Electric heat guns: reviews and schematic diagram

Electric heat gun is a device that heats by using a powerful tubular electric heater in the form of a TEN. The fan is one of the important parts of the design. From the unit, hot air is not blown out, but it is processed in a heat exchanger, due to which the temperature inside the room is rapidly increasing. The device is powered by an electric generator or mains. From corrosion the metal casing protects the layer of polymer coating of the highest quality.

If you are interested in an electric heat gun, how to choose the most suitable device for your home, our article will tell.

general description

Electric heat guns, whose reviews indicate extreme efficiency and ease of use in various conditions, usually have a rectangular shape, with the shape of the heating element they have M-shaped. Devices in a cylindrical body are equipped with a heater having the form of a spiral. Such devices allow to obtain a higher temperature at the output in comparison with rectangular models.

The heating power can be regulated in a stepwise manner. With the help of the built-in thermostat it is possible to maintain a certain temperature of the heated air at the proper level. Due to the use of built-in thermal protection, the device is not subject to overheating. The operation of the electric gun can occur in the fan mode. There is no strong heating. Electric heat guns, reviews of which indicate the thoughtfulness of their design, differ from gasoline and diesel in that they provide absolute safety in operation. The location of the heating element is well provided, it is placed behind a strong mesh, which completely eliminates the contact of people with it.

Features of use

Electric heat guns, reviews of which are mostly positive, will be appropriate for use in any apartment. Such a device is absolutely irreplaceable during the repair, as it is able to dry out the painted surfaces as efficiently as possible. This device will allow you to organize dinner on the open veranda even on a very cool evening, while the surrounding conditions will be quite comfortable. But still it is worth considering that such fan heaters are designed primarily for use in a closed cycle of air exchange, so the heating efficiency is significantly reduced if you use a heat gun in an open space.

The choice of the device depending on the size of the room

Industrial thermal electric guns are used in large areas, for example, in huge office or warehouse buildings. At the moment, a wide range of domestic and foreign products is on sale, while prices are quite acceptable, for example, for the products of the company "Resanta".

A thermal electric gun must be purchased with a preliminary estimate of the area and height of the room, as well as its thermal insulation properties. The device of a small power of not more than 1.5 kilowatts is able to cope with the heating of the room with an area of 15 square meters, with a wall thickness of 15 centimeters and more, and also with the condition of high-quality thermal insulation.

If it is a question of concrete walls and windows that are not a good barrier to cold air, then there are required electric heat guns, the reviews of which speak for themselves. In this case, you can choose either one device of higher power, or a few weaker ones, which will ensure an even warm-up. If the device is intended to be used in an open space, its capacity should be much higher than the area of the room to be heated. This is due to the fact that in a street environment, warm air flows are expended many times faster than in a confined space.

Device construction

The scheme of the electric heat gun assumes the presence of quite certain components, but there are also optional components. For example, in the unit there is not always a relay for temperature control. Most often the process of regulation is due to the exclusive switch operating modes. This leads to a change in the intensity of the air currents that pass through the heating elements.

If you decide that you just need a heat gun electric, some expert advice will help to make the right choice. First of all, you should take into account the permissible load on the electrical wiring. Any device of this category is inclined to consume a large amount of electricity. And not every network will support such a device. The connection of some heat guns is carried out to a network of 380 volts. These devices are classified as professional, as they can not be used in domestic premises. In apartments and private homes can be used thermal electric guns, which connect to a normal outlet with a value of 220 volts. Equipment with a capacity of 3-15 kilowatts can be used for the permanent heating of garages, warehouses, dryers, and industrial premises. It is important to remember that it is almost impossible to heat a wooden shed, a large hangar or an iron garage. Thermal electric guns (220 V) in such cases will not work.

Installation

The electric heat gun can be mounted on walls, and the installation angle can be arbitrary. This makes it possible to select the optimum air flow in each individual case. The device can be installed directly on the floor, choosing the most convenient place for this.

There are electric heat guns, the reviews of which speak of their extreme legal capacity, suitable for functioning in rooms classified as fire-dangerous due to increased dustiness. In addition, devices that can function in a corrosive environment have already been developed. With their help, heating facilities such as sewage treatment plants and car wash facilities are carried out.

An increased class of protection against moisture is an important characteristic that a thermal electric gun possesses. How to choose such a device? All the necessary information can be obtained from the device's passport and its technical characteristics.

Principle of operation

Electric heat guns operate on the principle of convective heat transfer. By means of a fan, cold air advances to the heating element, and then is fed into the rooms, while its temperature is already noticeably higher. Many modern models have a built-in thermostat that automatically switches off the heating in automatic mode if the necessary temperature values have already been reached, and then turns it on when the air in the room cools. Usually such a thermostat is placed at a certain distance from the device itself, so it shows the actual actual temperature inside the room.

Type of heating element

By the type of heating element, which is used inside the gun, all instruments of this category can be conditionally divided into ten and spiral. A cheaper, however not very reliable option is a nichrome spiral, so devices based on it have a power of up to 10 kilowatts. Devices with a higher power are equipped with electric heaters, so that the efficiency of the device increases significantly together with safety. For example, the electric heat gun "Ballu" is characterized by the presence of heating elements of improved design, which significantly increases their working life.

Appearance

It takes into account such nuances as aesthetic appeal, achieved through the use of two basic forms - rectangular and cylindrical, as well as high-quality paint and dimensions of the unit. If the device is planned to be used exclusively for domestic purposes in a small room, then a compact heater with a mass of 5-10 kilograms with dimensions within 25-50 centimeters is the best option. If there is a need to purchase a larger unit, it is worthwhile to be ready to transport equipment, the weight of which is 50-150 kilograms at a size of 1-3 meters for each of the parameters.

conclusions

If you have thought out and calculated everything well, you have decided on the list of basic requirements and characteristics that the device should possess, then you just have to decide and purchase the model that best suits your needs. The above recommendations will allow you to choose the thermal electric gun that can work for a long time, satisfying all your needs. This device is good in that, with its compactness, convenience and functionality, it is able to warm up the room quickly and qualitatively. The external data of thermal cannons do not stand in the last place when choosing, so it is worthwhile to focus on them.
