Electric heat gun with own hands. Gas heat gun with own hands

In winter, an electric heat gun, made by hand, will serve as a reliable and effective means for maintaining the necessary temperature in almost any room, be it a large office or a confectionery shop. It is mobile enough, has a good percentage of efficiency and low power consumption and power. You can accurately calculate how much energy is required to heat a particular room.

All the charm is that the heat gun, made by your own hands, can be used in various places where there is no heating system. It will be a wonderful option for heating the building, where construction or repair work is going on, in large offices (more than 300 sq. M.), In assembly shops, etc. Many users do not suspect that a heat gun can be assembled at home. To do this, you need inexpensive materials, certain skills, desire and free time.

How does an electric heat gun work?

The heat gun (depending on the design features) can work on such fuels as gas (propane, butane), electricity or hot water. Before you begin to build a heat gun with your own hands, you need to study and understand the mechanism of its operation. A functioning heat gun (with their own hands it is made or at the plant, not so important) on this principle:

  • The heating element (TEN, gas pipe) collects the user-set temperature.
  • A built-in fan of sufficient power drives the chilled air through the chassis.
  • The heating element gives the necessary temperature to the air, which is pushed out by a hot stream into the room.

As a rule, a heat gun, made with all its requirements, has sufficient reliability and safety. It is capable in a short period of time to heat the air in the room to the required temperature.

Kinds

To understand what kind of heating device you need, and decide on the choice, we suggest you familiarize yourself with the main types of devices under consideration:

  • Electric heat gun. With your own hands, the device is made from a certain power source. As a rule, the device has power from 3 to 35 kW. A great option for use at home or in the garage. It is environmentally friendly and does not emit any combustion products harmful to humans.
  • Gas heat gun. With your hands, you can make a device that will have a power of 15 to 150 kW. It is connected to the gas system or cylinders. Among the shortcomings can be noted a large amount of energy consumed and the release of combustion products, though not dangerous for people.
  • Diesel heat gun. With its own hands it is more difficult to make than gas. This unit operates on liquid fuel (diesel fuel, kerosene). Has a power from 10 to 140 kW. Used only in ventilated areas.

Features of device assembly

First, we need to make a plan for how the electric or gas heat gun will be assembled by our own hands. It should take into account the basic characteristics of the device (for example, mobility, ergonomics, in other words, small size and weight). On the other hand, if you are going to make an electric gun at home, then such conditions are not necessary. You can choose your parameters, the main thing is that they do not differ much from the basic standards.

It is important to know

An obligatory condition for the use of a heat gun is the availability of a well-functioning ventilation system in the room.

This is due to the fact that the electric heat gun will heat the heater or spiral, which not only heats the air in the room, but also dries it.

The main stages of work

When choosing materials for the collection of an electric gun, one should take into account their technical skills, experience and financial capabilities. As practice shows, many masters collect an electric gun from what is at hand. There are options for how to assemble a device that is close to factory standards. Consider these:

  • So how is an electric heat gun made by yourself? Let's start with the home version, which involves assembling the device from everything useful that is in the garage or pantry. First of all, we need to find a pipe with a diameter of 300 mm and a thickness of 3-4 mm. If this is not possible, then a galvanized sheet of the same thickness is suitable. To work with steel, you need a welding machine. The pipe will become the body of the product.
  • The next important element of the future self-made heat gun is an electric motor with an impeller. To get it, we need a Soviet vacuum cleaner. It must be dismantled and the necessary element extracted. Do not advise disassembling new vacuum cleaners, as the schemes in modern models are quite complicated.
  • The extracted electric motor is installed on one of the ends of the already prepared pipe. At the other end of the housing is a structure that will heat the air blown out by the device. For this we need a nichrome spiral with a power of 2 kW and an asbestos sheet. These components can be purchased in any market or in a construction shop.
  • Asbestos sheet is cut into strips and we make a lattice of them. Install it on the opposite side of the electric motor. On the finished grid, fix the future TEN - nichrome spiral. To create a power circuit, you do not need to install separate units or solder circuits. It's pretty simple.
  • Now we need a switch to close the circuit, a wire with a plug and fuses. To our heater we connect a fuse of 30 amperes, for the engine it will be necessary for 7 amperes. If there is such a vacuum cleaner, then you can use it. All the elements are fixed, according to the plan, by a specially prepared instrument.

The above-described variant of assembling an electric heat gun will make it possible to produce a device of low power, but it will suffice to heat an apartment or office with an area of 50-60 square meters. M. With competent assembly and reliable materials, the output will be an excellent device for heating.

Assembling a more powerful heat gun

If the above option is not suitable for heating the room, then you can make a heat gun with your own hands more powerful. True, the materials will have to be bought or ordered.

As for the build principle, it does not change much. You need to increase the walls of the case yourself, pick up a powerful electric motor, put more efficient fuses. For a high-power thermal gun, a simple electric motor without an impeller is perfect. It is adjusted to the required number of revolutions. Also a combined fan will be needed, but it will be more difficult to find it on the market.

Helpful Tips

Before we look for assembly schemes and buy the necessary elements for a future heat gun, we advise you to really assess your own capabilities, experience and knowledge in this matter. Basically, all the schemes and videos devoted to the assembly of such a device are fairly simple, but the risk of making a mistake is great enough.

This is very important to understand, since an admitted miss can cause not only a failure in the power supply system, but also a fire.

Conclusion

If you have a huge desire to build an electric heat gun with your own hands, and for this there are all the necessary materials and conditions, why not satisfy your interest? We recommend that you first consult with people who already have experience in assembling such heating devices.

The repair of a heat gun with its own hands is quite simple and does not require special knowledge. This is also a plus. To make a more complete presentation, you can refer to the videos, which explain in detail and show how the electric heat gun is assembled with their own hands. Always remember your own safety.

So, we have in general found out how the electric and gas heat gun is made by our own hands.
