An electric heat gun is a device that heats up through the use of a powerful tubular electric heater in the form of a heating element. The fan is one of the important parts of the design. Hot air is not blown out of the unit, but it is processed in a heat exchanger, due to which the temperature inside the room is rapidly growing. The device operates from an electric generator or an electrical outlet. A metal casing protects the highest quality polymer coating layer from corrosion.
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, reviews of which indicate extreme efficiency and ease of use in various conditions, usually have a rectangular shape, while the shape of the heating element is M-shaped. Devices in a cylindrical case are equipped with a spiral-shaped heater. Such devices make it possible to obtain a higher outlet temperature in comparison with rectangular models.
The heating power can be adjusted stepwise. Using the built-in temperature controller, 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 exposed to overheating. The operation of the electric gun can occur in fan mode. In this case, there is no strong heating. Electric heat guns, reviews of which indicate the wisdom of their design, differ from gasoline and diesel in that they provide absolute safety during operation. The location of the heating element is well provided for, it is placed behind a strong mesh, which completely eliminates contact with people.
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 indispensable during the repair, as it is able to dry painted surfaces as efficiently as possible. This device allows you to organize dinner on the open veranda even on a very cool evening, while the conditions surrounding you will be quite comfortable. But still it is worth considering that such heat-ventilating equipment is primarily designed 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 device depending on the size of the room
Industrial electric heat guns are used in large areas, for example, in huge office or warehouse buildings. At the moment, a wide range of products of domestic and foreign production is on sale, while the prices are quite reasonable, for example, for the products of the Resanta company.
A heat electric gun should be purchased with a preliminary assessment of the area and height of the room, as well as its heat-insulating properties. A small-capacity device of no more than 1.5 kilowatts is able to efficiently cope with heating a room with an area of 15 square meters, with a wall thickness of 15 centimeters or more, and also subject to high-quality thermal insulation.
If we are talking about concrete walls and windows, which are not a good barrier to cold air, then electric heat guns are required, the reviews of which speak for themselves. In this case, you can choose either one device of greater power, or several weaker ones, which will ensure uniform heating. If the device is supposed to be used in an open space, then its power should be much higher than the area of the room that is supposed to be heated. This is due to the fact that in street conditions, warm air flows are expended several times faster than in confined spaces.
Device device
The scheme of the electric heat gun assumes the presence of well-defined components, but there are also optional components. For example, a relay for temperature control is not always present in the unit. Most often, the regulation process occurs due to the exclusively switch operating modes. This leads to a change in the intensity of air flows that pass through the heating elements.
If you decide that you just need an electric heat gun, some expert advice will help you make the right choice. First of all, the permissible load on the electrical wiring should be taken into account. Any device in this category is prone to consuming large amounts of electricity. And not every network will support such a device. Some heat guns are connected to the 380 volt network . These devices are classified as professional because they cannot be used in domestic premises. In apartments and private houses, thermal electric guns can be used, which are connected to a conventional outlet with a voltage of 220 volts. Equipment with a capacity of 3-15 kilowatts can be used for continuous heating of garages, warehouses, dryers, as well as industrial premises. It is important to remember that it is almost impossible to heat a wooden barn, a large hangar or an iron garage. Thermal electric guns (220 V) in such cases will not work.
Installation
An electric heat gun can be mounted on walls, while the installation angle can be arbitrary. This allows in each case to choose the optimal air flow. The device can be installed directly on the floor, choosing the most convenient place for this.
There are electric heat guns, reviews of which speak of their extreme capacity, suitable for operation in rooms classified as fire hazard due to increased dust content. In addition, instruments capable of functioning in a corrosive environment have already been developed. With their help, heating facilities such as wastewater treatment plants and facilities for washing vehicles.
The increased class of protection against moisture is an important characteristic that an electric heat gun possesses. How to choose such a device? All necessary information can be obtained from the passport of the device and its technical characteristics.
Principle of operation
Electric heat guns work on the principle of convective heat transfer. By means of a fan, cold air moves to the heating element, and then is supplied to the premises, while its temperature is already noticeably higher. Many modern models have a built-in thermostat, which automatically turns off heating if the necessary temperature indicators are already reached, and then turns it on when the air in the room cools down. Typically, such a thermostat is placed at a certain distance from the device itself, so it shows the really real temperature inside the room.
Type of heating element
By the type of heating element that is used inside the gun, all devices of this category can be conditionally divided into heating elements and spiral. A cheaper, but not very reliable option is a nichrome spiral, so devices based on it have a capacity of up to 10 kilowatts. Devices with greater power are equipped with heating elements, so the efficiency of the device increases markedly with safety. For example, the Ballu electric heat gun is characterized by the presence of heating elements of an improved design, which significantly increases their working life.
Appearance
This takes into account such nuances as aesthetic appeal, achieved through the use of two main 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, the mass of which is 5-10 kilograms with dimensions in the range of 25-50 centimeters, is the best option. If there is a need to purchase a unit of greater capacity, then you should be ready to transport equipment, the weight of which will be 50-150 kilograms with a size of 1-3 meters for each of the parameters.
conclusions
If you thought it over and calculated it well, decided on a list of the basic requirements and characteristics that the device should have, then you just have to decide and purchase the model that best suits your needs. The above recommendations will allow you to opt for a heat electric gun that can work for a sufficiently long time, satisfying all your needs. This device is good because with its compactness, convenience and functionality, it is able to quickly and efficiently warm the room. External data of heat guns is not in last place when choosing, so you should focus on them.
