How to make a heat gun with your own hands

The heat gun is made with their own hands very quickly. It is only necessary to prepare various materials in advance, choose an acceptable type of heater, and on which it will work: electricity, gas or various types of fuel.

Briefly about the classification

The difference of guns is depending on the type of fuel on which these heating devices work or on the method of heating the air flow. Hence the names:

• electric gun;
• diesel;
• gas;
• infrared type heating elements;
• water;
• monofuel.

First of all, we are interested in how to make a heat gun working from the networkbecause it is the most common and safest option. Simple maintenance, no need to check the presence of fuel in the tank, environmental friendliness.

Functional features

When you do not have the material opportunity to purchase a patented factory-made apparatus, a home-made heat gun is the only way to fulfill your plan for repair or construction.

The principle of operation of such a unit is simple: in a pipe made of asbestos or some metal, tena are installed or a spiral is arranged in a special way. On the one hand, a powerful fan is inserted, which injects air into the pipe, where it heats up and is released through the opposite opening into the room.

Such electrical devices really quickly heat up rooms of various sizes. It all depends on power of heating elements: the more powerful, the faster the optimum temperature is created. There is only one negative point - this is a large energy consumption and rapid drying of the air. When used in a residential area, an open container with water should be placed next to humidify the air.

A heat gun with its own hands is often made by garage craftsmen to heat these rooms in winter.

Electric gun

Before proceeding to the manufacture, a detailed electrical circuit of the device is made, all the components are assembled.

Electric gun

To make a heat gun with your own hands, you will need the following materials:

1. Asbestos — zinc tube large diameter to enter the fan. Some people prefer to make the case of galvanized metal with a thickness of at least 1 m, and the whole improvised device turns out to be more mobile.
2. Electric motor and an impeller for assembling a fan - can be purchased in stores or assembled from improvised material, for example, using an old fan and a motor from a vacuum cleaner.
3. Heating elements can be made of special wire, winding it on the electrode. It will turn out to be a spiral, as for a hotplate, only it is necessary to make preliminary calculations, otherwise such a gun can cut out the light in the whole area.
4. Purchase or pick up ceramic insulators, copper wire with a cross section of at least 2 mm, fuses for 24 A, wire connection with a plug and other trifles.

Only after that we begin to collect the electrical part according to the previously drawn scheme. An electric heat gun is assembled as follows:

• prepare the body and support with an insulating lining;
• we stretch the spiral in the form of a star and fasten it inside the case,or install the tenes in the center of the pipe;
• we connect to the terminals of the power wire;
• we fix the fan, we bring the wiring;
• install protective grilles on both sides of the case;
• we mount the control unit and connect all the wiring to it;
• Install the wire connecting the device to the network.

All connections of the electrical circuit when assembling a heat gun carefully isolate - everything is done by hand, so we pay special attention to detail. After completing the work, we do a test run: the system works normally, which means that the product can be operated without fear.

Attention! When assembling, special attention should be paid to safety: the metal body of the pipe should be protected with an asbestos lining on the basis so that a fire does not happen, and all wiring is carefully insulated.

Diesel heat generator

Sometimes, not only in order to save, but when there are no near sources of electric current, a gun on diesel fuel comes to help in heating the premises. Its principle of operation is fundamentally different from electrical analogs, however, and the design too. Before you start making, you need to get a drawing, carefully study it,and then collect all the details. The simplest diesel heat gun of indirect heating has the following main parts:

1. Cylindrical body made of durable metal.
2. Tank with fuel, transfer pump and filter element.
3. The combustion chamber from thick metal with one or several nozzles for spraying diesel fuel.
4. Fan for forcing air.
5. Chimney pipe for discharge of combustion products.

Diesel heat gun begin to collect from the installation inside the main body of the fan, then insert the combustion chamber and center it. Connect the fuel piping system from the tank and transfer pump to the nozzle. The fuel tank in the whole structure is located at the very bottom, it does not have direct contact with the pipe body for fire safety reasons.

It is necessary to take a container for a diesel heat gun, although you collect everything with your own hands, this is a guarantee of safety.

Near the pump is fixed and fine filter. The pump is connected to the nozzle via a copper tube. Inside the combustion chamber is placed factory piezo element for ignition of the sprayed fuel.At the top of the chamber, a discharge pipe is made through which all products of combustion are removed to the atmosphere. On both sides of the case are installed protective grilles, in order to exclude the careless touch of the hot end of the combustion chamber and to protect people from the working fan.

Making a diesel engine yourself is not as easy as it seems at first glance. If you do not have enough knowledge, it is better to buy the factory version - the guarantor of fire safety.

Gun on oil

Some garage masters make devices on waste oil with their own hands, but why reinvent the wheel when there are factory settings that are allowed for use in any premises. They work on any hydraulic or motor waste product that can be purchased inexpensively.

A heat gun with waste oil made by a garage worker will be much cheaper, but what about safety? Who will answer if something happens with the installation working on oil processing? In the factory version, all the combustion products are discharged through the pipe to the outside, and in an improvised unit, the oil often burns in a dirty cup from a blowtorch aimed at it.The factory version has an efficiency of 100% and burning oil does not violate the ecology of the room, which cannot be said about handicraft production.

Gas heat generator

The principle of its operation is identical to the diesel variant, and the gas heat gun is assembled in the same way, but instead of diesel fuel is supplied gas. It has a high degree of fire danger, because there is open fire inside the case. Such devices can be purchased in the corresponding outlets at a price of 5.1 thousand rubles. - they are checked by the fire inspectorate, there is a certificate allowing use in various premises.

Made in an artisan way, the unit inspires little reliability, it makes noise and smokes in different modes, and open fire inside an unopened pipe does not add security. In addition, there are no guarantees for burners, often made in China.

To repair the factory version, you just need to contact the service center, where specially trained craftsmen will solve all your problems. A handicraft device in the event of a breakdown of the main parts will be much more difficult to reanimate, if at all possible. About his work can be judged by the video.

Self-made gas guns are powerful very dangerous devices, where there is no protection against overheating, and there is no control over the flame. They cannot be left unattended for a minute.

The device gas generator

Many users believe that it is not so difficult to assemble, let alone repair the heat gun with their own hands. This is not the case - without special knowledge and technical skills you will make a makeshift semblance of a heat generator. Remember that the electric gun you made is the source electrical injuries, short circuits, if by any chance a simple error was made during assembly. Other species, especially with open fires, are sources of imminent fire.
