Operating principle and rules for choosing a gas heat gun

A gas heat gun is an adaptable device that offers effective and rapid heating for a range of uses. A gas heat gun can be a useful tool for drying paint, thawing frozen pipes, and warming up large areas. It’s particularly well-liked for outdoor events, workshops, and construction because of its strong heat output and portability.

The size of the space you wish to heat, the available power source, and the safety features all play a role in selecting the best gas heat gun. It’s crucial to take into account the kind of gas being used, the gun’s heating capability, and the integrated safety features to avoid mishaps. By being aware of these factors, you can choose a gas heat gun that best suits your requirements.

This article will examine the basic principles of how gas heat guns work, including how they produce and disperse heat. We’ll also go over important considerations for selecting one, so you can make an informed choice that ensures task efficiency and safety.

Design features

The operating principle of this class of units is no different from other heat guns: the combustion chamber body is cooled by air pumped by a fan. Then the warm air is directed to heat the room. Gas heat guns differ structurally from their electric counterparts only by the presence of a burner instead of a heating element (TEN). Gas ignition occurs automatically using a piezoelectric element. This device can be used both for residential premises and for heating industrial facilities. For example, a high-performance gas heat gun with a power of 10 kW can heat a room in a new house with an area of ​​150-300 sq. m. or a greenhouse up to 70 m 2 . If the gun has a power 10 times greater, then it is capable of efficiently heating a building with an area of ​​​​about 3.3 thousand square meters. m or greenhouse – 740 m 2 . One cylinder of propane gas is enough for about 60 hours of operation without stopping, while it should be taken into account that the fan heater turns off automatically when the set temperature in the room is reached, and then turns on if the temperature has dropped. For autonomous operation a gas cylinder with liquefied natural gas is connected to the product, which can be easily replaced as it is used.

When used to heat a living space, a small heat gun that runs on natural gas uses no more than 1 liter per hour.

Construction sites, warehouses, and workshops are the perfect places for a gas heat gun because it is a strong instrument for rapidly heating large areas. It works by burning gas to create hot air, which is subsequently expelled by a fan to heat the surrounding area. Think about things like power output, fuel type, safety features, and the size of the area you need to heat when selecting a gas heat gun. Knowing these factors will assist you in choosing the best model to meet your needs and guarantee safe and effective operation.

Classification of products

• products of direct heating of the air flow;
• indirect heating units.

When it is utilized to heat the air flow in the first instance The combustion products from an open fire that burns propane gas fall into the heated room, but this design maximizes efficiency. Such a device has very small dimensions and is inexpensive, but ventilation is required to ensure that fresh air is constantly flowing. High fire hazard: No inspector will certify that this device is safe to use on residential property.

The second option is better since all combustion products are released through a dedicated pipe that is connected to the chimney because the unit has a closed combustion chamber. It is preferable to install these devices outside and use a specialized system with a large-diameter, non-flammable sleeve to pump warm air.

Propane, which burns cleanly and eliminates the need for combustion product removal, powers modern gas heat guns that indirectly heat the air flow. The only difference between them and direct heating devices is their size, which translates into a higher cost.

Requirements for use

No matter how well-designed a product is, stable combustion necessitates a steady supply of oxygen from the surrounding air for it to operate. These features must be considered by the user when choosing a model.

Pricing is determined by factors such as size, power, and brand: a gas-fired heat gun will cost more if the operating conditions are more challenging and there are more heated areas.

The room where the unit is planned to be located must have excellent ventilation, so that there is a constant influx of fresh air from outside. If there is no ventilation, then you need to choose a model with a thermostat that automatically turns off or turns on the gun, maintaining a sufficient level of oxygen. Equipment with a thermostat allows you to increase the efficiency of the product: when the optimum temperature is reached, it turns off the fan heater, turning it on only when the set temperature drops to a certain level. Products of this class are used in production, in warehouses, in the construction of buildings and heating of agricultural facilities, where people are not constantly present.

Choosing a unit

The entire line of gas products operates with extremely high efficiency, and it’s also important to note that they are environmentally friendly. Burning gas does not pollute the atmosphere, and there are no unnecessary odors, which is crucial for farmers who raise vegetables and flowers.

How do I pick a gas-fired fan heater from the many models that are on display? You must gain more knowledge about the blue fuel that is used, the unique characteristics of heating units, and the device in order to make an informed decision.

1. It should be taken into account that similar heaters operate successfully from the main line or from a cylinder connected to a gas heat gun . The efficiency of such a device becomes almost 100%.
2. To purchase the desired product with effective performance, you need to calculate in advance what power unit you need. Made room measurements: you need to know its volume. You should also check the quality of the thermal insulation, whether there will be leaks. The higher the performance of the heat gun, the faster it will heat the room to the desired temperature.
3. Pay attention to gas consumption, to know how long the gun will work without the first shutdown.

We have already gone over the workings of the operating circuit for all gas fan heaters in detail a little earlier. It is important to highlight that since the piezoelectric element can ignite gas without electricity, many do not require a network connection.

Experts believe that the TPG-10 kW for 7,000 rubles is the greatest choice for locations without a nearby electrical connection:

• works on propane and butane;
• performance – 300 m3 /h;
• temperature up to + 90 C °;
• gas consumption max – 0.76 kg / h;
• weight – 5.5 kg.

This gas heat gun can be used in locations with network connections and without electricity, either directly from a gas main or with a connected cylinder. Similar benefits apply to the Sturm GH91101 product, which has a 10 kW power output, 0.75 kg/h consumption, 330 m3/h productivity, and a mere 5590 rubles in cost.

To prevent permanent damage during self-service, experts strongly advise users to repair gas heat guns only in designated centers with gas equipment technicians.

Models in demand

We will only look at the most widely used gas gun models available on the Russian market today, including Master, Ballu, and many more.
