Garage heating system on the exhaust of a gas boiler from the house

Gas garage heating overview of different types of equipment

Heating a garage space is a topical issue for many car owners. This is not only a manifestation of caring for your favorite vehicle, but also a great way to organize a workshop, an additional area for storing things you need in the household. Gas heating of the garage has become widespread today. If the garage is located on your site so that it can be connected to the main gas pipeline, then the issue of heating is practically solved. Garage heating can also be autonomous; for its arrangement, you can choose both portable and stationary equipment.

Advantages of gas heating in the garage

• Low cost compared to electricity;
• Economical consumption - to maintain the optimal temperature in the garage, you do not need large volumes of fuel;
• The possibility of using gas in cylinders for arranging autonomous heating;
• Gas is a natural fuel that burns completely and does not emit harmful substances into the air.

However, there are certain difficulties when installing gas heating:

• The acquisition of the necessary equipment will require a solid initial investment;
• Connecting gas installations on your own is prohibited by law, for this you will need a specialist;
• There are safety requirements for such equipment that must be met.

Stationary gas equipment

Stationary gas heating in the garage - boiler

This includes special boilers, to which a system of water pipes is attached. To install them, you will need permission from the gas service, as well as the arrangement of supply and exhaust ventilation. Since the garage is considered a fire hazardous object, the boiler is taken out to a separate room with a size of at least 4 sq.m. with walls covered with non-combustible materials. According to the norms, the boiler room must also have a door with a width of at least 800 mm.

The advantage of using a stationary boiler is the possibility of full-fledged, round-the-clock heating of the building. In this case, you do not need to control the operation of the equipment. At the same time, installing a boiler will require significant investments from you, which will pay off only in the long run. This option should be considered by those car owners who plan to open a workshop or a small production in the garage.

Mobile gas equipment

In this case, we are talking about non-permanent (periodic) heating of the garage using various heating devices that are powered by natural or liquefied gas cylinders. These can be heat guns, burners and convectors.

Gas guns are powerful heating devices with a small burner, the heat from which is quickly distributed around the room with the help of a fan. They are convenient to use for short-term, as well as local heating of the room. The disadvantage of the device is the release of combustion products into the air, which quickly accumulate in the room. Thus, you will need the arrangement of high-quality ventilation.

Gas convectors can be equipped with a fan, which promotes the rapid circulation of heated air masses, as well as a thermostat. They are compact, inexpensive, safe to use, compatible with LPG systems. But, like gas guns, they require ventilation or a special chimney.

The simplest portable devices are burners. They are connected to both large cylinders and mini-cartridges with gas. Due to their open flames, burners are considered unsafe for permanent use in a garage.

Features of heating a garage with gas from cylinders

According to fire safety rules, gas cylinders should be stored in a special cabinet made of metal. It should be located away from flammable objects and heating devices. Make sure that the cabinet is located above the floor line - so if there is a gas leak, you can quickly notice and fix the problem.

Heating the garage with gas from cylinders in a special cabinet

The choice of gas equipment for the garage depends on the frequency and purpose of its use, the financial capabilities of the customer. On the one hand, installing a stationary boiler is not cheap, on the other hand, heating with cylinders causes a lot of inconvenience. During severe frosts, cylinders have to be changed every 2-4 days, which also translates into a considerable amount. And don't forget about garage fire safety.

Hello everyone! Sandwich garages are my passion. I can talk about them day and night. I can tell =)

Choosing the right gas boiler

It is possible to purchase a suitable gas boiler on your own

It is worth paying special attention to each component of the equipment. In particular, this applies to the body material itself, the chimney (if any), as well as the ignition system.

In addition, you need to find out which option for connecting to gas takes place.

The most popular devices are boilers made of cast iron and steel. If choosing between the two, preference should be given to the latter, since cast iron is considered a fairly heavy metal. A convenient boiler is one that has an electric fuse installed.

Particular attention should be paid to the chimney. Since the products of combustion are aggressive, it is necessary that this part be made of durable material.

Alloy steel is considered ideal. However, there is equipment where there is no chimney as such (the device is equipped with fans).

Choice of energy carrier

Gas heating will be the most convenient and rational solution, however, this method is only possible if the garage is located next to a private house, when the garage heating is combined with the heating of the house itself and radiators are simply installed in the garage.

Another method that is quite common is heating with solid and liquid fuels - coal, peat, wood, mining, diesel fuel.

This method is one of the cheapest, but, first of all, it is necessary to solve the problem of fuel storage.

Not everyone can afford the electric heating method, but still, some motorists choose this type of heating for their garage.

Preparing for installation

The gas boiler must be installed separately from the garage a room of four square meters and with a ceiling height of more than two meters. The width of the door must exceed 80 centimeters. In addition, the room must be provided with good ventilation and a window that will become a natural source of light during the daytime. The walls in the room must be finished with non-flammable materials.

When arranging a chimney, you will need to bring the pipe one meter above the level of the roof of the garage

It is also worth paying attention to the number of bends on this pipe. They should be as small as possible so that the substances released during combustion do not settle on the chimney sections.

Usually, a pipe with a diameter of 130 millimeters or more is used to equip the chimney.

The place of the roof where it will be connected to the chimney must be protected with refractory material, such as galvanized steel or asbestos board.

Electric heating

The simplest and relatively affordable method is electric heating, for the arrangement of which it is enough to purchase the appropriate equipment. A wide variety of options, mobility and compactness are the main advantages.However, the costs will directly depend on the established tariffs for electricity.

Before arranging electric heating, you must select the most suitable device:

1. Electric inverter
2. Infrared heater
3. heat gun

Among the varieties of electric heating, the most effective is the inverter or "heater". There are a huge number of models on the market that are installed on the floor or hung on the wall. They are quite compact, but at the same time very productive.

The approximate cost of an electric inverter is from 10 thousand rubles.

A compact and efficient solution is the installation of IR heaters - a fairly powerful and productive device

However, paying attention to the rapid heating of the room, they can not cope with large areas. The negative aspects are also the high energy consumption and the associated installation costs.

The average cost of an infrared heater is from 4 thousand rubles.

Heat guns are considered compact, productive and convenient, capable of heating a garage space as soon as possible. They consist of a heater and a fan dissipating heat into the environment. However, to connect such equipment, it is necessary to have a single-phase network with a large cross-section of the wire being laid or a 3-phase network (the latter is preferable).

The cost of heat guns - from 5 thousand rubles.

What to look for when choosing

The decisive factors when choosing a gas boiler are:

• the material from which its body is made;
• ignition system;
• the presence or absence of the need to install a chimney;
• features of indoor installation;
• way to connect to gas and water.

Material

Most often in the gas equipment market there are cast-iron and steel models. Cast iron is a high-strength and durable material, but its disadvantage is its high weight. Therefore, it is preferable to use steel heaters.

Manual or electric ignition?

Boilers with an electric fuse are much more convenient to use. When installing them, the following conditions must be met:

1. uninterrupted power supply;
2. separate connection to the power supply network;
3. grounding.

The solution to the first problem is the installation of an electrical stabilizer that suppresses power surges.

Varieties of boiler equipment

The chimney oven has an inlet temperature of about 120°C. The combustion process of gas takes place with the formation of substances such as carbon monoxide, hot steam, sulfur dioxide, etc. All of them are removed from the garage using a chimney. At low ambient temperatures, vapors condense on the walls of the chimney and flow down.

Combustion products are quite caustic substances, therefore, increased requirements are imposed on the material of the chimney. For the construction of the chimney, it is recommended to use alloy steel pipes, as well as to carry out their thorough thermal insulation.

Garage heating can also be carried out by such boilers that do not need chimney equipment. They have built-in fans. Also, condensing boilers with a pulsed gas combustion mechanism are gaining popularity.

The essence of the problem

At its core, any garage is a utility room (usually detached) of a warehouse type, but in which there is a car and substances belonging to the flammable category. These circumstances cause the emergence of increased requirements for fire safety. Naturally, the question arises, is it possible to place a boiler room in a garage at all?

Solving this issue, you should understand what a boiler room is and why it is installed. Several tasks are possible.Most often, the term garage boiler room means a boiler for heating only the room itself, but sometimes the boiler room in the garage acts as a source of coolant for heating a private house. If in the first case a small standard boiler of various types is used, then in the second case rather large areas and special permission are needed.

In any case, a garage with a boiler room is not prohibited by regulatory documents. At the same time, it must meet all technical and fire safety requirements. The need to draw up a project and coordinate it with the relevant organizations depends on the type and capacity of the equipment, the type of fuel consumed and connection to centralized highways.

How to make everything perfect

In order for the garage boiler room not to cause complaints from regulatory authorities, the following basic principles should be taken into account during its installation:

1. The room must be equipped with efficient and reliable forced-type ventilation. The removal of combustion products must be carried out through an air pipe, the outlet of which is located on the roof (at a normalized height).
2. All fire safety regulations must be strictly followed. At the same time, the number of boilers in the room should not exceed 4 pcs. with a total power of up to 190-210 kW.
3. The boiler must be at least 100 cm away from the garage wall.
4. The minimum size of the garage in which the installation of boilers is allowed is 6.5 sq.m with a height of at least 2 m.
5. A heat-resistant solid base (foundation) must be built on the floor under the boiler. Flammable materials must not be placed around the boiler.
6. Connection of communications must be carried out professionally, taking into account all norms.

Increased requirements apply when using gas. When a gas boiler is installed in the garage, coordination is necessary already at the design stage. A permit must be obtained for the diversion of the gas pipeline and gas consumption standards must be established. Installation of gas boilers must be carried out in strict accordance with the regulations: SNiP 31-02-2001, DBN V.2.5-20-2001, SNiP II-35-76, SNiP 42-01-2002 and SP 41-104-2000.

We organize a boiler room in the garage

Next, we propose to find out how the organization of the boiler room in the garage is carried out.

Accommodation layout

It is better to install a gas boiler in a separate building, the area of ​​\u200b\u200bwhich is at least four square meters. There is a requirement for ceilings - they must be more than two meters. As for the width of the door, its size should be 80 centimeters and above. In addition, the room should be ventilated and have a window that would provide natural light in the room during the day.

The boiler room is recommended to be done at a relative distance from the residential building for several reasons. Firstly, so that the noise from work does not interfere with the household. Secondly, the boiler room is classified as a fire hazardous facility.

Preparatory work

First of all, the walls in the garage must be finished with heat-resistant material. If it is necessary to install a chimney, the pipe is led out above the level of the roof of the garage, approximately one meter. In addition, it is worth considering how many bends are present on the pipe. So, the smaller this figure, the better, since otherwise the substances that are released at the time of combustion will begin to settle on the sections. As a rule, to equip the chimney, a pipe with a diameter of 130 millimeters or more is taken.

The place of the roof where the connection to the chimney takes place must be protected with refractory material. Take something like galvanized steel.

Arrangement of ventilation

To ensure the safe operation of the boiler room in the garage on your own site, you will need to take care of the presence of a solid ventilation system that can cope with the removal of harmful gases from the room.

The fan power is calculated according to the following formula:

• M – fan power;
• S is the building area;
• H is the height of the building.

This formula includes the moment that the air in the room is renewed, on average, in 12 hours, and the minimum power reserve of the equipment is estimated at 30%.

Installation of a heating boiler in the garage

In the garage, wall-mounted or floor-mounted boilers are more often purchased. The equipment is installed on a brick (concrete) stand.

The boiler is fixed horizontally and vertically. Walls and other objects in the room should be at a distance of 30-50 centimeters from the device.

Connecting the appliance to gas and water

After the installation work is over, the boiler is connected to the gas and water supply. Water is brought to the equipment standing on the floor from above or to the side. In the version with a wall-mounted boiler, communications are led to the transverse side.

Also, the remaining components of the device must be installed. In that situation, if the room does not need to purchase an electric pump, the pipes are laid with a slope of five millimeters (one meter in length). Otherwise, there will be difficulties with the circulation in the heating.

System startup and testing

After the completion of the manipulations to connect the device to the water supply system, the boiler is started in order to check the tightness of the connections. In the event that the test run ended positively, the boiler is connected to the gas pipeline.

Fuel boilers

The options discussed above provide for connecting the equipment to centralized gas or electric networks. What to do in the absence of highways and unreliable power supply? A mini-boiler room in a garage can be based on liquid or solid fuel boilers that do not depend on the supply of centralized energy. The following settings stand out:

1. Solid fuel boilers. A modern boiler of this type can be safely installed even in a room such as a garage. The installations are versatile, i.e. they are able to work on coal, peat, wood, even on construction debris and straw. It is considered optimal to use special combustible briquettes based on compressed coal dust and other components. Fuel consumption occurs in a minimum amount, which is ensured by its complete combustion. Boilers operate on the pyrolysis principle, which gives a fairly high efficiency.
2. Liquid fuel boilers. They lay down an important principle of economy. They can be operated on used engine oil. This makes it possible to obtain cheap fuel and at the same time solve the problem of waste disposal.

The main advantage of fuel boilers is the absence of the need to obtain permits and the availability of fuel. An important disadvantage can be considered the presence of a significant amount of combustion products. To remove them, you need a reliable chimney, the pipe of which must go to the roof.

Heating with solid fuel

When other methods are not suitable for some reason, you have to stop at heating the garage with solid fuels (wood, briquettes, coal, etc.). There are a lot of options, but the simplest and least expensive is the installation of a small potbelly stove. For its operation, there is no need to supply gas or a reliable electrical network.

It should be noted that solid fuel stove heating is an excellent solution for small spaces. In a spacious garage, its operation will be ineffective. You will also need to manually regularly throw logs or briquettes into the furnace.

The classic potbelly stove can be replaced with a more complex and expensive design - the Buleryan stove. It is considered the most reliable and productive, but its construction with your own hands can cause a lot of trouble.

How to make buleryan with your own hands, see here

When purchasing a solid fuel boiler, you should follow some rules and features of its operation:

1. Do not pour liquid fuel into the furnace, otherwise it will quickly burn out
2. To light a fire, it is recommended to use paper or special kindling.
3. It is necessary to think about arranging a reliable chimney, which will be insulated with high quality, it is recommended to clean it regularly
4. The installation of a heating solid-state boiler must be carried out exclusively on a monolithic base
5. Surfaces in the vicinity of the boiler must be protected from the possibility of spontaneous combustion.

Varieties of boilers

First, it is worth considering what types of boilers exist.

1. Gas boilers - it is advisable to purchase when in the utility room it is possible to drain the pipe from the gas main. This fuel is considered the most budgetary. In the form of a heat carrier, a liquid acts, which is heated by the boiler. Heating is provided by the convector method, using a fan.
2. Electric boilers - it is advisable to mount in a room where the heat carrier is heated by electricity. The principle of operation of such a device is that the heating of the liquid in the heat exchanger is carried out thanks to electric heating elements.

Location of a gas boiler house in a private house, distances

The main condition is compliance with the thickness of the wall connecting the garage and the boiler room, everything else is optional

It is also important to withstand the time period, not immediately after the foundation to start building walls, but to wait a year until the foundation sits down. This is necessary so that there are no cracks in the walls.

Today, construction sites are often customized, but in vain! - fraught with consequences

Since gas heating is one of the cheapest, the best option for heating a garage is to equip just such a system.

Before installing a gas heating system, the following points must be considered:

since the gas is explosive and flammable, it must be handled with great care. This means that it is necessary to choose high-quality gas appliances and entrust their installation to professionals;
gas heating is best used if the garage is attached to the house, has a gas pipeline nearby, or if you need to provide heat to several garages at once.

Garage heating with gas

It will be very practical and very economical to use gas for heating a garage room. Together with them, special heat generators work. In this case, methane, butane or propane, classic natural gas, can be used.

To independently assemble the gas heating of the garage with your own hands, you should take into account several significant features of the work:

1. The gas cylinder must be installed in a special, securely insulated cabinet.
2. Even if the room is small, you will have to try and take a protected corner to install the required equipment.
3. If the garage will be heated infrequently, other options should be considered.

One of the advantages of gas heating is the availability of equipment on the market and the cost of the coolant, which is one of the cheapest types of fuel.

A word about fire safety

Equipping garage heating with your own hands, you will definitely have to take into account a very important requirement - to follow all safety rules. Any equipment is a fire hazard and can cause serious consequences.

The most important requirement is the reliable protection of all nearby surfaces. This is especially important when passing through a wall or roof of a chimney.

To eliminate its contact with building structures, it is recommended to make a special sleeve based on mineral wool.Wooden or plasterboard areas will have to be protected with a metal shield. All gaps are compensated with an asbestos cord.

Other tips to consider:

• If heating boilers are used. it is necessary to close the draft control damper only in those cases when the fuel has completely burned out and smoldered
• Do not keep flammable substances in the garage, especially if they are located near heating equipment
• Be sure to place a fire extinguisher or other means of extinguishing fires in the room
• If the heating system is constantly running or the garage is located in the immediate vicinity of the house, it is recommended to equip a fire alarm
• Do not dry any things on heaters, especially various rags that could come into contact with flammable liquids.
• Storage of gas cylinders is allowed only above the level of the floor surface
• It is not recommended to leave the heating on at night.

Connecting electric heaters

It is most carefully and competently necessary to think over heating with electric heaters. If their power is too high, the wiring and the meter are not able to cope with the load - you will have to opt for weaker equipment. You can lay new wiring, but such a conversion of the garage will be too expensive.

Consider some of the features of connecting electric heaters in a garage room:

1. The minimum recommended wire size is 2.0 mm, with copper preferred
2. It is undesirable to use a portable cable to connect electric heaters. If necessary, its length should not exceed 5 m
3. Single-phase electrical wiring is able to withstand the connection of an electric heater with a power of up to 2.5 kW. Parallel connection of 2 or more devices will cause a voltage drop to 170 V, which can be very dangerous

The arrangement of a heating system for a medium-sized garage room intended for one car starts from a modest 5-6 thousand rubles and can reach a couple of dozen. Each of its owners must evaluate the considered options based on the needs and wishes.

To reduce the cost of operating the equipment, part of the money should be spent on insulating the walls and ceiling in the room. Work should be carried out outside, otherwise the heat-insulating material may cause a fire.

It is necessary to take care of the absence of holes and cracks through which precious heat will flow. Roof insulation is best done with expanded clay, while taking care of reliable waterproofing. For walls, foam plastic up to 10 mm thick or mineral non-combustible wool is used.
