable life conditions, which is confirmed by independent psychological tests showing that people feel most comfortable if their head is slightly colder than their feet.

The formation of thermal comfort in the premises is ensured high level thermal radiation pleasant to humans, constituting 50–70% of the heat flux. A combination of thermal radiation and slow convective heat flow is best technical solution, providing the benefits of underfloor heating.

Unlike radiator heating, the floor system does not contribute to positive air ionization, which is unfavorable for humans, and when used, which is very important, optimal air humidity is maintained. Floor system hygienic, since with minimal heat flows, dust practically does not circulate in the room. It is invisible, suitable for modern design, and in the absence heating devices there is an opportunity for more rational use areas of residential or office premises.

And finally, it is necessary to note the economic factor: with underfloor heating, in comparison with radiator heating, thermal energy is saved by 20–30% in residential buildings, and in rooms with high ceilings (gyms, exhibition halls, church complexes) this figure can reach 50% .

Meanwhile, the advantages of water underfloor heating consist of the total influence of the coolant and individual elements of the system, which includes pipes and component equipment. Wirsbo underfloor heating systems use specially developed Wirsbo-pePEX and Wirsbo-evalPEX pipes made from PEX-A polyethylene with an anti-diffusion barrier that blocks the penetration of oxygen into the system and protects its steel elements from corrosion.

Anti-diffusion barriers are applied to the Wirsbo-PEX main pipe and topped with a protective layer to prevent possible damage when installing Wirsbo-pePEX pipes.

Pipes are reliable in operation:

Do not become clogged or overgrown due to the smooth surface on which chemical and mechanical deposits are not deposited;

Resistant to corrosion and aggressive environments;

They have low thermal conductivity, ensuring slow cooling of the water in the system;

They have low sound conductivity, ensuring silent operation of the system;

They have a low coefficient of resistance when liquid moves through them and provide a high speed of its transportation;

Durable, have high coefficients of resistance to fatigue and mechanical loads, and are resistant to abrasion;

Durable, trouble-free operation for at least 50 years.

The pipes are easy to install:

They have flexibility, allowing the pipe to be bent to the appropriate angle by cold bending;

They are light in weight and supplied in coils of 60, 120, 240 and 480 m, which are easy to unwind when laying underfloor heating loops;

Easy to cut and process with simple tools;

The pipes are marked with a double green stripe to prevent kinks.

Other parts of the system, such as manifolds and fittings, are made from special dezincification-resistant brass.

The system operates on the principle of supply and return manifolds, each loop being controlled at both ends. The valve on the supply manifold can be equipped with an actuator, which is controlled by a room thermostat or manually. Control valves are built into the return manifold, which control the flow of water through all loops, thus equalizing pressure drops. The control equipment (thermostats and actuators) reliably provides room temperature control based on the opening and closing of the water flow (on/off control).

Water heating system is a multi-layer structure that is installed on concrete or wooden floors. It must meet all standards for thermal insulation, sound insulation and strength. For new buildings with self-leveling concrete floors The underfloor heating system is designed as a “wet installation” system. It contains layers: concrete slab, waterproofing (especially necessary for slabs in contact with the ground and in wet rooms), sound and heat insulation, film, pipes, concrete screed, cement layer for leveling the floor and coating. The heating loops in this version are located in concrete mixture. Concrete conducts heat well, and this self-leveling layer serves as a screen to distribute heat over the floor surface. In old buildings, when self-leveling floors cannot be installed, the “dry laying” method is used. Heating pipes installed in the insulation of the supporting layer in special aluminum plates, which ensure uniform heat distribution. This reduces the number of heavy layers and the height of the structure. The Wirsbo-Alu system has been developed specifically for these purposes. The thickness of the insulating layers and the materials used vary depending on the industrial purpose of the construction projects.

Underfloor heating pipes are laid into the heating circuit in various ways. The most optimal is the “snail” circuit, since it ensures uniform temperature distribution. With this method, the difference in temperature under the supply and return pipes practically unnoticeable. The “coil” circuit is easier to install, but it is advisable to use it in deep rooms or in the presence of a cold wall.

Fastening of pipes in circuits is also carried out in various ways. Fastening using reinforcing mesh and wire, or fastening tape and mounting brackets, is simple and has the additional benefit of increasing the strength of the mechanical floor screed when reinforced. In addition, thanks to the mesh, the pipes will be completely recessed in the concrete, while guaranteeing maximum heat transfer. The second method is to fix the pipes in special guide rails. Pipe installation is easy and quick.

The last, most important layer of the structure is the coating.

The materials used for these purposes and their thickness affect the transfer of heat into the heated room. Therefore, when choosing flooring It is recommended to use thermal resistance indicators R as a criterion, which are: for ceramic tiles and marble - 0.02 m 2 K/W, synthetic flooring - 0.075 m 2 K/W, parquet and carpet - 0.10–0.15 m 2 K/W. At higher values ​​(more than 0.15 m 2 K/W), floor coverings will act as thermal insulation. It is also necessary to ensure that the floor coverings and the adhesive used to secure them can withstand prolonged exposure to temperatures of approximately 50°C.

The underfloor heating system can be used for installation in residential and public buildings, production premises, gyms, etc. The durability of these systems is estimated at more than 50 years. In addition, the use of low-temperature parameters and a high degree of radiant component of the heat flow allows for significant savings in thermal energy. And finally, the most important proof of the advantage of this system is the comfort in your home.

One of the disadvantages of classical heating is appearance radiators. They will not always look harmonious in the room and take up useful space. Therefore, in some cases they prefer to install other heat supply devices. You can make rational and practical floor heating in an apartment or house using certain circuits, pipes and convectors.

Advantages and disadvantages of underfloor heating

This water floor heating in an apartment differs from the standard one in the design and methods of installing radiators. Their heating surface is located below the finished floor level. For convection air flow The upper plane of the heat supply device has a grille.

All hot water lines are also hidden under the floor. In fact, the user sees only the upper radiator grille. The air is heated through it. There are also differences in design.

The heating convector in the floor has an oblong shape. The tubes through which the coolant flows are connected to the housing using heat exchange plates. Most often they are made of copper.

Properly installed water floor heating with your own hands should have the following advantages:

  • Minimum space requirement. Unlike batteries, the entire volume of the room remains free;
  • Creation of a thermal air curtain. To reduce heat losses, water floor heating in the house is installed at window designs and external walls. Radiators heat the air in areas of the lowest temperatures;
  • Good appearance. In fact, water heating of floors in a private house will look harmonious in any interior.

Disadvantages include uneven heat distribution. Such systems are not recommended for installation in large rooms. To achieve optimal effect, a heating radiator built into the floor must have a fan to increase air convection. This affects the overall noise background. Thermostats and programmers must be installed to automatically control the operation of the system.

Analyzing reviews of floor flooding, we can come to the conclusion that it is a source of dust concentration. Therefore, for this type of heat supply it is necessary to carry out wet cleaning more often.

Types of floor heating convectors

At the first stage of design, you should choose the right heating radiator built into the floor. They differ not only standard specifications power, but also design. Also important has the material of manufacture.

First, the required power is calculated. The basis is the heat loss in a house or apartment. Then the optimal model of the floor heating convector is selected.

He must have the required performance characteristics– maintain the nominal pressure and temperature of hot water.

For installation, you will need to do preparatory work with a rough coating. Effective heating in the floor with your own hands is done only after insulating the rough surface.

Choice wiring diagram largely depends on the design of floor radiators. They come in the following types:

  • Floor e. Located directly on the surface. The advantage is the simple connection of the water heated floor to the heating system. Pipes can be placed on top of the wall. Disadvantage – unsatisfactory appearance;
  • Built-in. They are mounted directly into the floor on rough surface. IN visible area only the grate remains. Installation of heating in the floor is complicated, as this leads not only to a decrease in the height in the room, but also to the mandatory adaptation of the materials used to high temperatures.

Schemes for water floor heating in an apartment with wall models are not considered. They are no different from standard ones and have the same properties.

To increase the degree of convection, a fan can be included in the package. This will improve uniform heat distribution throughout the room. However, the cost similar models differs to a large extent.

Currently, there are a number of manufacturers whose products are suitable for DIY water floor heating. First of all, we should highlight convectors German company Kampmann. Depending on the required parameters, heating convector models built into the floor may have two or three pipes. In the latter case, the rated power of the device increases.

Models of heating radiators built into the floor from the Polish company Verano, the Czech Minib and the German Kermi have no less good performance properties. To organize budget heating in the floor with your own hands, you can consider the products of the Ukrainian company Teplobrend and Carrera.

An additional function of water floor heating in a private house can be cooling in the summer. To do this, you need to connect to the chiller system.

Heating floor schemes

Having chosen the optimal model of a heating radiator built into the floor, you can begin to draw up a diagram of its installation. At this stage, it is important to take into account its operational and technical features.

Heating schemes for installing underfloor heating are practically no different from standard ones. The difference lies in the choice of installation method for pipes and radiators. They must be hidden under the floor. Therefore, it is necessary to select the material for the floor in advance - insulation, underlay and decorative surface.

When choosing a scheme, the following factors are taken into account:

  • Height of heating convectors that will be built into the floor;
  • Pipe material. Polymers cannot be installed in a concrete screed. Their thermal expansion can affect the integrity of the line. Special sleeves are required for installation;
  • Inspection hatches. After connecting the water-heated floor to the heating system, free access is provided to the joints of the pipelines. This is necessary for carrying out repair and maintenance work;
  • Installation air valves, Mayevsky taps and thermostats. The most difficult thing is to provide access to these heating elements. The scheme for water heating of floors in a private house should take this factor into account.

Most often, the choice is made on a closed two-pipe heat supply. It will ensure normal temperature distribution and is the most optimal in terms of labor-intensive installation and selection of components.

For connecting copper pipes of heating radiators built into the floor with polymer pipes you will need special adapters. Contact of copper with other metals can lead to oxidation of the joint.

Installation of floor heating convectors

Correct installation of duct convectors is preceded by preparatory work with the floor. It is necessary to make a niche where the heating devices will be installed. It is best to do this at the repair stage.

The dimensions of the niche should be 5-10 cm larger than the dimensions of the heating device. This is necessary for the normal connection of the heating radiator after it is installed in the floor. An additional layer of thermal insulation is installed. For guard decorative surface It is recommended to form a niche using concrete pouring.

At this stage, pipes should be installed in order to later connect to the radiator. They are installed on the floor, taking into account possible thermal expansion. For extended sections of the main line, it is necessary to install compensation thermal loops.

The further installation steps are as follows.

  1. Installation of heat-reflecting material. This will help improve convection and reduce heat loss.
  2. Installing the heating convector tray into the floor. If there is none, a substrate made of heat-resistant material is installed. The radiator should not hang.
  3. Connecting pipes to the heating system. It is important to select the correct adapters to ensure a reliable and durable connection.
  4. Installation of decorative grille.

After the final installation of the heating in the floor, a test run of the system is performed. It is first necessary to perform pressure testing. The coolant temperature should be increased gradually. The same applies to pressure. At this stage, the absence of leaks in the water heat supply to the floor is checked with your own hands, and the operating modes of the thermostats are set.

One of the common mistakes in installing convectors without a tray is filling the niche construction foam. Its pressure can lead to deformation of the structure.

Features of operation of underfloor heating

Before each heating season, it is necessary to check the integrity of system components. Almost all reviews about underfloor heating indicate a large number of dust and dirt in niches. They should be cleaned periodically.

During operation, the thermostat parameters may change. Since it will be hidden behind a decorative grille, it is necessary to check its condition. Otherwise, the likelihood of system malfunction will increase. In addition, the integrity of the connection of the water heated floor to the heating system is monitored. In such schemes it is difficult to control the occurrence of leaks.

In models with a fan, the power line is laid in advance. To improve comfort, it is recommended to make a remote switch. Clogging of the fan rotor is also common. It must be cleaned before each heating season.

The video shows an example of installing a duct convector in an apartment:

Underfloor water heating, unlike radiator heating, which is familiar to most people, appeared relatively recently.

This system is designed to heat the floor in an apartment or house, using it as a heat accumulator and heat emitter at the same time. Floor heating allows you to evenly distribute thermal energy and achieve significant savings (up to 30%).

Among the undoubted advantages of water heating, one can highlight not only efficiency, creation comfortable temperature and more efficient use living space (due to the lack of traditional radiators), but also the possibility of do-it-yourself installation.

This article is entirely devoted to describing the operating principles and sequence of installation of water heating.

Installation of warm water floors

Floor heating allows you to evenly distribute thermal energy and achieve significant savings. Click to enlarge.

Water heating flooring implies the use of a heated coolant as the main source of thermal energy, which heats the room by passing through pipes laid in the floor.

Warm water floors can most often be found in country houses. Similar situation arose due to a number of compelling reasons.

Firstly, in an apartment connected to the system central heating, it is prohibited to install heated floors due to the threat of increasing hydraulic resistance.

Secondly, you should not connect to the pipelines of the hot water supply system, since the water, after passing through the heated floor system, returns to the common hot water supply riser already cooled.

Thus, in a city apartment it is most advisable to use an electric heated floor, and in country house- water. Water heating of underfloor heating should be used exclusively in insulated buildings and premises.

It is not necessary to carry out preliminary waterproofing work (most component manufacturers do not insist on this procedure).

Types of water floors

Water heating installed under the floor can have the following varieties:

  1. Concrete.
  2. Flooring.

The first option involves laying a water floor using concrete screed, the second - without laying the screed.

Flooring can be installed on aluminum plates through a polystyrene underlay (polystyrene system) or on a wooden subfloor or joists (wood system).

In this article we will dwell in detail on the installation sequence of a concrete water floor, since it is this that received greatest distribution and popularity.

Typical composition of a water heating system

Almost any heating system that includes a warm floor (water) is represented by the following main elements:

  1. Polymer or metal-polymer pipelines.
  2. Thermal insulation materials.
  3. Circulation pump.
  4. Shut-off valves (ball valves) and control valves (control valves).
  5. Manifolds, fittings and fasteners.

A heating system that performs an auxiliary function can not only be installed with your own hands, but also requires independent preliminary calculations.

Composition of the heating system. Click to enlarge.

In the case when the main source of heat is heating, represented exclusively by one water-heated floor, the development design solution It is recommended to order from specialized specialists.

The main stages of installing a concrete water floor

Water floor heating produced independently (with your own hands) must necessarily include the sequential implementation of the following stages and operations:

  1. Installation of a collector group.
  2. Preliminary preparation of the floor surface.
  3. Laying heating system pipelines.
  4. Temperature adjustment.

Let us consider the main issues related to the implementation of the above work.

Installation of a collector group

Work on installing a water floor must begin with the installation of a special manifold cabinet, which should be located at an equal distance from the end consumers.

So, if it is necessary to install heated floors in two rooms, then the manifold cabinet should be installed in the middle of the rooms.

To achieve the required aesthetic effect, the manifold cabinet is installed inside the wall.

The preparatory operation in this case is the preparation of a special niche, carried out using a hammer drill and a grinder. The dimensions of this niche should be slightly larger than the overall dimensions of the cabinet, and it should be located near the floor surface.

What is the main purpose of the manifold cabinet?

The system (main or auxiliary) of water floor heating includes a certain number of pipelines that are connected exactly inside the manifold cabinet, coming from the central heating system. Regulating and shut-off valves are an indispensable attribute of manifold cabinets.

Collector device. Click to enlarge.

After directly installing the manifold cabinet, it is necessary to install two main pipelines into it - supply and return.

The supply pipeline is used to transport coolant from the system central water supply. The cooled coolant returns through the return pipeline.

Shut-off valves (ball valves or valves) are installed at the end sections of the supply and return pipelines located in the manifold cabinet.

Their main purpose is to forcibly shut off the coolant supply. To join shut-off valves A transitional compression fitting is applied to the supply and return pipelines.

The resulting system, consisting of a supply and return pipeline, shut-off valves and a compression valve, should be connected to a manifold rail with whole line outlet pipes.

These pipes are used to connect the pipelines that form the heated floor contour. The hole formed on the other side of the manifold manifold pipe remains open.

This hole can be closed using an ordinary plug or an inspection drain valve, which is also designed to bleed air bubbles when the system is “aired.” As you can see, the installation of the manifold cabinet can be done with your own hands.

Preliminary preparation of the floor surface

A water floor installed directly from a central heating system must be laid on a previously prepared surface.

Surface preparation should begin with removing debris and checking the surface for horizontalness, carried out using a two-meter building level.

Checking for horizontalness should never be neglected. It must be done in order to protective layer the screed was the same, and the heating was uniform.

You should start leveling the floor if the heights located in the corners exceed one centimeter. Next, the waterproofing layer is laid (if necessary) on the previously leveled surface.

The walls should be taped around the entire perimeter with a special damper tape designed to compensate for linear expansions to which a warm floor (floor screed) is subject. Any remaining tape left after pouring the floor must be cut off.

Preparing the floor for heating installation. Click to enlarge.

Heating, which is a water-heated floor, necessarily includes heat-insulating mats that prevent heat loss.

Floor heating can be installed using mats made from the following materials:

  1. Expanded polystyrene.
  2. Mineral wool.
  3. Aerated concrete.
  4. Technical jam.
  5. Velotherm.

Thermal insulation mats that protect the floor located in a bathroom or toilet with self-installed water heating from heat loss must be moisture resistant.

Pipeline installation

The installation of pipelines for a water heating system in a country house or apartment, as well as all other stages, can be done with your own hands.

The main point of this stage is securing the pipelines of the future thermal circuit, which contain all the heated rooms.

One of the most popular methods is to attach a pre-laid pipe to a metal masonry mesh laid directly on the insulation.

Fixation of pipelines, which contain water floors heated by a coolant heated to the required temperature, and metal mesh is carried out with knitting wire.

Warm floors may include a thermal circuit, the maximum possible length of which does not exceed 70 meters. In cases where it is not possible to meet this distance, heated floors must have a second circuit.

The process of laying pipes for heated floors. Click to enlarge.

To install a dual-circuit system, a collector rail with a large number of outlets should be used; the total length of the pipelines of one circuit should not exceed the length of the pipelines of the other.

Pipelines must be laid from the coldest zones towards the warmer ones. Cold areas include window and door openings.

When installing heating yourself, you should choose pipes from the most reliable supplier.

Hydraulic tests of laid pipelines must be carried out before pouring the floor with cement-sand mortar.

Pipelines are considered to have passed the test if, at a pressure of 6 atmospheres, no leaks are detected and no pressure drop occurs. Time required for complete hardening cement-sand mortar, must be at least 10 days.

Options for laying pipes in heated floors. Click to enlarge.

Only if these conditions are met will the water heating you install under the floor be reliable, durable and efficient.

Temperature adjustment

Floor heating using heated water (water) provides two ways to adjust the temperature:

  1. Manual regulation (using shut-off valves).
  2. Automatic regulation (using electric drives).

Warm floors (in particular, the water heating we are considering) are more efficient when automatically controlled.

Final provisions

It is more rational to install water floor heating in a house rather than in an apartment. The latter option has a right to exist, but is associated with some problems.

In both the first and second cases, it is quite easy to install the system yourself, using the sequence of actions described above and some specific nuances.

Today, heated floor technology is not much inferior in efficiency to radiator heating systems, but has many advantages. We propose to consider the main advantages of hidden heating systems, installation and connection features.

Advantages of hidden heating

One aspect of the attractiveness of underfloor heating systems is the concealment engineering communications. Neither radiators, nor heating pipelines, nor shut-off and control valves will disturb the harmony of the interior. However, this is not the only advantage of the secrecy of the heating system.

If in living rooms pipes do not pass through the wall ceilings and along them, this will greatly facilitate installation finishing works. For leveling and application decorative materials The entire plane of the walls is accessible; in addition, there are no difficulties with cutting the floor covering; there is no need to hide the passage of pipes during installation suspended ceilings. The absence of visible communications is especially beneficial when changing layouts.

In addition to aesthetic advantages, there are also technical ones: uniform heating of the floor creates optimal scheme distribution of warm air. Since the main emphasis is not on convection heat transfer, but on its direct radiation, there is no need to warm up the upper uninhabited zone. This ensures a reduction in heating costs of about 10-15%. What’s most interesting is that savings here do not come at the expense of comfort: the temperature in the leg area is about 20-22 ºС, in the head area it is 3-4 ºС lower.

The main disadvantages of water heated floors

The main disadvantage of a heated floor system is the complexity of its design. Laying process heating elements in the floor is quite technologically advanced and labor-intensive, but if we are talking about a water heating system, additional difficulties arise with organizing the piping and setting up the heating operation.

This is not at all a reason to refuse to use heated floors. Using quality materials and installation system, compliance with the technology of laying pipes in the floor and installing floor coverings, all efforts will pay off handsomely. Underfloor heating is a truly effective, economical and durable heating system, but, we repeat, only if it is designed in compliance with a number of key requirements.

Among the difficulties of the device, it is worth mentioning separately the need to carefully select the material for the floor screed. In addition to strength qualities, it must meet standards for heat capacity and thermal conductivity, as well as the ability to emit heat in a certain spectrum - about 9-10 microns. In principle, when heated to 40 ºС, almost all cement-bound materials emit heat in this range. All that remains is to achieve the highest possible density of the coating and uniform distribution of thermal energy in the warm layer of the screed. For this purpose it can be used steel fiber, liquid glass or special polymer additives for underfloor heating screed - plasticizers C-3, HLV-75, BV 3M and the like.

Materials for the device

As already mentioned, underfloor heating systems require extremely careful selection of materials. Just one and a half to two decades ago, everyone was content with laying in the floor metal-plastic pipe, convincing yourself that nothing threatens the heat exchanger in the floor other than corrosion. This approach has a number of disadvantages that become apparent during the first 3-5 years of operation.

In order not to repeat the mistakes of others, for heated floors you should use tubes that, if damaged, can restore the structure of the polymer over time and have the highest possible thermal conductivity. It is impossible to guarantee that when installing the tubes they will not be broken, but for metal-plastic this, without exaggeration, is a death sentence. The best way In this regard, cross-linked polyethylene behaves, the alternative to which is copper. In the latter case there is a series additional benefits: even higher thermal conductivity, a miniscule coefficient of thermal expansion and the ability to remember shape during deformation.

For open heating systems, the lack of excess pressure can lead to the ejection of gas molecules through the walls of the tubes; over time, gas particles can accumulate into fairly large plugs. To exclude such phenomena, modern pipes for heated floors they are made of composite materials with a built-in oxygen barrier.

When it comes to materials for installing heated floors, insulation cannot be ignored. Its choice is decisive for the durability of the heating system and the floor as a whole. The thermal barrier must be incompressible, retain its shape and, naturally, have high resistance to heat transfer. Of all the options, extruded polystyrene foam and polyurethane foam are most suitable for use as a thermal cutoff; polyisocyanurate boards are less commonly used.

Do you need a backup heating system?

You can often hear the opinion that water heated floor systems are unreliable, and therefore when using them as the main source of heating, there is an illusory risk that over time the house will be left without a single source of heat. This misconception is associated, first of all, with the experience of operating underfloor heating systems, which, in essence, are budget counterfeits of the original technology.

Judge for yourself: if low-quality pipes are used for the heat exchanger, the risk of their clogging, breakage and destruction of the screed due to thermal expansion increases significantly. Here it really makes sense to combine floor heating with the installation of radiators, although this version of the heating system is fraught with adjustment difficulties: you constantly have to adjust the flow, otherwise the temperature in the room increases to truly uncomfortable values.

However, if a warm floor is designed taking into account all technological requirements, it can work as the main heating system for many decades. Care and sensitivity during the installation of thermal insulation, pipes and when pouring screed eliminate the main risk factors for both the occurrence of leaks and damage to the floor covering or the base on which it is laid. In general, the costs of organizing a backup heating system and correct device water heated floors are approximately equal.

Preferred types of boilers

The main disadvantage of water floor heating systems is their extremely low resistance to overheating. This rule mainly applies to heat exchangers made of polyethylene - this material has one of the highest coefficients of linear thermal expansion. For copper pipes this figure is significantly lower.

Due to such restrictions, the correct selection of the boiler unit and appropriate adjustment of its operating mode are required. Boilers running on natural gas and electricity are considered the most suitable. Their thermoregulation system eliminates the supply of too hot coolant to the underfloor heating system.

Solid fuel boilers can easily be called the least suitable for connecting a water floor heating system. Their peak power is almost impossible to limit, especially when periodically changing the type of fuel. That is why such systems require inclusion in the hydraulic circuit special devices that maintain the water temperature in the heating circuit by mixing liquid from the return line.

Connection diagram

The final argument against underfloor heating systems is the complexity of organizing the coolant distribution scheme. If the system has more than one floor heating circuit, the installation of hydraulic manifolds with flow regulators is required.

House heating scheme with water-heated floors. A - gas heating boiler; B - combined mixing unit and collector group; B - heated floor contour. 1 - boiler with built-in circulation pump; 2 - security group; 3 - expansion tank; 4 - three-way valve mixing; 5 - circulation pump; 6 - ball valve; 7 - needle valve or valve with a servo drive; 8 — pressure reducer; 9 - flow meter

On the one hand, installation and commissioning of such complex networks is comparable to additional costs. However, all the efforts to organize heating with underfloor heating are more than compensated by the comfort of its use: each room can easily adjust its own thermal regime, while the entire system can be easily and efficiently balanced even if there are several dozen “loops”.

Otherwise, the heating floor connection is made according to classic scheme organizations closed system heating with excess pressure. The only addition is the water preparation unit at the make-up inlet: since the heat exchanger consists of fairly narrow channels located at the lowest point of the system, it is necessary to remove from the water all mechanical impurities that can settle and eventually completely clog the tubes.

Heat production always becomes more expensive. In each part of the Russian Federation it is necessary to heat the house during a special period. Every sensible resident wants to know how to modernize the housing system. The website contains a large number of heating systems dwellings that use completely different methods of generating heat. Each heating system can be installed individually or hybridly.
