With the onset of cold weather, appliances powered by electricity are most often used to heat the room. The modern market offers a huge selection of fan heaters, oil radiators, convectors, etc. Nowadays, electric heat guns are rapidly gaining popularity, allowing you to warm up the air in any room in a matter of minutes.
Design features of a heat electric gun
Depending on the model, electric heat guns can operate on 220 or 380 volt AC power. Powerful electrical appliances are used in production. For domestic needs, models operating on a 220 volt network are used.
To get to know the electric heat gun better, let's look at its structure:
- All elements of the thermal electrical appliance are located in a metal casing. The gun is equipped with a comfortable handle for moving. A metal stand is fixed underneath the body.
- An electric heating element is installed inside the housing, acting as a heater. It produces heat after applying 220 or 380 volts to it. The manufacturer uses tubular models. Such heating elements last longer and are fireproof.
- There is a reflector around the heater. It prevents the body from overheating and directs heat into the outlet of the electric gun - the nozzle.
- A fan is located in front of the heater, that is, on the back side of the heat gun. It is driven by an electric motor running on 220 volts.
- Any model of electric heat gun is equipped with overheating protection. The sensor turns off the voltage supply to the heating element when the temperature of the device body approaches a critical level. The automatic operation of the heat gun is controlled by a thermostat. It allows you to maintain the set temperature.
- Control keys are installed on the body of the electric gun. Usually they have a light indication.
Electric heat guns operate on the principle of the familiar fan heater. That is, they take in cold air and give out warm air. A fan installed in front of the heating element creates an air flow while rotating its blades. Passing through the heating element of the electric gun, the air takes away heat, after which it enters a directed point in the room through the nozzle.
The main advantage of an electric gun over analogues running on gas and diesel fuel is its environmental friendliness. During operation, the electrical appliance practically does not burn oxygen, and there are no emissions of harmful substances along with combustion products.Owners of diesel heaters know how difficult it is to start them in the cold to warm up a garage or warehouse. The electric gun will turn on without problems at any negative temperature, as long as the voltage is 220 or 380 volts. But if there is no connection to the electrical network nearby, you will not be able to use the heating device, and this is its only disadvantage.
Scope of application of electric heat guns
Due to their good technical characteristics, electric guns are widely used in many areas of human activity:
- With the onset of cold weather, a heat gun is the best source of heat for an apartment until the central heating works. You can take the device with you to your dacha, install it in a glassed-in gazebo, use it to heat your office, etc. In general, an electric heat gun can be used in any room where people are.
- For economic purposes, using an electric heater helps dry out a cellar or pantry, warm up a car in severe frost, and maintain an optimal temperature in a greenhouse.
- An electric gun is indispensable when performing construction and repair work. The device is used to heat the canvas when installing a stretch ceiling, drying plaster, etc.
- In industry, powerful three-phase thermal units are most often used to heat large workshops, and they are also used to perform certain technological work.
An electric heat gun can work under almost any conditions, the main thing is to use it carefully inside damp rooms. It is also important to pay attention to the electrical wiring.If the cable cross-section is weak, it will overheat and subsequently burn out.

Rules for choosing an electric heat gun
According to many people, a good heater is one that consumes little electricity and provides excellent heat. In some ways they are right. But how to choose the best heat guns among a large number of models? It should be noted right away that all electric heat guns operating from a 220 V network consume little energy. And this is not connected with the power of the heating element. The fact is that the heater turns on for a short time. When the maximum threshold of the set temperature is reached, the heating element turns off, and only the fan, which consumes little electricity, remains running.
However, the consumer must clearly understand what criteria should be used to select an electrical appliance:
- First, a person needs to decide why he is buying an electric heat gun, that is, what tasks the device will cope with. If this is periodic heating of a small room, then it is reasonable to give preference to a low-power gun. For repair work or heating a greenhouse, it is worth buying more professional models.
- The second important factor is the features of the room where the heat gun will operate. The area, configuration, and quality of thermal insulation of building elements are taken into account. These parameters are used to determine what power and how many electric guns you need to buy.
- When choosing an electrical appliance based on power, you must first test the network. First, they determine what voltage is supplied: 220 or 380 volts. Secondly, you need to make sure that the cross-section of the wires is sufficient for such a load.
- Parameters such as the weight and size of a heat gun are not very important, but the comfort of working with an electrical appliance depends on them.
- Regarding the price, it should be noted: not everything good is expensive. Sellers often increase the price of a product because of the brand name. When choosing an electric heat gun, they are guided by the technical characteristics of the device, and then decide on the manufacturer and price.
Almost all models of heat guns are designed to operate for up to 10 years under the conditions recommended by the manufacturer. That is why you should carefully approach the choice of electrical appliance.

IR heat guns
In terms of popularity, infrared heat guns operating on the principle of radiation compete with electric models. IR devices do not have a built-in fan, since there is no need to create an air flow. Infrared rays heat the surface of any object, and it, in turn, gives off heat to the air.
However, it must be taken into account that only those objects that are in the radiation region receive heat. This determines the specifics of using IR heat guns. The device is relevant where spot heating is required.
What is better to buy: an electric gun or a fan heater
The operation of an electric gun and a fan heater is almost the same. Both electrical appliances use a fan to force air flow through the heating element. An inexperienced person takes what is cheaper - a fan heater. However, you need to know that these devices, which are similar in functionality, have significant differences.
So, any of these devices are purchased to heat a specific object.Here you need to take into account the volume of heated air. The power of fan heaters is limited to 1–2 kW, and the electric gun is capable of delivering more than 4 kW per hour. This is where you should think that to heat a large hangar it is better to buy one heat gun than ten fan heaters.
But in an apartment it is better to give preference to a fan heater. They are more compact, more beautiful, and the power of 1–2 kW is enough to heat one room. Expensive models of fan heaters are equipped with ceramic heaters that do not burn oxygen during operation. Cheap devices have regular spirals inside. It is not advisable to use them in a residential area, especially if the humidity is very high.
Almost all fan heaters have a function to turn off the heating element. In an apartment, such a device can be used in the summer instead of a fan to cool the air. Now manufacturers have begun to provide electric heat guns with this function. The devices can even have three-stage adjustment of the supply air temperature: cold, warm, hot.
