Long-burning stoves for a wood-burning garage. Electric boiler for garage heating Diesel boiler for garage

How to organize garage heating with your own hands? What is the best way to heat a garage in winter? How to cheaply make a garage warm? Let's try to answer these questions later in the article and figure out which ones are better to use.

Garage heating options

The easiest way to heat the garage, which is located in the same building as a residential building or close to it. In this case, buildings are most advantageously heated by a common system. Most often this water system with gas boiler.

With a significant removal of the garage will have to heat it independently. When choosing a method, car owners most often take into account the type of fuel, cost, safety, complexity or ease of installation of heating equipment.

And so, how to make heating in the garage with your own hands? Do-it-yourself garage heating: cheap and fast (the most economical way) - is it real?

Gas heaters

Gas- one of the cheapest types of fuel, and the equipment needed to heat the garage can be easily found on the market.

Natural gas can be the basis for:

a full-fledged heating system with a gas boiler that heats the water that circulates in the pipes;
heating with a heat gun, in which the gas burns in a special burner, and the heat is distributed with the help of a fan;
using a catalytic or infrared gas heater, where the gas burns in ceramic honeycombs, and the heat spreads throughout the room.

For the first option it is necessary to connect to the main gas pipeline, which is carried out by employees of the gas service only after signing a number of documents and paying the cost of the tie-in.

This option for using gas is the most difficult: it takes time to prepare documents, design and install a heating system, purchase and install a boiler. The costs will pay off only with the constant heating of a large capital garage.

Second and third options are easier to use and do not require special permissions. For their implementation, you can use liquefied gas from cylinders.

According to the norms fire safety gas cylinder must be in a closed metal box, remote from heating element.

Of course, when using this type of heating, you will have to invest in special equipment, but the low cost of fuel will pay off these costs over time. The main disadvantage of using a gas heat gun and gas burners in that the products of combustion remain in the room and it must be ventilated frequently.

Furnaces for mining

This method is often used in car repair shops, but it is also suitable for a private garage. You can make a heater with your own hands from an oil tank (which can be a gas cylinder with a cut off top) and metal pipe about a meter long.

With the right design, it is safer than household gas stove, and the oil in it burns completely, leaving no soot and soot. In practice, such structures in need of cleansing from soot and soot at least once a week.

Another minus construction - the oil is ignited through the blower with the help of a torch and does not always light up the first time - it is unlikely that it will be possible to quickly kindle such a stove with chilled hands.

Oil used for heating must not contain combustible impurities: acetone, gasoline, etc., otherwise the tank will explode.

Based on the incineration furnace you can make a complete system with pipes and radiators. To do this, a boiler is placed on the furnace with an outlet for the water pipe and an inlet for the return, and pipes are placed in the room.

Heating with waste oil one of the safest(oil vapors burn in the pipe and ignition of objects surrounding the boiler is excluded) and economical methods (used waste product is used as fuel).

minus heating with used oil is the difficulty of installing the furnace - the length of the chimney should be about 4 m. and it is installed with a constant upward slope.

Boilers for solid and diesel fuel

A small one will do an excellent job of heating a small room and at the same time dry the air. You can burn it coal, firewood, peat briquettes, etc.

Instead of a homemade potbelly stove you can use a special boiler, but then the amount of its cost will be added to the cost estimate.

There are boilers for solid and diesel fuel. They are safe and do not require the constant presence of a person.

Some car owners install in garages brick ovens. The principle of operation of the stove is similar to that of a potbelly stove - when burned, the fuel heats the stove, from which the air in the room warms up. The difference between a brick stove and an iron stove is in the heating rate: the brick heats up longer, but it also retains heat better.

When installing a boiler or potbelly stove fire safety regulations must be taken into account: install the stove on a solid (preferably monolithic) non-combustible base, protect nearby surfaces from accidental ignition and properly equip the chimney.

Using a potbelly stove or brick oven is suitable for temporary garage heating- it is impossible to automate the supply of fuel, and it is inconvenient to constantly add firewood or coal. Another serious drawback of this option is the high fire hazard. Even with equipment around an iron apron, there is a risk of igniting fuel, rubber or other materials that are always in the garage.

Safe to use oven "Buleryan". They heat it with firewood, which is laid once every 5-10 hours. The disadvantage of such a stove is its cost, the complexity of arranging the chimney - it must be properly insulated, and the need for regular removal of soot.

General minus the use of the listed furnaces - the need to purchase fuel and equipment for storage space.

In addition, the factory boilers are expensive, and homemade potbelly stoves and brick ovens may cause a fire.

Circulating hot water system

Water heating - one of the most reliable and safe, but it is more suitable for large garages in which you need to maintain the temperature of several rooms.

For system device pipes are needed through which hot water will circulate, heating radiators that increase heat transfer and a boiler: gas, electric, for solid or liquid fuels. The complexity of the work and the cost of acquiring equipment will not pay off when used in a small room.

With electric boiler there are fewer problems, but you will have to regularly pay high electricity bills, and in the event of an accident on the power line, there is a possibility of water freezing in the system. The option is not suitable for regions with a predominance of strong winds and snowy winters: these phenomena can break the wires and, if you do not have time to drain the water from the system, you will have to change the burst pipes.

You can heat the water in the boiler, as mentioned above, on a stove that burns waste oil or on an ordinary potbelly stove. Such a system heats the room more slowly than heat gun or a convector, but also retains heat longer.

You can lower the freezing point of water by adding special liquids to it, the most common of which is antifreeze. Their use will slow down the formation of ice in the pipes, but in case of severe frost and a break in heating for more than a day or two, it is better to drain the water.

With frequent draining of water, iron pipes and radiators can rust. This can be avoided by using modern, metal-plastic equipment. For the same reason, it is undesirable to use old, previously used radiators - dust and rust can accumulate inside them, which will cause blockage of the system and disruption of water circulation.

Advantage systems with liquid circulating through pipes in uniform heating of the room and keeping heat for several hours after the end of heating.

Minus- in the complexity and price of the arrangement, the need to drain the water in the event of a heating cessation for several days.

Electricity

Heating with electricity is the ideal way to heat a garage without wasting time installing and installing the system. Today there is four options:

heat guns(most cheap option) - hot air flows out and spreads in all directions, thanks to the fan placed inside the device;
infrared heaters for a garage (the average cost method) they do not heat the air, but objects and surfaces, which in turn radiate heat. This method requires less electricity than a heat gun or convector. Infra-red rays are absolutely safe for humans, but can damage car paint. It is best if the rays are directed at the garage door - this will create thermal curtain and will allow you to warm the room more economically;
convector(more expensive than the first two options) heats up itself and spreads heat around itself. Heats the room more slowly than a cannon, but its heat remains a little longer after turning it off. On the market are various models convectors - equipped with wheels for movement, installed in one place or mounted on the wall;
inverter split systems(air conditioning systems are the most expensive way) allow you to maintain a constant temperature, save electricity, operate at temperatures up to -20 degrees. The main disadvantage is the high cost.

To use any electric heater, you must be sure of the quality of the garage wiring - it will endure significant loads. In addition, it is dangerous to leave these heaters unattended for a long time.

Disadvantages of heating with electricity is the high cost of equipment and consumed electricity, the possibility of a short circuit on an overloaded power line and dependence on the supply of electricity (if the wires break in the garage, it will not only be dark, but also cold).

Do-it-yourself garage heating: cheap and fast (the most economical way).

The choice of heating method depends on many factors.: the size of the garage, the type of building - permanent or temporary, you constantly need to maintain the temperature or you need to be able to quickly warm up the room, etc. Only by answering all the questions, the motorist will be able to do right choice because each method of heating has its advantages.

So a heat gun or a heater on wheels does not require installation, a potbelly stove device will cost the cheapest, you can save on fuel by heating the garage with used oil.

Wherein the safest options- these are factory boilers for heating with solid or diesel fuel, and a system with a liquid circulating through pipes, heated by a gas boiler, can provide a constant temperature.

The choice of a heating method for a garage space depends on the following factors:

length of stay of the owners in winter;
cost of equipment;
availability of energy carriers, price;
the convenience of use.

We propose to consider various options for resolving the issue and figure out how to make the most economical and efficient garage heating with your own hands.

The better to heat or the choice of energy carrier

In 99% of cases, centralized heating networks or main gas are not connected to garage buildings, so the owners have to choose autonomous heating methods. For heating the garage, you can use 4 groups of energy carriers:

various types of solid fuels - firewood, coal, briquettes, agricultural and other combustible waste;
diesel fuel, waste oil;
electricity;
liquefied gas in cylinders.

Advice. When you begin to choose the option of heating the garage in winter time, consider an important pattern: the more expensive the energy carrier, the easier and cheaper it is to organize heating that is easy to use. And vice versa, cheap or free fuel in the form of waste and garbage will bring a lot of trouble - labor costs and initial financial investments.

Combustion of solid fuel

Wood and various wastes are the cheapest fuel for heating, and in some cases it is obtained 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 screened from grain crops at the current. These are pieces of stems, weeds crushed by a combine, straw and other waste. The price of the energy carrier is very attractive and starts from 20 USD. e. for 1 ton.

After cleaning the grain, there is waste used for heating

If you decide to heat the garage with solid fuel in the winter, get ready to solve the following issues:

The win 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 with solid fuel will suit the owners of garages and boxes, staying there every day for 4-6 hours or more.

The use of mining and diesel fuel

Heat the box or garage with diesel fuel purchased at filling station, expensive and extremely unprofitable. Exceptional option - heating small area the premises where work is carried out, using a portable heater, whose characteristics are described.

Oil mining is a financially more economical energy source, although not the cheapest. This option can be considered seriously 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 gained particular popularity. They tend to shoot flames when the fuel contains a small amount of water or antifreeze, which causes a fire.

The advantages of using mining are high heat transfer, quick ignition and warming up of the garage box, ease of use (topping up oil is easier than chopping and carrying firewood). The conclusion is as follows: if fuel is inexpensive, or you spend a little time in the garage, then liquid fuel is 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 up to 2 kW. There are heaters and more powerful - 3 and 4 kW with a diesel consumption of 0.37 and 0.5 l / h, respectively. Price - within 330 USD. e.

Autonomous solar air heaters for cars

Electric 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 rate - it makes no sense to install a two-zone counter, you are not going to work in the garage at night.

We list all the advantages of electric heating:

There are only two minuses, but they are critical: the price of electricity and the limitation of the power consumption limit, which does not allow installing an efficient heat source. For example, if the number 3 kW is indicated in the contract with the management company, then a convector of only 2 kW is installed, which is not capable of heating the garage normally in winter.

For reference. Sometimes motorists use homemade "goats" and fan heaters in the boxes, despite the restriction. Why you can’t do this: there is a danger of fire in the wiring, the voltage drops at the neighbors, and if the employees check the power grids, you will face a large fine or a shutdown.

Electric heating is an option for a short stay in the garage. They came - turned on the heater - did the planned work in 1-2 hours - turned off the heating and left. If you turned the room into a workshop where you spend your working time, you will have to pay significant amounts for electricity consumption.

A standard wall convector heats the air in the room much more slowly than a fan heater

Gas heating

This method of heating the premises for car storage is acceptable for residents Russian Federation, where the retail price of liquefied natural gas is quite low. It will be too expensive for Ukrainians to heat garages with propane.

Autonomous heating from gas cylinders is as safe and comfortable as electric heating. Moreover, in Russia 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 block some of the positive from the ease of use.

Comparison of the cost of 1 kW of heat received from various energy carriers in the conditions of Russia and Ukraine has been published.

How to organize air heating

This method of heating involves direct heating of the air in the garage room from the selected heat source. This can be any of the following units:

solid fuel stove;
oven - dropper at work;
electric heater - convector, oil radiator or a 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, direct-acting heat guns and gas infrared heaters. Browse any automotive-related forum and see if users in the reviews complain about headaches and feeling unwell from inhaling exhaust gases.

Such heaters emit products of combustion of diesel fuel directly into the room.

Installation of a wood-burning stove and mining

Direct heating of the air in the garage by burning cheap fuel - firewood and a variety of waste - is the most economical way of heating. But it must be organized wisely, otherwise the heater will heat one corner of the room, and the opposite one will remain cold. It is clear that you cannot install the stove in the middle of the room, which means that the issue of heat distribution needs to be addressed differently.

To make effective air heating of a garage or a box with your own hands using a wood-burning stove, use our recommendations:

Order, buy or make an economical potbelly stove yourself, and not just an iron box with a pipe. You will find examples of furnaces with drawings, diagrams and assembly instructions.
The area of the heat exchange surface of the heater walls must correspond to the dimensions of the room. The calculation is as follows: in order to throw logs at intervals of 3-4 hours and evenly warm up a garage of 20 m², the heating surface area should be 1 m².
Convection fins are welded to the furnace body to increase the surface area and improve heat dissipation
The part of the body around the ash pan is not taken into account (it heats up slightly). On the other hand, the area of convective ribs welded to the walls from the outside is taken into account.
Install the potbelly stove in the chosen place and be sure to organize the airflow of the case with any fan - household, for hoods or a computer cooler. Due to the forced air movement, heat is more efficiently taken from the walls of the furnace and more evenly distributed over the box.
Options for blowing a wood stove with a fan
Lay the chimney horizontally along the wall before letting it out into the street, so it will give off more heat into the room.
Raise the chimney to a height of 5 m, counting from the grate, and provide it with a damper to adjust the draft. In the lower part, provide a condensate trap, adjust the cap at your discretion.
The horizontally laid chimney allows to increase the area of the heat exchange surface and improve the heating of the room

Note. The calculation of the area of the heat exchange surface of the stove is taken from the practical experience of our expert Vitaly Dashko. The calculation is correct for garages with a height of no more than 3 m.

There are designs of home-made 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 house, do not rush to throw it away. Take the old unit to the garage, connect it to the chimney and heat it with wood, forcing air into the empty water jacket using a cooler (from the side of the lower pipe). Then you don't have to cook.

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 catch fire. Do not use an ordinary two-chamber miracle heater - it is fire hazardous and consumes up to 2 liters of mining in 1 hour. Use models with a drip burner.

Placement of electric heaters

The first thing to do is to choose the right heating appliances for power. If you want to heat the entire garage space, 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 electric power), sufficient to maintain a positive air temperature.

Various heating methods can be combined. For example, it makes sense to hang an infrared panel above the workbench to provide local heating. Heat the rest of the garage with a stove or a heat gun - which is more profitable. Do not forget about - it is necessary when burning any type of fuel.

Water heating system

You need to understand that installing water heating makes sense when you are in the garage all the time. Otherwise, the costs will not justify themselves, because in addition to the 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 highway;
non-freezing coolant - antifreeze.

For reference. The garage room 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 the previous section), or determine the length of the pipes of the self-made register according to the table:

In the table, t1 means the temperature of the coolant, t2 - the air in the room

The calculation procedure is as follows. We take a steel pipe DN 80 (Ø89 mm) and find out from the table that 1 m of length is enough to heat an area of 1.37 m². We take the quadrature of the garage, for example, 20 m² and divide by this figure: 20 / 1.37 \u003d 14.6 m - the total length of the heating part. We distribute it to 2-3 heaters and cook the registers according to the drawing.

Take the circulation pump of the lowest pressure (4 m of water column), expansion tank - of the minimum volume. Pipes - polypropylene, steel or metal-plastic in size DN 15. Then install radiators on 2 opposite walls and assemble a simple two-pipe closed-type heating system connected to a heat source according to the scheme:

Advice. Do not forget to add a filter to the circuit - a sump and ball valves to cut off the heat source and drain water from the system. At the top point, put an automatic air vent, and on the batteries - Mayevsky cranes for air release.

Why do we not recommend making an open type system in the garage, 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 in the search phrase "garage heating" and look at the pictures on English-language sites, then you will not find any wood-burning and oil stoves in Western European garages. What are the local motorists basking in:

We have already considered the first 2 options above. The third method is also far from new: the 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 the summer (chilled water is sent to the radiator instead of heated water).

Heater made from a car radiator

One minus is the increased cost of equipment, because the coolant needs to be heated in the boiler and fed 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 similar heating by installing a home-made analogue of a heater made from a car radiator and any suitable fan. How it is implemented, look at the video:

From the foregoing, as well as on the basis of practical observations, the following conclusions arise:

Despite all the difficulties with burning solid fuels, firewood and other wastes occupy a leading position among energy carriers due to their affordable price.
For the same reason, air heating is installed in most garages. It is simple in execution and allows you to quickly warm up the room.
Efficiency of air heating is given 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 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 box with slots in the gate porches absolutely does not keep heat and cannot be heated, so it is expensive and pointless to heat it. Another thing is the walls made of foam blocks or insulated from the outside with foam, the savings in heating such a garage are quite achievable.

Warming the garage building from the inside and outside increases the level of its comfort many times over. But even such operations are not able to make the building really warm during winter frosts, so you should think about choosing a rational heating system for a motorhome.

An excellent option will be different models garage boiler, but how to make the right choice among a wide range of manufacturers? We'll talk about this in more detail later.

In winter, the air temperature drops below zero, so it’s unpleasant to be inside a garage building without a boiler room. Heating appliances today are manufactured in a wide variety. They differ in their cost, size, power source, which largely determines the operational parameters of such equipment.

Today we will consider the following models of boilers that are worth choosing:

gas unit;
electric boiler for garage;
on solid fuel: firewood, coal, construction debris, etc. heaters;
heater for garage alternative fuel: used engine oil, pallets, biofuels, etc.

Gas cheap and efficient

Gas is the most economical fuel, provided that the main pipe is located close. Otherwise, you will have to use gas cylinders, which is not always convenient, cheap, practical. The installation of such equipment does not have to be supplemented with the installation of a water heating system for wall surfaces and floors.

You can pick up a gas boiler for heating the garage, supplemented by a built-in fan. This design of the device allows you to evenly distribute heated air over the entire area of the room, as a result, it warms up faster, eliminates the risk of mold and fungus in the corners of the room.

We describe the main advantages of boiler gas equipment:

significant savings on the purchase of energy resources;
availability of gas provided that the main gas pipeline is located nearby;
autonomy of work processes, no need to constantly monitor the device;
high rates of energy efficiency;
long service life, rare breakdowns;
the ability to use liquefied gas cylinders or connect to the main gas pipeline;

Gas boiler device.

The disadvantages of gas heating equipment are the following points:

installation of a gas boiler is carried out only with permission from the supervisory authorities;
when installing equipment, it will be necessary to allocate a separate room, carry out a series of actions, the purpose of which is to increase the fire resistance of wall and floor surfaces: this will eliminate fire cases;
the need for material costs to equip a high-quality ventilation system.

On a note! The operation of do-it-yourself boilers should begin with a test run. Installing such equipment yourself is not difficult, but it must be installed in accordance with all norms and rules, which will eliminate the risk of interruptions.

Electric heating

It is advisable to purchase an electric boiler for heating a motorhome in the absence of main gas. It is very convenient to use it, but installation inside a small building will be quite expensive. If the climate is mild, it is better to prefer an electric convector, a fan heater, additionally equipped with a thermostat.

The advantages of electric boilers for garage heating are described below:

no noise during the operation of the garage electric boiler;
it is not difficult to equip a garage with your own hands to equip heating with the help of electrical equipment;
full automation of work processes: when a certain air temperature is reached, the unit turns off for a short time, and then independently starts functioning in the previous mode;
high safety performance: if the unit overheats, the fuses will stop the system;
a home-made electric boiler functions without combustion products, it is economical: installation will be cheaper, since there is no need to buy chimney pipes;
equipment is different compact size, making it easier to plan for a small motorhome.

Electric boiler connection diagram.

Tenovy electric boiler has the following disadvantages:

Although the consumption of electricity is quite low, but it itself has a high cost today;
The functioning of the heating system is completely dependent on the availability of electricity: during power outages, the garage room can become cold;
The installation of the unit must be accompanied by the installation of additional wiring: if the equipment is of high power, a three-phase network will be required.

Heating with solid fuel

The fuel of electric boilers for garage heating can be hard materials: firewood, coal, peat, straw, construction debris. They are refueled inside the equipment at intervals of 2 to 14 days, which is quite convenient.

It is optimal to heat a garage with a solid fuel heating boiler when it is not possible to connect to the main gas pipeline, there is no desire to use gas cylinders. Similar models are also selected if the installation of an electric boiler is not possible for certain reasons.

We describe the main advantages of boilers for wood, coal and other solid materials:

high profitability;
a wide range of fuel types, its low cost;

Diagram of a solid fuel boiler.

The disadvantages of solid fuel equipment are the following points:

the owner of the garage must control it almost all the time the heating system is in operation so that there are no interruptions in operation or complete combustion of the fuel;
the installation of a solid fuel boiler must be accompanied by the arrangement of a high-quality ventilation system, a chimney.

Mining: alternative fuel

A garage heating system can be powered by alternative fuels. One of the advanced technologies is the use of used engine oil. No less relevant in rural areas today are models that run on biofuel, pallets made by the hands of farmers.

Let's give a brief description alternative species fuel for the garage heating system.

On a note! You can make a liquid fuel boiler with your own hands. The thermotechnical part of the installation is extremely simple to perform, and you can find a working diagram on the Internet on numerous forums for car owners.

The best heating boilers

If a decision is made to choose a high-quality boiler for the garage, it is worth studying the offer of manufacturers, to understand which models are more popular than others. Then you can be sure of the quality of the model chosen. How to choose which criteria to take into account?

Criteria optimal choice heating systems:

price;
productivity;
safety;
installation features.

Heating the garage with a boiler.

Based on these criteria, we will describe the main brands of electric boilers for the garage, which are in high demand in the domestic market and are worth the attention of the consumer:

Baxi.
An Italian brand, known to customers around the world, but it is most popular in Europe. Baxi models are distinguished by convenient adjustment, high efficiency, can work offline, and are capable of self-diagnosis. Boilers Baxi equipped with energy efficient pumps that provide high efficiency. There are models that can be installed outdoors, but are not cheap.
Vaillant.
The brand manufactures boilers with high performance, reliability due to the improved design of the burners, the use circulation pumps, creating a case from high-quality steel alloys. Vaillant do not overheat, do not jam. But big sizes allow you to place such a boiler only in a large garage.
Protherm is a manufacturer of high quality boilers of various capacities.
Variants of small dimensions are silent, interesting design, often installed in motorhomes.
It is also worth noting the products of the Ferroli and Bosch brands, which also earned the recognition of a large number of car owners.

On a note! Not always an expensive boiler is associated with the word "good". But often best models boilers are still made by well-known companies and are not cheap.

Outcome

A high-quality electric boiler for heating allows you to create optimal conditions inside the motorhome, turn it into a comfortable room for staying even in severe frosts outside.

Heating with electricity will not cost too much if you choose the right heating system and insulate the garage. Even the most economical electric garage heating boiler will “warm the street” if the walls, gates and roof are not insulated.

On the one hand, sudden temperature changes in winter accelerate metal corrosion. But, if you organize good ventilation in the garage, then warming up the engine is not required in a warm room, and there are no cold starts that are detrimental to the engine.

If it is possible to organize, with a central gas supply, then other options are not needed - this is the most economical and convenient option, but, unfortunately, it is not available to everyone.

According to the initial costs, the installation of water heating from a central gas boiler is an expensive undertaking. Requires underground laying and insulation of pipes, installation of radiators and a device for piping indoors.

Advice. Metal-plastic pipes are much more profitable and practical than metal ones. Installation of metal-plastic does not take much time and costs less than welding.

Garage heating with underfloor heating is an economical and convenient option, with central water gas heating. Radiators and pipes take up a lot of space, get dirty quickly, give a high heat consumption and there is no way to place convenient shelves for tools.

Metal-plastic pipes with a heat carrier are mounted directly in concrete screed and evenly heat the entire room. Therefore, the entire heating system is reliably protected from mechanical damage and warms up the car from below.

Boiler for wood or diesel

To date, the cost of firewood, coal and even spent diesel fuel has increased significantly. And it is no longer possible to argue that it is more economical to use wood-fired heating than electric heating in many regions.

To heat 1 m3 of water to 50°C on an electrician, the costs will be approximately 135 rubles, on diesel fuel the same heating will cost 170 rubles. Therefore, now diesel boilers and even waste fuel boilers are becoming unprofitable.

For all solid fuel boilers, it is necessary to install a chimney, which also entails additional costs. According to fire safety rules for heating equipment, the height of the pipe should be twice as high as the height of the building.

Solid fuel pyrolysis boilers of long burning

Relatively new types of heating, requiring the loading of fuel briquettes every two days. But the boiler itself is expensive and the fuel for it is also expensive. If you calculate the payback, then in ten years this option will pay for itself.

Therefore, for a garage it is better to stay on electric heating - clean, convenient and, thanks to modern automation, inexpensive.

Gas autonomous heaters

It is not recommended to use gas cylinders in the garage as heating equipment, even if all safety measures are observed. If you decide to choose this heating option, then choose a heater with a closed combustion chamber and ceramic elements. Additional automatic switching on and off will save fuel consumption.

Electric garage heating

It is not difficult to calculate the energy consumption for heating a garage. The consumption will not depend on the power of the appliance. Therefore, when choosing an electric heating option, we do not focus on power and consumption, but choose the most convenient for installation and technical specifications electric boiler or heater.

Why does the power of the device not affect the consumption of kilowatts? If, on average, consumption - 100 watts is needed for square meter, so there is no difference in the power of the device. For example, we put a heater with a consumption of 1 kW / h and it warms up the premises in two hours. If we put a device with a power of 2 kW, then it will heat the garage faster - in an hour, but the power consumption is the same - two kW.

Estimated energy consumption for heating middle lane Russia - 100 watts per 1 square meter.

Which electric garage heating option to choose

Which type of heating equipment is more profitable? Consider the advantages and disadvantages of the proposed electric garage heating systems.

Stationary electric boiler and water heating

Types of electric boilers that can be installed in the garage:

boiler on electrodes - inside the thermally insulated heating tank there are two electrodes that instantly heat the carrier due to the generated electromagnetic field. Therefore, the efficiency and speed of heating will be maximum. The disadvantage is that a special coolant is required - a saline solution;
induction boilers - the copper core inside the tank is heated by an alternating electromagnetic field created by Foucault currents (vortex electromagnetic flows). According to the characteristics, such boilers are not much more economical than heaters on Tenah, but twice as expensive.

For the price, a good heating and induction boiler costs about 40 - 50 thousand rubles, a home-made one will cost three thousand. Electrode boilers of the economy option cost from 10 to 15 thousand rubles.

Since 1 kW of electricity heats 10 m2, then for a garage of 20 squares you need to take an electric boiler of 3 kW, since you need a power reserve.

According to reviews best boilers on heating elements - Teplotech, Evan EPO, Novel and Alvin EVP. Of the induction boilers, the brands SAV SPEC and SAV PROF are trusted. The best options for boilers on electrodes are the Galan company (Ochag and Volcano).

In addition to the boiler, it is also necessary to install piping in the garage. Therefore, experts recommend a floor heating device, rather than radiators, for reliability and heat savings.

Underfloor heating in the garage

Installation of a water heated floor - in stages:

on the subfloor we lay a layer of waterproofing (polyethylene film or roofing material;
pour the screed using a concrete mixture with heat-insulating additives;
we lay a foil insulation on the screed, the thickness of the insulation is small, 1 cm;
we do the insulation mesh reinforced a layer of cement screed;
We mount the water circuit directly to the reinforcing mesh with clamps. It is fashionable to lay pipes in a spiral or snake. The maximum length of the entire circuit is no more than 70 meters.

Now it remains to fill the finishing layer of the floor concrete mix with hardening additives that protect the floor from temperature extremes and heavy vehicle weight.

Single-circuit or double-circuit electric boiler

If you plan to use the garage as a workshop, then it is better to stay at a more expensive, but also more reliable option electric boiler - double-circuit. In this case, the room will be constantly provided with hot water.

Let's compare the advantages and disadvantages of the two systems:

one heating circuit requires less electricity (thirty percent less consumption than double-circuit equipment);
if you additionally install a boiler in one circuit, then it will cost more in terms of electricity consumption than a two-circuit system;
the cost of equipment for two heating circuits is 40 percent higher;
in terms of durability, 1 circuit is seven years more reliable than 2 circuits, since complex equipment breaks more often.

Disadvantages of an electric boiler with a water circuit

This version of the heating system has a number of serious drawbacks that must be taken into account:

at severe frosts and an emergency shutdown of electricians, the water in the pipes can freeze, so it is additionally necessary to install a diesel generator with automatic switching to emergency operation. It's not cheap. As an option - a device for a water-heated floor with insulation, which will keep the coolant from freezing, but not longer than 12 hours;
have to spend on metal-plastic pipes and accessories, a pump for forced circulation of water in the system;
annually it is necessary to flush the pipes and change the coolant.

Compared to simpler and inexpensive options an electric boiler and a water circuit are not the best solution.

Heat guns also consume too much energy, as can be seen from the table.

Convectors

Heating a garage with a convector is simple, convenient and economical. Now on sale is a large selection of equipment with automation, which can be set not only to a certain temperature for heating the room, but also by day of the week and by hours of operation.

Expensive models of convectors are additionally equipped with air ionization functions and are protected from freezing in the most severe frosts.

There are floor and wall type convectors. Devices that are mounted on the wall can be moved, and floor convectors, although they warm up the air faster, are mounted permanently. The heat source can be installed anywhere, as needed.

Infrared heaters

The most economical and simple option, which does not allow the motor to freeze. Infrared rays heat only the area to which they are directed, so it will not be possible to achieve heating of the entire room.

But, if you place an IFC lamp on the ceiling above the hood, then a 50 W model will be enough to keep the engine from freezing, and a 100 W model will quickly and directionally heat the air up to 20 degrees.

Analyzing all heating systems from electricity, we can conclude that the most convenient and profitable is a convector. No need to spend money on installation of communications and maintenance of the water circuit. It is better to spend money on good automation, which will reduce energy consumption.

Garage heating boiler: how to choose

5 (100%) votes: 3

Now we will try to decide which boiler to choose in the garage, i.e. what will he have as a “fuel”: gas, electricity, firewood or diesel / mining.

Many motorists, and in particular the representatives of the stronger sex, have a special attitude towards the garage. Often in this room they spend a significant part of their free time, because this is the place where you can do the maintenance of your car. Therefore, of course, it should be as comfortable as possible, and the arrangement of the garage heating system should be approached with caution. In addition, the abundance of heating boilers for this kind of premises allows each owner to choose the appropriate option.

Consider the most popular methods of garage heating, characterize the criteria for choosing units and analyze their disadvantages and advantages.

Warm garage in the house

Garage heating options

Which way to choose for garage heating - each owner decides for himself. Many factors influence the choice, but the key ones are the following:

type of fuel used;
ease of operation of the system;
safety;
price.

The location of the garage also plays a significant role in this situation. If the building is located at a close distance from the house (no more than 20 m), then it will be most convenient to equip a system common with the living space. If the garage is located at a distance, then it is necessary to use an autonomous heating system.

Water heating is one of the ways to heat the garage, which is characterized by reliability and safety. This type of heating is suitable for large rooms, because the complex work process and the money spent on the purchase of equipment will not pay off if used in small garages.

For the installation of the system, pipes are needed through which the circulation process will be carried out hot water, heating radiators that increase heat transfer and directly one of the types of boilers: gas, electric, for solid or liquid fuels.

Heat sources can be:

solid fuel;
electricity;
used oil.

Garage heating scheme

Boiler for wood and other solid fuels

The option of heating a garage with solid fuels (, firewood,) is very popular, since these heat sources are often more profitable and economical than gas or electricity.

If you want to establish garage heating in the simplest and cheapest way, then installing a potbelly stove (small stove) would be the best option. It does not require a gas supply to operate. electrical network. Despite the fact that this method is less expensive, it is rather inconvenient, because it is necessary to constantly add firewood or coal, and this takes time. A solid fuel potbelly stove is well suited for small-sized rooms; in a spacious garage, its use will be ineffective.

The potbelly stove should be installed at the maximum distance from combustible materials and wood coatings in order to avoid accidental ignition.

The Buleryan oven is safer and more convenient to use. It is heated with firewood, which needs to be laid every 7-10 hours, but Buleryan is an expensive pleasure and not everyone can afford it.

When purchasing a solid fuel boiler, it is imperative to follow the rules for its operation:

To kindle a fire, you need to arm yourself with paper or special spacers.
It is necessary to equip a well-insulated chimney and periodically clean it.
It is necessary to install a solid-state heating boiler exclusively on a monolithic base.
Surfaces near the boiler must be protected to prevent ignition.

When operating, do not forget that heat transfer from various kinds solid fuel is different, it can vary significantly even for wood of different species.

Thus, we can note the general advantages for solid fuel boilers for the garage:

fuel availability;
profitability;
high efficiency.

In modern solid fuel boilers, the efficiency reaches 70%.

Flaws:

high initial equipment costs;
accident rate.

Solid fuel boilers for the garage are produced by both domestic companies: Zota, Teplodar, and European concerns: Buderus, Viessmann, Froling.

You also need to pay attention to the boilers long burning to be able to increase the battery life of the garage heating system.

Boilers diesel and waste oil

Most often, garage owners prefer a garage. This is due to the low cost of diesel fuel; on the heating equipment market, you can easily and quickly select and purchase best option boiler with suitable technical and operational parameters.

The main disadvantage of diesel garage heating is that you will have to install a container in which liquid fuel will be stored.

good option the heating boiler for the garage is the use of waste oil as fuel. Therefore, often used by the owner of garages for their heating.

Typically, furnaces that work on mining are red hot, so storing flammable items near them is strictly prohibited.

If it is not possible to purchase a liquid fuel boiler, then home-made heaters can act as heating devices that heat the air in the garage, and the combustion products are brought out.

Gas boiler

WITH gas boilers the situation is much simpler than with solid fuel. First, they do not need to be so strictly controlled. Secondly, the variety of devices on the market and a wide range of prices.

You can use gas as a fuel for heating a garage in the following ways:

A complete heating system with a gas boiler that heats the water circulating in the pipes. With this option, you need the gas service employees to connect your heating system to the main gas pipeline, for this you need to sign a number of documents and pay the cost of the tie-in.
Using a hot air boiler: heating is carried out by a heat gun. With this method, the gas burns in a special burner, and the process of heat distribution occurs through a fan.

The most economical option is condensing boilers. Their efficiency is 10% higher than conventional gas ones.

The first option is the most difficult: it will take time to collect and prepare all the necessary documents, design and install a heating system, and also need to buy and install a boiler.

The second method does not require special permits; in this case, you can use liquefied gas from a cylinder.

According to fire safety rules, the gas cylinder must be located in a closed metal cabinet, at a remote distance from the heating element.

When using such a heating method as a gas boiler, positive points can be noted:

availability of equipment on the market;
low cost of fuel;
high efficiency;
saving your time.

Be sure to place a fire extinguisher and other means of extinguishing fires in the garage.

The main disadvantage of operating a heat gun is the constant need to ventilate the garage, because. combustion products remain in the room.

The Russian gas boiler equipment market has its own leaders in terms of quality and reliability:

electric boiler for garage

Electric heating - best way heat the garage, saving time on installation and installation of the system. Today, the heating equipment market offers a wide range of different electric heaters. Each user can use any method of heating: electric boiler, heat gun, inverter split system.

This type of heating has many advantages, including:

wide possibilities for automation;
low initial costs;
no need to install a chimney;
small sizes;
minimal human participation in the operation of the boiler;
no fuel combustion.

However, along with many obvious good points electric boilers, one cannot fail to mention some of the shortcomings, such as, for example:

high cost of electricity;
difficulty in creating a high-power heating system;
possible lack of electricity.

To use any electric heater, it is important to ensure the quality of the garage wiring, as it will be heavily stressed. In addition, it is dangerous to leave these heaters unattended for a long time.

The best brands of garage electric boilers:

Heating boilers - Alvin EVP, Teplotech EVP, Resurs EVPM, EVAN EPO, Delsot EVP, Novel EVOS.
Induction electric boilers - SAV PROF and SAV SPEC.
Electrode variants - Galan OCHAG and Galan VOLCANO.

Thus, from the foregoing, it follows that it is much easier with an electric boiler, but there is one significant disadvantage - you will have to constantly pay high electricity bills, and in the event of an accident on the power line, the water in the system may freeze.

Summing up, it should be noted that the choice of a garage heating system should be approached with all responsibility, because not only the temperature and comfort in the room, but also the durability of your car depend on it. Cold and dampness in the garage are unacceptable, as they contribute to rusting and most negatively affect the condition of the equipment.

Therefore, weigh the pros and cons, decide which garage heating system is right for you and start arranging your room.
