The choice of heating method for a garage depends on the following factors:
- length of stay of the hosts in winter;
- cost of equipment;
- energy availability, price;
- Ease of use.
We suggest you consider various options solution to the issue and figure out how to do the most economical and efficient heating DIY garage.
The better to heat or the choice of energy carrier
In 99% of cases, garage buildings are not connected to centralized heating networks or main gas, so owners have to choose autonomous heating methods. To heat a garage, you can use 4 groups of energy carriers:
- various types of solid fuel - firewood, coal, briquettes, agricultural and other combustible waste;
- diesel fuel, waste oil;
- electricity;
- liquefied gas in cylinders.
Advice. When you start choosing an option for heating a garage in winter time, keep in mind an important pattern: the more expensive the energy source, the easier and cheaper it is to organize heating that is convenient to use. Conversely, cheap or free fuel in the form of waste and garbage will bring a lot of trouble - labor costs and initial financial investments.
Solid fuel combustion
Wood and various waste are the cheapest fuel for heating, and in some cases it is available completely free of charge. In the southern regions, which are not rich in forests, another type of fuel is widely used - small agro-industrial waste.
For reference. Agricultural waste consists of small particles sifted from grain crops. These are pieces of stems, weeds chopped by a combine, straw and other waste. The energy price is very attractive and starts from 20 USD. e. for 1 ton.
After cleaning grains, waste remains that is used for heating If you decide to heat your garage with solid fuel in the winter, get ready to deal with the following issues:
The gain is in money and excellent heating of a room of any size, the losing points are listed above. Add here the time for kindling and warming up (0.5-1 hour). Hence the conclusion: cheap heating solid fuel is suitable for owners of garages and boxes who stay there every day for 4-6 hours or more.
Use of mining and diesel fuel
Heating a box or garage with diesel fuel purchased at a gas station is expensive and extremely unprofitable. An exceptional option is heating small area rooms where work is carried out using a portable heater, whose characteristics are described.
Oil waste – more economical in financially energy carrier, although not the cheapest. This option can be seriously considered when used oils can be obtained at a reduced price. What are the features and pitfalls here:
Note. Due to their cheapness and simplicity, the oil miracle stoves shown in the photo have become especially popular. They tend to shoot flames when the fuel contains a small amount of water or antifreeze, causing a fire.
The advantages of using mining are high heat transfer, quick ignition and warming up of the garage box, ease of use (it’s easier to add oil than to chop and carry wood). The conclusion is this: if fuel is inexpensive, or you spend a little time in the garage, then liquid fuel- a suitable option. The initial investment is comparable to wood heating.
When using diesel fuel, it is worth considering the option of a factory-made diesel air heater of the “Planar” type, shown in the photo. With a fuel consumption of 250 ml in 1 hour, the unit develops heat transfer of up to 2 kW. There are also more powerful heaters - 3 and 4 kW with diesel consumption of 0.37 and 0.5 l/h, respectively. Price – within 330 USD. e.
Autonomous diesel-powered air heaters designed for cars Electrical heating
Heating with electricity is the most comfortable and cheapest option in terms of initial investment. But during operation you will have to pay the full tariff - it makes no sense to install a two-zone meter, you are not going to work in the garage at night.
Let's list all the advantages of electric heating:
There are only two disadvantages, but they are critical: the price of electricity and the limitation of the power consumption limit, which does not allow installing an effective heat source. For example, if in an agreement with management company If the figure is 3 kW, then a convector with only 2 kW is installed, which is not capable of properly heating the garage in winter.
For reference. Sometimes car enthusiasts use homemade “goats” and fan heaters in the pits, despite the restrictions. Why you can’t do this: there is a danger of the wiring catching fire, the neighbors’ voltage drops, and if employees check the electrical networks, you will face a large fine or shutdown.
Electric heating is an option for short stays in the garage. They came, turned on the heater, completed the intended work in 1-2 hours, turned off the heating and left. If you have turned the room into a workshop where you conduct work time, you will have to pay significant amounts for energy consumption.
A standard wall convector heats the air in the room much slower than a fan heater Gas heating
This method of heating a vehicle storage space is acceptable for residents of the Russian Federation, where the retail price of liquefied gas is quite low. It will be too expensive for Ukrainians to heat their garages with propane.
Autonomous heating from gas cylinders as safe and comfortable as electric. Moreover, in the Russian Federation the cost of energy is lower. But there are a number of pitfalls here:
If you add up the financial costs, the problems of organizing such heating and refueling cylinders, then the negative aspects will cover up some of the positive aspects of ease of use.
A comparison of the cost of 1 kW of heat obtained from various energy sources in the conditions of Russia and Ukraine has been published.
How to organize air heating
This heating method involves direct heating of the air in the garage from a selected heat source. This can be any of the following units:
- solid fuel stove;
- furnace - dripper in production;
- electric heater - convector, oil radiator or heat gun;
- gas convector.
Note. We deliberately do not include in the list heating units that emit combustion products directly into the room - diesel stoves of the Savo type, heat guns direct action and gas infrared heaters. Look through any automotive forum and see that users in the reviews complain about headaches and poor health from inhaling exhaust gases.
Such heaters emit diesel combustion products directly into the room Installation of a wood-burning and exhaust stove
Direct heating of air in a garage by burning cheap fuel - firewood and various waste - is the most economical way heating. But you need to organize it wisely, otherwise the heater will heat one corner of the room, while the opposite one will remain cold. It is clear that you cannot install a stove in the middle of the room, which means that the issue of heat distribution must be solved differently.
To make effective air heating of a garage or box with your own hands using a wood stove, use our recommendations:
- Order, buy or make your own economical stove, and not just an iron box with a pipe. You will find examples of stoves with drawings, diagrams and assembly instructions.
- The heat exchange surface area of the heater walls must correspond to the dimensions of the room. The calculation is as follows: in order to add logs at intervals of 3-4 hours and evenly warm up a 20 m² garage, the heating surface area should be 1 m².
Convection fins are welded to the furnace body, increasing the surface area and improving heat transfer - The part of the housing around the ash pan is not taken into account (it heats up slightly). But the area of convective fins welded to the walls from the outside is taken into account.
- Install the potbelly stove in the chosen location and be sure to organize airflow around the case with any fan - household, for hoods or a computer cooler. Thanks to the forced air movement, heat is more efficiently removed from the walls of the firebox and distributed more evenly throughout the box.
Options for blowing a wood stove with a fan - Before venting to the street, lay the chimney horizontally along the wall, so it will release more heat into the room.
- Raise the chimney pipe to a height of 5 m, counting from the grate, and equip it with a damper to adjust the draft. Provide a condensate collector at the bottom; adjust the cap at your discretion.
Layed horizontally chimney allows you to increase the heat exchange surface area and improve room heating
Note. Calculation of the heat exchange surface area of the stove is taken from practical experience our expert Vitaly Dashko. The calculation is correct for garages with a height of no more than 3 m.
There are designs homemade stoves, designed for air heating of workshops, garages and other outbuildings. Below is a diagram of a potbelly stove made from a gas cylinder and equipped with a separate heating chamber through which air is blown by a fan. If necessary, water can also be driven through the heat exchanger.
Advice. If you have recently replaced a floor-standing gas boiler in your home, do not rush to throw it away. Take it old unit into the garage, connect it to the chimney and heat it with wood, pumping air into the empty water jacket using a cooler (from the bottom pipe). Then you won’t have to cook the oven.
All of the above applies equally to. The only difference is the placement of the fuel tank that feeds the dropper. Keep the tank away from the stove to prevent fire. Do not use a regular two-chamber miracle heater - it is a fire hazard and consumes up to 2 liters of waste per hour. Use models with a drip burner.
Placement of electric heaters
The first thing you need to do is to choose the right electrical heating appliances based on power. If you want to heat the entire garage, then measure its area and multiply the resulting quadrature by 0.1-0.15 kW. That is, a box of 20 m² will require 20 x 0.15 = 3 kW of thermal power (and it is equal to electrical power), sufficient to maintain positive air temperatures.
Different heating methods can be combined. For example, it makes sense to hang an infrared panel above a workbench to provide local heating. Heat the rest of the garage with a stove or a heat gun - whichever is more profitable. Don't forget - it is necessary when burning any type of fuel.
Water heating system
You need to understand what to install water heating makes sense when you are in the garage all the time. Otherwise, the costs will not justify themselves, because in addition to a source of heat and fuel, you will need to buy:
- cast iron or steel batteries (as an option, weld registers from pipes);
- circulation pump;
- expansion tank;
- pipes on the main line;
- non-freezing coolant - antifreeze.
For reference. The garage space is heated periodically, so the system cannot be filled with plain water.
Knowing the need for the amount of heat to heat the room (calculated in previous section), or determine the length of the pipes of a homemade register using the table:
In the table, t1 means the coolant temperature, t2 means the air in the room The calculation method is as follows. Let's take it steel pipe DN 80 (Ø89 mm) and we find out from the table that 1 m of length is enough to heat an area of 1.37 m². We take the square footage of the garage, for example, 20 m² and divide by this figure: 20 / 1.37 = 14.6 m - the total length of the heating part. We distribute it among 2-3 heating devices and cook the registers according to the drawing.
Use the circulation pump at the lowest pressure (4 m water column), expansion tank– minimum volume. Pipes - polypropylene, steel or metal-plastic, size DN 15. Then install radiators on 2 opposite walls and assemble a simple two-pipe system heating closed type connected to a heat source according to the diagram:
Advice. Do not forget to add a filter to the circuit - a mud filter and Ball Valves to cut off the heat source and drain water from the system. IN top point install an automatic air vent, and on the batteries - Mayevsky valves for bleeding air.
Why we do not recommend making a system in the garage open type, as simpler and cheaper? The reason is antifreeze, which will evaporate from an open tank, which is unsafe for health (ethylene glycol is poisonous), not to mention the price of the coolant.
Western European experience
If you type the phrase “garage heating” in the search and look at pictures on English-language sites, you will not find any wood-burning or oil-fired stoves in Western European garages. How do local motorists warm themselves:
We have already discussed the first 2 options above. The third method is also far from new: water heated in the boiler passes through a radiator, blown by a powerful axial fan. Ideally, the unit is suspended from the ceiling and distributes hot air throughout the room.
The advantages of this option are compactness, heating speed and the possibility of air conditioning in summer period(cooled water is sent to the radiator instead of heated water).
Heater made from a car radiator There is one downside - increased costs for equipment, because the coolant must be heated in the boiler and supplied through pipes to the heater. But if the garage is attached to a private house, then the problem is easily solved by connecting the radiator to the building’s water heating system.
Reference. Many garage craftsmen already use such heating, installing a homemade analogue of a heater made from a car radiator and any suitable fan. How this is implemented, look at the video:
From all of the above, as well as on the basis of practical observations, the following conclusions suggest themselves:
- Despite all the difficulties with burning solid fuels, firewood and other waste occupy a leading position among energy sources due to their reasonable price.
- For the same reason, most garages have air heating. It is simple to implement and allows you to quickly warm up the room.
- Air heating is made more effective by forced blowing of the heat source or pumping air through the heating chamber.
- Water heating is more appropriate in workshops and car services; for a private box the system is a bit expensive.
- Electric garage heating is an auxiliary or short-term option that is easy to implement, but difficult to pay for during operation.
Whatever method of garage heating you choose, the degree of insulation of the building will play a big role. An iron frame with slots in the gates does not retain heat at all and cannot be heated, so heating it is expensive and pointless. Another thing is that the walls are made of foam blocks or insulated on the outside with polystyrene foam; savings when heating such a garage are quite achievable.
Most car enthusiasts use the garage not only for its intended purpose, but also as a room where they can take a break from household chores, do hobbies or do some household chores. To ensure that your stay in the garage remains comfortable in winter, the room must be heated somehow.
To make heating economical, you need to know the features existing methods heating, since you can choose the optimal one for yourself only taking into account the specific situation and a number of factors: the dimensions of the room, its distance from housing, the availability of fuel consumed, the budget for providing the garage with heat, etc.
Heating options for a standard one-car garage
The most popular and most economical method is heating the garage with electricity, especially if the building is located some distance from the house, has small dimensions and is not visited often in winter.
There are several ways to heat a garage using electricity.
Convector
Models of electric convectors for use in garages and other premises technical purpose
A reliable and efficient device, the operating principle of which is based on air convection initiated by heating elements - cold air enters the device from below and, heating up upon contact with the heating element, rises warm to the top.
Convectors are available in floor-mounted, wall-mounted or universal versions - on support legs, with brackets for mounting to the wall, or equipped with both mounting options. The latter version is especially convenient, as it allows you to compactly place the heater on the wall with the possibility of quick dismantling and installation next to the car - at the place of repair.
Advantages of an electric convector:
- quick heating to working condition;
- heating in automatic mode - a certain temperature value is manually set, upon reaching which the device turns off and resumes heating the room only when it cools down air environment by an amount of 1 degree;
- safety of operation and ease of routine maintenance;
- durability;
- Possibility of use in rooms with high humidity and pollution, since the operating elements of the device are covered with a protective housing.
Disadvantages of the convector:
- higher cost compared to some other types of electric heaters (quartz);
- the effect of operating a convector in a garage is achieved after at least half an hour;
Portable fan heater increased power floor-mounted for household and industrial needs Operating principle: a heat exchanger (heating elements or coil) is heated by electricity, air from the room is pumped into the heater by a fan, passed between the heating elements and returned hot to the garage.
Advantages of a fan heater:
- environmental friendliness - the absence of any emissions into the surrounding space during operation;
- ease of adjusting the heating intensity - there are switches for heating modes (turning off some heating elements) and fan rotation speeds;
- small dimensions and mobility - can be installed anywhere in the garage;
- the possibility of focused heating of zones or objects;
- quick heating of the room;
- equipped with automatic shutdown devices in case of overheating or overturning;
- possibility of additional independent configuration with an electromechanical thermostat for automatic maintenance set room temperature;
- low cost of electrical appliances of low and medium power;
- ease of operation and maintenance.
Like any unit, The fan heater also has disadvantages which must be taken into account:
- accompanying heating, a decrease in air humidity in the room;
- the presence of dust accumulation on heating elements, fraught with fire or, at a minimum, unpleasant smell in the garage;
- noise caused by the operation of the fan;
- increased electricity consumption.
Despite these disadvantages, the use of a fan heater is the most popular heating option for a garage.
Lightweight Timberk heat gun with handle for easy movement A compact and easy-to-use device that provides quick and effective heating of the garage. It differs from a fan heater in the significantly higher power of heating elements. The device is based on electric heaters and a high-performance fan, which provides intensive air flow to the heating elements, causing rapid distribution of heat in the room.
Connecting high-power heat guns requires a three-phase power supply with a voltage of 380 V; less powerful units are designed for 220 V.
In small garages, the use of heat guns creates dust in the air, so they can be used effectively only if the room is constantly kept clean, including through high-quality finishing of the enclosing structures.
Infrared heater
Infrared heaters in various designs: tripod, wall and ceiling The operation of the device is based on the emission of infrared rays, which, upon reaching the surface of objects along the propagation path, heat them, and they, in turn, give off heat to the room. Such devices are sometimes called UFO heaters, but UFO, the common Cyrillic abbreviation of the same name in everyday life, has nothing to do with ultraviolet irradiation.
UFO heaters are available in various sizes and power; they can be on a leg or designed to be attached to a vertical or horizontal base (wall, ceiling). Provided the housing is waterproof or placed under a canopy, infrared heaters can also be used in front of the garage on the street.
Pros of IR heaters:
- economical electricity consumption;
- ease of operation and installation;
- reliability, safety and environmental friendliness.
The disadvantage of infrared heaters when used in limited space garage is the effect of infrared rays on a small area, which causes less heat transfer from objects into the air. But when focusing radiation in the direction of the actual zone, these heaters are quite effective.
Important! The significant heating of the housing of UFO heaters during operation requires caution when handling the device in a cramped garage.
Water heating of a large capital garage
The most familiar to consumers, the use of which in spacious garages is justified by many factors, including the possibility of do-it-yourself installation. If the cost of purchasing a heating boiler, radiators and other components does not bother the garage owner, then water heating is the best way to heat a large permanent garage.
- advantages - high level automation of the heating system, when using natural gas— constant availability of energy in the main line, efficiency and high efficiency of gas equipment;
- disadvantages - the presence of a danger factor of explosion, fire or carbon monoxide poisoning.
Using gas heating The owner of the building must especially strictly observe the safety requirements in his garage.
A good option for a garage is an automatic steam-drip condensing unit, which is up to 15% more economical than other models, as it can operate efficiently at low gas pressure. In the heat exchanger of such a boiler, water from heating with a gas burner turns into steam, and then condenses again into a liquid state, which is accompanied by the release of heat. Such boilers are produced in floor-mounted and wall-mounted versions. For a garage, the second option is preferable, eliminating the possibility of tipping over when performing some work.
Electricity
Heating with an electric boiler is enough for a garage expensive solution heating problems. If alternative type If there is no fuel, it is better to use electrical appliances (convectors, fans, heat guns, UFO heaters - described in detail above).
When using electric heating equipment indoors with open heating elements (coils, heating elements), it is necessary to remove flammable and combustible materials (fuels, lubricants, solvents, paints, tow, etc.) from the garage.
Long-burning pyrolysis boiler Atmos made in the Czech Republic To date solid fuel boilers are in demand among homeowners and industrial buildings along with gas equipment. The fuel is coal, sawdust, and firewood. This is a fairly economical heating system that provides the room with heat well.
Disadvantages of heating a garage with a solid fuel boiler:
- need for smoke removal;
- the need to allocate a significant area for arranging a fuel storage area, which is not always possible in a garage;
- the danger of having anything in the garage that could ignite from a spark when the firebox door is opened;
- the need to regularly clean the firebox from ash and the pipes from soot.
The most advanced, and therefore economical, type of solid fuel boiler is a pyrolysis type unit, where the fuel is exposed to high temperatures decomposes into two components - pyrolysis gas and ash, each of which is burned practically without residue in a separate chamber.
Most models of pyrolysis boilers use only wood, pellets and waste (not bulk) from the woodworking industry as fuel. However, universal units are also produced that are also designed for the use of coal and peat briquettes. The only common conditions for all models is that in order for the boiler to enter the pyrolysis mode, the fuel humidity should not exceed 20%, otherwise it will work like a conventional solid fuel heater.
However, pyrolysis-type boilers are expensive equipment, and therefore not every consumer can afford to use them to heat a garage - heating a garage with your own hands is truly economical only when all components of the process do not require significant costs.
For a clearer idea of how to equip a garage with a stove, you can watch this video:
It’s not difficult to build a stove by watching the corresponding video.
Processing as a type of fuel
There are special stoves that use as fuel, the consumption of which is up to 1 liter per hour.
The disadvantage of this heating method is the need to purify the oil in special installations (you can make it yourself), since burning waste lubricating fluids without first adapting the fuel to the process can lead to failure of the furnace.
Air heating system for garage
It is not as popular among garage owners as a water heater, but with its help you can not only heat, but also ventilate the room.
The method consists of equipping the garage with an air duct with deflectors through which air is supplied, pumped by the fan of a heat gun or fan heater and additionally passed through an air filter.
The main advantage is the rapid simultaneous drying of the entire volume, which prevents the aggressive effects of moisture on the car and other furnishings.
To reduce heating costs, the owner is recommended to insulate the outside walls and ceiling of the garage, having previously sealed all the cracks and holes. For thermal insulation of walls, you can use foam sheets, and expanded clay for the ceiling and floor. The use of mineral wool slabs will require subsequent waterproofing
A properly selected garage heating system will not only provide comfortable temperature regime indoors, it will protect the enclosing structures from dampness, but will also prevent the development of corrosion on the metal parts of the car, which is detrimental to equipment.
Given its simple installation and minimal number of permits, an electric boiler for a garage is the optimal heating solution. When choosing, pay attention to the operating principle, installation requirements, and required power.
Types of electric boilers installed in garages
To choose the right electric boiler for your garage, you need to understand the operating principle used and the associated limitations during operation. There are three types of boilers, differing in their internal structure and principle of heating the coolant:- Heating element boilers - belong to heating devices indirect heating. Internal organization electric boiler, consists of a heat-insulated container, inside of which there is a heating tubular element.
A design flaw, large heat losses due to indirect heating, as well as a long period of time required for the boiler to reach operating capacity. - Electrode boiler– has high energy efficiency. Compared to heating elements, efficiency reaches 40%. The heating principle is based on direct action on the coolant. The device uses two electrodes that create an electromagnetic field and cause the ions to move at a frequency of 50 vibrations per second. The coolant heats up almost instantly.
The disadvantage of electrode boilers is the inability to use the unit when connected to low temperature systems heating. The operation of an electric boiler requires the use of a special coolant with a high salt content. - Induction boilers– the operating principle is based on the use of alternating electric magnetic field. A copper core is installed inside the structure. When the electric boiler is turned on, vortex electromagnetic flows or Foucault currents are created. Under the influence of a magnetic field, the metal heats up and transfers heat to the passing coolant.
Induction boilers, like heating elements, belong to indirect heating equipment, but differ more long-term operation. Therefore, electric boilers based on a tubular heater are more economically profitable.
How to choose a garage heating electric boiler
In addition to the operating principle used, when choosing an electric boiler for heating a garage box, take into account the power of the device, as well as the manufacturer’s brand.It would not be superfluous to pay attention to the cost of the unit. New heating element boilers from well-known manufacturers will cost from 30 to 50 thousand rubles. Induction models will cost approximately the same amount. Electrode units - economy class boilers, are sold in the range of 10-15 thousand rubles.
Another selection criterion is the design of the electric boiler and the features of its operation. The most economical - electrode boilers, but their operation requires the use of a certain type of coolant and does not allow the use of antifreeze. Boilers cannot operate at low temperature heating. Therefore, electrode electric boilers are installed only for constantly heated rooms.
Induction heating equipment works with any type of coolant, therefore, it is installed in heating systems filled with non-freezing liquid. New heating elements maintain minimal heating of the coolant to prevent freezing of the heating system.
How to calculate power consumption
The optimal boiler power is calculated based on the area of the room. When calculating, take into account the necessary reserve of productivity in case of severe frosts.Calculation of heating a garage with an electric boiler is performed according to the formula 1 kW = 10 m². For a private garage of 20 m², you will need a 2 kW boiler. The required power reserve is 15-20%. The optimal solution would be to install a 3 kW electric boiler.
The best brands of garage electric boilers
Electric energy-saving heating boilers for garages are produced by domestic and foreign manufacturers. To narrow the search, equipment is classified into several categories, depending on the operating principle used:- Heating element boilers:
- Alvin EVP,
- Teplotech EVP,
- EVPM resource,
- EVAN EPO,
- Delsot EVP,
- Novel EVOS.
- Induction electric boilers: SAV PROF and SAV SPEC.
- Electrode options: Galan OCHA and Galan VULKAN.
Requirements for installing an electric boiler in a garage
Autonomous heating in the garage is carried out in accordance with the rules. When connecting, focus on technical features selected electric boiler.Installation of an electric heating boiler, up to 8 kW of power, in a garage is regarded as the installation of a conventional household water heating device. The connection is made through an RCD (except for an electrode heater) and automation. A grounding circuit is required. Electric boilers with a power of more than 8 kW require a three-phase voltage supply to the garage. Only a qualified specialist can connect the boiler to a 380V network. necessary clearance work.
A garage heating system with an electric boiler is effective for several reasons: low cost of installing heating equipment and completing the necessary documents, autonomous operation and high heating safety. Ease of use and quiet heating of the coolant are also noted as advantages.
Motorists often develop a special attitude towards the garage. They perceive it as a cozy place where they can do what they love - caring for their car, spend their free time there, and try to create the maximum possible comfortable conditions. Therefore, the arrangement heating system necessary not only to ensure acceptable storage conditions for the machine, but also for the convenience of its owner. Heating a garage should be inexpensive, efficient and safe. What system should I install? Every motorist does own choice. Let's consider which options are the most common, find out the reasons for their popularity, and analyze the advantages and disadvantages. The goal is to find the most economical heating, which will give the best result with minimal burden on the budget.
Comparison of heating sources with each other
If the building is located at a distance of no more than 20 m from the house, the problem is solved automatically - a system common to the house is installed. For garages located further away, autonomous systems are needed, and the following heat sources can be used: gas, electricity, solid fuel and used machine oil.
In large garages, installing heaters will not solve the heating problem; it makes sense to install a boiler and equip water system heating
Gas – cheap and efficient
The most economical heating of a garage is, of course, with gas, but it requires a connection to the central highway, paperwork, and permission from the competent authorities. Despite numerous advice on self-installation gas systems available on the network, we will not recommend installing gas systems yourself. Study gas systems Only specialists should. In addition, equipment can be installed only if the room meets all sanitary standards: there are ventilation ducts, the ceiling height is not lower than 2 m.
A more affordable and simpler heating method is the use of liquefied gas. Convectors are installed as heating devices, ceramic stoves, gas panels, heat guns, infrared heaters.
The main advantages of gas heating:
- efficiency;
- high efficiency;
- high degree of automation of systems;
- uninterrupted heating throughout the day.
Flaws:
- any, even the most reliable, gas equipment Potentially explosive, therefore failure to comply with safety regulations during design, installation and operation may result in serious damage;
- supplying main gas is not always possible and is associated with hassle and expense.
Do not ignore the danger and do not violate the rules and regulations governing the installation and connection of gas equipment!
If it is possible to connect to a gas main, the cheapest heating option would be to install water heating connected to a gas boiler
Electric heating
For most people, the option of installing an electric heating boiler disappears immediately, because more expensive heating cannot be imagined. But a portable electric heater for the garage is the choice of many motorists. It perfectly solves the problem of maintaining desired temperature, you can always choose a model of the required power, but there are also unpleasant nuances. It is difficult to call electrical equipment reliable. In addition, it is impossible to guarantee an uninterrupted supply of electricity, and access to it is not always available. They are used as heating devices.
Please note if you plan to install electrical equipment for heating, you need to take care that there are no combustible, lubricating, paint and varnish compounds and flammable materials in the room.
If installing a heating system with an electric boiler is impractical due to high costs, then a portable heater may well become a worthy alternative. Electricity costs are high in any case, but a mobile heater will be cheaper, and it does not require installation
Heating with solid fuel
Solid fuel allows you to create a completely autonomous heating system that does not depend on the availability of an electrical network or a gas main. You can install a stove in the garage or install heating with a solid fuel boiler. Firewood, coal, and sawdust are used as a heat source. This is economical, provides thermal comfort, and if you wish and have the necessary skills, you can make a stove with your own hands. Disadvantage: it is undesirable to store combustible and flammable materials indoors. Job heating device needs to be constantly monitored. The stove or boiler needs to be cleaned periodically.
If you have the materials, time and desire, a garage owner can make a homemade potbelly stove and save on heating installations
Processing – alternative fuel
For the thrifty owner, it’s simply a gift of fate, because the use of recycled materials allows you to reduce heating costs to a minimum. Approximate fuel consumption is 1 liter per hour. Before use, the oil must be cleaned in special heating units. You can assemble such an installation yourself. The only serious drawback of the stove during testing is that it can fail, since the fuel is of low quality and it is impossible to achieve uniformity of its composition.
The design of a furnace powered by recycled materials is simple. If desired, you can make both the oven and the oil purification system yourself
The best heating boilers
When the issue of choosing an energy carrier has been resolved, it is necessary to decide on the type of heating boiler. It must be economical, easy to use, and have high efficiency. Depending on the heat source, you can choose:
- Gas. Perfect option– condensing boiler equipped with automatic control. In addition to the cost of fuel itself, you can also save money due to the boiler’s ability to operate at low pressure. In the heat exchanger of the unit, water transitions from steam to liquid, which leads to the release of heat. Thanks to this operating principle, the boiler is 15% more economical gas models other types. You can also install a wall-mounted gas boiler, which provides power modulation.
- Solid fuel. It's best to buy. The operating principle of the unit is based on the effect of high temperatures on wood, as a result of which it decomposes into pyrolysis gas and dry residue. Gas is burned. To operate the boiler you need buffer capacity, it accumulates heat. Of all the solid fuel models, pyrolysis ones are the most economical, but there is a caveat: in the absence of wood, coal cannot be used for heating.
- Electrical. If you need to efficiently heat a room and prevent overloads in the electrical network, it is better to choose a boiler with six heaters and thyristor control. Thanks to the features of the device, you can limit power and save money; an additional plus is silent operation. There is only one minus, but it is significant: heating with electricity is always expensive, because... electricity is the most expensive source of heat.
The most cheap heating for a garage - a gas condensing boiler; other types of units may be more affordable and convenient, but they are all more expensive to operate
What is better for a permanent garage?
An insulated garage made of brick, concrete or shell rock is usually well insulated, so you can save money by equipping proper heating. Water systems are most often designed; air ones are used less frequently, but are also popular. If we compare these systems in terms of capital costs, then at first glance the air system seems cheaper, but operating costs are of fundamental importance, and from this point of view, the water system is better. Properly designed and high-quality installed water heating lasts much longer and is cheaper.
Arrangement of water heating
The initial stage is design. It is necessary to draw up a drawing on which all elements, the location of radiators, and turns will be marked. When installing the boiler, you must follow all the manufacturer’s recommendations noted in the instructions. For batteries, holders are attached using wall dowels, after which the radiators are hung at a height of 15 cm from the floor. The pipes are connected using fittings.
There are no particular difficulties in installing water heating; it can be done independently. If you don’t have the necessary skills, then it’s better to entrust this work to specialists. If you plan, be sure to invite a gas engineer; do not take risks by installing and connecting the equipment yourself.
Air heating systems
The operating principle of air heating is based on the creation of warm air flows that quickly warm up the room. If the system is mounted so that the air flows in the direction of the place where the machine is parked, it is possible to achieve effective removal moisture and prevent corrosion. Installing air heating equipment is less labor intensive than installing a water system. The main thing is to choose the right model thermal device required power. Most often, motorists choose fan heaters and thermal curtains for garages.
Infrared electric heaters
These devices are popular due to their ability to create local thermal comfort zones, ease of installation, economical energy consumption, no need to install smoke exhaust systems, etc. The devices do not dry out the air, operate silently, warm up objects and people, so the heat is not wasted. The air in a room heated by an infrared heater is heated indirectly by heated objects. When installing such a device, it should be remembered that prolonged direct exposure to radiation on paintwork is undesirable. The main disadvantage is still the same - the high cost of electricity.
Summary
The choice of heating system for a garage determines not only the temperature in the room, but also the durability of the car and the feeling of comfort for the owner. Cold and dampness in the garage are unacceptable, as they stimulate corrosion processes and negatively affect the condition of any equipment. Decide on the most accessible heat source, think about what system will be convenient - and get down to arranging a comfortable garage. Good luck!
Creating a comfortable temperature in the garage is an important task, the solution of which will keep the car safe during autumn-winter weather and renovation work at low temperatures. There are several types of heat generators used to heat a garage. The simplest among them is a potbelly stove for a small technical room. Brick ovens are built for car boxes of significant size.
Features of using a potbelly stove for heating a garage
When creating a heating system for a car box, a number of important factors should be taken into account:
- Install such heating installations is possible only in rooms where effective supply and exhaust ventilation is installed.
- The design of a potbelly stove for a garage must include safety elements that prevent sparks from reaching dangerous areas.
- There should be no flammable objects or building structures near the stove.
- A home-made garage stove must be reliable and durable. This can be achieved by using metal of the appropriate range, thickness and quality.
Main structural elements of a potbelly stove
The designs of potbelly stoves may differ from each other, but their main elements can be called the following:
- combustion chamber with lid;
- grate;
- chimney pipe;
- ash box.
You can buy a stove-stove for a car box, or you can make it yourself. It should be noted that making the unit yourself will allow you to save a decent amount.
The shape of a potbelly stove can be very different - rectangular, round or square. The design can be either framed or frameless. The body of frame furnaces is welded from steel profile, usually a corner, which is then sheathed with steel sheet.
Advice! To improve the operation of a homemade stove-stove for a garage, several holes are made in the lower part of the door. This measure provides additional air supply to the combustion space.
A round potbelly stove is made from a thick-walled pipe large diameter. To install it, a piece is cut off from the pipe and holes are made in it for the vent and chimney. A perforated oval-shaped metal sheet is laid between the ash pit and the firebox, performing the function of a grate. A cover is mounted on top of the stove body, and supports are welded on the bottom.
To make a chimney for a homemade garage stove, use a regular pipe.
Attention! To increase the efficiency of heat transfer processes, the pipe is given a curved and sometimes spiral shape.
To reduce fuel consumption, the outlet pipe is mounted above the loading door. In this case, the combustion products transfer part of the heat to the chamber walls before being discharged into the chimney. It is recommended to cover the body of such a stove with a quarter or half brick or cover it with a layer of adobe or adobe concrete.
Definition! Glinobit is thickly kneaded clay. Clay concrete is adobe with the addition of brick chips.
A furnace with such a casing has a higher heat capacity compared to a metal structure, and, therefore, a longer heat transfer period. The presence of a gap between the metal walls and the brick ensures the formation of convection air flows, and, consequently, increases the rate of heating of the room.
Brick oven for car box
Brick stoves operate on inexpensive and readily available fuel - coal, wood, briquettes, sawdust.
To make a brick garage stove with your own hands you will need:
- Materials – refractory brick, oven clay, finely sifted sand, cement, reinforcement, plastic wire, sandpaper, waterproofing compounds.
- Tools for laying bricks and jointing, as well as a shovel, angle grinder, file, level, plumb line, tape measure.
- Accessories – doors, canopies and latches for them, chimney valve.
The clay mortar for masonry is prepared in advance, the bricks are soaked immediately before starting work.
For garages, as a rule, stoves are made of simple masonry, without a grate. The last factor is a disadvantage because it makes cleaning the oven more difficult. The draft in this case is regulated by the size of the opening gap of the firebox door.
The base for a garage brick oven is thick sheet steel laid on a horizontally level floor surface.
Attention! If your goal is to build not only a functional, but also a decoratively attractive stove for the garage, then between the rows of bricks with outside it is recommended to lay wooden slats having the same thickness. As it hardens masonry mortar the slats are removed. This measure will allow you to get a neat jointing.
After laying the stove, you must wait completely dry bricks and mortar. Only after this can the stove be lit, checking the draft by burning a small amount of rags or paper in the firebox.
