If you need to quickly warm up an unheated garage or any other room, you can use the appropriate equipment. As great example acts as a heat electric gun (220V). You can find out how to choose such a device if you read the article. Such units are a lifesaver when construction or finishing work has been extended for an indefinite period, and the cold is already approaching.

If from time to time you are faced with the need to warm up a frozen car, then you can’t do without a heat gun, because quite often the car refuses to start in the cold. Considering that the range of such devices is truly huge, you must understand how to choose a gun. This task can be quite difficult. But if you follow certain rules and take into account important factors, then you can make a profitable purchase.

The gun can be used not only for the garage and construction needs, but also for, and also, if necessary, drying the room after finishing works. Experts advise deciding on the power of the device, design features and manufacturer.

How to make a choice based on technical characteristics?

The first thing you should pay attention to is what parameters will be optimal for the gun to operate. The selection must be based on suitable voltage and power. As for the last characteristic, when choosing it, you can use one of two calculation options. The simplest method that will allow you to determine what power to choose is as follows: for every 10 m 2 of room you will need 1 kW of power.

If you have to heat a room 4 x 6 m, then the most simple calculations will show that the power of the gun should be 3 kW. This value can be determined as follows: 4 multiplied by 6, which is equal to 24 m 2. Taking into account the recommendations, we can conclude that the power reserve is approximately 20%. The calculation will look like this: 2.4 multiplied by 1.2, which will give 2.88 kW. The closest value is 3 kW, and it is with this in mind that you need to select a device for heating a garage.

Alternative power calculation option

If you are faced with the question of how to choose a thermal electric gun(220V), then you can use another calculation option. The value will ultimately be more accurate. This approach is relevant when choosing a heat gun for your home. The formula takes into account not the area, but the volume of the room, as well as the thermal conductivity coefficient of the walls.

The formula is as follows: P=(V*dT*Kt)/860. Here, the volume of the room is denoted by the letter V and is defined as the area, which is multiplied by the height of the ceiling. The difference in temperature between indoors and outdoors is dT. Thermal conductivity coefficient - Kt. If the room has walls with good thermal insulation, then this value will vary from 0.6 to 1. When the equipment is selected for a room with average thermal insulation or brick walls in two rows, then the coefficient will be equal to the limit from 1 to 2.

You also have to select a heat gun for rooms whose walls are made of single-row brickwork. Thermal insulation in this case is usually poor, and the thermal conductivity coefficient will reach 3, while its minimum value is 2.

When choosing a heat gun for a dilapidated hangar made of corrugated sheets or boards, you should take into account a coefficient of 3 to 4. The number 860 is the number of kcal in one kilowatt. Before deciding how to choose an electric heat gun (220V), you must understand the essence of the calculation, which can be considered using a specific example.

If we are talking about choosing equipment for a garage and heating a car, then you can take into account the same volume of the room 4 x 6 m. And the ceiling height can be taken equal to 3 m. Inside the building the air temperature should be +15 °C, whereas outside -20 °C. The difference is 35 °C.

When the garage is well insulated, the coefficient will be equal to 1. Calculation formula in this case it looks like this: 72 x 35 x 1 = 2520 kcal/h. In order to convert this value into kilowatts, you should divide it by 860, which will give you 2.93 kW. It is important to take equipment with a power reserve; in the end, the required parameter will be equal to 3.5 kW, which is quite enough.

For reference

When deciding how to choose an electric heat gun (220V), you should pay attention to the fact that there is conditional classification equipment by power. Fan heaters are those units whose power reaches 5 kW; everything above is guns.

How to make a choice based on operating time and noise level: reviews

Experts also advise paying attention to the duration of the gun’s operation. When heating a room, such devices must operate without interruption for quite a long time. An electric heat gun (220V), reviews of which you can read below, can have a value that looks like this: 24/1 or 24/2. In these cases, the work duration is around the clock with a break of one or two hours.

In order to make the right choice based on characteristics, consumers are advised to also pay attention to the noise level during operation, as well as the range of operating temperatures. Having familiarized yourself with the range of modern devices, you can understand that they are capable of operating at temperatures ranging from +5 to +40 °C.

Selection by room type

One more is enough important criterion The choice of heat gun is the type of room. If you want to purchase a device for your home, it must work on the principle of indirect heating. But before buying a device for a greenhouse or heating a car, it is better to pay attention to simple options, which will eliminate the need to overpay.

When choosing a gun for temporary heating, you should take into account the fact that a portable case is better suited for these purposes. If the heater must be in one place for a long time, then you should choose a stationary device that allows you to fix it in a certain place in the room.

Select by additional parameters

An electric heat gun (220V) is also selected taking into account additional factors, for example, the presence of a temperature controller. Modern technology necessarily has such functionality, but if you want to save money, it is better to select a device with at least a step regulator. It will allow you to manage the efficiency and performance of the device.

It should also have an automatic shutdown function if overheating occurs. When the housing accidentally falls and the heating element overheats, a fire hazard situation arises in which the thermostat must operate. When choosing an electric heat gun (220V), you must also take into account the material at the base of the body. It is better to choose metal than composite or plastic.

The first option is more durable; in addition, in the event of an accidental power outage, the hot heating element will not be able to damage metal case. As for plastic, it can melt if overheated and cause a fire.

If one of your goals is to quickly warm up the room, then it is better to choose a cylindrical type device, because their heating element is a spiral. This option is great for heating a garage, which is especially important if you need to warm up your car in cold weather.

What else is important to consider?

When choosing an electric heat gun (220V) for the garage, you should also take into account the availability service center in your city, because if the equipment breaks down, repairs can be very expensive. But if the gun is selected for a dacha or private home, then it is better to purchase a design rectangular shape, which seems more rational, because there is a mesh heating element inside, which does not dry out the air as much and is not so dangerous in terms of spontaneous combustion. The most powerful air flow can be achieved if you use equipment with an all-stamped impeller. When choosing a heater for a construction site, for example, for installing a suspended ceiling, you should prefer a device with just such a fan.

Popular rating participant: “Interskol TPE-2 286.1.0.00”. Reviews

The popularity rating would not be complete without including one of the models from the Interskol company. This device is purchased somewhat less frequently than those described above, so it occupies only third place. When considering equipment for heating rooms, according to consumers, you should definitely pay attention to the electric gun, the brand of which is mentioned in the subtitle above. Its cost is 2119 rubles, and the equipment itself, according to users, can be used for rooms up to 20 m2.

The body has a cylindrical shape and is made of steel. Its surface has an anti-corrosion coating. made of fechral spirals. Air consumption reaches 240 m 3 per hour. The equipment weighs 4.5 kg. Its dimensions are 240x240x310 mm.

This electric heat gun (2 kW, 220V) has many positive features, namely:

• protective grille;
• stable support;
• bimetallic safety thermostat;
• ease of control.

During operation, the device can increase the room temperature by 25 °C.

Making a gun with your own hands

You can make a cannon from thin sheet metal, which will go to the body. During operation, you will need a heating element and an electric motor. To fix the spiral, make sure there is an insulating block. It is important to include switches, terminals and wires in the design.

Work methodology

Homemade electric heat guns (220V) do not have the same level of safety as factory models, so you must be nearby when operating them. The spiral is secured inside the housing using insulating blocks. Having prepared the bent metal halves, you can make a body from them, which is fixed into a single whole with self-tapping screws. At the end of the resulting pipe is installed axial fan. It and the heating element must be connected to the network via switches, after which we can assume that the electric gun is ready for operation.

Conclusion

Before you choose one or another model of electric heat gun, you need to evaluate all its characteristics. Among the durable ones, but the most important is the power, which is selected taking into account several factors. Before making a purchase, you should take into account the insulation of the room, as well as its area.

It will probably be no secret to anyone that heating a room is the most important task for its owner.

On modern market heating equipment Today there is a great variety of devices and appliances for heating rooms. Heat guns occupy a very significant and prominent place in this range.

Unlike other types of devices for heating and drying a room, heat guns perform this operation quite quickly and efficiently. It is also worth noting that this type of device appeared relatively recently, but has already gained popularity in various areas of its use.

Therefore, in this article we will describe in detail all the characteristics of heat guns, and also talk about the areas of their application.

What is

A heat gun is essentially a fan heater, which is designed to quickly heat rooms of various sizes.

This device got its name from the fact that it is presented in the form of a metal cylinder, which in appearance resembles an ordinary cannon.

But with all this, you should not associate these two heating devices.

This is due to the fact that a heat gun differs markedly from a fan heater in the following important points:

• has a significantly directed air flow;
• has a wide power range;
• quickly heats large rooms.

Device

As a rule, the structural elements of this device are:

• a heating element;
• powerful fan.

The heating element can be presented in the following types:

• a metal spiral made of refractory metals, for example, nichrome (the disadvantage of this type is that such elements intensively release oxygen in the room);
• heating element, which is made of sealed tubes filled with sand;
• a ceramic element, which is presented in the form of a plate with many small cells through which air passes (this type of heating element is the safest among all those presented).

It is also worth noting that the design of the heat gun is equipped with additional components, which include:

• thermostat that effectively protects the unit from overheating;
• thermostat, which is automatic mode will turn on the heat gun when the room temperature drops below the set one.

Principle of operation

The operation of a heat gun is very simple, so the principle of operation of the device is as follows:

Benefits of use

The design and operating principle of the heat gun rightly ensure its popularity in use.

As a unit for quickly heating a room, it has the following advantages:

• easy operation;
• does not require frequent maintenance;
• works silently;
• quickly heats a room of any size;
• environmental friendliness of use lies in the fact that the heat gun does not emit harmful substances in atmosphere.

One of the disadvantages of a heat gun is the cost of electricity consumption, which, in principle, can be offset by efficient heating of the room.

Kinds

The entire range of heat guns is usually divided into classes depending on what type of energy carriers are used to produce warm air flow.

Among them, the following important varieties can be distinguished.

. In addition to industrial purposes, they can also be effectively used for heating living spaces.

It is worth considering an important fact: depending on the power, electric heat guns can be connected to two-phase and three-phase systems electricity. Therefore, when choosing a device of this type, it is necessary to take into account the electrical wiring with which the room is equipped.

One of the most famous companies The manufacturer of heat guns is Ballu. Unit reviews:

. It is a very effective heating device, coefficient useful action which reaches almost 100%.

To obtain heat flow, natural gas is used, which completely burns out in a heat gun. It is recommended to use this type of units only in non-residential premises.

.

The name of this type of device indicates that diesel fuel is used to generate heat.

As a rule, a unit of this type is used for production purposes.

Water heat gun. Distinctive feature units of this type is that the heating element is made in the form of a heat exchanger through which hot water flows.

Infrared heat gun.

The design of this device does not include a fan.

Air heating occurs based on infrared radiation.

It is also worth knowing that a heat gun of this type can only heat a certain area of ​​the room.

Explosion-proof heat gun. This type of units, as a rule, is used to heat rooms with a high concentration of flammable mixtures, in other words, these can be transport hangars, as well as warehouses for fuels and lubricants.

Where is it used?

Heat guns are widely used in various economic sectors.

Heat guns can be used in the following industries:

In this article we tried to tell you as much as possible about heat guns and their applications. We hope that the information presented will be useful to you.

For a summer residence, in addition to heat guns, it is possible to use an infrared heater:

To ensure quality heating large premises, garage, basement, you will definitely need mobile heaters - electric heat guns. These powerful units can quickly dry, warm the air and maintain the effect for a long time; their service life is very long, and the cost is quite affordable. How to choose the right electric heat guns, we will consider further.

What is a heat gun

An electric heat gun is a mobile air heater that is used for domestic and industrial purposes to heat large premises: warehouses, garages, construction sites. The electric gun is mains powered, suitable for two-phase and three-phase circuits. This is the newest, environmental and safe look devices that do not emit toxins and exhaust gases, so you can use air guns to heat rooms in houses and spacious apartments.

Operating principle

The operating principle of a heat gun is simple: it is a ventilation device with additional heating. There are infrared thermal guns that operate on mains power using infrared rays and heat transfer. Electric heat guns are more suitable for quickly heating small areas. What do standard electric fan heaters consist of and how do they work:

• Heating element: heats up to high temperature, can be spiral or tubular (TEN). Lately TEN is increasingly being used because it burns little external oxygen and lasts longer than a classic coil.
• Fan: Creates a flow of air that is forced through the heater.
• Thermostat: regulates the temperature, prevents overheating - turns off the power supply when the air heats up to the desired level.

How to choose an electric heat gun

It is better to choose electric guns for heating rooms in specialized stores, where you can try the product, plug it into the network, and evaluate the dimensions. Online catalogs will help you make a preliminary choice: many sites have detailed video reviews describing all the details and characteristics, and the basic conditions are described.

How to choose the right heat gun:

• browse as many sites as possible: prices may vary significantly, pay attention to discounts, promotions, sales;
• When connecting the heat gun for the first time, there may be a slight odor - this is normal;
• do not buy high-power guns for your home - they will create too much air flow and noise;
• Quiet ceramic electric heat guns are well suited for cottages and apartments;
• pay attention to the power of the sockets and the type of plug;
• For your home, choose guns with high legs that do not lie flat to the floor.

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. Heat guns on natural gas They are used for high-quality and economical heating of greenhouses and greenhouses where flowers and vegetables are grown: during operation they do not emit combustion products, unlike guns running on diesel fuel, and are also more economical than their electric counterparts.

The operating principle of this class of units is no different from other heat guns: the combustion chamber housing is cooled by air pumped by a fan. The warm air is then directed to heat the room. Gas heat guns differ structurally from their electric counterparts only in the presence of a burner instead of a heating element (HEN). The gas ignites automatically using a piezoelectric element.

This device can be used both for residential premises and for heating production 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 square meters. 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 approximately 60 hours of operation without stopping, and it must 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 drops. For battery life connected to the product gas cylinder with liquefied natural gas, which can be easily replaced as used.

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

Product classification

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

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

In the first case, when heating the air flow is used open fire, in which propane gas burns, the combustion products enter the heated room, but the efficiency also reaches a maximum when using this design. The dimensions of such a device are quite compact, the cost is very low, but ventilation is required for a constant inflow fresh air. Great fire hazard - not a single 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 discharged through a special pipe connected to the chimney pipe. It is better to install such products on outdoors, and pump warm air through a special system with a large-diameter hose made of non-flammable material.

Modern gas heat guns, which carry out indirect heating of the air flow, operate on propane, which burns without residue, and the removal of combustion products is no longer necessary. Only their dimensions are larger than direct heating devices, and the price is correspondingly higher.

Application requirements

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

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

The room where the unit is planned to be located must have excellent ventilation so that there is a constant flow of fresh air from outside. If there is no ventilation, then you need to choose a model with a thermostat that automatically turns the gun off or on, maintaining a sufficient level of oxygen. Equipment thermostat allows you to increase the efficiency of the product: when you reach optimal temperature 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, during the construction of buildings and heating of agricultural facilities, where people are not constantly present.

Gas heat gun with thermostat

Unit selection

All the lineup gas products has a very high efficiency work, the fact is also important environmental cleanliness- burnt gas does not pollute the atmosphere, there are no foreign odors, which is very important for farmers involved in growing flowers and vegetables.

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

1. It should be taken into account that similar heaters operate successfully from highways or from connected to a gas heat gun balloon. The efficiency of such a device becomes almost 100%.
2. To purchase the right product with effective performance, you need to calculate in advance how much power the unit requires. Are being done room measurements: you need to know its volume. You should also check the quality of the thermal insulation to see if there are any leaks. The higher the performance of a heat gun, the faster it will heat the room to the desired temperature.
3. Please also pay attention to gas consumption, to know approximately how long the gun will work without the first shutdown.

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

TPG-10 kW for 7 thousand rubles is considered by specialists the best option For 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 network connection and without electricity. The Sturm GH91101 10 kW 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 5,590 rubles.

Experts strongly advise users to repair gas heat guns only in special centers where there are specialists in gas equipment, in order to avoid causing irreparable damage during independent maintenance.

Popular models

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

Compact gun with a power of 10 kW, its operating speed is up to 300 cubic meters/h, and its consumption is more than modest - 0.75 kg/h. The connection is single-phase, the installation weighs only 4 kg, it uses liquefied propane, and 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. Used for heating large shopping centers, supermarkets and industrial premises: repair shops, factories and 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/hour, gas consumption - 1.2 kg/h, power - 18 kW, weight - 4.9 kg, and price from 5 thousand rubles.

All of the above models use a piezoelectric element to ignite the gas and are among the 10 most purchased 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 functionality 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. Need to pay Special attention on situations when you can't turn on the device:

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

Operating rules and safety measures may vary among manufacturers of different models - study the attached documentation before starting work.

Gas heat guns are very economical compact products that differ high speed volume heating and efficiency, which is why they are considered specialists gas equipment ideal option for heating various large areas. I would like to note that Russian heat guns are not inferior in technical characteristics to foreign brands, and their design is almost identical, so there is no point in overpaying.

17.01.2017

The widest range of heating equipment present on the modern market allows you to choose the most efficient device that is fully suitable for specific operating conditions. We will not dwell on all these devices, but will only talk about electric heat guns. What are they and what design do they have? And is it possible to make such a heat gun at home? You will learn about this, as well as much more, after reading this article.

electric heat guns

We should start with what exactly is meant by heat guns today. First of all, they are heating devices, representing a group of heat fans. At the same time, they differ from the same fans in their high thermal performance and power. Consequently, here all units whose power is more than 2 kilowatts are classified as electric heat guns.

TOP-3. Rating of the most popular manufacturers

No. 1. Ballu electric heat gun

The world's largest company engaged in the production of climate control equipment. If we consider the assortment of this manufacturer, then special attention should be paid to the “Foreman” model, which has several modifications.

Among design features can be distinguished:

• double body, which is made of stainless steel;
• power, which ranges from 1.5-9 kilowatts;
• possibility of adjusting the angle of inclination of the device.

Note! The “Foreman” gun will cost from 2,700 to 6,000 rubles. A more specific figure depends on what kind of power we are talking about.

No. 2. "Tropic"

A worthy representative Russian manufacturers climate control equipment is the Tropic enterprise, specializing in the production budget options heat guns. Some of the best devices from this manufacturer are models from the TK line.

Of course, the main advantage of all Tropica products is their cost. At the same time, the company properly monitors the quality of the product, as well as ensuring that its technical characteristics fully comply with international standards.

No. 3. Frico

This Scandinavian manufacturer offers high-quality electric heat guns, but in Russia its products are known mainly for small-sized fan heaters from the Tiger series. But in order to efficiently and quickly heat large premises, it is advisable to give preference to the company’s new product – the stationary heat gun SWH02 Fan Heater.

This model is distinguished, first of all, by its ease of installation and operation, as well as automatic adaptation to the microclimate of the room in accordance with the established operating mode.

Note! The approximate cost of the SWH02 Fan Heater unit is from 43,000 rubles.

Design and principle of an electric heat gun

So, what is the device described in the article? To find out, you must understand one thing important point: a heat gun is unusual device, capable of warming up almost any room in a short period of time. In other words, this is a device designed for quick heating and effective drying during various types of technological operations.

You will probably ask yourself another question - why is this device even called a heat gun? The thing is that outwardly this unique heating unit is very similar to the design of a traditional army cannon, but at the same time it can heat rooms with high quality.

For the most part, heat guns include the following structural elements:

• actually, the heating element;
• air filter (present on some models);
• high power fan;
• thermostat (it is necessary so that the device can function in autonomous mode, that is, it is preset temperature regime in the room from which the gun operates);
• metal body, characterized by increased strength characteristics;
• thermostat (necessary to prevent overheating of the device).

What is the principle of action itself? And it consists of a series of actions that are performed in a certain sequence.

1. Stage one. The heating element produces thermal energy.
2. Stage two. Through a special hole located on the body, cold air enters the device.
3. Stage three. The air is warming up. Powerful fan pumps up hot air, moving it to the required location in the room.

What types of heat guns can be used?

You need to know this to understand the differences electric models from others. The classification in this case is based on the method of converting various types of energy carriers into thermal energy. Simply put, all heat guns are classified depending on what kind of energy carrier is used to produce heated air.

Note! If we talk specifically about electric heat guns, they, in turn, are also divided into several types, so we will briefly consider them.

Types and characteristics of electrical appliances

According to the characteristics of their operation, electric heat guns are divided into two categories.

Pros of using electric heat guns

The advantages of the equipment described in the article include:

• light weight;
• affordable cost (the 220-volt device is the cheapest of all those presented above);
• ease of use (the device is activated by pressing just one button).

Minuses

However, there are disadvantages - for example, the described heat guns:

• directly depend on electrical network(it is worth noting that, if possible, the devices can be connected to diesel generators);
• consume electricity, which is expensive.

Criteria for choosing electric heat guns

People choose electric heat guns for certain purposes, so they must pay attention to the criteria below.

Equipment power calculation

The simplest way to calculate the power of a heat gun is as follows: to heat 10 square meters of space you need a power of 1 to 1.3 kilowatts. For example, if the area of ​​the room to be heated is 80 square meters, then a gun of approximately 80-100 kilowatts should be selected for it.

Note! Also, the special table that we have given below should help you with your calculations.

Is it possible to make an electric heat gun with your own hands?

To create such homemade units Various elements and devices can be used, sold in all construction stores in the country. So, you can use a pipe for the body (it is important that the material is not a conductor electric current), for example, asbestos. Or, as an option, you can even build a plywood box. Go ahead. A nichrome spiral can serve as a heating element (such is used in irons and other household appliances). To increase the heating capacity of the spiral, it can be folded in half.

Important information! This spiral must be connected to a thermostat - it will regulate the degree of heat.

In this case, the spiral should be located inside the box or pipe (approximately in the center of the structure), and the thermostat itself should be located outside. At the end of the housing there should be a fan heater, perhaps not very powerful. In principle, this is approximately how a low-power electric heat gun works.

Note! The coil and fan must be connected to the mains alternating current, and necessarily separately.

Step-by-step manufacturing instructions

As an example, let's take a look at one of the simplest designs. First you need to prepare:

1. duct type fan;
2. regulator (it must regulate the rotation of the fan rotor);
3. heating element (we recommend using RVES, whose power is 2.2 kilowatts);
4. thermostat;
5. plywood (its thickness should be 1.6 centimeters);
6. various types of fasteners.

So, when everything you need is already at hand, you can proceed directly to production. The procedure itself consists of several stages; we will consider the features of each of them in more detail.

Step one. First prepare the base of the unit. It is on this basis that all structural elements will be located. For this purpose, take a sheet of plywood, then cut out a rectangle with dimensions of 67x47 centimeters. Finally, carefully sand the cut piece.

Step two. Due to the fact that the heating element you are using, as well as the duct-type fan, is already a ready-made device in itself, simply connect them to each other using a mounting clamp. Place the resulting double device on the previously prepared plywood stand. For this, use a plastic clamp designed for sewer pipes and a bracket. Attach the latter to the plywood sheet using self-tapping screws, and to it, accordingly, using self-tapping screws, attach the outlet pipe of the heating element itself.

Note! The back of the fan will rest on the stand.

Step three. Having installed and attached all the elements of the heat gun, you can begin assembling the electrical part of the unit. Take a heater with a fan and connect them (but, as mentioned earlier, only separately from each other). Therefore, for this reason, a thermostat must be connected to the PVES. In addition, you can also install a temperature sensor, which is necessary to control the temperature.

Step four. Connect a rotation regulator to the fan, thanks to which the intensity of air movement on the heating element will change, which, in turn, will help regulate the heat in the room.

Step five. To move the heater as conveniently as possible, you can attach four wheels to the bottom of the plywood sheet. That's it, the manufacturing process can be considered complete!

So, now you know everything about electric heat guns, you have read technical characteristics, prices and popular models. That's all, good luck and warm winters!
