Features of the selection and installation of a heat gun in the garage

As a rule, heat guns of various layouts are used to dry the facilities under construction, to heat the production capacities of a wide profile, because they are powerful high-performance machines. But lately, many manufacturers have established the release of small-sized devices up to 3-5 kW, so that numerous motorists have a heat gun for the garage on the farm, with which you can quickly heat a small room.

Varieties of fan heaters

Equipment of this class is effective appliances for heating any room with the help of directional hot air. The efficiency of any heat gun reaches almost 100%. On sale there are such varieties of these products:

1. Electric - they work on heating only when there is a household power supply.
2. Diesel - the principle of action is based on the combustion of fuel in the combustion chamber with the subsequent heating of the air flow.
3. Gas - the principle is the same with the second option, but work on blue fuel, they are much more economical, because gas is cheaper.

Each species has its own specific features, advantages and small flaws.

Electric

Electric fan heaters have the following advantages:

• small dimensions make it possible to install the product in almost any room;
• full automatic control;
• silent operation;
• fairly high level of fire safety.

The disadvantages include the high cost of electrical energy. In addition, before installing the heat gun, it is necessary to check the wiring so that it can withstand the voltage from using such equipment. Devices must have overheating protection and automatics to maintain optimal constant temperature.

Diesel

These products have two types of heating: direct and indirect. In the first variant, the space is heated by an air stream in which there are combustion products, therefore it is necessary to install forced ventilation.In the case of indirect heating, the heat gun has a design that allows the combustion products to be removed from the combustion chamber through a special pipe that is sufficient to be connected to the chimney pipe or corrugated hose.

When a heat gun is selected in the garage, then it is necessary to consider and calculate all the options - take into account the volume of the room, how to make a conclusion of the products of combustion. Without a doubt, a device with indirect heating is much better than an analog with a direct heating method, when there is a danger of smoke from the entire room.

Experts include the following indicators as advantages:

• economical fuel consumption;
• heat guns of this class work on one tank refueling up to 14 hours;
• efficient heating of the garage of any size, even in two floors.

Disadvantages is cost of diesel fuel, and the smell of burnt diesel fuel remains unpleasant amber, which is not pulled out by any ventilation system.

Gas

Such guns with respect to diesel counterparts have several advantages:

• heat up the room much faster;
• heating of this type is many times more economical due to the lower consumption and cost of gas;
• there is a sensor that reads the concentration of carbon dioxide;
• automatic equipment controlling equipment overheating;
• propane or butane burns completely - it is not necessary to install a special diverting system, rather ordinary ventilation, which is in each garage.

There is one, but rather significant drawback: for the operation of the unit you need LPG cylinderwhich is quite not easy to get.

Tip! If there is no good ventilation in the garage, then all the options will not work for you, heating of the room will not be fully implemented due to frequent ventilation through the opening of the gate.

Choosing a heat gun

The main parameter when choosing a product is its power, the excess power will waste the meter, and the disadvantage is simply not able to provide sufficient heating for the garage. Experts by measurements and various experiments found that 10 m² Any private garage can be heated with 1 kW of heat output if the ceiling height is within 3 m.

Therefore, in the case when the area of ​​your premises is not more than 25 square meters. m, then you need to buy a device with a capacity of at least 2.5 kW, and given the extreme cold, it does not hurt to increase the power to 5 kW.It should be borne in mind that the power you will turn on the unit only in exceptional cases. What gun will suit you - decide for yourself.

Warming garage

Before installing any kind heater or fan heaterneed to take care additional garage insulation, especially the gate: the less heat is leaked, the longer the temperature in the garage will remain acceptable. Otherwise, the gun will work on the heating of the space surrounding the garage, that is, constantly.

Motorists should not forget that this room serves not only to shelter the car from weather cataclysms and thieves, but also for minor repairs and preventive maintenance. In especially cold weather, when you decide to thoroughly heat the room, condensate may form on the iron gates due to the temperature difference, which will negatively affect the metal.

The optimum temperature for high-quality storage of equipment in the winter is +5⁰C.

To insulate walls with high quality - use sheets of special foam or penoisol. The latter material is considered the most advanced type of insulation, it retains heat much better, it is very similar to polyurethane foam in thermal conductivity, but costs much less.

We insulate the ceiling in the same way, but for the gate there are several options:

• foam blocks - they keep warm and do not absorb moisture;
• extruded polystyrene - has even better rigidity, retains heat well;
• foiled polyethylene foam - characterized in that one side is covered with foil, used in combination with the first types of insulation.

During all the work on insulation it is necessary to solve the problem with better ventilation. For this you can do exhaust hood Directly from the interior of the garage - direct access to the outside. There will be enough cement-asbestos pipe of standard diameter and size.

Features of using guns

Today it is electric fan heaters of various types and devices that are considered the most popular for rapid heating of the garage, although the condition of the wiring leaves much to be desired. Therefore, fire inspectors like to visit such public places of use for drawing up acts of various violations.

It is no secret that the indirect cause of all the fires in garages is the improper use of heaters of various types, from homemade products to factory-made models. As a rule, the fault here is for 100% of users: before connecting an electric gun of any power, you need to consult with specialists of the grid. In addition, you need to follow certain rules of operation of products of any kind.

1. After acquiring the equipment, it is necessary to allow it to stay warm for at least 2 hours.
2. If this is a diesel option or a gas heat gun, purchased specifically for a garage insulated beforehand, it is better to make their first launch in the open air, in order to burn the factory grease.
3. Electrical option before switching on should be checked for the presence of condensate on the heating elements, as well as to inspect the garage wiring grounding.
4. A cannon working on waste oil is checked for the presence of foreign objects in the fuel tank before pouring fuel.
5. When using the chimney, it should have good traction and a minimum of bends.
6. Connecting a gas gun, check all connections for leaks, otherwise the first inclusion may be the last.

It is necessary to install the device only on a flat surface, the distance from the exit nozzle to walls or other objects is at least 3 m, on each side 0.5m is sufficient, and 1.5 m above.Such precautions are needed so that the discharge air flows freely throughout the room.

As for the cost: diesel devices are considered the most expensive: their price is from $ 200, gas is occupied by the average position at around $ 150, and electrical options from $ 50. Having made the right choice, you will forget about frozen hands and the engine not starting from cold for at least six months - it will be comfortable to work in the garage, even though there are severe frosts behind the gate.
