Choosing the most economical way to heat a garage in winter

If anyone thinks that a garage is just a place to park a car, it’s women. Little do they know that the garage is actually a men's club, where you can not only repair the iron horse, but also receive friends. One problem is that in our climate from October to April the air temperature does not allow much lingering in unheated rooms. Today we will take a closer look at the types of heating and choose the most economical method. Heating a garage and everything you need to know about it is in our material.

A warm, cozy car box is just a home for most car enthusiasts

What to think about at the preliminary stage

Rarely lucky people are lucky enough to have a centralized heating system in their garage. This is possible if you have a shared indoor parking space or the garage is located directly in the structure of a country house.

In the remaining 99%, the stall for the iron horse is located in a garage cooperative and is a brick or metal bunker without any amenities

Therefore, the heating system must be autonomous. Before you consider purchasing a heating device, do your homework. What should be done:

1. The garage needs to be insulated. Simply heating an iron bunker is literally throwing money away. Brick, metal or sandwich - all this needs additional insulation. You need to make sure that all cracks are securely caulked. It is better to place the heat insulator on the outside of the walls, but if this is not possible, the inner layer will also work. Particular attention should be paid to the floor - this is also a large area for heat loss. It should be covered with insulating material.

   
   Don’t forget about the roof - otherwise all the heat will escape through it

2. It is necessary to provide high-quality ventilation. Sad statistics show that most tragic incidents in garages occur in winter. Careful insulation of the room does not allow for normal air exchange. Simply warming up the car for a few minutes before leaving can end very sadly. What can we say about the situation when the boiler is constantly running in the room.

For car boxes, it is better to use ventilation systems that combine natural and forced ventilation

Fan heater

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 that 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.

Important information for your safety

The second possible danger after carbon monoxide poisoning is a garage fire. There are always flammable materials here, including the contents of the car's fuel tank. Neglect of safety measures is fraught not only with the loss of your garage and your beloved horse, but also with a serious lawsuit from neighbors in the parking lot.

For these reasons, we consider it useful to remind you of the basic rules:

• use low-flammable or non-flammable materials for the construction and finishing of the garage structure;
• do not store large amounts of fuel and oil in this room;
• make it a rule to smoke outside;
• do not carry household rubbish into the garage, it will become the main “food” for the fire;
• keep a fire extinguisher on hand, one day it will save your garage from fire;
• do not install electric heating systems in damp rooms;
• Do not leave your garage heating boiler unattended.

Think about the fact that it would be a good idea to install the simplest smoke detectors in this room.

Modern technologies make it possible to install such systems and connect them to a mobile phone

How to make a potbelly stove during mining

It is not always practical to have a supply of firewood in the utility room. There is a lot of used oil in car workshops. Having an oil-powered potbelly stove on hand is a big deal. You will receive free heat, compared to firewood, which you need to buy and pay for a car to bring firewood.

Testing stoves have general principles of operation. The small chamber is filled with used oil. The oil is set on fire. Bring it to a boil. Oil vapor rises through the pipe. Mixes with oxygen. In the second compartment, oil vapors are burned. According to the materials, the upper chamber of the furnace and the pipe should be as heat-resistant as possible. They account for the highest temperatures. A large-diameter pipe is used as the basis for the mining stove.

There are pipes with a diameter greater than 30 cm. They are well suited for these purposes. The wall thickness will be as follows. Lower chamber from 4 mm. Upper chamber from 6 mm. Cameras are made of arbitrary height. To transition between the chambers, take a good boiler pipe with a diameter of 100 mm or more with thick walls. This pipe will hold the upper chamber on itself. After making the stove, it is coated with heat-resistant paint.

The furnace for the garage being worked on is not described in detail here. There are many descriptions on the Internet. We have only indicated general points.

How can you heat a garage?

So, we are talking about autonomous heating of the room, therefore, we need to choose the principle on which the heating system will operate. If earlier the conversation was only about a banal potbelly stove, now the choice of suitable devices is so wide that we will divide them into several categories.

The most economical ways to heat a garage with electricity

This type of heating is the first option that comes to mind. Indeed, the choice of electrical heating devices is very large. Such units are characterized by high efficiency and reasonable price. And what’s important: they don’t require you to stock up on fuel; it’s always in the electrical wiring.

The first possible method is to use a fan heater or heat gun. In both cases, it is a very compact device that takes up little space in the garage. Install the electric heater for the garage on the floor or on a workbench.

The fan heater heats up a small garage in a matter of minutes, driving air through hot heating elements

The only thing that will bother you is the smell of burning dust and the noise of the fan.

Another option is to use a convector. This method is considered more effective. In addition, convectors can be used in rooms with high humidity. A small, neat convector can be mounted on the wall or moved around the garage on wheels.

This type of heater is convenient because its power is easy to regulate.

Convector type heater. In this publication we will look at the design of convectors, their types, advantages and disadvantages, the secrets of choosing the right one, and a review of popular models and manufacturers.

An electric floor is also a good idea. If you lay the heating cables evenly over the entire floor area, the garage will always be warm. The air temperature can be adjusted using a thermostat. The only thing that is important in arranging such a system is the use of durable materials that can withstand the weight of your car.

Infrared heating is gaining increasing popularity among owners of residential and non-residential premises. The operating principle of the IR heater is based on the effect of infrared rays on the surface. Everything that comes into the field of action of the device heats up and gives off heat to the air.

Important! Keep in mind that IR radiation has a negative effect on car paint. For this reason, it is better not to install this device directly above the car.

Some tips for installing electric heating in the garage:

• all wiring must be insulated using a plastic or metal box;
• Do not use wiring with aluminum content, it is very fragile;
• Sockets in the garage must be grounded and protected from moisture. Don't install them too low to the floor;
• It is better to place the switch for the inspection hole at the top.

A method of water heating in a garage without using electricity

The traditional water heating scheme is as follows: it includes a boiler, a system of pipes and radiators, and an expansion tank. When solving the problem of how to heat a garage in the cold season, consider installing a water circuit. This type of heating is good because the heat in the room is retained for a very long time.

For the water circuit, you can use a single-pipe or two-pipe circuit. In the two-pipe version, heat is evenly distributed over the entire area. Schemes of water heating in the garage for DIY installation with natural and forced circulation:

The only drawback of such a system is the need for constant operation. If you simply turn off the boiler and leave the garage unattended on a frosty day, the water will freeze and burst the pipes. It turns out that you will have to either drain the water during frosts, or constantly maintain the operation of the heating device. So the question arises: if you drain the water, then why have a heating system that cannot quickly start at the right time? Until you fill it up again, until you start the boiler, more than one hour will pass.

Circuit on antifreeze

Continuing the topic of how to heat a garage in winter with your own hands, it should be noted that contour heating is not an entirely hopeless type. What if you fill the circuit not with water, but with antifreeze? Antifreeze is usually used in cars to cool the engine. It does not freeze even at minus 45 degrees, and this is right in our favor.

With such contents, the heating circuit in the garage will not break even in severe frost

For your information! Antifreeze is a toxic liquid, you need to remember this. It can cause burns to the skin and mucous membranes, and the consequences of its impact on the human body can be catastrophic. It is especially dangerous when heated.

If you decide to install heating in your garage using antifreeze yourself, purchase a special mixture for heating systems. It replaces toxic ethylene glycol with propylene glycol, which is not toxic to humans. Such mixtures are more expensive, but they are safe.

It should be remembered that viscous antifreeze heats up and cools more slowly than water. Its shelf life in the system is 5 years. Antifreeze cannot be used for dual-circuit systems.

Gas system

The likelihood that network gas will be supplied to your garage cooperative is very small, but, nevertheless, it is possible to use blue fuel to heat the garage. You can arm yourself with gas cylinders and thus decide how to cheaply heat your garage. Indeed, gas compares favorably in price with electricity. You can use a regular stationary gas boiler with a water or antifreeze circuit. This option is perfect for craftsmen who work in the garage all the time. With the help of such a device, you can heat the room around the clock, without fear of the sudden onset of frost.

If you do not need to constantly be in the garage, you can purchase mobile gas devices.

Guns, heating pads and convectors using blue fuel will quickly and efficiently warm up the bunker

Important! For safety reasons, gas cylinders should be installed in an iron box away from possible flammable objects and at least 20 centimeters above the floor.

It should be noted that the most economical heater for a garage is a gas boiler.

Solid fuel boiler

How else can you heat your garage in winter? There is no need to give up traditional solid fuel. Firewood, coal, pellets, and even manure, if you have enough of it - all this can go into the firebox. You can build a simple oven in the garage with your own hands. By the way, it is the potbelly stoves that have not yet given up their position in the fight against the cold in garage towns. Newfangled electrical systems are still far from popular.

A simple stove can be lined with bricks or stones, this will increase the heat transfer area

Such a heating device requires constant supervision, but for temporary heating it is suitable like no other. You'll stay warm even if your garage's electricity is cut off for non-payment.

Modern manufacturers offer a wide range of small solid fuel boilers that can be used for car bunkers. They are economical, easy to use and compact.

Important! Remember about fire safety: do not store flammable materials near the boiler.

Heating during mining

If you are doing car repairs in the garage, including changing the oil, then the question of what to heat with should not worry you at all. Mining is an excellent fuel for a heater. This garage heater is easy to make with your own hands from scrap materials. The design of the exhaust boiler is quite primitive: two combustion chambers, in one of them the oil burns, in the other - the flammable gas formed in the process. All this together gives a large output of thermal energy.

For a more visual representation, we invite you to watch a video of how to do heating in a garage with your own hands using waste oil:

Important! The space around the drip furnace must be covered with non-flammable material, and a high-quality ventilation system must be provided in the garage itself.

Use of solid fuel

To heat a small area of ​​a room, it is enough to use a garage heating stove in the form of a “potbelly stove”. Ordinary firewood, coal, etc. are suitable as fuel. The disadvantage of its operation is that you need to constantly add firewood to the firebox.

The potbelly stove can be replaced with a more expensive device - a buleryan. You can find out how to heat a garage using it on a special website.

Pros and cons of different garage heating systems

We have examined in detail the different types of heating systems, let's do a comparative analysis of their disadvantages and advantages:

Which of the listed types of fuel to use is up to you. In each specific case, it is necessary to consider the feasibility of one or another heating method.

What type of heating is most profitable?

It all depends on the specific operating conditions and preferences of the garage owner. The cheapest system is a single-pipe water system powered by a gas boiler.

You will have to invest a lot of money in its arrangement, but it is so economical that the costs will be recouped in 1-2 heating seasons. However, this solution is not suitable for everyone.

Gas and diesel appliances equipped with temperature sensors and automation cannot be considered completely energy independent. They require electricity to operate, but no more than a light bulb uses.

You can economically heat your garage using gas cylinders or solid fuel. These options are not suitable if it is not possible to control the operation of the devices, but they are good for heating while the owner is in the garage.

How to choose the most economical way to heat your garage

Once you have decided on the type of fuel, you need to consider the type of heating device required. The heating device should also participate in fuel saving. If you opt for gas heating, it is best to choose a condensing device with automatic control. It can operate in low pressure conditions and consumes gas almost 20 percent more economically than other models.

Wall-mounted boilers are convenient because they take up little space and can be adjusted according to your wishes

Among solid fuel systems, it is better to give preference to pyrolysis ones. They decompose fuel into dry residue and pyrolysis gas. Of all solid fuel systems, these are the most profitable.

The only thing you need to take into account is that such devices do not work on coal.

Electrical devices with thyristor control are the best in their segment. Their power can be adjusted, and thus reduce energy costs.

Heater equipment

What is included with the device?

• plastic tank for diesel fuel 10 liters

• set of wires with chips for connection

• fuel line hoses

• exhaust pipe

• installation platform for the stove body

• guide pipes and tee for air flow distribution

• air intake and exhaust hoses

• air filter

It is necessary so that when air is drawn into the heater and its combustion chamber, excess dust and other particles do not enter.

• muffler

It is mainly required when installing the device in a car. Useless for the garage.

• set of clamps, bolts, etc.

• Well, the stove itself with a fuel pump and a remote electronic control unit

There is also a key fob for remote start.

There is a fan on one side of the stove. From below, air is taken in and exhausted through metal pipes.

The fuel line is connected right next to them.

Approximate calculations

• The entire area of ​​the garage, the number of floors, are determined, and heat losses are calculated separately for any of the rooms (practice shows that under conditions of sufficient thermal insulation, about 800 W of power should fall per 10 meters of square area).
• The ideal type of heater is determined so that its power fully compensates for all energy leaks.
• Calculations of air channels are made so that the diameters of the channels correspond to the productivity of the fan, and there are no obstacles that can make the flow weaker or change the appropriate vector of its movement.

Cheap and fast garage heating: do it yourself

Obviously, it is not at all necessary to order a heating system for your garage from professionals. Here you can do it yourself, provided you fully comply with all safety measures. It is not difficult to purchase and install one of the devices listed in our top list. All of them have detailed installation instructions, and the store salesperson will certainly advise you on any questions you may have.

All that remains is to consider how to make heating in the garage with your own hands in the simplest and cheapest way.

Do-it-yourself air heating of the garage in winter

One of the cheapest and fastest ways to organize heating in a car box is air. Heat is supplied through pipes only to the place where a person works. This way you can save money by not using fuel to heat the entire garage.

In this device, heated air circulates through metal pipes and is supplied through grilles. The efficiency of such a system is more than 90 percent, and the design itself is extremely simple and easy to install. Warming up the room takes just a few minutes. The only negative is the drying out of the atmosphere, but you can get rid of this disadvantage just by ventilating the garage.

Installation of a contour heating system

If your choice fell on a system with a water or antifreeze circuit, you will need to purchase the appropriate boiler and heating radiators. It is best to use metal batteries. Recommendations for this type of heating are in the following video:

Popularity record: heating a garage with a potbelly stove with a water circuit

As we have already said, potbelly stoves are by far the most popular heating device for car boxes. Among such systems, devices with a built-in water circuit occupy a special place. It’s easy to weld the potbelly stove yourself from thick steel, and make the water counter from a small-diameter metal pipe.

For your information! When starting to make your own stove, consider the type of fuel. To store firewood you need a large hole.

In order for water to circulate well in the system, a pump is required. But in principle, you can do without it if you arrange the pipes so that the liquid circulates in them by gravity.

An example of such a system in the video:

Western European experience

If you type the phrase “garage heating” in the search and look at pictures on English-language sites, you will not find any wood-burning or oil-fired stoves in Western European garages. How do local motorists warm themselves:

• electric portable heaters;
• infrared hanging heaters;
• air heating units (heaters).

  
  The suspended air heating unit does not take up useful space in the garage

We have already discussed the first 2 options above. The third method is also far from new: water heated in the boiler passes through a radiator, blown by a powerful axial fan. Ideally, the unit is suspended from the ceiling and distributes hot air throughout the room.

The advantages of this option are compactness, heating speed and the possibility of air conditioning in the summer (cooled water is sent to the radiator instead of heated water).

Heater made from a car radiator

There is one downside - increased costs for equipment, because the coolant must be heated in the boiler and supplied through pipes to the heater. But if the garage is attached to a private house, then the problem is easily solved by connecting the radiator to the building’s water heating system.

Reference. Many garage craftsmen already use such heating, installing a homemade analogue of a heater made from a car radiator and any suitable fan. How this is implemented, look at the video:

Warm, light and flies don't bite

What can drive a man out of a garage? Only cold and hunger. The first one, as it turns out, is not difficult to deal with. You just need to choose the right heating device. And any motorist can install it and operate it competently.

Hunger is more difficult. But, of course, the iron horse will have to remain in splendid isolation if a beautiful wife and lush hot pies await his owner at home

Profitability of heat supply from the network

If you still want to supply heat to your garage with electric current, the most economical method should be considered first. Consumption of electricity makes it possible to acquire a lot of good qualities, namely durability and high efficiency, ease of use, ease of installation of devices, and there is no need for maintenance. It is worth noting that electricity consumption is safe; the devices will operate quietly and will not emit dust. Any of them can be easily changed, as well as the components of the equipment. The garage owner will not be required to obtain permission to carry out the system installation process.

If you are interested in heating your garage with electric current, the most economical method will probably also interest you. One of the main disadvantages of a similar approach is the high price of electrical energy. However, it is possible to organize heat supply with electric current if you install a thermostat that will turn off the system at the moment when the ambient temperature reaches a specific mark.

Gas

In terms of the cost of energy (natural gas), this is the most economical way to heat a garage, but it is accompanied by hidden costs:

• preparation of design and permitting documentation;
• payment for the work of licensed gas equipment installation specialists;
• costs for ventilation and removal of combustion products;
• costs for routine maintenance of the boiler;
• possibly the necessary construction and subsequent maintenance of the chimney.

Alternatively, to heat the garage you can use infrared gas heaters, heating panels, convectors that consume liquefied propane and butane in cylinders - this eliminates the need to go through the authorities, but adds the problem of providing fuel.

Features of gas heating:

• 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.

Infrared heaters for home and garden

Infrared heating devices, which recently appeared on the market, are very quickly gaining popularity. They do not have most of the disadvantages characteristic of other models of electric heaters. These economical devices, just like other heaters, can be of several types - wall-mounted, floor-mounted, ceiling-mounted.

In addition to such valuable quality of infrared heaters as heating objects, furniture and walls, rather than air, they also have the following:

• the ability to quickly warm up the room;
• Fire safety;
• during their operation, the air in the room does not dry out;
• noiselessness;
• devices can be mounted on any plane - walls, floors, ceilings;
• low power consumption.

Infrared heating devices can be with ceramic panels or micathermic, and are the most economical heaters for the home. The effectiveness of micathermic devices is associated with the presence of non-metallic plates coated with mica. These devices easily heat objects located at a considerable distance from them, and remain cold, which characterizes them as quite safe. The price of these heaters is much higher than other types. But it is justified by their compactness, installation capabilities in various places, and ease of rearrangement.

Modern ceramic heating devices operate very efficiently. Many buyers recognize them as the best heaters for the home.

Due to the high heat transfer of ceramic heaters, they do not consume much electricity and operate as follows:

• based on convection, when flows of cold air pass through the heating element and move further, thereby increasing the air temperature in the room;
• using infrared radiation, which heats not only all objects in the room, but also the room itself.

The most relevant, economically, is the ceramic panel. Externally, the heater resembles a stove. The heating panel is hidden in a steel box, which has energy-saving and heat-conducting properties.

Many manufacturers have begun producing heating devices with combined infrared-convective heating of the room. Due to the synergistic effect of double heating, such devices can easily and quickly create comfortable conditions for a person not only in a city apartment, living rooms of a country house or country house, but also in utility rooms not intended for living.

Additional actions

Technology is no smarter than humans. No device can replace your ingenuity and will not take responsibility for your comfort and health. Therefore, in order for the heater to operate correctly while maintaining efficiency, and for greater savings, it is worth taking some actions.

• Insulate the walls. Drywall + foam works best.
• Install plastic windows. Tightness is the basis for heat preservation. Through old wooden frames, 50% of the heated air will be blown out.
• Hang interior doors if you use a convector. This heater has one of the highest efficiency in confined spaces - so use it to its full potential.
• Combine convectors into a single heating system. This way you can control the heating and save electricity.
• Buy a device with an electronic thermostat. It is reliable, durable, silent. The error in temperature readings is no more than 0.1 degrees. This helps maintain optimal heat with minimal energy consumption.
