How to choose an electric heat gun 220V specifications

Heat gun installed on any horizontal surface. If necessary, the construction can be moved. The device runs almost silently, that does not affect adversely on the tenants of the apartment or the working environment in the office. From the technical characteristics of the gun depends on its performance. To decide which is better heat gun, you should examine its options.

Note!When you first turn on the new gun may cause a slight odor. It is considered normal. In the course of further operation of it we will disappear.

Picking up the heater, you need to pay attention to the following characteristics:

• power level;
• presence or absence of the possibility to configure the power degrees;
• Fan performance;
• the rate at which preheated air stream exits the structure;
• outlet air temperature;
• voltage in the electrical network;
• number of operating modes;
• the level of fire safety;
• dimensions of the device;
• degree of mobility;
• decorative qualities;
• noise exposure;
• additional functionality.

How to choose an electric heat gun: the calculation of the optimum power

To decide which to buy a heat gun for a garage, you should figure out how to design power indicator should possess. This takes into account the size of the room. For example, if the garage dimensions are 4x6 m, by simple calculations can find the desired record.

To start with the room area is calculated. In this case it is 24 m². Experts recommend to the desired power rating to add a small margin in the form of 20% of this value. The result: 2,4h1,2 = 2.88 kW. So, for a specified minimum power premises heat gun - 3 kW.

There is another technique. It allows you to get a more accurate result. This embodiment is desirable to use for calculating the thermal power electric gun for a house. In this case the formula is based not on the floor area, and the degree of thermal conductivity of the walls and the volume of the room.

First you need to get the performance needed for the calculations:

1. Room volume (m³) - calculated area of ​​the room, and then multiplied by the height of the ceiling.
2. The difference in temperature between the outside and inside.
3. Coefficient of thermal conductivity of the walls.

Table thermal conductivity materials:

wall material	the thermal conductivity coefficient
Surfaces with high-quality thermal insulation	06,-1
Brick-row masonry or wall having an average level of thermal insulation	1-2
Surfaces with poor insulation	2-3
The walls of the planks or profiled sheet (Commercial)	3-4

To understand how to choose a heat gun is enough to perform the necessary calculations, considered as an example of the same garage. The volume of the room: 4h6h3 = 72 m³. If the temperature outside the building is -20 ° C, and in - 15 ° C, then the difference will be 35 °. Taking the insulation factor of 1, we obtain: 35h72h1 = 2520 Kcal / h. The 1 kW contains 860 kcal.

The result should be divided by 860 calories and you end up with 2.93 kW. If we consider that the power of the gun taken with a reserve, then this room will need a device that has a 3.5 kW.

Useful advice!You should not buy a gun with a high capacity to house. Such devices banish strong flow of air, so it will create a lot of noise during operation.

How to choose a heat gun: the voltage and duration of the

Operating voltage - another characteristic that needs attention. On the market there are machines whose power exceeds 20 kW. For operation of such structures requires three-phase electrical network where a voltage of 380V. If you plan to buy just such a heat gun to heat, be sure to take care of the wiring is replaced by a more powerful version.

Constructions, which does not exceed the power of 7 kW, may be powered by mains voltage of 220V under the condition that the section of wires is designed for such loads. Before connecting a heat gun, it is desirable to calculate the optimal section cables with the power and current. This avoids problems with the wiring and circuit.

When choosing a heater is also necessary to pay attention to uptime. The device is unable to work for a long time without shutting down, otherwise it will quickly fail. For this reason, manufacturers of heat guns applied to the housing marked "24/1" or "24/2". This means that the device can operate around the clock with a break for 1-2 hours depending on said notes.

There are other specifications that affect the operation. When choosing a device, be sure to pay attention to the level of noise exposure and the temperature range in which the gun can effectively carry out their work.

Note! Minimum operating temperature range for good device is 5-40 ° C.

How to make your own hands an electric heat gun

Electrical apparatus for space heating can be done independently. The simplest design consists of a heating element, a fan and an electric motor. All this is hidden in a metal enclosure. The most difficult step is the development of the electrical circuit. To avoid errors, you can use ready-made options, which can be found on the Internet. In most thermostats in the circuit and the dial are connected in series. Short circuit occurs in the electric motor and the heating element.

assembly technology is a simple design with TAN

As for future gun housing can take a scrap of large diameter pipe. To this end, suitable metal or asbestos cement. Case size must be chosen taking into account the magnitude of the fan blades, which must cover one of the end sides of the device. Ready TEN can be bought at the store or take it from an old boiler or stove. To work need to switch opens the circuit with three wires cable, safety machine screws.

Useful advice! can be used and available means, such as a metal tank of small size for body, old pan galvanized bucket. The main thing is that the design had thick walls.

To start device defined by the required power. For this formula can be used, which has been viewed earlier. Then you need to check whether the wiring in the room stand such a load.

Further, the body portion is made. If the hand is not a metal tube can take steel sheet. It is folded into position and secured by means of rivets, welding or hoops. If you intend to use buckets or pans should saw off the bottom. The result should be a housing of rectangular or cylindrical shape.

Then, the resistance heating element is compared with the calculated data. If in fact there is a need, in the chain, you can add 1-2 additional elements, which are connected in series. To increase the power, heater is shortened. On one end is fixed an electric motor and a fan. The blades should be possible to block the lumen, but nothing should prevent rotational movement. Connect network wires via the fuse. It also set the switch.

TEN must be secured within the housing, preferably in the center. The fasteners can be used as a plate made of refractory metals, or rivets. The heating element should be placed at a sufficient distance from the fan, otherwise the engine will be exposed to excessive heat. Wires to be output and connect to the network through a different fuse.

The design is completely ready. Before you begin to operate it, you must check the quality of the insulation on all connections and perform a pilot test. If the assembly is correct, starts from one end of the fan, and the second will be leaving the heated air. This gun is very easy to manufacture and requires only a minimum of time and knowledge in electrical engineering, although much safer to buy a ready instrument in the store.
