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

In the winter time, the electric heat gun, itshands made, will serve as a reliable and effective means to maintain the necessary temperature in almost any room, whether it is a large office or a confectionery shop. It is sufficiently mobile, has a good efficiency percentage and low power consumption and power. You can accurately calculate how much energy is required to heat a particular room.

The whole beauty is that the heat gun, itshands made, can be used in various places where there is no heating system. It will be a wonderful option for heating a building where construction or repair work is going on, in large offices (over 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?

Thermal gun (depending on the constructionfeatures) 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 connection) 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, with their own handsmade with all the requirements, has sufficient reliability and security. It is capable in a short period of time to heat the air in the room to the required temperature.

Kinds

To understand which 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 manufactured device operates froma certain power source. As a rule, the device has a 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 thatwill have power from 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. It's harder to make it with your own hands 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

To begin with, you need to make a plan for howto collect an electric or gas heat gun with their 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 using 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 electricalguns 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?own hands? 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-madeheat gun - an electric motor with an impeller. To get it, we need a vacuum cleaner of the Soviet model. It must be disassembled and extracted the necessary element. We do not recommend disassembling new vacuum cleaners, as the circuits in modern models are rather complicated.
The extracted electric motor is installed on onefrom 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 made fromtheir grating. 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 for closingchains, a wire with a plug and fuses. To our heater we connect a fuse of 30 amperes, for the engine it will take 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 version of the assembly of electricalthe heat gun will make it possible to produce a small power device, but it will be enough 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.

repair of the heat gun by one's own hands

As for the assembly principle, it is not particularlychanges. 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. You will also need a combined fan, but it will be harder to find on the market.

Helpful Tips

Before you look for assembly schemes and buynecessary 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 big 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 great desire for yourhands to collect an electric heat gun, and for this there are all the necessary materials and conditions, then why not satisfy your interest? We recommend that you first consult with people who already have experience in assembling such heating devices.

Repairing the heat gun with your own hands is enoughIt is 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 by oneself. 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.
