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.

Heat guns cat­a­log

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.
