Choosing an electric heat gun for home and garage

Specifications

first on what you need to make a start - which parameters are suitable for the normal operation of the electrical heatgun.The selection must be carried out by a suitable power and voltage.

With regard to the first characteristic, there are two options calculation.A simpler method of determination is that the heating 10 sq.m.premises must be at least 1 kW of power.Total, if you have the room 4 * 6 meters (eg garage), simple calculations show that it is necessary to select the power of electric heat gun, no less than 3 kW.We have identified as follows: 4 * 6 to 24 meters, taking into account the recommendations that the power supply should be at least 20% have 2.4 * 1.2 = 2.88 kW.The closest is 3 kW, which also need to pick up for heating the garage.

second method of calculation is more accurate, and we recommend its use when choosing an electric heat gun for home.In this case, the formula takes into account not the floor area, and its size and the coefficient of thermal conductivity of the walls.As a result, the formula is:

P = (V * dT * Kt) / 860 ,

where:

• V - room volume is calculated as the area multiplied by the height of the ceiling, m3;
• dT- difference ambient and indoors;
• Kt - coefficient of thermal conductivity.For walls with high-quality thermal insulation of 0.6 to 1. The average insulation or brick masonry in two rows - from 1 to 2. Single-row bricklaying, poor insulation - from 2 to 3. Dilapidated sheds made of profiled sheet or board - accepted ratio of 3 to4 $
• 860 - the number of calories per 1 kW.

power Marking - 9 kW

you to understand the nature of the calculation, again, look at it as an example.You have decided to choose an electric heat gun for a garage - or rather, warming machine.The volume of the room - all the same 4 * 6 * 3 meters (ceiling height).The temperature inside the buildings must be + 15 ° C, -20 ° C is now behind.Total, the difference is 35 degrees.Garage is insulated well, so accept rate 1. As a result, calculation formula would be: 72 * 35 * 1 = 2520 kcal / h.To put a value in kWh, you must divide it by 860.The result - 2520/860 = 2.93 kW.In view of the stock necessary to carry out selection of the heat gun is not less than 3.5 kW, which is enough.

capacities Table

immediately draw your attention to the fact that there is a conventional classification by power devices.It is estimated that up to 5 kW is heaters, and already over - gun.Review of domestic heaters with reviews of the most popular models we examined in the relevant article!

second, equally important technical characteristic is the operating voltage.There are electric heaters, power over 20 kW, which is necessary to work, of course, the three-phase network of 380 V. This time, you should also take into account if you decide to opt for heating the garage or garden electric heat gun, replace the wiring in the house to a new, more powerful.Devices up to 7 kW can be connected to single-phase 220 V, if the wire cross-section allows.It is best to make a connection cable cross-section calculation power and current, to make sure that your wiring to cope with such current loadings.

Well, the last thing you need to look for when choosing a heat gun - the duration of the work.As you know, the gun for heating the room, it should work without a break for a long time.That is why the device manufacturers indicate the body to "24/1" or "24/2", which consequently means work around the clock with a break of 1-2 hours.

addition to choose the right electric heat gun characteristics, pay attention to the noise level of its work and the range of operating temperatures.Modern devices have to operate at temperatures less than from + 5 ° C to 40 ° C.

Type

next, equally important criterion for choosing an electric heat gun - depending on the type of room.For example, for the house you need to buy an indirect heating device, the design of which includes the exhaust system.This is due to the fact that in a private home there are people and animals on which the exhaust gases can affect adversely.Although in relation to the Electric heaters this time not urgent, you still need to know about the importance of indirect heating.If you want to choose a heat gun for a greenhouse warming of the machine, it is better not to overpay and buy a simpler version of the design.

Here we should note one more important thing - if you want to select an electric heat gun for temporary heating, buy a carrying case.If the heater has to work a long time in one place, for example, in the country - choose a fixed-type device that needs to be fixed in a certain place in the room.

Additional options

With those kind of electric heat gun is best to choose power and depending on the type of premises, we understand.But that's not all you need to know about this issue.It is very important when choosing a heater pay attention also to the following points:

1. technique should have a temperature controller, at least a step.The thermostat allows you to control efficiency and productivity of the electric heater.
2. Pay attention to be present automatic shutdown in case of overheating.If by chance the body will fall, and the heater starts to overheat, fire situation will not arise, becausework thermostat.
3. Metal case much better plastic and composite.First, the metal is stronger, and secondly, if the electricity is shut down abruptly, a red-hot heater will not harm the metal body heat gun.At the same time, the plastic may melt and cause a fire.
4. cylindrical device capable of several times to warm up the room quickly, becausea heating element which is in a spiral.This option is more suitable for the electric heating of the garage, if you need to quickly warm up the car in the morning.
5. Selecting electric heat guns rectangular shape is more rational for heating private house and garden, which is related to the type of heating element inside - the grid, which is not as dry air and less dangerous in terms of spontaneous combustion.
6. Before buying check if the selected manufacturer's service center in your city, becausein case of failure repair can be costly.Here it should be noted immediately that the company is better to choose an electric heat gun from vendors such as Ballu, Master, TEPLOMASH, Veab and Dantex.
7. Few people know, but tselnoshtampovannyh impeller creates the most powerful airflow.If you need a good electric heater on the scene, for example, for the installation of stretch ceiling, be sure to select a device with such a fan!
