Economical heating of the garage with your own hands: how to reduce heat loss and the better to heat. Wall-mounted electric boiler for a garage - calculation, choice Diesel boiler for a garage
Given the simple installation and the minimum number of permits, an electric garage boiler is the optimal heating solution. When choosing, pay attention to the principle of operation, the requirements associated with the installation, the required power.
Types of electric boilers installed in garages
In order to choose the right electric boiler for the garage, you need to understand the principle of operation used and the associated limitations during operation. There are three types of boilers that differ in their internal structure and the principle of heating the coolant:- TENovye boilers - refer to heating devices indirect heating. Internal organization electric boiler, consists of a heat-insulated container, inside which a heating tubular element is located.
Lack of design, large heat losses due to indirect heating, as well as a long period of time required for the boiler to reach operating power. - Electrode boiler- has high energy efficiency. Compared with heating elements, the efficiency reaches 40%. The principle of heating is based on a direct effect on the coolant. The device uses two electrodes that create an electromagnetic field and cause the ions to move at a frequency of 50 oscillations per second. The coolant heats up almost instantly.
The lack of electrode boilers, 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 principle of operation is based on the use of alternating electrical magnetic field. Inside the structure, a copper core is installed. When the electric boiler is turned on, eddy 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 they differ in longer operation. Therefore, it is economically more profitable than electric boilers based on a tubular heater.
How to choose a garage heating electric boiler
In addition to the principle of operation used, when choosing an electric boiler for heating a garage box, the power of the device, as well as the brand of the manufacturer, are taken into account.It will not be superfluous to pay attention to the cost of the unit. Heating elements of well-known manufacturers will cost from 30 to 50 thousand rubles. Approximately the same amount will cost induction models. Electrode units - economy class boilers, are sold in the range of 10-15 thousand rubles.
Another selection criterion is the device of the electric boiler and the features of its operation. The most economical are electrode boilers, but their operation requires the use of certain type coolant and does not allow the use of antifreeze. Boilers cannot work with 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. Heating elements maintain a minimum heating of the coolant to prevent freezing of the heating system.
How to calculate power consumption
The optimal power of the boiler is calculated according to the area of \u200b\u200bthe room. When calculating, take into account the necessary margin of performance, in case of severe frosts.The 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, a 2 kW boiler is required. The required power reserve is 15-20%. The optimal solution will install a 3 kw electric boiler.
The best brands of garage electric boilers
Electric energy-saving heating boilers for the garage are produced by domestic and foreign manufacturers. To narrow the search, equipment is classified into several categories, depending on the principle of operation used:- TENovye boilers:
- Alvin EVP,
- Teplotech EVP,
- EVPM resource,
- EVAN EPO,
- Delsot EVP,
- Novel EVOS.
- Induction electric boilers: SAV PROF and SAV SPEC.
- Electrode options: Galan OCHAG and Galan VOLCANO.
Requirements for installing an electric boiler in a car garage
Autonomous heating in the garage, carried out in accordance with the rules,. When connecting, focus on technical features selected electric boiler.The installation of an electric heating boiler, up to 8 kW power, in a garage is regarded as the installation of a conventional domestic water heater. The connection is made through the RCD (except for the electrode heater) and automation. A ground loop is required. Electric boilers with a power of more than 8 kW require a three-phase voltage branch to be connected to the garage. Only a specialist with the necessary work permit can connect the boiler to the 380V network.
A garage heating system with an electric boiler is effective for several reasons: low installation cost heating equipment and design required documents, autonomous operation and high heating safety. As pluses, they also highlight ease of use and noiselessness of heating the coolant.
Creation comfortable temperature in the garage is an important task, the solution of which will allow you to keep the car safe during the autumn-winter bad weather and carry out repair work at low temperatures. There are several types of heat generators used for garage heating. The simplest among them is a potbelly stove for a small technical room. For a car box of considerable size, brick ovens are built.
Features of using a potbelly stove for heating a garage
While creating heating system car boxing should take into account a number of important factors:
- It is possible to install such heating installations only in rooms in which effective supply and exhaust ventilation is arranged.
- The design of a potbelly stove for a garage must provide for safety elements that prevent sparks from entering dangerous areas.
- Flammable objects and building structures should not be located near the potbelly stove.
- A do-it-yourself garage oven must be reliable and durable. This can be achieved by using metal of the appropriate assortment, thickness and quality.
The main structural elements of the potbelly stove
The designs of potbelly stoves may differ from each other, but their main elements can be called the following:
- combustion chamber with cover;
- grate;
- chimney;
- ash box.
You can buy a potbelly stove for a car box, or you can make it yourself. It should be noted that the manufacture of the unit with your own hands will make it possible to save a decent amount.
The shape of the potbelly stove can be very different - rectangular, round or square. Execution can be both frame and frameless. The body of frame ovens is welded from a steel profile, usually a corner, which is then sheathed with a steel sheet.
Advice! To improve performance homemade stove- potbelly stoves for the garage make several holes in the lower part of the door. This measure provides additional air supply to the furnace space.
potbelly stove round section made of thick-walled pipes of large diameter. For its device, a piece is cut off from the pipe and holes are made in it - for the blower and the chimney. Between the blower and the firebox, an oval-shaped perforated metal sheet is laid, which acts as 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 oven, use an ordinary pipe.
Attention! To increase the efficiency of heat exchange 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 products of combustion, before being discharged into the chimney, part of the heat is given off to the walls of the chamber. The body of such a furnace is recommended to be lined with a quarter or half a brick or covered with a layer of clay or clay concrete.
Definition! Glinobit - densely mixed clay. Clay concrete is clay with the addition of brick chips.
A furnace with such a casing has a higher heat capacity compared to a metal structure, and, consequently, a longer heat transfer period. The presence of a gap between the metal walls and the brick provides the formation of convection air flows, and, consequently, increases the rate of heating the room.
Brick oven for car boxing
Brick ovens run on inexpensive and quite affordable fuel - coal, wood, briquettes, sawdust.
To make a brick garage oven with your own hands, you will need:
- Materials - refractory bricks, oven clay, fine-grained sifted sand, cement, fittings, plastic wire, sandpaper, waterproofing compounds.
- Tools for laying bricks and grouting, as well as a shovel, angle grinder, file, level, plumb line, tape measure.
- Accessories - doors, canopies and latches for them, a chimney valve.
The clay mortar for masonry is prepared in advance, the bricks are soaked immediately before starting work.
For a garage, as a rule, simple masonry stoves are made, without a grate. The latter factor is a disadvantage, since it complicates the cleaning of the oven. The draft in this case is regulated by the size of the opening gap of the firebox door.
base for garage brick oven is a thick sheet steel laid on a horizontally leveled floor surface.
Attention! If your goal is to build not only a functional, but also a decoratively attractive garage oven, then it is recommended to lay between the rows of bricks from the outside wooden slats having the same thickness. As the masonry mortar hardens, the slats are removed. Such a measure will allow you to get a neat stitching.
After laying the furnace, it is necessary to wait for the bricks and mortar to dry completely. Only after that, the furnace can be kindled, checking the draft by burning in the furnace a small amount rags or papers.
Other types of garage ovens
In addition to the listed types of heating units, for heating garages use:
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;
- Ease of use.
We propose to consider various options problem solving and figure out how to make the most economical and efficient heating DIY garage.
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
Heating a box or garage with diesel fuel purchased at a gas station is expensive and extremely unprofitable. An exceptional option is to heat a small area of \u200b\u200bthe room 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 cheap 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 in an agreement with management company the figure is 3 kW, 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 a 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 working time, then 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 retail price liquefied gas low enough. 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 cooler 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. 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 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.
laid horizontally chimney allows you 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 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 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 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 the phrase "garage heating" in the search 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 premises.
The advantages of this option are compactness, heating speed and the possibility of air conditioning in summer period(chilled water is sent to the radiator instead of heated).
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.
Most car enthusiasts use the garage not only for its intended purpose, but also as a place where you can take a break from household chores, do a hobby or do some household chores. In order to stay comfortable in the garage even in winter, the room must be somehow heated.
For heating to be economical, you need to know the features existing methods heating, since you can choose the best one for yourself only taking into account specific situation and a number of factors: the dimensions of the room, its remoteness from housing, the availability of consumed fuel, the budget for providing the garage with heat, etc.
Heating Options for a Standard Single Car Garage
The most popular and most economical way is to heat the garage with electricity, especially if the building is located at some distance from the house, has small dimensions and is not visited often in winter.
There are several ways to heat a garage space using electricity.
Convector
Models of electric convectors for use in garages and other premises technical purpose
Reliable and efficient device, the principle of operation of which is based on air convection initiated by heating elements - cold air enters the device from below and, heating up on contact with the heating element, rises warm to the top.
Convectors are available in floor, wall or universal versions - on support legs, with brackets for wall mounting or equipped with both mounting options. The latter variety 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:
- fast 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 the air environment cools by 1 degree;
- safe operation and ease of maintenance;
- durability;
- Possibility of use in rooms high humidity and pollution, since the operating elements of the device are closed by a protective case.
Disadvantages of the convector:
- higher cost compared to some other types of electric heaters (quartz);
- the achievement of the effect of the work of the convector in the garage occurs after at least half an hour of time;
Portable fan heater of high power floor version for household and industrial needs Principle of operation: a heat exchanger (heating elements or a spiral) is heated by means of electricity, the air from the room is blown into the heater by a fan, passed between the heating elements and returned to the garage already hot.
Advantages of a fan heater:
- environmental friendliness - the absence of any emissions into the surrounding space during work;
- convenience of adjusting the intensity of heating - there are switches for heating modes (turning off part of the heating elements) and fan speed;
- small dimensions and mobility - can be installed anywhere in the garage;
- the possibility of focused heating of zones or objects;
- rapid heating of the room;
- device equipment automatic shutdown overheating or overturning;
- the possibility of additional self-completion with an electromechanical thermostat for automatically maintaining the set temperature in the room;
- low cost of electrical appliances of small and medium power;
- ease of use and maintenance.
Like any unit The fan heater also has disadvantages. which must be taken into account:
- heating-related decrease in air humidity in the room;
- the presence of a dust accumulation factor on the heating elements, fraught with fire or, at least, bad smell in the garage;
- noise caused by the operation of the fan;
- increased electricity consumption.
Despite these shortcomings, the use of a fan heater is the most popular heating for a garage.
Lightweight Timberk heat gun with handle for easy portability A compact and easy-to-use device that provides fast and efficient heating of the garage. It differs from a fan heater by several times higher power of heating elements. The apparatus is based on electric heaters and a high-performance fan, which provides intensive air blowing of heating elements, causing the rapid distribution of heat in the room.
Connection of heat guns of increased power requires a three-phase power supply with a voltage of 380 V, less powerful units are designed for 220 V.
In garages of a small area, the use of heat guns creates dust in the air, so they can be effectively used there only if the room is kept clean at all times, including through high-quality finishing of building envelopes.
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, reaching the surface of objects in the path of propagation, heat them, and those, in turn, give off heat to the room. Such devices are sometimes referred to as UFO heaters, but UFO, the common Cyrillic abbreviation of the same name, has nothing to do with ultraviolet radiation.
UFO heaters are available in various sizes and capacities, they can be on a leg or designed to be mounted on a vertical or horizontal base (wall, ceiling). Provided that the housing is waterproof or placed under a canopy, infrared heaters can also be used in front of the garage on the street.
Advantages of IR heaters:
- economical consumption of electricity;
- ease of operation and installation;
- reliability, safety and environmental friendliness.
The disadvantage of infrared heaters when used in a limited garage space is the effect of IR 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! Significant heating of the body of UFO heaters during operation requires caution in 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 owner of the garage, then water heating is best way heating a major garage of large dimensions.
- advantages - a high level of automation of the heating system, when using natural gas - the constant presence of an energy carrier in the main, efficiency and high efficiency of gas equipment;
- disadvantages - the presence of a risk factor for explosion, fire or carbon monoxide poisoning.
Using gas heating the owner of the building must especially strictly observe safety requirements in his garage.
A good option for a garage is a steam-drop type condensing automatic unit, which is up to 15% more economical than other models, as it is able to work efficiently at low gas pressure. In the heat exchanger of such a boiler, water from being heated by a gas burner turns into steam, and then again condenses into a liquid state, which is accompanied by the release of heat. Such boilers are produced in floor and wall versions. For a garage, the second option is preferable, excluding the possibility of tipping over when performing some work.
Electricity
Heating with an electric boiler is a rather expensive solution to the heating problem for a garage. If there is no alternative type of fuel, then it is better to use electrical appliances (convectors, fans, heat guns, UFO heaters - described in detail above).
When using electric heating equipment indoors with an open arrangement of heating elements (spirals, heating elements), it is necessary to remove flammable and combustible materials (fuels and lubricants, solvents, paints, tow, etc.) from the garage.
Pyrolysis boiler long burning Atmos made in the Czech Republic To date solid fuel boilers are in demand by owners of housing and industrial buildings along with gas equipment. The fuel is coal, sawdust, firewood. This is a fairly economical heating, well providing the room with heat.
Disadvantages of heating a garage with a solid fuel boiler:
- the need for smoke removal;
- the need to allocate a significant area for arranging a place to store fuel, which is not always possible in a garage;
- the danger of being in the garage of everything that can ignite from a spark when the firebox door is opened;
- the need for regular cleaning of the furnace from ash, and pipes - from soot.
The most advanced and therefore economical type of solid fuel boiler is a pyrolysis type unit, where the fuel decomposes under the influence of high temperatures into two components - pyrolysis gas and ash, each of which is burned almost without residue in a separate chamber.
In most models of pyrolysis boilers, only wood, pellets and waste (not bulk) from the woodworking industry are used as fuel. However, universal units are also produced, also designed for the use of coal and peat briquettes. The only common condition for all models is that in order for the boiler to enter the pyrolysis mode, the moisture content of the fuel 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 - it is really economical to heat a garage with your own hands only when all components of the process do not require significant costs.

It is not difficult to build a stove by watching the corresponding video.
Mining as a type of fuel
There are special furnaces that are used as fuel, the consumption of which is up to 1 liter per hour.
The disadvantage of this heating method is the need to clean the oil in special installations (you can make it yourself), since burning used lubricating fluids without first adapting the fuel to the process is fraught with failure of the furnace.
Air heating system for garage
It is not as popular with garage owners as water, but with its help you can not only heat, but also ventilate the room.
The method consists in equipping the garage with an air duct with deflectors through which air is supplied, which is blown by a 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 effect of moisture on the car and other furnishings.
To reduce heating costs, the owner is recommended to insulate the outside walls and ceiling in the garage, having previously sealed all the cracks and holes. For thermal insulation of walls, you can use foam sheets, for the ceiling and floor - expanded clay. The use of mineral wool boards will require subsequent waterproofing
The right garage heating system will not only provide a comfortable temperature regime indoors, it will protect the enclosing structures from dampness, but also prevent the development of corrosion on the metal parts of the car, which is detrimental to equipment.
Motorists often form a special relationship with the garage. They perceive it as a cozy place where they can do what they love - taking care of the car, spend their free time there, and try to create the most comfortable conditions. Therefore, the arrangement of the heating system is necessary not only to ensure acceptable storage conditions for the machine, but also for the convenience of its owner. Garage heating should be inexpensive, efficient and safe. What system to mount? Each motorist makes his own choice. Consider which options are most common, find out the reasons for their popularity, analyze the advantages and disadvantages. The goal is to find the most economical heating, which will give the best result with the minimum burden on the budget.
Comparison of heating sources among themselves
If the building is located at a distance of no more than 20 m from the house, the problem is solved automatically - they equip a common system with the house. For garages located further away, autonomous systems are needed, and as heat sources can be used: gas, electricity, solid fuel and used engine 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 garage heating is, of course, with the help of gas, but it requires connection to the central highway, paperwork, permission from the competent authorities. Despite the numerous tips for self-installation of gas systems available on the network, we will not recommend the installation of gas systems with our own hands. Study gas systems should only experts. In addition, you can install equipment 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 simple way of heating is the use of liquefied gas. Convectors, ceramic stoves, gas panels, heat guns, infrared heaters are installed as heating devices.
The main advantages of gas heating:
- profitability;
- high efficiency;
- high degree of system automation;
- 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, it is associated with troubles and costs.
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
The option of installing an electric heating boiler for the majority disappears immediately, because more expensive heating cannot be invented. But a portable electric heater for the garage is the choice of many motorists. It perfectly solves the problem of maintaining the desired temperature, you can always choose the model of the desired 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 there. As heating devices use,.
Please note if you are planning to install electrical equipment for heating, you need to take care that there are no combustibles, lubricants, paints 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 be a worthy alternative. Electricity costs are high anyway, but a mobile heater is cheaper and doesn't require installation.
Heating with solid fuel
Solid fuel allows you to create a completely autonomous heating system that does not depend on either the presence of an electrical network or a gas main. You can put a stove in the garage or equip heating with a solid fuel boiler. Wood, coal, sawdust are used as a heat source. It is economical, provides thermal comfort, if desired and with the necessary skills, the stove can be made by hand. Disadvantage: it is undesirable to store combustible and flammable materials indoors. work heater must be constantly monitored. The furnace or boiler must be cleaned periodically.
If there are materials, time and desire, the owner of the garage can make a homemade potbelly stove and save on heating arrangements
Mining - alternative fuel
For an economical owner, just a gift of fate, because the use of recycled materials allows you to reduce heating costs to a minimum. Approximate fuel consumption - 1 liter per hour. Oil before use must be cleaned in special heating plants. Such an installation can be assembled independently. The only serious drawback of the mining stove is that it can fail, since the fuel is of poor quality, it is impossible to achieve uniformity in its composition.
The device of the furnace, working on recyclable materials, is simple. If desired, both the oven and the oil purification system can be made by hand
The best heating boilers
When the issue with the choice of energy carrier is resolved, it is necessary to determine the type of heating boiler. It should be economical, easy to use, different 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 ability of the boiler to operate at low pressure. In the heat exchanger of the unit, water changes from a vapor to a liquid state, which leads to the release of heat. Thanks to this principle of operation, 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. Best to buy. The principle of operation 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. The gas is burned. For the operation of the boiler, a buffer tank is needed, it accumulates heat. Of all the solid fuel models, pyrolysis models 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 effectively heat the 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 the power and save, an additional plus is silent operation. There is only one minus, but a significant one: heating with electricity is always expensive, because. electricity is the most expensive source of heat.
Most cheap heating for a garage - a gas condensing boiler, other types of units can be more affordable, convenient, but they are all more expensive to operate
What is better for a capital garage?
An insulated garage made of brick, concrete or shell rock is usually well insulated, so you can save money by equipping proper heating. Most often design water systems; air ones are used less frequently, but are also popular. If we compare these systems in terms of capital costs, then at first glance, air seems cheaper, but operating costs are of fundamental importance, and from this point of view, water is better. Properly designed and well-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 recommendations of the manufacturer, noted in the instructions. For batteries, holders are attached with wall dowels, after which radiators are hung at a height of 15 cm from the floor. Pipes are connected with fittings.
There are no particular difficulties in the installation of water heating, it is quite possible to do it yourself. If you do not have the necessary skills, then it is better to entrust this work to specialists. If planned, be sure to invite the gasman, do not take risks by installing and connecting the equipment yourself.
Air heating systems
Principle of operation air heating It is based on the creation of warm air currents that quickly warm up the room. If the system is installed in such a way that the air flows in the direction of the place where the machine is standing, it is possible to achieve efficient 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 the required power. Most often, motorists choose fan heaters and thermal curtains for garages.
Infrared Electric Heaters
These devices are popular due to the 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 objects and people, so that heat is not dissipated in vain. The air in the heated room infrared heater, warms up indirectly - from 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 the same - the high cost of electricity.
Summary
Not only the temperature regime in the room depends on the choice of the heating system for the garage, but also the durability of the car, the feeling of comfort for the owner. Cold and dampness in the garage are unacceptable, as they stimulate corrosion processes and adversely affect the condition of any equipment. Decide on the most affordable source of heat, consider which system will be convenient - and get down to arranging a comfortable garage. Good luck!
