How to choose a heat gun?
Heat guns are heating devices that consist of at least two parts, a heating element and a fan, which creates a directed heat flow of air. The high power value of such devices (at least 3 kW) and considerable dimensions make it possible to successfully use them for rapid heating of any large-volume premises - hangars, production and storage facilities, construction workshops, workshops, shops, garages, etc. One of the main disadvantages of thermal guns is their mass - from 7 kg. Both portable and stationary models are available.
The design of the heating element depends on the type of device - it can be a spiral or heating element. To protect it from chemical and mechanical damage, as well as to ensure safety during operation, a durable metal case is used. The fan is also located in the same case.
The main advantage of heat guns is the high speed of heating the air in the room - this process takes a few minutes. Combined with a decent economy, these heaters are one of the very best winter heating tools.

They allow not only to quickly warm up the entire volume of a large room, but also to maintain the required temperature level in the future. They are mainly used in construction, for drying various materials and premises.
Also, this type of heat gun is used to replace centralized heating in the event of an emergency. For such cases, several layouts have been developed. For example, when a gas heat gun is in the open air, the flow of hot air is transferred to the heated room by means of a flexible hose. If the device is supposed to be placed indoors, then you should take care of a reliable system for removing combustion products.
Gas-fired heat guns are quite compact, lightweight and more economical, since electricity is consumed only to rotate the fan. To heat the air, they use the combustion energy of liquefied bottled (propane-butane) or main (natural) gas. When choosing a heat gun, the first thing to do is to make sure that it contains a burner flame monitor. It will also be useful to check the operation of the protective system that ensures the safety of the user.

Air heating in them is carried out by converting electricity into heat. These devices, unlike gas ones, do not burn oxygen and do not emit combustion products. Powerful models require a three-phase power supply.
For ease of use, electric heat guns have a stepped power regulator. It allows you to set the required temperature for heating the air. The advantages of these devices are their small size and high convenience and safety. Therefore, they find the widest application in everyday life - heating residential and office premises.
The most efficient representatives of heat guns are of the diesel type. Their power can reach 200 kW. These devices, as well as gaseous ones, emit combustion products, and even have a relatively high cost. Due to their high efficiency and reliability, they are used for heating air in rooms with a very large internal volume.
