Most car enthusiasts use the garage not only for its intended purpose, but also as a room where they can take a break from household chores, do hobbies or do some household chores. To ensure that your stay in the garage remains comfortable in winter, the room must be heated somehow.
In order for heating to be economical, you need to know the features of existing heating methods, since you can choose the optimal one for yourself only taking into account the specific situation and a number of factors: the dimensions of the room, its distance from housing, the availability of fuel consumed, the budget for providing the garage with heat, etc. d.
Heating options for a standard one-car garage
The most popular and most economical method is heating the garage with electricity, especially if the building is located some distance from the house, has small dimensions and is not visited often in winter.
There are several ways to heat a garage using electricity.
Convector
Models of electric convectors for use in garages and other technical premises
A reliable and efficient device, the operating principle of which is based on air convection initiated by heating elements - cold air enters the device from below and, heating up upon contact with the heating element, rises warm to the top.
Convectors are available in floor-mounted, wall-mounted or universal versions - on support legs, with brackets for mounting to the wall, or equipped with both mounting options. The latter version is especially convenient, as it allows you to compactly place the heater on the wall with the possibility of quick dismantling and installation next to the car - at the place of repair.
Advantages of an electric convector:
- quick heating to working condition;
- heating in automatic mode - a certain temperature value is manually set, upon reaching which the device turns off and resumes heating the room only when the air cools by 1 degree;
- safety of operation and ease of routine maintenance;
- durability;
- Possibility of use in rooms with high humidity and pollution, since the operating elements of the device are covered with a protective housing.
Disadvantages of the convector:
- higher cost compared to some other types of electric heaters (quartz);
- the effect of operating a convector in a garage is achieved after at least half an hour;
Portable floor-mounted high-power fan heater for household and industrial needs Operating principle: a heat exchanger (heating elements or coil) is heated by electricity, air from the room is pumped into the heater by a fan, passed between the heating elements and returned hot to the garage.
Advantages of a fan heater:
- environmental friendliness - the absence of any emissions into the surrounding space during operation;
- ease of adjusting the heating intensity - there are switches for heating modes (turning off some heating elements) and fan rotation speeds;
- small dimensions and mobility - can be installed anywhere in the garage;
- the possibility of focused heating of zones or objects;
- quick heating of the room;
- equipped with automatic shutdown devices in case of overheating or overturning;
- the possibility of additional independent configuration with an electromechanical thermostat to automatically maintain the set temperature in the room;
- low cost of electrical appliances of low and medium power;
- ease of operation and maintenance.
Like any unit, The fan heater also has disadvantages which must be taken into account:
- accompanying heating, a decrease in air humidity in the room;
- the presence of dust accumulation on heating elements, fraught with fire or, at least, an unpleasant odor in the garage;
- noise caused by the operation of the fan;
- increased electricity consumption.
Despite these disadvantages, the use of a fan heater is the most popular heating option for a garage.
Lightweight Timberk heat gun with handle for easy movement A compact and easy-to-use device that provides quick and effective heating of the garage. It differs from a fan heater in the significantly higher power of heating elements. The device is based on electric heaters and a high-performance fan, which provides intensive air flow to the heating elements, causing rapid distribution of heat in the room.
Connecting high-power heat guns requires a three-phase power supply with a voltage of 380 V; less powerful units are designed for 220 V.
In small garages, the use of heat guns creates dust in the air, so they can be used effectively only if the room is constantly kept clean, including through high-quality finishing of the enclosing structures.
Infrared heater
Infrared heaters in various designs: tripod, wall and ceiling The operation of the device is based on the emission of infrared rays, which, upon reaching the surface of objects along the propagation path, heat them, and they, in turn, give off heat to the room. Such devices are sometimes called UFO heaters, but UFO, the common Cyrillic abbreviation of the same name in everyday life, has nothing to do with ultraviolet irradiation.
UFO heaters are available in various sizes and power; they can be on a leg or designed to be attached to a vertical or horizontal base (wall, ceiling). Provided the housing is waterproof or placed under a canopy, infrared heaters can also be used in front of the garage on the street.
Pros of IR heaters:
- economical electricity consumption;
- ease of operation and installation;
- reliability, safety and environmental friendliness.
The disadvantage of infrared heaters when used in a confined garage space is the effect of infrared rays on a small area, which causes less heat transfer from objects into the air. But when focusing radiation in the direction of the actual zone, these heaters are quite effective.
Important! The significant heating of the housing of UFO heaters during operation requires caution when handling the device in a cramped garage.
Water heating of a large capital garage
The most familiar to consumers, the use of which in spacious garages is justified by many factors, including the possibility of do-it-yourself installation. If the cost of purchasing a heating boiler, radiators and other components does not bother the garage owner, then water heating is the best way to heat a large permanent garage.
- advantages - high level of automation of the heating system, when using natural gas - constant availability of energy in the main line, cost-effectiveness and high efficiency of gas equipment;
- disadvantages - the presence of a danger factor of explosion, fire or carbon monoxide poisoning.
When using gas heating, the building owner must especially strictly observe safety requirements in his garage.
A good option for a garage is an automatic steam-drip condensing unit, which is up to 15% more economical than other models, as it can operate efficiently at low gas pressure. In the heat exchanger of such a boiler, water from heating with a gas burner turns into steam, and then condenses again into a liquid state, which is accompanied by the release of heat. Such boilers are produced in floor-mounted and wall-mounted versions. For a garage, the second option is preferable, eliminating the possibility of tipping over when performing some work.
Electricity
Heating with an electric boiler is 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 open heating elements (coils, heating elements), it is necessary to remove flammable and combustible materials (fuels, lubricants, solvents, paints, tow, etc.) from the garage.
Long-burning pyrolysis boiler Atmos made in the Czech Republic Today, solid fuel boilers are in demand among homeowners and industrial buildings on a par with gas equipment. The fuel is coal, sawdust, and firewood. This is a fairly economical heating system that provides the room with heat well.
Disadvantages of heating a garage with a solid fuel boiler:
- need for smoke removal;
- the need to allocate a significant area for arranging a fuel storage area, which is not always possible in a garage;
- the danger of having anything in the garage that could ignite from a spark when the firebox door is opened;
- the need to regularly clean the firebox from ash and the pipes from soot.
The most advanced, and therefore economical, type of solid fuel boiler is a pyrolysis type unit, where the fuel, under the influence of high temperatures, decomposes into two components - pyrolysis gas and ash, each of which is burned practically without residue in a separate chamber.
Most models of pyrolysis boilers use only wood, pellets and waste (not bulk) from the woodworking industry as fuel. However, universal units are also produced that are also designed for the use of coal and peat briquettes. The only common conditions for all models is that in order for the boiler to enter the pyrolysis mode, the fuel humidity should not exceed 20%, otherwise it will work like a conventional solid fuel heater.
However, pyrolysis-type boilers are expensive equipment, and therefore not every consumer can afford to use them to heat a garage - heating a garage with your own hands is truly economical only when all components of the process do not require significant costs.

It’s not difficult to build a stove by watching the corresponding video.
Processing as a type of fuel
There are special stoves that use as fuel, the consumption of which is up to 1 liter per hour.
The disadvantage of this heating method is the need to purify the oil in special installations (you can make it yourself), since burning waste lubricating fluids without first adapting the fuel to the process can lead to failure of the furnace.
Air heating system for garage
It is not as popular among garage owners as a water heater, but with its help you can not only heat, but also ventilate the room.
The method consists of equipping the garage with an air duct with deflectors through which air is supplied, pumped by the fan of a heat gun or fan heater and additionally passed through an air filter.
The main advantage is the rapid simultaneous drying of the entire volume, which prevents the aggressive effects of moisture on the car and other furnishings.
To reduce heating costs, the owner is recommended to insulate the outside walls and ceiling of the garage, having previously sealed all the cracks and holes. For thermal insulation of walls, you can use foam sheets, and expanded clay for the ceiling and floor. The use of mineral wool slabs will require subsequent waterproofing
A properly selected garage heating system will not only ensure a comfortable temperature in the room, 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.
Recently, people are increasingly choosing infrared heaters for their garages. First of all, this is due to efficiency. They are not very expensive and at the same time consume a small amount of electricity. Additionally, they have convenient controls. All infrared heaters have a regulator that allows you to adjust the temperature. If you do not always use the device to the maximum, you can save significantly.
Installation of infrared heaters
Installing infrared heaters in a garage is very simple and anyone can do it. The main thing in this situation is to carefully read the device instructions. It should indicate all installation recommendations that apply to a specific model of infrared heater.
Recently, devices that can be mounted on the ceiling have become popular. This can significantly save space in your garage. You can carry out the installation completely independently. This will require brackets as well as dowels. Additionally, you can use various hooks.
How to make a heater with your own hands?
In principle, it is possible to make an infrared heater for a garage with your own hands. First of all, you need to purchase two small sheets of plastic. You will also need epoxy glue along with graphite. For heating, use a plug with an electrical wire. At the first stage, a layer of glue is evenly applied to the plastic sheets. Next, a little graphite is added to the homemade garage heater.
The next step is to join the plastic sheets together. Then you can begin installing the electrical wire. You can also make your own garage heater with a voltage regulator. As a result, it will be possible to change the temperature. However, you must always remember that a homemade garage heater can lead to a fire if assembled incorrectly.

Every motorist knows how much time and effort is spent on car maintenance and repair.
If you violate the rules for maintaining your “iron horse,” the car may break down at any moment. In winter, when the temperature outside is sub-zero, you also periodically have to look for and correct malfunctions in the operation of the car, so it is necessary to create normal conditions for its maintenance.
A homemade garage heater, which has a simple design and can be made with your own hands, can help you with this.
In accordance with the rules for car maintenance, the temperature inside the garage should not be lower than +5 degrees. The heater can also help you out when yours is heated by central heating, which is not able to heat the garage sufficiently. In addition, the heater can be useful in severe frosts in order to start the car without problems.
Primary requirements
Since the garage is a small space, a homemade heater installed in it must meet these requirements:
- when the heater is operating in a garage, the amount of oxygen it burns and the level of toxic substances it emits should be minimal;
- according to safety regulations, the risk of fire and explosion should be completely eliminated;
- the device should not take up much space or interfere with movement around the garage;
- the heater must be such that it can heat the room in a short time, and then maintain the required temperature in it for a long time;
- the funds spent on creating a heater should not exceed the cost of factory analogues.
The device must meet all these requirements. Making such a homemade garage heater is not difficult; you will need glue, nichrome wire and PCB sheets.
Creation of a prototype and stages of work
As a basis for a homemade heater, you can take the principle of operation of the “Good Warmth” heater, which has become popular due to its ability to very quickly warm up small rooms. It does not consume much electricity, and distributes heat evenly throughout the room.
This heater has a fairly safe and simple design. The main heating element in this device is enclosed in a material that completely eliminates the possibility of fire. In addition, it is quite small in size and takes up little space in the garage.
If you connect a timer to such a homemade heater, its operating mode can be adjusted. In winter, the “one hour on, two off” mode is quite suitable.
It is capable of warming up the garage to a comfortable temperature in one hour and over the next two hours you can safely carry out car repairs. When it gets warmer outside, you can change the timer settings.
Preliminary testing of the heater
First you need to determine the appropriate power of the heater, for which preliminary testing should be carried out. For this, you can use available materials, so you will not incur large costs.
Nichrome wire is a semi-finished product made from an alloy of chromium and nickel. This wire has fairly high resistance values.
In this alloy, the percentage of nickel is about 80%, which ensures corrosion resistance and ductility, and chromium, which is present in the alloy, gives it resistance to fairly high temperatures and high hardness.
If you do not know the resistance of the wire, then you will need to install it, for which you need to cut one meter of wire and twist a spiral from it. Next, you need to place a thermometer inside the spiral, and then connect the wire to some kind of power source with a transformer.
When the thermometer reaches a temperature of 40 degrees, you will need to record the readings of the voltmeter and ammeter, with which you can determine the resistance of the conductor. You can find the wire resistance from the table if you know its diameter.
Since your homemade heater will operate from a 220 volt network, you need to find out how many meters of wire you will need to obtain alternating current with a power of 100-120 units. For example, you will need 24 meters of nichrome wire having a diameter of 0.3 mm to end up with a 100 W heater.
Step-by-step manufacturing of a heater
In order to make a homemade garage heater, you will need a sheet of textolite, the thickness of which should be no more than 1.5 cm. This sheet will become the basis for a heating coil made of wire. Textolite, divided into two parts, can protect against hot wire and quickly warm up a cold room.
The entire surface of a textolite sheet is heating, but in order to warm up the garage, you will need a piece of material measuring 0.5x0.5 meters on both sides of the heater.
The device can be of any rectangular shape; it does not have to be square. The main thing is that both parts of the PCB are the same, and that the wire spiral is securely closed.
- On the inside of the heater, the PCB sheets must be treated with sandpaper.
- After this, markings should be applied to them - 2 cm should be left from the top and bottom edges, and 3 cm on the sides.
- After marking the boundaries, you need to calculate how many folds there will be with a length of 24 meters. The winding pitch should have a length equal to the distance from the marked upper boundary to the lower boundary, and the boundaries themselves do not need to be taken into account.
- After the number of folds of the wire has been calculated, it will be necessary to measure the distance at which its turns will be located. In this case it will be approximately 8-13 mm. Along the edges of the border, you need to drill small holes in accordance with the calculations, and then insert marks into them - toothpicks or matches.
- Then you need to drill two more holes, which will be the exit for the wire coming from the power source.
- Next, you need to carefully lay the wire like a snake, without pulling it. Matches will help you form the heating element. After five to seven turns of wire have been laid, you will need to secure them with paper strips. Paper 1 cm thick and Monolith glue can be used to fix the filament.
- After the matches are removed, the edges of the snake will also need to be secured with strips of paper.
- Metal rivets must be inserted into the holes intended for the power cable, onto which the end of the snake should then be wound.
- Finally, you need to attach a washer to the rivet on the outside of the heater, which is needed in order to securely fix the contact.
The power cord can also be connected inside the heater, next to the filament coil, for which it is necessary to strip the ends of the electrical wire and wind them around the inside of the heater with rivets.
Another example of a very simple heater:
Powerful electric heater for the garage made of concrete pipe and nichrome wire.
Appearance, testing and performance check
The final stage in the manufacture of a heater is testing it for operability and safety. The first step is to connect the heater to an ohmmeter, and then to a power source.
To increase the strength of the heater, you can coat the inside of it with epoxy glue. If the size of the heater is 0.5x0.5 meters, then you will need about 150 g of glue, which must be applied along the snake.
Then the structure is covered with the second half of the PCB, and in order for it to set well, it is necessary to install a load weighing approximately 40 kg on it.
You will be able to use your homemade heater within 24 hours. Its surface can be decorated using some finishing material (plain fabric, vinyl film, etc.).
You can also rivet PCB sheets and install fasteners on their surface for wall mounting. When leaving the garage, you must always turn off the heater, especially a homemade one.
Creating such a heater is quite simple and does not require a lot of money. You will not only acquire knowledge that will allow you to make a good heater in just a couple of days, but you will also enjoy the creation process itself.
To relax in the countryside in winter, you need a reliable source of heat (heater). It can be purchased in specialized stores. But there are summer residents who can easily design homemade heaters for their home, cottage and garage.
Not all summer residents and homeowners come to this decision, but only those who have special skills and abilities. Among them there are real self-taught engineers. They are able to calculate everything down to the smallest detail, carefully handle every detail, installing an original safe heater.
The cost of material for a homemade device for heating a room is minimal, since it can be found on the farm. Even if you buy the material for money, it will cost much less than a device from a store, and the effect of the work is the same. Why then spend money on purchasing ready-made equipment when you can install it yourself. How to make a home heater with your own hands?
Homemade gas heater for garage, home, cottage
When creating a heater with your own hands, you need to follow several recommendations:
- The device must have a simple design without complex elements and parts.
- It is necessary to focus special attention on safety, therefore it is best to purchase devices that shut off and supply gas from the factory, or remove them from old cylinders.
- When creating, you should also take into account its cost-effectiveness.
- The heater should not be bulky, and the methods for activating it should not be complicated.
- The cost of materials for the heater should be no more than a third of the real price of a factory heating device from the store counter, otherwise there is no point in making it; it’s easier to buy a ready-made one.
As practice shows, the most effective way of heating at home is infrared radiation.
To make such a homemade gas heater for a garage, home, or cottage with your own hands, you need a minimum of parts and material costs (tin sheet, metal scissors, rivet gun, rivets, fine metal mesh, regular household sieve, drawstring gas canister with a capacity of 0.5 l. and a special burner with a valve).
The first thing you need to do is attach the heater to the burner. You need to take a household sieve, lean it against a galvanized sheet and circle it with a marker. Then, perpendicular and parallel, it is necessary to draw rectangular ears to the circle (one of them should be twice as long). Use metal scissors to cut out the design. It should be as smooth as possible.
The second stage of heater installation involves fastening the parts together. To do this, take the burner and bolt it to the tin circle. Then, using the ears, which are wrapped in the opposite direction, a strainer is attached. It helps dissipate heat to the sides. The result is part of the heater design.
The third stage of installing a homemade heater will be attaching the metal mesh. To do this, you need to cut out an identical circle from the tin again. It is also cut with metal scissors. The ears are bent, and holes (about 10) are drilled in the plane of the circle. Then the mesh is taken and attached to the ears of both circles. First you need to attach the lower part, then the upper. Fastening is carried out using a riveter and rivets. The result of these operations should be a mesh cylinder.
The final stage is the launch of an infrared homemade gas heater. Although it is not large, the heat emanates from it is sufficient to heat a garage, a room in the house or a small country house.
DIY oil heater
Thanks to their impeccable functionality, characteristics and efficiency, they have gained great popularity among summer residents. They are safe and compact, and have a high level of efficiency.
The design of a homemade oil heater is very simple: a sealed housing with oil (any gas cylinder or other sealed container can do), around which electric tubular heaters are wrapped.
To make an oil heater, you need the following materials and tools:
- Hermetic container (car radiator, metal or aluminum battery).
- Transformer or technical oil.
- 4 ten.
- Electric motor or pump of low power (up to 2-2.5 kW).
- Set of drills, drill, welding machine, electrodes, switches.
The process of installing an oil heater at home follows the following scenario:
A DIY oil radiator will be an excellent and effective heater for your home and garden. Its only drawback is its dependence on electricity and its high consumption.
DIY electric heater
If you make an electric heater with your own hands, the basis of its operation should be infrared rays, which heat not the air, but the objects in the room. Thanks to this principle, even a homemade electric heater will be effective. In addition, electricity consumption is minimal.
To make an electric heater, you can use two sheets of plastic and graphite shavings. The owner will get an aesthetic, flat device that will harmoniously fit into any interior.
A graphite heater is made using graphite shavings (you can use old, used tram brushes), two sheets of plastic (1 m2 each), epoxy glue, a piece of wire with a plug at the end.
A homemade electric heater is the most effective and convenient means of heating a room. Many summer residents are often interested in the question of how to make a garage heater with their own hands? For a garage, you can make a heater using the same principle, only you need to take smaller plastic plates, about half the size. This will be enough to heat a small garage.
Video: making a heater with your own hands
For heating a garage can be done in a variety of ways(we do not consider central heating):
- using electric heaters - the most common, simple, but far from cheap heating method;
- using a wood (coal) stove - cheap, with free fuel available, plus it takes away working time;
- using a diesel fuel heater - a good option, quick heating, again - significant costs for purchase and fuel.
- using a waste oil heater is a good option, especially if there is enough waste.
- other options are more exotic or classic stationary heating systems, which are installed when building a garage.
There are many advantages when using an electric heater - simplicity, no need to stock up on energy raw materials, low acquisition costs, convenient location, does not require maintenance, etc. The main disadvantage is high energy consumption and, accordingly, costs.
Offered homemade version of an economical electric heater for use in a garage or similar premises.
As the main components of the structure homemade heater A radiator from any car, a pump (car water pump) with a fan and pipes, and an electric motor are used. You can take the radiator even with partially clogged pipes; this will not prevent it from working. Instead of a car radiator, you can take a radiator from any industrial refrigeration unit. The electric motor used has a power of approximately 0.3-0.8 kW and ensures a rotation speed of at least 1500 rpm.
The basis of the heater is a frame, which is welded from a steel angle. In order to be able to move the heater, it is more convenient to place it on wheels made of any rollers that are mounted on the frame. The engine, water pump, starter and radiator are mounted on the frame. Three heating elements are placed in the lower radiator tank, each with a power of 1 kW, operating at a voltage of 220 V. The best option would be a triple heating element, which has a common threaded shank. The heating element is secured in different ways, for example, you can cut a hole in the lower tank and solder a threaded ring for the shank of the heating element to its edge.
Description of the design of a homemade electric heater for the garage:
1 - radiator; 2 - expansion tank; 3 - fan; 4 - fan casing; 5 - pump; 6 - pipes; 7 - magnetic starter; 8 - V-belt; 9 - electric motor; 10 - frame stand; 11 - drain tap; 12 - heating elements; 13 - blinds
Performance homemade heater can be adjusted using the number of heating elements connected to the network, thus regulating the temperature.
To set the electric heater to the most efficient mode (at a liquid temperature in the radiator of 80 ° C), the diameters of the pulleys are selected. To compensate for the expansion of the liquid when heated, the installation uses a car expansion tank.
A more complex version of the electric heater design allows you to maintain the set temperature. To do this, it is enough to connect the electric motor to the network not directly, but through the chamber temperature sensor DTKB.
The most suitable electric heater fluid is transformer oil. It heats up quickly, cools very slowly and does not freeze even when the temperature drops significantly. Instead of transformer oil, you can use automotive antifreeze brand A-40.
The tension of the belt connecting the electric motor to the pump and fan can be adjusted by moving the pump and fan in the prepared mounting grooves in the frame.
Sawdust heater
Sawdust and small wood chips that remain after construction can be successfully used to heat a garage or even a country house if you install a tray made of 2-3mm thick steel sheet with a hole in the middle in a regular “potbelly stove.” The tray needs to be made removable so that when the sawdust runs out, the stove can be heated with wood again.
It is advisable to use such stoves for those who live near logging sites, where sawdust will be almost free.
The stove is used like this: a conical stake is inserted from above through the hole in the stove (it needs to be adjusted to the hole in the pan so that there is no gap). Sawdust is tightly packed into the space around the stake. Careful that they do not fall into the hole, remove the stake, close the stove and light the wood from the bottom of the tray through the stove door. The sawdust catches fire and smolders. The stove heats the room all night (5-7 hours).

Homemade garage heater with flameless combustion
The principle of its operation is that fuel vapors - alcohol or gasoline - are oxidized by atmospheric oxygen using a catalyst. This happens directly on the heating element. Thermal energy is not produced by the combustion of fuel, but by a chemical reaction that occurs.
This DIY garage heater it's done like this. Take a fuel tank that has a neck and a plug. An old car fuel tank is best suited for this. Next is the burner, into which the heating element is placed - a frame and two iron meshes - equip them with a gasket, preferably made of asbestos wool, impregnate it with a catalyst. Make the wick made of cloth or you can also use asbestos wool. It will supply gasoline from the tank to the burner. Place the upper part of your wick evenly under the mesh, and place the lower part at the bottom of the tank. Fill the free space in the tank with cotton wool.
Homemade heater design: 1 - slide tube, 2 - tank body, 3 - tension lock latch, 4 - latch axis, 5 - stand with lock lugs, 6 - tension bracket, 7 - cover, 8 - rivet, 9 - handle, 10 - nichrome wire, 11 - asbestos wool impregnated with a catalyst, 12 - clamping frame, 13 - metal mesh, 14 - heating element frame, 15 - seal, 16 - tank neck plug, 17 - neck, 18 - asbestos wool, 19 - wick, 20 - internal bulkhead, 21 - burner body. A - mirror of the heating element (b X e).
When installing the heating element into the burner, place a wire gasket (5 mm cross-section) between the frame and its installation location. Wrap the wire with corded asbestos. This DIY garage heater should have a metal cover that fits over the top of the burner, thereby stopping it from working.
Pour 100 ml of gasoline onto the heating element grid and set it on fire. Soon the fire will go out, and gasoline vapors from the tank will begin to leak to the heated surface. Because of the oxygen in the air, with the help of a catalyst, they will begin to oxidize and increase the temperature. That is, flameless combustion will begin to occur.
The heating element is made of long-fiber asbestos. It must be impregnated with a cobalt-chrome catalyst for 1 hour. It is made from the following reagents - cobalt and manganese nitrates, ammonium chloride and ammonia (concentrated). During impregnation, cobalt chromate will settle on asbestos. It will need to be dried at +120 C, loosened, and calcined at + 400 C for 3 hours. Then lay the mixture in an even layer between the meshes.
Important! When operating this heater, protect its working surface from oil, water and dirt.
And another option for a homemade electric heater for the garage
Solving the problem of heating a garage using homemade electric heaters with open coils is not permissible, since gasoline fumes, sometimes present in garages, and their contact with an open heating element can lead to tragic consequences. Portable industrial electric heaters are also not the best solution to the problem, since they have low heat output.
One of the effective options for heating a garage is a water-type heating system with an individual heat source. You can arrange heating in the garage using this principle yourself, after first familiarizing yourself with the diagram shown in the figure.
The figure demonstrating the connection of the pipe shows:
Coupling nuts
- washers
- sealing gaskets
- boiler walls
- pipe branch
Figure B shows the heating diagram, it uses the following elements:
- expansion tank cap
- expansion tank
- boner
- electric boiler
- connection of pipes with sealing
- pipe branch
- connecting hoses
- metal convector plates
- convector pipes
- heating element power supply terminal
- the heating element itself
- control valve
- drain tap
The operating principle of this homemade heating system is based on the difference in the volumetric weight of hot and cold water, which is why a unidirectional flow of heated liquid occurs in this system. Water heated by the heating element in the boiler rises to its upper part and flows through pipes to the convector. There it gives off heat to the room, cools and becomes heavier, as a result of which it falls down and again enters the boiler. In this regard, the boiler must be located below the radiator (convector) - this helps to increase the speed of water movement and circulation pressure in the heating system.
Good luck, and may your garage always be warm.
