The widest range of heating equipment present on the modern market allows you to choose the most efficient device for yourself, which is fully suitable for specific operating conditions. We will not dwell on all these devices, but we will only talk about electric heat guns. What are they and what design do they have? Is it possible to make such a heat gun at home? You will learn about this, as well as many other things, after reading this article.
electric heat guns
We should start with what exactly is meant today by heat guns. First of all, they are heating devices representing a group of thermal fans. At the same time, they differ from the same fans in high heat output and power. Therefore, here all units with a power of more than 2 kilowatts belong to electric heat guns.
TOP 3. Rating of the most popular manufacturers
No. 1. Heat gun Ballu electric
The world's largest company engaged in the manufacture of climate technology. If we consider the range of this manufacturer, then special attention should be paid to the Foreman model, which has several modifications at once.
Design features include:
- double case, which is made of "stainless steel";
- power, which ranges from 1.5-9 kilowatts;
- the ability to adjust the angle of inclination of the device.
Note! The foreman cannon will cost from 2,700 to 6,000 rubles. A more specific figure depends on what kind of power we are talking about.
No. 2. "Tropic"
A worthy representative of Russian manufacturers of climate control equipment is the Tropic enterprise, which specializes in the manufacture of budget options for heat guns. One of the best devices of this manufacturer are the models of the TK line.
Of course, the main advantage of all Tropika products is their cost. At the same time, the company properly monitors the quality of the goods, as well as ensuring that its technical characteristics fully comply with international standards.
No. 3. Frico
This Scandinavian manufacturer offers high-quality electric heat guns, but in Russia its products are known mainly for small-sized fan heaters from the Tiger series. But in order to effectively and quickly heat rooms with a large area, it is advisable to give preference to the company's new product - the stationary heat gun SWH02 Fan Heater.
This model is distinguished, first of all, by ease of installation and operation, as well as automatic adaptation to the microclimate of the room in accordance with the established operating mode.
Note! The approximate cost of the SWH02 Fan Heater unit is from 43,000 rubles.
The design and principle of the electric heat gun
So, what is the device described in the article? In order to find out, you must understand one important point: a heat gun is an unusual device that can heat almost any room in a short period of time. In other words, this is a device designed for rapid heating and effective drying during various technological operations.
You will probably ask another question - why is this device even called a heat gun? The thing is that outwardly this unique heating unit is very similar to the design of a traditional army gun, but at the same time it can heat rooms with high quality.
For the most part, heat guns include the following structural elements:
- actually, the heating element;
- air filter (present on some models);
- high power fan;
- thermostat (it is necessary so that the device can function offline, that is, the temperature regime in the room is pre-set, from which the gun works);
- metal case, characterized by increased strength indicators;
- thermostat (necessary in order to prevent overheating of the device).
What is the very principle of action? And it consists in a series of actions that are performed in a certain sequence.
- Stage one. The heating element produces heat energy.
- Stage two. Through a special hole located on the case, cold air enters the device.
- Stage three. The air is warming up. A powerful fan pumps hot air, moving it to the desired location in the room.
What are heat guns?
You need to know this in order to understand the differences between electric models from others. The classification in this case is based on the method of converting various types of energy carriers into thermal energy. Simply put, all heat guns are classified depending on what kind of energy carrier is used in order to receive heated air.
Note! Speaking specifically about electric heat guns, they, in turn, are also divided into several types, so we will briefly consider them.
Types and characteristics of electrical appliances
According to the features of their operation, electric heat guns are divided into two categories.
Advantages of using electric heaters
The advantages of the equipment described in the article include:
- light weight;
- affordable cost (a 220 volt device is the cheapest of all presented above);
- ease of use (the device is activated by pressing just one button).
Minuses
However, there are drawbacks - for example, the described heat guns:
- directly dependent on the electrical network (it is worth noting that, if possible, devices can be connected to diesel generators);
- consume electricity, which is expensive.
Criteria for choosing electric heat guns
People choose electric heat guns for certain purposes, therefore, without fail, pay attention to the criteria below.
Equipment power calculation
The easiest way to calculate the power of a heat gun is as follows: to heat 10 square meters of a room, you need power from 1 to 1.3 kilowatts. For example, if the area of the room to be heated is 80 square meters, then a gun of approximately 80-100 kilowatts should be selected for it.
Note! Also, a special table, which we have given below, should help you in the calculations.

Is it possible to make a thermal electric gun with your own hands?
To create such home-made units, various elements and devices sold in all hardware stores in the country can be used. So, for the body you can use a pipe (it is important that the material is not a conductor of electric current), for example, asbestos. Or, as an option, you can even build a plywood box. Move on. A nichrome spiral can serve as a heating element (this is used in irons and other household appliances). To increase the heating capacity of the spiral, it is quite possible to fold it in half.
Important information! This spiral must be connected to a thermostat - it will regulate the degree of heat.
In this case, the spiral should be located inside the box or pipe (approximately in the center of the structure), and the thermostat itself should be outside. A fan heater should be located at the end of the case, it can be of not very high power. In principle, this is how a low-power electric heat gun is arranged.
Note! The spiral and the fan must be connected to the AC mains, and must be connected separately.
Step by step instructions for making
As an example, let's take a look at one of the simplest structures. To get started, you need to prepare:
- duct type fan;
- regulator (it must adjust the rotation of the fan rotor);
- heating element (we recommend using RVEC, the power of which is 2.2 kilowatts);
- thermostat;
- plywood (its thickness should be 1.6 centimeters);
- various fasteners.
So, when everything you need is already at your fingertips, you can proceed directly to manufacturing. The procedure itself consists of several stages, consider the features of each of them in more detail.
Step one. First prepare the base of the unit. It is on this basis that all structural elements will be located. For this purpose, take a sheet of plywood, then cut a rectangle out of it with dimensions of 67x47 centimeters. At the end, carefully process the cut piece with sandpaper.
Step two. Due to the fact that the heating element you are using, as well as the duct-type fan, is already a ready-made device in itself, simply connect them to each other using a mounting clamp. Install the resulting dual device on a previously prepared plywood stand. Use a plastic clamp designed for sewer pipes and a bracket for this. Attach the latter to the plywood sheet with the help of self-tapping screws, and already to it, respectively, by means of self-tapping screws, attach the outlet pipe of the heating element itself.
Note! The back of the fan will rest on the stand.
Step three. Having installed and attached all the elements of the heat gun, you can begin assembling the electrical part of the unit. Take a heater with a fan and connect them (but, as mentioned earlier, only separately from each other). Therefore, for this reason, it is necessary to connect a thermostat to the PBEC. In addition, you can also install a temperature sensor necessary for temperature control.
Step four. Connect a rotation regulator to the fan, due to which the intensity of air movement on the heating element will change, which, in turn, will help regulate the heat in the room.
Step five. To move the heater as conveniently as possible, you can fix four wheels at the bottom of the plywood sheet. Everything, the manufacturing process can be considered complete!
So, now you know everything about electric heat guns, got acquainted with the technical characteristics, prices and popular models. That's all, good luck and warm winters!
