Gas boiler for a garage: types and characteristics

Advantages and disadvantages

Main advantages:

• almost instant heating of the garage;
• the equipment is mobile and compact, it can be moved around the box, installing it in the right place;
• not affected by power outages.

Among the disadvantages are:

• when using natural gas, a lot of approvals and inspections of gas equipment and pipe connections to the garage will be required. And the high price of the design documentation will make you think about the feasibility of this method of heating the box;
• devices powered by liquefied, bottled gas are explosive;
• thermal energy is not accumulated, so it will be necessary to equip the surfaces with protective screens with reflective surfaces. In this case, the warm air, reflected, will fall down and heat the box, and not heat the floor slab;
• When using open combustion stoves, there is a high risk of headaches and throat diseases. Fire burns oxygen and makes the air dry. Therefore, you will need to install a forced ventilation system and install a humidifier.

Modern gas furnaces are designed with disadvantages in mind. Catalytic-type gas furnaces do not burn fuel during operation. For the best and responsible choice, you will need knowledge of the types of garage heating devices.

Example of a gas heater for a garage

Gas garage heating

If you nevertheless decide to do autonomous gas heating of the garage, then you can use both stationary and mobile equipment:

Stationary equipment

This type includes various gas stoves and boilers, the installation of which in a garage requires permission from the relevant services. The main requirement is the possibility of building a special boiler room, where the gas boiler itself will be located, intended for heating the garage. It is prohibited to place gas equipment in the same place as a car.

When purchasing and installing, certain costs will be required, but they are higher in comparison with electric heating equipment or, especially, stove heating. In the future, all costs for a gas stove in the garage will be fully justified and the entire system of such heating will cost much more profitably than other types of heating.

Mobile gas equipment

If you are not planning a whole gas stove for the garage or there is no need for constant heating of the garage, then you can completely avoid purchasing and installing expensive gas appliances and laying pipes. Then you can completely use gas cylinders and other heating units that can be connected to them. Heating a garage with bottled gas is an excellent option, unless, of course, you want to open a permanent workshop or production facility. You can calculate gas consumption by knowing which heating device will be used. Also, taking into account the operating mode and power of the devices, it is possible to calculate the most suitable volume of gas cylinders.

It is better to store gas cylinders in a metal cabinet, additionally insulated from freezing, and it is advisable that the cabinet is located above floor level. Because the gas in the cylinders is heavier than air, and if there is a leak, it will be easier to find the problem.

Heating with a gas gun is the most effective method of quickly heating the air in the garage. Powerful appliances can increase the temperature in a room in a matter of minutes. Less powerful ones are used for local heating of a separate part of the room or in a repair area. For the same purposes, gas convectors are also used to heat the garage. They operate on liquefied bottled gas and differ in their positive thermal power.

Power is roughly calculated using the following formula: divide the area of ​​the room by ten: S/10. It is also worth considering the fact that the higher the useful power, the higher the gas consumption will be. Most gas convectors additionally have fans (powered by electricity) that promote faster air circulation.

You can also use a gas burner to warm up the garage. As a rule, it usually involves the use of mini-cylinders with gas, since this device serves more for cooking than for heating. Do-it-yourself gas burners can be connected via a reducer to standard cylinders, but this should be done with caution. Each homemade gas burner involves receiving heat from an open fire, which in itself is not very safe. The burner itself can be directly part of a more powerful heating device.

Kinds

These devices are divided into:

1. Infrared heater equipped with a ceramic burner. This is an effective method, in which the burner gives off heat not only to the air, but also to the objects surrounding the stove. Heat accumulates and gradually enters the room.

2. Gas convector. This device burns natural or bottled gas in a closed firebox. For better operation, you will need to make forced ventilation to supply air into the firebox, necessary for combustion and exhaust gases out into the chimney. This work will avoid the combustion of oxygen and a decrease in air humidity.

3. Heat gun. Such equipment can quickly heat a room, but cannot accumulate heat. This option increases fuel consumption, so the guns are suitable for heating garages with natural gas or for short-term heating of a room.

4. Modern devices operating on the principle of gas oxidation with oxygen and the release of a large amount of thermal energy. The equipment is not cheap; expensive materials are used as catalysts. Advantages - light weight, ease of operation, but you will need to take care of the alarm system or fire extinguishing.

Advantages and disadvantages of IR

Garage IR heater equipment, technical indicators and features of use have specific advantages and disadvantages.

Advantages:

• connecting equipment does not require large financial investments;
• the basic package consists of the necessary parts for installation;
• simple connection of an electric emitter;
• installation of gas equipment may require obtaining the necessary permit;
• the possibility of separate zones of the room, rather than the entire garage;
• modern models are protected against overheating of the surface and fire in the event of a fall.

Minuses:

• the power of household appliances is much reduced in order to obtain favorable heating conditions;
• the high cost of the device and the large number of Chinese counterfeits that fill the climate system market.

The IR heating system has no analogues. Compared to a standard heating radiator, they allow you to get instant heating even in a cold building. High efficiency and almost no significant disadvantages explain the popularity of infrared emitters.

Criterias of choice

It is important to choose a gas stove for a garage taking into account the main characteristics. Let's look at them in more detail.

Power

This characteristic will allow you to save not only on the purchase of the optimal stove option, but also during operation. A powerful stove will heat the room faster, but gas consumption will also be higher. A low-power stove will not be able to heat the room. Therefore, it is important to know even approximately the required power of the equipment to heat your garage.

You can calculate this characteristic yourself. To do this, you will need to determine the volume of the entire room and the cubic capacity of the gate. Multiply these values ​​by the coefficients for the materials from which the garage itself and the gate are made. The resulting result will be the approximate power of the heating unit.

Material

This characteristic affects the longevity of your stove. When purchasing, you will need to familiarize yourself with the thickness and grade of steel of the body and firebox. When using structural steel, the thickness of the firebox sheet should be from 6 mm. It is better if heat-resistant steel or alloys were used in heat guns or convectors for the production of the body and grilles.

Alloy steels with a high content of chromium, silicon, and molybdenum are the best option for the production of parts exposed to high temperatures. Another option for a material that is not exposed to aggressive environments is stainless steel.

Winter summer

If the use of heaters is planned to be short-term and during the warm season, there is no point in buying expensive, powerful equipment. Small heat guns or convectors or a homemade stove that burns gas in a closed chamber will help here.

For winter and low temperatures, you will need to purchase a powerful gun or several infrared heaters and install them throughout the room. At this time, the efficiency of technology is an important factor.

Price

In this matter one should not go to extremes. You can’t try to save money and buy low-quality Chinese equipment for pennies and throw it away after a short time. But you shouldn’t buy an expensive, powerful heat gun from leading manufacturers to heat a small garage during short visits.

It is much more important to select equipment based on price and quality ratio. This is the only way to purchase good, productive gas-powered equipment for your box.

Other factors

Other factors include:

• level of environmental safety. The equipment should not harm consumers by releasing toxic substances when heating low-quality materials. Therefore, when purchasing, be sure to check the quality certificate;
• quality of garage stoves. Here you can determine who made the technique simply. Run your hand along the edges of the metal and if you find burrs, it means that your stove was not made in production. Pay attention to the quality of the paint coating, it will immediately show the experience and qualifications of the manufacturers;
• Pay attention not to the brand, but to the characteristics of the heaters. You will have to overpay for the name of an advertised company, although even the BOSCH brand is produced in 300 countries around the world. Before going to the store, go to forums on the Internet, here you can get reasoned and truthful advice.

Best models

Based on customer reviews, we have compiled our rating of the best models of gas furnaces for the garage.

The simplest designs can be made independently from scrap materials.

Do-it-yourself gas stove for the garage

A gas furnace for a garage is manufactured in several stages.

Before starting work, we will prepare the necessary tools and materials.

Materials and tools

In addition to a set of metalworking tools and metal scissors, you will need to prepare:

• sheet metal, thickness 0.5-0.8 mm;

• mesh - chain-link, for making gratings;

• old sieve;

• purchase a gas burner with a safety valve at the market or in a specialized store;

• gas cylinder;

• fittings for connecting the cylinder to the burner.

Manufacturing instructions

A fine sieve must be prepared according to the size of the future oven:

• after that, mark a circle on a sheet of metal, placing a sieve on it. On the sheet, in the form of a scan, along the edge of the circle you need to mark the sides. To do this, mark out a rectangle so that the length is enough to encircle the sieve and the round bottom of the future stove;
• cut out the reamer using metal scissors. Try to cut carefully so that there are no large protrusions or irregularities;
• We place the burner in the back and mark the mounting points. Drill holes and fix the burner;
• Having made a small flange, we connect and fasten all the parts together with rivets. A drilled plate is fastened with rivets on top of the sieve, on which a netting mesh is riveted with small steel plates;
• using a riveter, 2 legs of the required length are attached;
• We screw the hose from the gas cylinder to the burner valve and turn on the gas. After checking the tightness of the connection points, you can make the first start-up of a DIY gas furnace for the garage.

Requirements for garage ovens

It is important to remember that the garage, although a secondary structure, usually made of bricks or blocks, is still a fire hazard. That is why, first of all, fire safety rules must be taken into account here.

What exactly should you pay attention to?

• Fireproof foundation;
• Reflector installation;
• Maximum distance from the furnace to the storage location of fuels and lubricants;
• Correct selection and installation of the chimney.

These are just the main requirements. There are still many little things that a fire inspector can pay close attention to. They will have to be corrected during the operation of the gas appliance.

Now let's talk about what the garage stove will work on. Since we are talking about do-it-yourself devices, it is also worth using an energy carrier that will not “hit” your financial situation too much. Of course, the ideal option is when a gas pipe is connected to the garage. But in the city this is unlikely. But in a private house this option is very good.

1. Firstly, gas is budget-friendly.
2. Secondly, in terms of operation, a gas stove for a garage is very convenient.
3. Thirdly, gas reduces risks associated with fire safety. Thus, by installing a safety unit on the device, such an oven can be safely used.

Installation Rules

If a pipe with natural gas is used, the process of approval and acceptance of the work performed will be delayed. You will need to make a forced ventilation system in the room, install a large stove on a separate foundation, slightly recessed into the floor. Let's add to this the purchase of a gas meter and constant visits from a technician with inspections and payment for them.

But the basic dimensions for installing fire-hazardous equipment in rooms with flammable surfaces are the same for all types and types of stoves. Size to the floor made of flammable materials from 140 mm, to an unprotected wall made of wood from 700 mm. Distance to ceiling from 1000 mm. In the garage, you will need to make ventilation cavities in the walls and possibly install a chimney when using a large gas furnace or boiler.

When installing wall-mounted equipment, fasten it only to solid walls; fastening to thin partitions is strictly prohibited. The stove or convectors must be installed in safe places and not interfere with free passage and access to heaters.

The oiled floor under the stove will need to be insulated with a sheet of fiber board or metal.

Heating a garage: the most economical way, what to choose

If the outbuilding is located next to the main building, gas heating is often used. In this case, the heating system can be connected to an existing one in the house.

To heat your garage yourself economically, you can use the heating option using different types of solid fuel raw materials. Which can be used as firewood, peat, coal and diesel products. At the same time, you can save on resources, but it is important to think about the storage of raw materials.

A simple potbelly stove can adequately heat a small room

For your information! A simple solution is a gas convector. In such equipment, heat circulation occurs due to convection. The device is connected to a cylinder, but it will need to be refilled every few days.

Features of operation

It is important before using gas stoves in the garage to make sure that the ventilation is working properly and that there is no gas pollution in the room. The valve on the gas cylinder or on the stove must be closed after each switching off of the equipment, even if it is equipped with its own shut-off valves.

Therefore, having opened the gas, we light the burner flame. If a cannon is used, the fan is turned on before the fire is lit. A reducer must be installed on the cylinder, which protects it from backlash and regulates the gas pressure.

Otherwise, the operation of a gas furnace is similar to other types of furnaces. The main thing is to be responsible and careful about the maintenance and care of equipment and your garage will always be warm.
