A heat gun is nothing more than a powerful fan that drives air flow through a heating element in a durable TEN casing. With the help of a heat gun, you can quickly reach the required comfortable temperature.
Heat guns differ in variety and purpose. The range of application of the equipment is very wide. In construction, a heat gun can be used to dry a room after plaster, varnish and paint, to dry flooded and damp basements, to warm up frozen soil, as well as bulk cargo. In addition, heat guns can be used to ventilate rooms if there is a mixing unit with an outside air intake. Thus, the heat gun is indispensable for the rapid heating of the room and, most importantly, safe.
When choosing a heat gun, you need to remember the required power of the equipment and the installation location.
You can use some mathematical calculations by calculating the volume of the room, the temperature difference and the required temperature inside the room. Then the dispersion coefficient is determined, which shows the degree of air dispersion for a given type of room. The highest dispersion coefficient will be for wooden and metal structures, the average value of the coefficient will be for rooms with one row of brickwork and windows without insulation; the dispersion coefficient will be even lower for a building with double brickwork, and the lowest dispersion coefficient is taken for buildings with waterproofing and roof insulation material.
Having received the necessary parameters, it is possible to calculate the minimum thermal power of heat guns in kilocalories per hour, which is required for a given room. By converting the obtained value into kW, it is possible to determine the minimum power of heat guns, regardless of what kind of guns they are: electric heat guns or gas heat guns.
As already mentioned, the choice of a heat gun also depends on the conditions of its operation. First of all, here the emphasis is on diesel and gas heat guns. These types of heat guns are divided according to the type of fuel combustion, as guns of direct and indirect heating. Direct heating guns, such as Master gas heat guns, use the principle of fuel combustion without the removal of combustion products. Such devices can be used outdoors or indoors with limited time for people to stay.
Indirect heating prevents combustion products from entering the room and is suitable for use in rooms with a long stay of people.
When choosing a heat gun, you can be guided by the need to transfer it or install it permanently.
All heat guns are divided into portable and stationary.
Portable guns are needed for temporary space heating, for example, for construction sites, garages, workshops and other premises. The power of portable heat guns is not high and lies in the range of 2-30 kW.
Portable guns are manufactured with rugged housings that are resistant to weather conditions, damage and corrosion. Special models available for very damp environments and fire hazard areas. Stationary heat guns have a high heat output and can be used as the cheapest way to heat a room. Automatic systems will help you set the desired temperature for different time periods. Proper installation of heat guns also involves the arrangement of additional devices and structures. For example, for high ceilings, a ceiling fan that disperses warm air from top to bottom is suitable, and in closed rooms, install a chimney or provide good ventilation.
