How to choose a heat gas gun: the main selection criteria

The main advantages of gas heat guns include the highest efficiency and the use of environmentally friendly fuel, which is of great importance in the modern world. Natural gas is used as fuel, usually propane, which burns almost without residue, which gives the gun an efficiency close to 100%. One feature should be noted here - heaters of this type can operate both from a gas pipeline and from a cylinder

This is an important factor that you need to pay attention to when wondering how to choose a heat gun.

All models on the market have a common scheme of operation. Gas in liquefied form is fed into the working chamber, where it is sprayed with the help of nozzles, mixed with air and ignited. A piezoelectric element is most often used as an ignition device, which further increases the impressive list of advantages of this heating device, because it does not require electricity to operate. In this regard, gas heaters can be classified as "the best heat guns".

What are the best heat guns

Gas guns, depending on the principle of operation, can be divided into two classes - devices with direct and indirect air heating. Heaters operating according to the first option have a simpler device and a lower price. In them, the burner flame is not isolated, and the combustion products enter directly into the heated room. This design of the gas gun provides the highest possible efficiency, compact size, ease of manufacture and low cost. However, if you choose this type of device directly for residential use, good ventilation and a constant supply of air must be ensured.

Unlike the previous variety, gas heat guns of indirect heating, which have structural elements that ensure the removal of combustion products, can be used to heat residential premises on an ongoing basis. In them, the combustion chamber is closed, and the exhaust gas is removed using a special pipe connected to the chimney. The dimensions and cost of such a unit are significantly higher, because, among other things, to increase efficiency, it is necessary to equip it with a rather complicated heat exchange system.

Regardless of the design features of one or another option, during operation, the guns actively consume oxygen, which imposes certain restrictions on the scope of their application. This must be taken into account when choosing a heat gun of a certain variety. The room where such a unit is installed must be provided with a constant supply of fresh air, otherwise it is necessary to choose a model equipped with a thermostat that allows you to automatically control the frequency of switching on and off the device to maintain the required level of oxygen in the air.

Characteristics of heat guns

Another benefit of using a gun equipped with a thermostat is increased efficiency - the device will not idle when the room has already reached the set temperature. Depending on the field of application, gas guns can be equipped with a wear-resistant coating of the body or an anti-corrosion layer.The first is very useful if the device is used as a mobile heater, and the second will allow the device to be used in conditions of high humidity, for example, in greenhouses and greenhouses. In any case, the use of a gas gun as a heater will give the desired comfort in the room.

In general, based on the foregoing, only one conclusion can be drawn - a gas heat gun is a universal heater, which is easily used in almost all areas of human activity. And the question of how to choose the necessary heater of this class is solved by comparing the necessary tasks assigned to this unit and its technical characteristics.

What power to take a gun?

How to choose the right heat gun for houses by capacity? Power affects the size of the room the device can heat and for how long. There are average power calculations for the heated area. Usually, for rooms with a ceiling height of 2.5 m, the following ratio of power and area is taken: 100 W of thermal power is needed per 1 m2. For example, if you need to heat a garage with an area of ​​15 m2, you need to choose a heat gun with a power of at least 1.5 kW.

If you need to warm up a box with high ceilings, then it is better to calculate the power based on the volume / power ratio: 2.5 m3 = 100 watts. For example, you need to heat a box with an area of ​​30 m2 with a ceiling height of 4 m. Then you will need a device with a power of: 4 * 30 * 100 / 2.5 = 4.8 kW. So, you can take the Resant TEPC-5000K unit with a power of 5 kW.You should not take the power "for the future", because the higher it is, the more expensive the device.

And what heat gun to choose for stretch ceilings? In order for the film to clearly lie on the ceiling without sagging or stretching, it is necessary to evenly warm it up to 60 ° C. For a living room, bathroom or bedroom, a device of 3 - 5 kW is suitable. For unheated new buildings, it is better to take a gun up to 10 kW.

Number 3. Gas heat guns

Gas devices are equipped with a burner with holes through which the gas passes into the combustion chamber. When the fuel burns, heat is released, which heats the walls of the heat exchanger. The fan, as in electric guns, pumps air to the heat exchanger, releasing it from the gun already heated. The fan is powered by the mains, so you still need to connect to a power outlet, but the power consumption will be some 30-200 W, so this heating method will hardly affect your electricity bills.

The gas heat gun can work at the liquefied gas cylinder or be connected to a gas network. Ignition takes place manually or automatically.

Advantages:

• economy in operation;
• high efficiency;
• rapid heating of large areas and uniform distribution of heat;
• for the safety of the user, numerous mechanisms are provided, including overheating protection, flame control system, etc.

Minuses:

• despite all the safety mechanisms, a gas heat gun is more dangerous than an electric one.When burning, oxygen is used, and if the room is not equipped with normal ventilation, then the accumulation of combustion products and a decrease in the amount of oxygen will lead to sad consequences, so get ready to ventilate the room at least occasionally, or organize high-quality ventilation;
• connection to a gas pipeline or a constant change of gas cylinders is required.

These shortcomings fade before the main advantage of gas guns - the low cost of operation. Devices of this type are usually used for heating large premises: warehouses, workshops, industries, hangars. Often gas guns are used on construction sites when it is necessary that the mortars dry quickly or gain strength, and the room is cool and damp. However, small construction teams and private craftsmen do not need to go broke to buy their own equipment - in the cold season, to increase the efficiency of construction, installation and repair work, you can rent a heat gun. In Krasnodar, this service is provided by LLC Professional, which has been selling and leasing construction equipment since 2005. The range of gas heat guns can be found on the page all equipment is new and modern, and the company takes care of its maintenance.

The principle of operation of the heat gun

The principle of operation of all units is very simple. The fan forces air through the heating element or combustion chamber and throws heat into the room.

Even the smallest specimens are capable of driving up to 300 cubic meters per hour through themselves.

Pay special attention to the fact that any guns, whether diesel or gas, still require electricity.Some mistakenly think - I will buy such a thing for my garage, where there is no normal light, and it will immediately become warm and wonderful. No matter how

No matter how.

In any case, you will need 220V from a generator, or batteries with an inverter. You can't do without it. Fan, piezo ignition, security systems - all this needs to be powered by something.

The only convenient option for domestic use, where electricity is not needed at all, is infrared gas heaters.

But you can’t quickly heat large areas with them.

And guns, unlike other heating devices, the same radiators or convectors, are able to warm up tens of square meters of a room in just a few minutes.

The most important characteristics of such fan heaters are the power and the ejected air flow. They affect the rate of heating.

Criteria for a reliable heat gun

For a more visual acquaintance with a heat gun with a ceramic heater, consider the DHC 2-100, manufactured under the DENZEL trademark. Safety
We, as users, are primarily interested in the security level of the device. The DHC 2-100 has first class protection against electric shock. Most household appliances belong to this class: washing machines, dishwashers, food processors, and so on. The design has a built-in thermostat, which will allow you to set the required temperature in the room for automatic switching on and off of the gun. Protection against overheating will save you in critical situations - if the gun capsizes, it will be covered with something or a foreign object will block the fan.The front grille with a small cell will prevent accidental objects (as well as the fingers of curious kids) from getting into the heater area.

Heat gun with ceramic heater (fan heater) DHC 2-100 Possibility to select the heating mode
There is also a switch that allows you to select two power levels (1 or 2 kW) or a ventilation mode without heating at all. The power of the unit is sufficient to supply at least 100 m³ of heated air in one hour. At the same time, the area of ​​​​a reliably heated room is approximately 20 m². Maneuverability and mobility
Fixing the device to the supporting frame allows you to freely change the angle of its inclination. In passing, we note that for simple heating of a room, the most effective position of the gun is strictly horizontal. The weight of the heater does not exceed 2 kg.

No. 9. Heat gun dimensions

The higher the power of the gun, the larger it will be, which is not surprising. The most compact and mobile are electrical appliances. Household ones weigh from 3 to 5-7 kg, and some industrial ones reach 30 kg. Thanks to the wheels and the handle, such devices can be easily moved, the only limitation is the length of the wire.

Gas guns are also relatively compact and light, and if bottled gas becomes the fuel source for them, then everything will be fine with mobility. If you use the main gas, then any gun will become stationary for a while.

Diesel and multi-fuel guns are considered the most dimensional, since they also have a fuel tank. When it is completely filled with liquid fuel, the weight of the device increases.Moving a heavy liquid fuel gun is not easy, and if an indirectly heated unit is selected, then the device cannot be moved at all, because it is connected to the chimney.

In special cases, giant heat guns are used, the weight of which is estimated in tons. Naturally, such equipment is located permanently, since even its transportation requires special vehicles. Mainly used in production sites.

Scheme of gas supply in a gas heat gun

Gas inlet pipe Flame protection Solenoid valve Gas control valve Gas nozzle (nozzle) combustion head thermoelement Thermostat

After connecting the gas cylinder, the gas enters the gas inlet pipe (1), then into the flame protection chamber (2), the solenoid valve (3), into the gas supply regulator valve (4), into the gas nozzle (5), then ignition (ignition) is carried out from a spark plug.

The thermoelement (7) heats up and facilitates the passage of gas into the flame protection chamber (2). The thermostat (8) starts the electrical circuit and passes the gas through the solenoid valve. Also, the thermostat (8) is responsible for blocking the gas supply (protection against overheating).

Selection criteria

You can understand which heat guns are best for your home if you study their capabilities in more detail. The optimal solution for a dwelling, cottage or apartment is an electric model with a wall mount. The choice of heat guns for technical needs depends on the tasks assigned to them. For heating concrete, performing other construction work, gas or electric models are used.Infrared guns are used in the installation of stretch ceilings.

In this category, you can find mainly electric models. Gas options are the most economical, but they require a separate chimney or forced ventilation of the room, there are restrictions on the minimum area.

The main criterion for choosing a heat gun is its power. To heat a room with a volume of 30-50 m3 by 15 degrees, about 3 kW is needed. Twice as much will be needed for an object of 100 m3. Further proportions are preserved. In addition, on average, 1 kW of energy is required per 10 m2 of a house area - the higher the heat loss coefficient, the greater its consumption. It all depends on the thermal insulation of the object, its area and purpose. When choosing a heat gun for a home among diesel models, it is worth making a test run in order to better assess the quality of the equipment

It is important to pay attention to such moments

1. The presence of leaks, leaks in the area of ​​\u200b\u200bthe fuel tank. A leaky design poses a serious hazard.
2. Metal quality. If, after a few hours, soot appears at the attachment points, we can talk about too thin, low-grade raw materials. The heat capacity of the equipment will be extremely low.
3. The intensity of the flame exit from the nozzle. If the compressor responsible for its supply fails, the fire will be supplied too intensively, not allowing sufficient fire safety to be ensured. It is better to entrust the adjustment to specialists in the store. The absence of such a function is a reason for refusing to purchase.
4. After turning off the fan of the heat gun, it should work for some time for cooling. If it stops immediately, this can lead to the melting of components, sensors, and deformation of the case.

In cheap models, this function is not available, which often leads to device failure.

Number 3. Gas heat guns

Disadvantages of diesel guns - how to identify

When choosing diesel guns, pay attention to the thickness of the metal. In a low-quality product, after a few hours, the places where the fastening screws are located burn out

You can also check the quality of the metal by the color of the plate in the gun nozzle. For bad models, this plate heats up almost immediately after the flame is applied.

For more expensive ones, after a while. This clearly indicates that there is more metal there, and therefore more heat capacity.

With sufficient metal thickness, car heaters even manage to drill holes along the edges of the gun. They usually insert candles for calcination.

The temperature at the outlet of the nozzle of diesel guns reaches 400 degrees. And regardless of power. The difference is mainly in the volume of blown air.
For kerosene models, the temperature is even higher, by about 20%.

Not a single electric gun will give you such an output temperature.

What else should you pay attention to when buying? If the compressor responsible for the supply is incorrectly set, the flame from the nozzle will be prohibitive. This shouldn't be

Ask the store to adjust the unit. If it cannot be adjusted, it is better to refuse such a purchase.

In the event of an emergency shutdown and extinguishing the flame, check that the fan continues to operate. Otherwise, components may melt, sensors will leak, and the case will be deformed.

High-quality models are supplied with fine filters for diesel fuel. Thanks to this, the nozzle does not clog and works properly.

Cheaper specimens have a maximum of a small mesh on the fuel intake at the bottom. This is also explained by the difference in the principle of fuel supply.

Those with filters use a fuel pump capable of pumping diesel fuel through the filter. And the compressors simply do not have enough power for this.

Well, good models do not start right away. First, their automation system checks all the parameters of the sensors that are stuffed into this gun. Plus, the mains voltage is monitored, whether it is normal or not. Not to burn the fan.

Heat guns: Classification and main differences

Depending on the performance, heat guns are divided into domestic and industrial. Household equipment is usually designed for a smaller cubic capacity of the room and is more economical in operation. Heat guns for industrial use are suitable for heating large rooms or buildings with low thermal insulation.In addition, heat guns are very often used in the installation of stretch ceilings, where it is necessary to quickly heat the canvas before installation.

Depending on the energy source, heat guns are divided into several types.

Heat gun electric

Operates from a network with a voltage of 220 or 380 V. It is characterized by low power, small overall dimensions and is easily transported. The main advantage of an electric heat gun is the absence of combustion products and mobility. In addition, it does not require refueling and can be used to heat residential or small industrial premises.

Heat gun gas

It uses the energy of gas combustion to heat the heat exchanger. Such guns are usually more powerful, economical and do not require the removal of combustion products. Heat guns on gas need to connect a gas cylinder and periodically refuel. Can be used to heat rooms with a high degree of humidity.

Heat gun diesel

May have a closed or open combustion chamber. Diesel heat guns with an open chamber are used only in well-ventilated areas. Heat guns of indirect heating allow combustion products to be removed from the room by means of a corrugated pipe.

Waste oil heat gun

Multi-fuel thermal equipment. A waste oil heat gun is economical and suitable for heating garages, warehouses, industrial premises, where there is a large amount of waste fuel and lubricants.

infrared heat gun

Uses infrared radiation for heating. It can be used for heating solid objects, defrosting, efficient heating of work areas.Infrared heaters do not dry out the air, are safe and economical.

Heat guns with water heat source

They consist of a fan that blows a heat exchanger connected to a centralized heating system. Provide fast and uniform heating of the room. Characterized by high efficiency and economy.

How to choose?

Usually diesel heat guns are bought when electric or gas ones are not suitable for some reason.

The maximum power of the guns reaches 200 kW, which is a great value. They can be used in large industrial facilities. However, these models also have several disadvantages. They are quite expensive, and they also have high fuel consumption.

There is also an important requirement for good ventilation, because the exhaust of these devices is powerful.

When choosing a device, you need to pay attention to several nuances:

1. heating type. Diesel guns of indirect heating are very similar to gas installations. Fuel is supplied to the nozzle and burns in the chamber. Air is blown into the room, heating it. Only in this case the chamber is closed, which increases the efficiency of the device. But its cost is almost 2 times more than that of gas models.
2. Fuel used. Most heat guns run on diesel fuel and kerosene. But there are devices that need only a specific type of fuel. If you use diesel fuel, then more harmful substances are released into the atmosphere.
3. The heating power indicates how much heat can be obtained from the gun. The larger this value, the faster it can bring the temperature to the desired value. This indicator also depends on what area can be heated.
4. Warm air capacity gives you an idea of ​​how much warm air passes through the unit.
5. Possibility to adjust the temperature. That is, when a certain value is reached, the device turns itself off. For this, a thermostat is installed on it.
6. Power consumption. This parameter is relevant in order to understand how much electricity will be spent during the use of the installation.
7. Fuel consumption and tank capacity.

Where do you use indirect diesel heat guns?

In the garageIn stock

The air temperature near the diesel gun can reach 400 degrees at the outlet. This means that combustible elements must be at a distance so that an explosion or fire does not occur.

Thus, it is necessary to choose the installation, taking into account all these nuances. It must meet the requirements. It is recommended that you read the specifications before purchasing. But not always the user has sufficient experience. Then you can designate a specialist budget and tasks. He will provide a choice of several models that are able to cope with them.

Purpose and principle of operation

An important advantage of these heating units is the simplicity of design - they consist of a housing, a heating element and a fan. The shape of the body is cylindrical, but there are models in a rectangular design.

It is made of metal, which gives the device increased strength to mechanical stress and thermal changes.

Holes are cut into the body through which air is taken in. The body is mounted on a frame with wheels, as a result of which the whole structure is given stability and mobility.

The principle of operation of heat guns is quite simple.The motor-driven fan draws cold air through the slots in the casing and directs it towards the heating element. It uses a heating element or a spiral, as well as a combustion chamber together with a heat exchanger.

After passing through the heating element with a fan, the already heated air is blown out of the housing and distributed throughout the room.

In addition to heating apartments and private houses, the unit can be used for:

• heating garages, warehouses, gyms without a centralized heating system;
• drying the plaster applied to the walls;
• installation of stretch ceilings;
• stimulating the start of the car in cold weather.
