Because the heat gun retains the title of one of the most powerful devices for space heating, when searching for the optimal model, one must largely focus on the “combat capability” of the device. We have prepared some rules choose a heat gun.

Rule one: area determines power
The power of the heat gun is determined in the same way as the performance of the convector. To do this, the area of u200bu200bthe room where it is planned to use the fan heater is multiplied by a hundred times. In other words, it takes 100 watts to heat each square meter of a room.
Thus, for a large office with an area of 200 square meters, it is necessary to buy a heat gun with a capacity of 20 kW, and for a small room occupying 12 residential “squares”, a device generating 1.2 kW will be quite enough. To more accurately calculate the required power of a fan heater, you will need to take into account the difference in temperature inside and outside the house, as well as the thermal insulation coefficient. In addition, the number of window and door openings, as well as the height of the ceilings, play a role.
Rule two: the longer, the bigger
As the main source of heating, as a rule, stationary heat guns are used. Although they are bulky, they are much more productive. At the same time, they allow you to achieve the greatest savings in resources when heating a room.
At the same time, mobile heat guns are usually used for temporary heating. They are convenient, easy to operate and have a capacity of 2 to 30 kW, which is enough to heat even spacious rooms.
Rule three: avoid combustion products
In addition, a choice must be made between a direct and indirect heat gun. In the first case, combustion products enter the surrounding air, so such devices are suitable either for open construction sites or for non-residential premises where there are practically no people. Otherwise, you need to think about additional ventilation.
The indirect heating fan heater includes a system that prevents combustion products from entering the room. Therefore, such a device is optimally suited for residential premises. So before you buy a heat gun, you need to decide in what conditions it will be used.
Rule Four: Safety First
The heat gun must be resistant to various damages. The guarantor of this is the durable case of the device. In addition, fan heaters must have overheating protection, which is triggered by a temperature sensor as soon as the device body reaches the limit temperature, as well as a function to turn off the device when it capsizes.
Rule Five: Harmony Requires Silence
The noise level of powerful heat guns can create some discomfort. To avoid it, before you buy a heat gun, you should make sure in advance that the noise level emitted by it is within reasonable limits. So, the noise level up to 40 dB is considered normal for such devices. At the same time, if the heat gun is planned to be used for a construction site, then the noise level achieved by the device fades into the background.
Rule six: exclude by smell
Some models of heat guns can burn air and, therefore, create an unpleasant odor that quickly spreads throughout the room. The more suitable for high temperatures the heating element is equipped with the device, the less likely it is that the heat gun will create discomfort. In particular, devices equipped with ceramic heaters are considered more advanced in this respect.
