The choice of a gas heat gun for a garage, other premises, stretch ceilings. Heat guns Indirectly heated gas heat guns

Gas heat gun used for heating, drying and ventilation of non-residential premises. The unit runs on liquefied (butane, propane) or natural gas and is used in large rooms as the main source of heat and an additional one.
Any diesel or gas heat gun will be effective at such facilities as warehouses, construction sites, hangars, storage facilities, production facilities. Due to the emissions of fuel combustion products that are harmful to humans, it is not recommended to use these units in living rooms, houses, offices and other places where people constantly stay without proper air ventilation.
The design of the gas cannon consists of a heat exchanger, where the gas is burned, and a powerful fan, which creates a directed air flow. Durable metal housing protects internal parts. Typically, cannons have an automatic ignition or piezoelectric system, as well as an effective safety system that controls the size of the flame.
Gas cannons have a simple principle of operation - gas from a cylinder or gas pipeline is fed into the combustion chamber, where it is ignited by an automatic or piezoelectric element. When the gas is burned, the heat exchanger heats up, which transfers its heat to the air stream coming from the fan. The heated air is dispersed throughout the room.
Some models of gas cannons use infrared heating. There is no fan in this design, but there is a reflector (special screen) that heats up the gas burner. The reflector transmits heat in the form of infrared rays to surrounding objects, which, in turn, reflect this heat and heat the room.

Varieties of gas heat guns Heating principle gas cannons are divided into:

direct fired gas cannon- when gas is burned, combustion products are emitted directly into the room where it is installed. This gun has a simple design and high efficiency. This type is the most harmful to humans and can only be used in places where there are no people: hangars, construction sites (when drying walls after painting), etc.
indirect gas heat gun- removes combustion products through the chimney connected to it to the street. This type is safer and can be used in rooms where people are not constantly staying. Cons: lower efficiency and the need to lay a chimney.

Also by type of construction allocate:

mobile gas cannons;
stationary.

Mobile models are compact and usually have 1 or 2 pairs of wheels and a handle for easy transportation around the room. The power of the guns during heating is in the range of 10-100 kW and they use gas sparingly. The price for such gas heat guns is affordable; anyone can purchase this model. Such a mobile gas heat gun for a garage is perfect. When operating a mobile cannon, be careful with the use of gas.
Stationary heat guns are large and are installed or mounted in one place, for example, on the ceiling. The maximum thermal power of such devices is 580 kW, and the productivity of heated air is up to 40,200 square meters per hour. They can heat large rooms in a short time.

Key parameters when choosing a heat gun

Power. The size of the room, which will be heated or ventilated, depends on this value. The power is calculated based on 100 W per 1 sq. m. For large objects, as a rule, high-power industrial heat guns are used, which consume a lot of gas.
Fuel consumption. This indicator depends on the power - the higher it is, the faster the gas will be consumed. The maximum flow rate is 305 liters per hour. Fuel for gas cannons is supplied from a gas pipeline or from cylinders.
Weight. This indicator is directly affected by the power - the higher it is, the more gas is consumed and the thicker the walls near the combustion chamber. Mobile gas cannons can weigh from 4 to 60 kg, industrial - more than 60. Wheels are provided for convenient movement.

Air heating is good because it does not require installation. One of the most popular options for utility and industrial premises is a gas heat gun. This device quickly warms up the air, however, it cools down just as quickly when the gun is turned off.

Device

It is no coincidence that this heating device is called a cannon: it is a cylinder on a support, more massive models have wheels for easier movement. Compact models are equipped with a special carrying handle. During operation, the case heats up to solid temperatures, so you shouldn't touch it.

Direct heating gas cannons device

A fan is located in a cylindrical casing, behind it (closer to the "outlet") a burner. Air is sucked in from the back of the housing and passes through the fan, blowing over the burner. Gas is supplied to the burner, which is ignited by ignition. The gas mixes with the air stream, which contributes to its more complete combustion.

A good quality gas heat gun is designed so that even at the highest power, the flame does not go beyond the body. There should only be a stream of hot air at the outlet. As you can see, the device is not too complicated and the principle of operation is simple. The design is complemented by filters - air and fuel, various sensors and safety devices.

Indirectly heated gas cannons

The main disadvantage of the above design is that the combustion products remain in the room. Understandably, this negatively affects well-being and, as a result, on health in general. But this option has a very high efficiency - 95-98%. Therefore, it is these models that are chosen in production or for temporary use.

There are gas cannons without exhaust. Rather, the exhaust is removed from the room through a pipe. The device of such models is more complex. The combustion chamber is the same cylinder, only it is sealed to the room. In the upper part it has an outlet pipe through which combustion products are removed. Heating occurs due to the fact that the air driven by the fan blows the combustion chamber, taking heat away from the walls. Therefore, these models are called indirect heat guns. First, the heat exchanger heats up, and from it the air.

To make the heat selection more complete, the gas from the combustion chamber moves through the labyrinth. Thus, the efficiency increases, but this indicator still does not rise above 80-85%. But such installations do not harm health, they can be used on a long-term basis.

At the moment, the range of indirect gas cannons is very scarce, and the prices are high. First of all, these devices are focused on large production and storage facilities.

Gas gun of indirect heating Ballu JUMBO 200 T LPG. Maximum power - 220.9 kW, price - 512,000 rubles

Advantages and disadvantages

Let us remind you once again: the gas heat gun is not intended for use as permanent heating. It is great for quickly warming up a cold cottage, garage, etc. It showed itself well when heating buildings under construction. It can be used to accelerate the drying of plaster and other mixtures (where technology allows). But it is not worth using the unit for constant heating of a residential building.

Now the cons:

Burns out oxygen, so good ventilation is essential.
Officially filling the bottle is problematic (it is prohibited at gas stations);
The expense is high.
If the cylinder is cold, it burns badly.
Some models make a lot of noise.
Electricity is required (for the fan to work).
The temperature in front of the nozzle of the working gun is very high.
With half the gas in the cylinder, problems can begin: it often goes out. But this problem is typical for small cylinders. When using 50-liter, everything is fine.

As you can see, it is far from ideal. But for the quick removal of premises from sub-zero temperatures to positive temperatures, it’s not bad at all. For example, having arrived at a dacha that is heated by a stove, do not freeze while it warms up, but turn on the gas heat gun and after 15-20 minutes you can undress. There might be an alternative, perhaps. It is for a summer residence that it is possibly better, but you have to think about a garage and other technical premises.

Power selection

To roughly estimate the required power of heating devices, they are considered by area. For a detached building in the Middle Strip, 1 kW of heat is required per 10 square meters of area. The gas heater is not designed for permanent heating. Usually it is taken to quickly warm up a technical room, a summer cottage, a garage, etc. Other devices are more commonly used to maintain the temperature. For this reason, traditional area or volume power calculations are not appropriate.

The formula for calculating the required power does not change:

V is the volume of the room (multiply the height, width and length):
dT is the temperature difference that must be provided (consider the difference between the "starting temperature" from which you will start heating the air to the one you want to have in the room);
Kt - coefficient of thermal conductivity of walls, floors and ceilings. With good insulation from 1 to 2; with poor thermal insulation from 3 to 4; with excellent insulation from 0.6 to 1.
860 - kilocalories per 1 kW of heat.

It's easy to calculate. Let's give an example. A gas heat gun will heat up a garage with dimensions of 5 * 3.5 m, with a ceiling height of 3 m. The walls are one and a half bricks, only metal gates are insulated. It is planned to increase the temperature from -10 ° C to + 20 ° C. We substitute the initial data into the formula, we get:

In total, we got that this room can be heated by a heat gun of 4.6 kW. But heating will last at least an hour - the formula is so built. If you want to shorten the time, the power must be increased proportionally. If the time is halved (in 30 minutes), we multiply the power by two, in order to warm it up in a quarter of an hour (15 minutes), the found power must be multiplied by 4:

in 30 minutes they will warm up 9.2 kW;
in 15 minutes - 18.4 kW.

The above calculation is approximate, but it allows you to estimate the required parameters. For those who do not like to count, there are tables in which everything has already been calculated. But they are given "on average" without taking into account the peculiarities of your buildings. The necessary parameters will have to be taken into account by ourselves, choosing from the proposed "fork" of capacities.

Criterias of choice

Power is far from the only parameter that determines the choice. The gas heat gun still has a sufficient number of characteristics that are worth paying attention to.

Protective functions

Open fire and gas are a dangerous combination. In the case of a gas fired heat gun, the possibility of carbon monoxide poisoning is also added. So additional security measures are not superfluous at all. Here are some of the protective mechanisms this equipment can have:

Overheating protection of the electric motor. The temperature of the fan motor is monitored. When critical values are reached, the gas is shut off. Restarting is possible only after the engine has cooled down.
Flame control. If there is no flame on the burner, the gas supply valve is closed.
Protection against gas leaks. There is an atmospheric air analyzer. If the CO content is exceeded or the amount of oxygen is insufficient, the equipment is turned off.
Roll-over control. When the position is changed, the gas supply is cut off. So even if the heat gun falls, a fire is unlikely.

The only thing that can raise doubts is air control. Since the sensor is built-in, the condition in the immediate vicinity of the device is analyzed, which can distort real data. Therefore, it is better to have a separate detector. Detectors (sensors) are inexpensive and can be programmed.

Performance characteristics

Power is far from the only parameter that characterizes the operation of gas heat guns. There are a few more that are simply necessary to understand how efficiently the unit will work.

As you can see, there are quite a few parameters. Not all are obvious, some can be missed, but in general, pay attention to them.

Ease of use

Despite the fact that outwardly one heat gas gun is practically no different from another, it is convenient to use some, others not. This can be tracked by the following criteria.

Once again, we draw your attention to the fact that the gas heat gun is intended for rooms in which people are not constantly. With sufficient power, it will very quickly heat up the air even in a frozen room. But after turning it off, everything cools down just as quickly: only the air has heated up, and not the walls and other enclosing structures. However, as a means of rapid heating, it is very efficient (although it uses a lot of fuel).

Manufacturers

The most difficult thing to buy is not the choice of power or characteristics. This is, of course, important, but more important is the quality of the equipment. And it often depends on the manufacturer. Gas cannons are no exception. Few will agree to spend too much money on this equipment - the option is temporary. Usually they are chosen according to the criterion of price / quality. "Half-Chinese" fit into this category. These are those who have management in Europe-America, and production in China. Russian gas cannons are in about the same category. Here is a list of popular brands:

This is not to say that all models of the above manufacturers are successful. There are very good ones, and there are - quite "so-so".

Stretch ceiling guns

Despite the fact that it is safer to use electric heat guns when installing stretch ceilings, direct heating gas models are more popular. This is due to the fact that gas cannons have higher power and efficiency.

As a rule, professional "ceiling loaders" have guns of different power in their arsenal - for different ceiling areas. If we are talking about rooms with an area of up to 20 m², then a heat gun with a capacity of about 15 kW is sufficient. For example, Master BLP 17 M (16 kW) and Ballu BHG-20 (17 kW) are suitable. In small rooms it is more convenient to work with compact guns. In terms of safety, many experts recommend using composite cylinders.

If a more versatile option is required, then a direct heating gas cannon with a power of 30-50 kW will be optimal. For example, RESANTA TGP-30000 (30 kW) or Master BLP 33 M (33 kW).

In particular, a gas cannon is actively used for space heating, which has sufficient potential to maintain an optimal temperature regime for a large space. But such a unit must be chosen correctly, focusing on the technical characteristics and scope, otherwise it will not bring the expected effect. Moreover, you have to make a choice between:

Liquid fuel devices,
Gas units,
Electric models.

If the facility is just being erected and it is necessary to provide drying of the walls and maintain normal conditions for construction crews working in the premises, then gas-fired heat guns using natural gas will be quite suitable, as well as diesel models.

The advantages of this heat gun

What you need to consider if you decide to make the choice of a gas heat gun? These are the capabilities of this equipment and its technical parameters. Of the advantages of such units, it can be noted:

High performance,
Environmental friendliness,
Waste-free combustion of the fuel used.

So a gas cannon for space heating can be quite suitable as an environmentally friendly and efficient piece of equipment. Natural gas, which is used for such devices, is able to burn without residue and provide an absolute efficiency. The operation of this equipment is possible both from gas pipelines and from portable cylinders.

The principle of operation of cannons on gas

If you read reviews of gas cannons for heating rooms, then some users do not quite understand how such units work, which significantly complicates repair work if the need arises.

The liquefied fuel is fed into a special chamber, where it is sprayed and mixed with air masses. And if you plan to repair the master gas cannons, then you need to check the ignition system, which is based on the piezoelectric element, it is he who makes the equipment of this type independent of external energy sources.

Direct and indirect air heating

When a gas cannon of indirect heating is selected, then all combustion products formed during operation must be forcibly removed outside, and a dangerous concentration of toxic elements will not arise in the room. Heating of residential premises is allowed with such equipment, and the process can proceed in a constant mode.

It can be considered that these are the best gas heat guns in terms of safety. They have closed chambers in which the natural gas combustion process takes place, and the waste materials are removed through a special pipe.

But there is one negative factor for these units - it's high cost. And if we analyze the gas heat gun interskol tpg 30 reviews, it turns out that such equipment is not available to everyone, and repairs are too expensive.

Direct heating is done with an open burner and the combustion chamber is not closed, so that heat and combustion products enter the room. And this factor makes it dangerous to use such devices in residential premises. But on the other hand, you can always repair a gas gun with your own hands, if it is of direct action, since the design of such equipment is much simpler.

Design and principle of operation

As part of our reviews, we have already considered productive heat guns that run on liquid fuel. They have high efficiency, but they are sources of an unpleasant odor, since the fuel in them does not burn 100%. An alternative to them is gas units operating on natural or liquefied gas (liquefied gas is most often used - we will explain a little later what this is connected with).

A gas cannon for heating premises is a relatively simple unit in terms of internal arrangement, which uses gas for its power supply. By burning the incoming fuel, this unit generates a large amount of heat, which is sent to the room using a powerful fan. The heart of the device is a burner with an ignition system - simple piezoelectric elements and electric ignition systems with electrodes are used here.

The gas cannon device is as follows:

Thermostat - provides temperature control;
Fan - it provides the burner with oxygen and sends heat to the heated rooms;
Control system - includes a thermostat and a start button;
Burner - a module equipped with a nozzle and providing a flame torch.

In some models of gas heat guns, there are also heat exchangers - they serve to safely transfer heat to heated buildings and premises.

A gas cannon cannot work without electricity, since its essence is to "shoot" heat under high pressure, characterized by high performance. Without a fan, it would turn into the simplest burner that cannot boast of high efficiency. Therefore, it is almost impossible to find units that can work in a completely autonomous mode - a power source is required here.

The gas-fired heat gun is enclosed in a solid metal case and in all its appearance really resembles some kind of weapon that shoots cannonballs. Only, instead of cannonballs, hot air escapes from its throat. Due to the built-in fan, the heated air masses are evenly distributed over the heated volume. Thermostatically controlled models track the generated temperature for precise temperature control.

To power gas heat guns for residential premises, two types of fuel are used - this is main gas or liquefied gas from a cylinder. In the first case, everything is not so simple, because you need permission to connect to the backbone. Therefore, most often, liquefied fuel is used to power the units. The gas cylinder for the heat gun is the same cylinder that is used in conjunction with conventional kitchen stoves. Its volume is not limited in any way, the connection to the heat guns is carried out through a pressure reducer to reduce the pressure.

Appointment of heat guns

Heat guns are most often used to heat non-residential premises - these can be various hangars, production workshops, buildings and warehouses being renovated. At the same time, at the time of work, people may be there if adequate ventilation has been provided. As for living quarters, here they are used much less often - after all, less bulky and more accurate heating devices with a low noise level are more suitable for living rooms.

In residential premises, heat gas cannons can be used during repair and finishing work. With their help, the plaster is dried, the temperature is increased for faster drying of concrete screeds. They are also used in the installation of stretch ceilings - a relatively high temperature is needed here, which is required to stretch the web. And thanks to the directed heat flow, builders have the opportunity to carry out spot drying.

Main varieties

All these units are divided into two broad categories - direct heating and indirect heating.

Directly heated rafters send combustion products to heated rooms along with hot air. They are not toxic, but it doesn't make it easier to breathe. But such units are characterized by high efficiency. Good ventilation is required for their operation; operation in closed buildings and structures is prohibited.

An indirect gas cannon is a more advanced, but more complex unit. Here, a closed combustion chamber is used with the removal of combustion products to the outside through the chimney. Blowing over the combustion chamber, the fan drives clean warm air into the room. True, such heat guns are very rare on sale, and their cost hits the buyer's pocket hard.

Heat gun launch

As we already said, gas heat guns are powered by a gas cylinder (mostly). The startup process looks like this:

We fasten a reducer with a hose to the gas cylinder;
We connect the hose to the heat gun;
We connect the unit to the electrical network;
Press the start button and set the desired temperature.

The fan will turn on, the igniter will work (in some models, the gas is ignited by a button with a piezoelectric element) - and after a few seconds, the room will begin to fill with warm air.

Advantages and disadvantages

Let's see what are the pros and cons of gas heat guns for heating residential and non-residential premises. Let's start with the positives:

Efficiency - for example, for a 30 kW heater, the gas consumption per hour will be slightly more than 2 kg;
There is no strong smell of combustion products - the fuel burns out almost completely;
Comparative diminutiveness - unlike diesel units, there is no tank here.

Negative traits:

Insecurity - this trait is inherent in all gas appliances, including kitchen stoves;
The need to use electricity - at facilities without electrification, you will have to use a generator;
Difficulty connecting to the backbone - this requires a special permit.

Nevertheless, gas heat guns continue to be in demand equipment, especially in the construction industry.

How to choose the right heat gun

If you are going to buy a gas heat gun, focus on its performance and power, comparing these parameters with the heated volume. Remember that for every 10 sq. m of area requires at least 1 kW of heat. If you plan to use the unit for construction purposes, for drying plaster or installing suspended ceilings, you should choose a more powerful model.

Remember that the higher the power, the higher the noise level and the higher the gas consumption. If the task is to heat a small basement, cellar or greenhouse with a heat gun, choose small-sized models - they are somewhat similar to ordinary fans. For heating large hangars and warehouses, more efficient units will be needed. If people work in the premises and there is no ventilation, take a closer look at indirect heating heaters.

Another selection criterion is the manufacturer. If you choose between domestic devices and foreign ones, then you will not be able to give special preference to someone. Russian and foreign brands make good gas heat guns characterized by endurance and good technical characteristics. But if we turn to the ratings, then they are headed by the Master brand.

Popular models

Enough theory - let's get down to practice. Now we will consider the most popular models of gas heat guns. All of them are direct heating models.

In order to extend the life of the unit, the manufacturer has endowed it with overheating protection. As soon as the excess of certain indicators is recorded, the equipment will turn off the gas supply and resume it after cooling down. Also, the heat gun provides for the protection of the body from the effects of corrosion - for this, the body is covered with a special coating. The heat gun is distinguished by its unpretentious operation and efficiency - it burns only 2.27 kg of gas fuel per hour.

Low cost - it is about 5,000 rubles;
Gearbox and robust hose as standard;
Reliable and durable burner with ignition protection at low gas pressure;
Complete shutdown in case of power outage;
Almost complete combustion of fuel.

There is no electric ignition here, a simple piezoelectric element is responsible for this. Also, the heat gun is equipped with overheating protection.

The heat gun turned out to be compact - its dimensions are 435x230x305 mm. It is a great choice for construction crews and anyone looking for a portable gas heater with decent performance. The official cost from the manufacturer is 4499 rubles, which makes this heat gun one of the most affordable devices.

What is a heat gun

The demand for such a modern unit increases several times during the heating season, provided there is no central heating or its poor quality supply. Gas heating cannons emit warm air, which is formed by burning gas. Outwardly, it is a streamlined metal body with a hole for the exit of a hot stream, but inside the structure is somewhat complicated and is represented by the following elements:

burner;
fan;
heat exchanger;
ignition device;
control device;
thermostat;
additional devices depending on the design features.

Types of gas cannons

Before making the final choice, it is important to find out what types of designs exist, which option in a particular case is optimal. A gas heat gun is very popular, it is necessary for heating and ventilation of living quarters, for drying bulky items. The range is wide, but the classification provides only two design features - direct and indirect heating. Both options are suitable for domestic needs, but have a different appearance and principle of operation.

Direct heating

In such a design, the purification of air streams from burning does not occur, so they all collect in the living room, poison the oxygen. Direct fired gas cannons are required where there is sufficient natural or artificial ventilation. This is the main disadvantage of the gun, but 100% efficiency, minimum energy and fuel consumption remain significant advantages.

Indirect heating

The annular heat exchanger acts as the main heating element, which operates according to this principle: first, gas is burned, then poisonous products that are released during the formation of fuel. The indirectly heated gas heat gun is an environmentally friendly device, so its installation in a room is possible even with limited ventilation. The disadvantage of the mechanism is the presence of a chimney, which complicates the mobility and transportation of the gas-type cannon.

How does it work

Before using the gun at home, you need to understand in detail how it works, how it functions correctly, which manufacturer is the best in a given direction. This greatly facilitates the final choice of a suitable design and simplifies the operation process. The principle of operation of a gas cannon is as follows:

There is a special burner in the combustion chamber, where the gas flow is fed.
With the help of the ignition device, the gas burns, the heat exchanger heats up.
The fan blows cold air from the environment, directs it through the heat exchanger.
A specially inserted thermostat protects the unit from overheating and breakdown.
The presence of the switch breaks the electrical circuit when the room heats up to the desired reading on the thermometer.

Gas cannon device

Such a home heater is used for domestic needs, and the preference of modern buyers is given to mobile types of gas "burners" with wheels and control knobs. Stationary cannons are equipped with a gas cylinder, which is problematic to transport. The duration of operation of the unit itself and its technical characteristics depend on its volume. Such a stationary design of an indirect blown gas cannon is considered morally obsolete, impractical to use, mobile models in the range are more in demand.

Gas heat gun

This is an independent heating device and a structural component of a heating installation, which is necessary to maintain the required climatic conditions in a residential area and not only. The natural gas heat gun can be used to heat automobile and special equipment, it will be useful in the repair process and for installing stretch ceilings. The presence of the fan allows to speed up the technological process, and the built-in thermostat controls the heating of the air flow. The cannon runs on gas, a suitable model can be ordered in the online store.

Propane Cannon

It is also called a thunderbolt because you can hear a loud bang during operation. If the previous model operates on gas, then the specified unit has its own design features. The propane heat gun is an environmentally friendly device, often used to scare away birds and wild animals. Among the advantages, experts point out simplicity of design, lightness and economy.

Application

Such gas-fired equipment is in demand in everyday life and at work, and has found widespread use among the masses. This is not only quick heating of residential and non-residential premises, but also drying of individual items for automotive and industrial purposes. In addition, the use of a gas cannon is appropriate for large areas - from 25 sq. meters, during repair work, for example, when installing stretch ceilings.

These non-residential premises are characterized by dampness, which only interferes with the storage and safety of a personal vehicle. To dry the walls and remove fungus from far corners, it is recommended to use garage gas cannons. The purchase is not cheap, but the unit can additionally be used at home and in the country. It is important to take into account such parameters as the size of the garage, the quality of thermal insulation, the mode of presence of people in such a non-residential premises. There are two options for choosing guns:

The gas cannon can be used when there are no people in the room. The unit provides high operating power, fast heating of the garage, minimum energy costs.
A diesel cannon is appropriate if people are or live in the garage. Due to the presence of an exhaust pipe, combustion products are efficiently removed and do not settle on the walls.

For heating living quarters

Considering the comparative characteristics described above, it becomes obvious that stationary direct blown structures are not suitable for heating the specified space. A gas heat gun for residential premises must be equipped with an exhaust pipe so that combustion products do not linger in the living room. In addition, it is important to obtain high efficiency with minimal energy consumption.

For stretch ceilings

When carrying out repair work, this unit is also needed. A gas heat gun for mounting stretch ceilings is an indispensable "tool", because when PVC film is heated up to 65 degrees over the entire surface, it makes it elastic and pliable. The material easily falls on the ceiling, is firmly attached to the pre-prepared gaps. If a gas cannon is turned on when performing this type of work, condensation does not accumulate on the base plate during fixing of the PVC film. This is one of the important advantages of the participation of the mechanism during the repair work.

How to use a gas cannon

If a person is superficially aware of how to turn on and off the specified mechanism, this does not mean at all that he is perfectly familiar with the use of heat guns. The principle of operation and the rules of operation can be studied in the instructions, if necessary, use the help of the wizard. When using a stationary gun, the following rules must be observed:

Eliminate the presence of flammable substances in the room in order to avoid their ignition.
Provide unhindered access to oxygen, due to which the gas cannon actively supports the combustion process.
It is forbidden to block the outlet and turn on the fan.
Since the air must circulate, and not accumulate in the heat gun, it is necessary to install the unit in an open area, to prevent clogging of the outlets.
Carry out the gas supply if the gas cannon is not broken and is working properly.
Turn on the ignition button until the piezoelectric element or piezo igniter is triggered.
To prevent fuel leakage, it will not interfere with the addition of a fuse in the circuit.
You should not save on fuel, otherwise the gas heat gun may fail very soon.

How to choose a gas heat gun

The most difficult thing is to make a choice, since the catalogs contain a huge number of positions of an interesting design with unique technical characteristics. To buy a gas cannon and not miscalculate, it is important to compare with electric and diesel designs. Someone prefers electric guns, where the main heating element is a heating element or a cylindrical spiral. However, it is important to understand the inefficiency of such a purchase for the future. Below are rated gas guns, which have been proven to be effective and economical to use.

Manufacturer

Ballu Industrial Group brand products are professional heat generators that do not need to be installed. All guns are mobile, and with the help of a special handle they are conveniently and quickly transported. Photos of such cylindrical models can be found on numerous sites on the network, however, before buying, measure the area of the heated room and not save on such an important purchase.

Reviews

Anna, 35 years old At first she heated the dacha with bottled gas, then she bought a potbelly stove with a ceramic plate. It was cold anyway. A friend advised the heat gun; she took Kraton for 4,000 rubles. It warms perfectly, there are no complaints, I no longer suffer from drafts in the country.

Marina, 39 years old We have a Heat stream 40-GFA-E gas cannon instead of main heating at home. For a room of 75 squares - ideal. Bought a few years ago, it cost 5,000 rubles. Saves electricity, distributes heat evenly. Everyone was satisfied.

Design features and principle of operation of a gas heat gun

The first thing you need to know when choosing the best representative of this type of unit is the internal structure of the heat gun and the features of its operation. Outwardly, the hero of our review is a cylinder located on a stand with wheels. The most important elements are hidden inside the body: a fuel supply system (regular or liquefied gas), a special fan, a thermostat and a gas burner. The rest of the free interior space is called the combustion chamber. Also a necessary component located directly on the body or on a transport stand.

NOTE! (click to find out)

Heating the room is achieved through the following sequential gun actions:

The electric motor drives a fan that blows cold air into the chamber.
The burner is supplied with gas, ignited by means of a piezo ignition.
The flame heats up the air inside the cannon.
The above-mentioned fan under pressure "shoots" a stream of heated air flow into the room.

Gas heat gun classification

Despite the apparent simplicity of the design, the technology we are considering has several subspecies that differ in heating technology. Let's take a closer look at each of them.

A heat gun with direct heating of air masses is an outdated but effective option

In this modification of the natural gas gas cannon, an open fire is used (as in the burner of a gas stove). Despite the good level of efficiency and rapid warming up, harmful components formed during the combustion process also enter the room. In connection with this fact, the use of such a device for heating living quarters is strictly not recommended - fresh oxygen in such conditions will be negligible.

Indirect heat gun - efficient error correction

Unlike its non-ecological and unsafe "competitor", such a model will simplify the life of the owner, preserving his health and indoor climate. This is done by adding a chimney to the design, through which all negative components are discharged outside the working area. But there is also a fly in the ointment - gas cannons of indirect heating have a high cost and a very limited presence in the domestic market, as well as increased dimensions that complicate transportation.

Purpose of gas heat guns - who is suitable for such a technique

Having dealt with some theoretical foundations, we propose to determine the scope of application of this equipment. You need to know this, since a natural gas or liquefied gas heat gun is not suitable for every homeowner or entrepreneur:

Heating of industrial premises- in this area, the heroes of our review have become very popular due to their excellent efficiency and wide service area.
Construction works and repairs- this area covers both commercial activities and the household needs of ordinary people.
Providing a microclimate in living rooms- used only in extreme cases when it is impossible to provide a comfortable temperature in other ways

How to correctly calculate the power of a heat gun before buying

Another important point in choosing a gas-fired heat gun is a preliminary calculation of the power for the heated room. For the correct calculation of the characteristic, the following formula is used:

Q = V × ΔT × k , where:

V- room volume, m³;

ΔT- the difference between the temperature outside and your desired value in the room, ° C;

k- the coefficient of thermal insulation of the building (from 0.6 to 4, depending on the construction of the walls).

How to connect a heat gun to heat a house, garage or other room

Inexperienced users very often have many questions related to the correct connection and startup of equipment. There is nothing reprehensible in this, since gas has an increased explosive hazard, and in combination with electricity it is a truly "explosive mixture". Anticipating such situations, our editorial office invites you to find out how to do such a procedure competently, efficiently and safely.

Description of actions	Illustration
We attach the reducer and the hose supplied with the device to the gas cylinder or main pipe. We connect the other end of the hose to the heat gun.
We find an available source of electricity and connect our unit to the network.
We turn on the device by pressing the buttons (may be called “Start”, “Start”, etc., depending on the model). We regulate the temperature on the remote panel, setting the required value.

How to choose the optimal gas heat gun: useful tips

You are just a few steps away from buying a gas cannon! But we recommend that you wait a little longer and listen to a few recommendations that simplify the selection and further operation:

Be sure to calculate the required heat output in advance. Otherwise, you will constantly overpay for extra kWh, which will not pay off in the long term.
Keep in mind that large and powerful models make a lot of noise during operation, and also require constant replacement of LPG cylinders. In this regard, the use of such units for domestic purposes or for heating living quarters is an unprofitable business.
Do not use cannons with direct air heating as an alternative to heating in your house, apartment or other dwelling. Firstly, this is a gross violation of fire regulations, the consequences of which can cause irreparable damage. Secondly, the combustion products will turn the room into a "hotbed" of carcinogens and poisons.

Do-it-yourself gas cannon for heating a garage, construction site and more - an option for real techies!

Unfortunately, we live in a difficult time, when in most Russian families every penny counts. But due to this, more and more bright minds appear among the people who invent truly amazing things from improvised objects. "Is there a DIY gas cannon?" - surprised readers of our article will ask. In response to the question posed, the editors Tehno.guru invites you to watch a video from one talented "Kulibin". We think it will be much clearer than a thousand words!

We collect all the pros and cons - how profitable is a gas cannon for heating rooms

Before we firmly say "Yes" to the purchase of a heat gun for a summer cottage, garage or construction site, let's dot the i's, having decided on the advantages and disadvantages of the technique we are considering.

Dignity	Flaws
Favorable energy resource - gas is much cheaper than various types of liquid fuel.	Dependence on electricity - the gun will not work without “stable 220 volts”.
A wide range of sizes - from compact mini-heat guns to huge industrial models.	Samples with direct air heating are harmful to the environment and human health.
High level of efficiency compared to diesel or electric versions.	Devices increase the risk of fire hazard, especially when used by sloppy owners.
Increased mobility when using a LPG cylinder.	Time-consuming procedure for connecting the hose to the main pipe (in private practice, it is almost never used).

The best gas heat guns for space heating in 2018 - prices and customer reviews

The time has come for the most interesting - we invite you to get acquainted with the rating of the best models, as of 2018, compiled by the editors of Tehno.guru especially for our readers.

Ballu BHG-20

And in the first place is the “younger brother” of the previous nominee, which, as in the case of the representative of Master, can be called a universal and maximally balanced proposal.

Editorial rating Tehno.guru: 9.9 / 10.

Products of this class are used as permanent or temporary sources of heating - it all depends on the state of the thermal insulation of the room. In practice, this is an ordinary fan heater, only with a high degree of efficiency and unique functionality. Natural gas heat guns are used for high-quality and economical heating of greenhouses, greenhouses where flowers and vegetables are grown: during operation, they do not emit combustion products, unlike diesel-fueled guns, and are also more economical than electric counterparts.

The principle of operation of this class of units does not differ from other heat guns: the combustion chamber housing is cooled by air forced by a fan. The warm air is then directed to heat the room. Gas heat guns differ structurally from their electrical counterparts only by the presence of a burner instead of a heating element (TEN). The gas is ignited automatically using a piezoelectric element.

This device can be used both for residential premises and for heating production facilities. For example, a gas-fired high-performance heat gun with a capacity 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 cannon has a power 10 times greater, then it is capable of high-quality heating of a building with an area of about 3.3 thousand square meters. m or greenhouse facilities - 740 m 2.

One propane gas cylinder is enough for about 60 hours of operation without stopping, while it should be borne in mind 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 work The product is connected to a LPG gas cylinder that can be easily replaced as it is used.

A compact heat gun, capable of operating on natural gas, consumes only no more than 1 l / h to heat a dwelling.

Product classification

Gas-fired heat guns are divided into two main classes:

products for direct heating of the air stream;
units of indirect heating.

In the first case, when a open fire, in which propane gas burns, the combustion products enter the heated room, but the efficiency reaches its maximum when using this design. The dimensions of such a device are quite compact, very low cost, but ventilation is necessary for a constant supply of fresh air. High fire hazard - no inspector will sign an act authorizing the use of this device for residential premises.

The second option is more preferable, because the combustion chamber in the unit closed type, all combustion products are removed through a special pipe connected to the chimney. It is better to install such products in the open air, and pump warm air through a special system with a large-diameter sleeve made of non-combustible material.

Modern gas-fired heat guns, which indirectly heat the air flow, run on propane, which burns out without residue, and the removal of combustion products is no longer needed. Only their dimensions are larger than direct heating devices, respectively, the price is higher.

Application Requirements

The operation of a gas-fired product, regardless of the design features, requires a constant flow of oxygen from the ambient air for stable combustion. When a user chooses a model, then these features must be taken into account.

The pricing policy depends on the size, power and brand: the more difficult the working conditions, the greater the volume of heated areas, the more expensive a gas-fired heat gun will cost.

The room where the unit is planned to be located must have excellent ventilation to ensure that there is a constant supply of fresh air from the outside. If there is no ventilation, then you need to choose a model with a thermostat, which automatically turns off or turns on the gun, maintaining a sufficient level of oxygen. Equipment thermostat allows you to increase the efficiency of the product: when the optimal 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.

Gas heat gun with thermostat

Unit selection

The entire range of gas products has a very high operating efficiency, the fact of environmental cleanliness is also important - the burnt gas does not pollute the atmosphere, there are no extraneous odors, which is very important for farmers engaged in flower cultivation and growing vegetables.

How to choose a gas-fired fan heater from a wide range of models presented? To successfully make a choice, you need to learn more about the blue fuel used, the specific features of heating units and their design.

It should be borne in mind that similar heaters successfully operate from highways or from connected to a gas heat gun balloon... The efficiency of such a device becomes almost 100%.
To purchase the right product with effective performance, you need to calculate in advance how much power you need from the unit. Are being made room measurements: you need to know its volume. You should also check the quality of thermal insulation, whether there will be leaks. The higher the performance of the heat gun, the faster it will heat the room to the required temperature.
Pay attention to gas consumption to know how long the gun will work without first shutting down.

All gas fan heaters have a similar working scheme, how it works, we have already discussed in detail a little earlier. It is necessary to note the fact that many do not need to be connected to the network, because piezoelectric element can ignite gas without electricity.

TPG-10 kW for 7 thousand rubles is considered by specialists to be the best option for those places where there is no electricity connection nearby:

runs on propane and butane;
productivity - 300 m 3 / h;
temperature up to + 90 C °;
gas consumption max - 0.76 kg / h;
weight - 5.5 kg.

This gas heat gun can be used from a gas main or with a connected cylinder, in places where there is a mains connection and without electricity. The 10 kW Sturm GH91101 product has similar advantages; at a flow rate of 0.75 kg / h, productivity is up to 330 m 3 / h, and the cost is only 5590 rubles.

Experts strongly advise users to repair gas heat guns only in special centers where there are masters for gas equipment, in order to avoid causing irreparable damage during self-service.

Best-selling models

There are many models of gas cannons on the modern Russian market: Master, Ballu and many others, but we will consider only the most demanded ones.

Compact cannon with a power of 10 kW, the speed of its operation is up to 300 cubic meters / h, and the consumption is more than modest - 0.75 kg / h. The connection is single-phase, the weight of the installation is only 4 kg, it uses liquefied propane, it costs from 4.7 thousand rubles.

This model has a capacity of 1450m 3 / h. Her power with small dimensions it is impressive - 5300 W, and gas consumption - 3780 g / h. Therefore, its price is much higher - 10 thousand rubles. It is used for heating large shopping centers, supermarkets and industrial premises: repair shops, factory and factory workshops.

Ballu BHG-20 S

This is a representative of the middle class in the price category, can work for propane and butane, heating speed - 500 cubic meters. m / h, gas consumption - 1.2 kg / h, power - 18 kW, weight - 4.9 kg, and the price is from 5 thousand rubles.

All of the above models use a piezoelectric element to ignite the gas and are included in the 10 most bought models. Master is a US brand, but the country of origin today is Italy, and Ballu is a domestic development. For clarity, I advise you to watch a video about the functionality of Ballu:

Connection and operation

Before turning on the device, you need to read the instructions, where all the nuances of connection and use are described very clearly. You need to pay special attention to situations where you can not turn on the device:

with an increased content of dust in the air mass of the room;
if there are vapors of explosive substances;
the outlet is blocked by something.

Operating rules and safety measures may vary from manufacturer to model - read the attached documentation before starting work.

Gas heat guns are very economical compact products characterized by a high volume heating rate and efficiency, therefore they are considered by gas equipment specialists to be an ideal option for heating various large areas. I would like to note that the technical characteristics of Russian heat guns are not inferior to foreign brands, and their design is almost identical, so there is no point in overpaying.

Classic heaters will not be able to provide warmth to the room in the way that a gas heat gun can. It very quickly raises the air temperature in almost any room - residential, utility, warehouse, etc. Manufacturers offer a variety of models to suit the tastes of all buyers.

You will be able to feel the positive effect of the equipment literally in a matter of minutes if you run the device at maximum power. Such a device is powered by gas, and the heated air is circulated by a heat fan. Due to its high efficiency, a gas cannon for space heating belongs to an economical way of increasing the temperature.

Acquaintance with modern heaters

The demand for high-quality heating systems increases significantly closer to the beginning of autumn. Not always timely switching on of centralized heating or some kind of breakdown with it can postpone the onset of the heating season. A heat gun for such a case will be very appropriate.

It is also able to act as an auxiliary equipment during construction or renovation. The hot air flow ensures rapid evaporation of moisture from almost any surface. The heated flow is obtained as a result of the combustion of gas coming from a cylinder or from a centralized network.

The equipment is capable of operating on both mainline and bottled fuel

The device is a relatively small cylindrical device with a streamlined, protected body. The front part is equipped with a protective mesh through which the heated air jet is directed. A gas heat gun also has the following components:

fixed power burner;
metal multi-hazard fan;
control unit;
metal heat exchanger;
ignition system;
protective thermostat;
additional devices used depending on the model.

What are the types of gas heat guns?

To make the right choice, choosing the optimal gas heater, you should familiarize yourself with the samples offered in online stores or building supermarkets. Products can meet the needs of both small premises and large buildings with a large internal cubic capacity.

With all the variety of manufacturers, the gas heat gun for residential premises is produced in two versions: direct and indirect heating.

Equipment belonging to each of these groups is available for use in domestic and industrial environments. The difference lies in appearance and function.

The direct-fired heater does not have high-quality filtration capable of cleaning the output stream from carbon deposits and soot. With them, oxygen is quickly burned out in small rooms. It is permissible to use such equipment only in those places where there is effective natural or high-quality artificial ventilation.

TPG direct heating

In addition to this disadvantage, there are positive qualities:

high efficiency, capable of exceeding 90%;
low electricity consumption;
reduced demand for fuel.

The indirectly heated gas cannon has an annular heat exchanger. It is the basic heating product in the design. The work of the installation is that everything happens according to the following algorithm:

liquefaction of gas;
liquefaction of toxic components;
emission of combustion products through the built-in chimney.

This type of equipment is the most environmentally friendly. In this regard, the use of indirect heating systems is more in demand. The downside, according to customer reviews, is the presence of a built-in chimney, which slightly complicates the movement of equipment and reduces mobility.

Performance characteristics

In order to achieve maximum results, it is worth knowing how to properly use a gas heat gun. The manufacturers have taken great care to simplify this process. The procedure is carried out according to the following scheme:

a burner is mounted inside the working zone, to which hydrocarbon gas fuel is supplied;
due to igniting devices, a flame is formed on the burner;
the fan blades pump the flow from the outside to the heated heat exchanger;
the blocking function, which helps the system not to overheat and not to fail, is provided by the thermostat;
bringing the surrounding atmosphere to the set temperature, which is measured by a built-in thermometer, the switch breaks the electrical circuit.

According to the output power parameters and the available area of the room, it is easy to calculate the desired value in watts guns. To heat 1 m 2 of an apartment with an average ceiling of 2.5 m, 0.1 kW of power is enough. Accordingly, a 3 kW device will be able to warm up a small room of 25-30 m 2.

Equipment device

The most popular for domestic conditions are mobile-type gas cannons. They are equipped with comfortable carrying handles and wheels. Stationary heating equipment is equipped with a large gas cylinder, which is problematic for fast movement. Its dimensions affect the duration of trouble-free operation. Such installations are considered obsolete.

Natural gas (methane) cannons provide the required indoor climate. They can also be used in garage conditions in order to create an optimal temperature balance. Often, it is their builders who use them to work with stretch ceilings.

The built-in fan speeds up the supply of air to the consumers. The existing thermostat limits the heating.

More noisy in operation is the heat gun on liquefied gas (propane). Sometimes you can hear its second name "thunder gun". It is used as an environmentally friendly equipment not only for heating, but also for scaring away wild animals or flocks of annoying birds.

For equipment with indirect heating, the acceptable noise level is 40 dB.

Modern heat guns are characterized by maximum efficiency - the efficiency of the device is more than 90%, which cannot be "boasted" by any other similar equipment. It is also important that the burnt gas is not emitted into the surrounding space, that is, there is no risk of poisoning, and if the unit is used for greenhouses, conservatories and other premises, the plants will not experience discomfort.

When choosing a model, one should take into account whether it works only from main gas or whether it is possible to connect cylinders. In this case, the efficiency of the device is 100% full.

In order for the TGP to cope with the tasks set, it is necessary to correctly determine its capacity in accordance with the area and purpose of the room. Further, the thermal insulation of the room matters - if there is heat loss, the power should be increased by 10-15%, depending on the percentage of heat leakage.

The higher the TPG power, the faster it heats up the room.

Be sure to check the fuel consumption in order to calculate the amount in advance for trouble-free operation. If a power outage is possible in the area, it is worth paying attention to models that do not require connection to the mains - here the piezoelectric elements function in an autonomous mode.

It is strictly forbidden to repair gas equipment with your own hands without special knowledge. For warranty and post-warranty service and repair, you should contact specialized organizations.
