What if it is necessary to carry out construction in the cold season or urgently need a garage. In order not to delay the repair, the walls should be dried in the near future. An effective solution to the problem can be the installation of an electric heat gun. With its help, you can quickly complete many tasks, save time and money.
Heat guns have various modifications. First you need to determine what tasks the device will perform, calculate the power depending on the area of \u200b\u200bthe object, and then go shopping.
In contact with
Device
What is a heat gun and how does it work? The principle of operation of this thermal equipment is similar to the operation of a hair dryer. On the one hand, there is blowing cold air into the heating element, on the other hand, this air comes out already warm.
The device consists of:
- body - usually metal;
- heating element;
In addition to the main elements, there are thermal sensors from overheating, power and air flow regulators. Models running on gas or diesel fuel are equipped with a special air filter. Electrical devices, unlike them, do not need this.
The device is called a heat gun because it has an elongated cylindrical shape and wheels. It is the fan that is a distinctive feature and the main advantage of the unit.
The principle of operation of a thermal electric gun.
In order not to get confused and not make a mistake in choosing equipment, you need to answer the following questions:
- Whether the device will work in a small residential area or an industrial facility.
- Whether the room is ventilated or not.
- How to choose the equipment of the necessary power so that the device can work without overheating.
- Which is better - or a heat gun.
There are industrial models designed for large premises - warehouses, hangars, greenhouses. The power of such devices will be too much for a garage or for a summer residence. They are expensive and consume a lot of electricity.
Small units that can be operated at home have higher environmental performance, especially if they are powered by electricity. Here you need to pay attention to what area the device is designed for and whether it will experience overload.
Convectors also quickly warm up the room and have almost the same principle of operation - with ventilation. What is the difference and what is better - it all depends on the characteristics of the room and the individual preferences of its owner.
Problem of choice
How to choose a heat gun. First, you need to pay attention to the materials from which the body and burner are made.
The highest efficiency of an electric gun with a ceramic heater. Such models are the most expensive, but durable and productive.
If there is a financial opportunity, then you need to buy ceramics in a metal case.
The second important indicator is the power of the heat gun. It is calculated based on the following values.
For each square meter of the room, 100 watts are consumed. Therefore, a small room of 20 - 30 meters will require a minimum power of 2 - 3 kW. At the same time, the height of the ceilings should not be higher than 4 m.
Advice! The power should be a little more than necessary, then the equipment will not wear out, and if necessary (in the cold winter), it will be possible to increase productivity.
The third indicator is how the thermal equipment will be installed. It is planned to permanently operate in the same room or the device will be mobile. This will determine which gun to choose - stationary or on wheels.
for garage
A garage is a room that is ventilated and there are no crowds of people in it. If the owner is a driver, then the gun can run on used car oil, which is quite effective in terms of economy.
For the garage you can purchase: electrical heating equipment low power - 3 kW. Suitable for household models.
The electric model is safe, but more expensive to use. The area of the garage is usually at least 30 square meters. m. This means that you will need at least 3-kilowatt equipment that operates on a 220V network.
For home and garden
To quickly supply heat to a house or cottage, a household mobile device on wheels will suffice.
An electric gun is perfect for giving. The use of electrical appliances implies the good condition of the wiring in the house. The more powerful the device, the more it loads the network. If the technical condition of the electrical network leaves much to be desired, then you must first start installing new wiring.
To heat a residential building, an electric heat gun is used additionally when the temperature outside drops sharply.
Why is it not advisable to constantly use the device:
- Dries the air, which is bad for the condition of the respiratory system.
- Houseplants do not like dry air - you will have to spray more often.
- Wooden products are prone to cracking - doors, windows, furniture, floors.
For a home, it is better to use central heating - gas or steam, and an electric fan heater can be used for additional heating.
For heating a residential building, an electric heat gun is used additionally.
For building purposes
Mobile models are required for construction. What is a construction heat gun - this is powerful equipment from 10 to 100 kW. In the shortest possible time it is able to dry the wall, ceiling, concrete. The advantage is that it can be directed to a specific area. If we take into account that the power of thermal installations is from 3 to 1000 kW, then 10 - 150 kW will be optimal for construction work, depending on the purpose.
Overview of popular models
Domestic and foreign firms produce thermal equipment of various quality. According to consumer reviews, the rating of heat guns is headed by Ballu for the optimal combination of price and quality. Power is calculated for household, construction, industrial facilities - from 2 to 110 kW. Price - from 1500 to 223000 rubles.
- Zilon made in Russia. Price - from 2000 to 16000 rubles. Depends on performance.
- Timberk Sweden. Price - from 1400 to 16000 rubles.
- Termica Russia. The price is from 4000 to 8000 rubles. household models.
- Master Italy. From 2600 to 4 million rubles. All modifications of electric heat guns are on sale - from household to industrial.
- Vectra England. The price is from 2500 to 6000 rubles. household models.
The review of heat guns can be diversified by the domestic models Luch, Zubr, Interskol.
The power range of heat guns is very large. Starting from household appliances - 1.5 kW, ending with industrial equipment - over 1000 kW.
There are one, two and three phase models. The dimensions of the devices also differ - the more powerful, the more. The volume of air that the fan drives through the gun is from 80 to 1800 cubic meters / hour.
Some models are specially designed for wet rooms, have appropriate protection.
Semi-industrial ceramic products
The semi-industrial ceramic heat gun is designed for heating spacious premises: auto repair shops, greenhouses, warehouses.
Important! Good air conditioning equipment is not cheap; expensive materials and sophisticated technologies are used for its manufacture. Devices for permanent use should not be chosen from a cheap segment.
Business facilities should save on territory maintenance, so they are most often multifunctional, mobile, combined in terms of fuel use. The most environmentally friendly are ceramic heating elements.
Advantages of ceramics:
- durability;
- no harmful compounds in the air;
- no smell;
- dries the air less
- higher efficiency at the lowest cost.
Such characteristics are more suitable for rooms in which people work or live. What is better - a convector or a heat gun, you can answer: choosing a cheap convector, you can make a mistake. Choosing a cheap heat gun - also.
Semi-industrial ceramic heat gun is designed for heating spacious rooms.
Testing of the device should be carried out without touching the metal case. If it doesn't spark, you can use it. For ease of movement, you can put the device on wheels or install it on a stretcher.
Useful video: how to make a heat gun with your own hands
You can buy a unit in a supermarket, picking it up for your needs, taking into account safety. But you can make a heat gun yourself - this will greatly reduce the cost of construction and allow you to use it in utility rooms.
In some cases, it is required to warm the air in the room without a stationary heating system. The only way out in this situation is a portable heater. In times of crisis and rising prices, heaters are extremely expensive. That is why many are wondering how to make a heat gun yourself. This is an ideal heating unit that compares favorably with other types of heating devices.
Advantages of a heat gun
Among the obvious advantages of a homemade electric heat gun is its mobility and the ability to deliver it to any place at no cost. It is convenient to use and easy to repair. A heat gun, built or assembled by hand, has improved performance.
A homemade heat gun is a special device whose main task is to heat large residential or warehouse premises. This heater runs on electricity, but alternative energy sources can also be used - kerosene, gasoline, diesel fuel, etc. Heat guns have different power levels. For domestic use, a unit with a power of 2 to 10 kW is sufficient. But simple models work at such power, which are not enough to heat a large working room or warehouse. If you need to heat a large room, then the power of the device must be at least 200 kW. You can order online and buy such a heater, but it is easier and cheaper to assemble it yourself.
Such a heating source has its advantages and disadvantages. First, you don't need a fuel tank. Secondly, electrical devices are safer than those powered by gasoline and kerosene. They are environmentally friendly and do not emit harmful substances. There is only one drawback - the electric gun is only suitable for rooms with a central electrical supply.
Yes, you can make any device, even one that runs on gas and diesel fuel, but it is very difficult to achieve the desired level of power if you additionally take into account safety regulations.
When assembling a gas gun, you run the risk of starting a fire or a powerful explosion, because to assemble such a device you need the skills of a gasman. The same applies to the diesel variant. Plus, you will have to take care of the constant addition of fuel, control of its level and compliance with safety regulations.
And the process of manufacturing a gun that heats the flow by burning gas will require at least quite serious skills in assembling such units.
Mains powered guns have no open flame, no combustible fuel, and the risk of fire is minimal. If there is a possibility of malfunctions, then all of them will be associated with the electrical part, so knowing everything about electrical engineering is a prerequisite for self-assembly.
Electric models are much easier to assemble, but this does not mean that you can do without specific skills and experience in assembling such structures. In addition to the fact that assembly requires the ability to handle many tools, you need to have sufficient experience or work under the guidance of a person with such skills.
If you do not have knowledge in the field of electrical engineering, then it is strictly forbidden to undertake the creation of such an apparatus on your own!
Principle of operation
Any, even a home-made electric gun, has the same principle of operation: air is driven by a powerful fan through a heating device - heating element, which warms up the air, which then exits into the heated zone.
To have an idea of the operation of this unit, you should carefully study its elements.
There are only five of them in the design:
- Frame;
- Ten for air heating;
- Powerful fan;
- Control device;
- Wire with plug.
The quality and speed of heating the room depends on the number and power of heating elements. The more heating elements, the more powerful and faster the air mass passing through the apparatus will warm up.
For some models, the rotation speed of the fans changes, and hence the amount of air blown through the device.
There is an erroneous opinion that the rate of heating the room depends on the rate of air passing through the heating elements. For our device, the power and the number of heating elements are important.
The air blowing speed determines only the level of uniformity of heating the room - the higher it is, the more uniform the heating. The heating element is responsible only for the amount of air heating.
How to assemble a heat gun with your own hands
Assembly assumes that the assembler has knowledge and skills in working with electrical equipment. If you are confident in your knowledge, you can start assembling.
Before the mechanical part, we deal with the electrical circuit. It is necessary to take into account all safety regulations and perform the correct installation.
A solid round pipe or box is suitable for the case. It must be metal. Metal is the most heat-resistant and wear-resistant material that can withstand temperature changes and external loads. We choose a case of large thickness with low thermal conductivity, since during operation the temperature of the device can be very high.
You can additionally cover the body with materials for thermal insulation. This will save you from burns if you suddenly touch a working device.
Then we install ten. The master himself determines the quantity and power, it all depends on your requirements for the heating device. If you mount several heating elements together, this will help to warm up the room faster and stronger, but will make the design of the device more complicated.
The temperature in the room depends on the power of the heater - the more powerful it is, the more heat will come out.
We fix the heating elements in the center of the case and attach the power wiring to them. Make sure that the contacts and connections are insulated.
Everything connects to the switch, or make a control panel. We take the wiring from the heaters and the fan and connect it, add switches and power wiring.
Before turning on for the first time, check all connections and circuits of the device for short circuits, all wires and contacts must be insulated, open contacts are prohibited.
If you have taken into account all safety requirements, you can carry out the first start-up of the heat gun.
It is very difficult to assemble a thermal electric gun with your own hands. This requires experience with electrical equipment, knowledge and skills.
Without knowledge, you will not assemble a heating device, but only triple the fire. We recommend that you simply purchase a factory model, and not risk your own safety.
It seems that building a heater on your own can save you a lot of money. But homemade machines can't be safe, especially if you're making them for 24/7 operation. The minimum that can occur is an overload of the mains and a short circuit. A homemade apparatus will quickly pump out oxygen from the room. For your own safety, we advise you to buy a heater in a company store.
In winter, a self-made electric heat gun will serve as a reliable and effective tool for maintaining the required temperature in almost any room, whether it is a large office or a confectionery shop. It is quite mobile, has a good percentage of efficiency and low energy consumption and power. You can accurately calculate how much energy is required to heat a particular room.
The beauty is that a hand-made heat gun can be used in various places where there is no heating system. It will be a great option for heating a room where construction or repair work is underway, in large offices (more than 300 sq. M.), in assembly shops, etc. Many users do not suspect that it is really possible to assemble a heat gun at home. This will require inexpensive materials, certain skills, desire and free time.
How does an electric heat gun work?
The heat gun (depending on the design features) can operate on fuels such as gas (propane, butane), electricity or hot water. Before you start assembling a heat gun with your own hands, you need to study and understand the mechanism of its operation. And the heat gun functions (it is made by hand or at the factory, it is not so important) according to this principle:
- (heater, gas pipe) is gaining the temperature set by the user.
- A built-in fan of sufficient power drives cool air through the case.
- The heating element gives the necessary temperature to the air, which is pushed out by the hot stream into the room.
As a rule, a do-it-yourself heat gun made with all the requirements in mind has sufficient reliability and safety. It is able to heat the air in the room to the required temperature in a short period of time.
Kinds
To understand which heating device you need and make a choice, we suggest that you familiarize yourself with the main types of devices in question:
- Electric heat gun. A do-it-yourself made device operates from a specific power source. As a rule, the device has a power of 3 to 35 kW. A great option for use at home or in the garage. It is environmentally friendly and does not emit any combustion products harmful to humans.
- Gas heat gun. With your own hands, you can make a device that will have a power of 15 to 150 kW. It connects to the gas system or cylinders. Among the shortcomings, one can note a large amount of energy consumed and the emission of combustion products, however, not dangerous to people.
- Diesel heat gun. It is more difficult to make it with your own hands than gas. This installation works on liquid fuel (diesel oil, kerosene). Has power from 10 to 140 kW. Used only in ventilated areas.
Device assembly features
First you need to draw up a plan for how an electric or gas heat gun will be assembled with your own hands. It should take into account the main characteristics of the device (for example, mobility, ergonomics, in other words, small size and weight). On the other hand, if you are going to make an electric gun at home, then such conditions are not necessary. You can choose your own parameters, the main thing is that they do not differ much from the basic standards.
It is important to know
A prerequisite for using a heat gun is the presence of a well-functioning ventilation system in the room.
This is due to the fact that during the operation of an electric heat gun, a heating element or a spiral will be heated, which not only heat the air in the room, but also dry it.
Main stages of work
When choosing materials for collecting an electric gun, you should take into account your technical skills, experience and financial capabilities. As practice shows, many craftsmen assemble an electric gun from what is at hand. There are options on how to assemble a device that is close to factory standards. Consider them:
The above option for assembling an electric heat gun will make it possible to manufacture a device of low power, but it will be enough to heat an apartment or office with an area of 50-60 square meters. m. With proper assembly and reliable materials, the output will be an excellent device for heating.
Building a more powerful heat gun
If the above option is not suitable for heating a room, then you can make a heat gun with your own hands more powerful. True, materials will have to be bought or ordered.
As for the assembly principle, it does not change much. You need to increase the walls of the case yourself, select a powerful electric motor, and install more efficient fuses. For a high power heat gun, a simple electric motor without an impeller is perfect. It is adjusted to the desired number of revolutions. You will also need a combination fan, but it will be harder to find on the market.
Before looking for assembly schemes and buying the necessary elements for a future heat gun, we advise you to really evaluate your own capabilities, experience and knowledge in this matter. Basically, all the diagrams and videos on assembling such a device are quite simple, but the risk of making a mistake is quite high.
This is very important to understand, since a mistake made can cause not only a failure in the power supply system, but also a fire.
Conclusion
If you have a great desire to assemble an electric heat gun with your own hands, and for this you have all the necessary materials and conditions, then why not satisfy your interest? We recommend that you first consult with people who already have experience in assembling such heating devices.
Do-it-yourself is quite simple and does not require special knowledge. This is also a plus. To get a more complete picture, you can refer to the videos, which explain in detail and show how an electric heat gun is assembled with your own hands. Always remember your own safety.
So, in general terms, we found out how an electric and gas heat gun is made with our own hands.
Heat guns have become one of the heat generators today, with which you can heat large rooms. But manufacturers did not limit themselves to powerful models, knowing that in the cold season in many regions the problem of heating various kinds of premises is relevant. For example, garage, warehouse and so on. Although most often this type of heating equipment is used to dry rooms that have been renovated. Therefore, it is worth understanding the guns thoroughly, and answering the question of how to choose it correctly for the necessary needs of the consumer.
It is impossible to say that there are better heat guns, and it is they who should be given their preference. To make a choice according to this principle means to make a big mistake. The whole point is not in the design of the device, not in its external presentable form, but in its technical and operational characteristics. Let's look at how to make the right choice using the example of an electric heat gun for an apartment.
Criterias of choice
So, there are three main parameters by which you need to choose electric heat guns.
- Unit power.
- The voltage from which it is powered (220 or 380 volts).
- The type of space being heated.
Heat gun power
There are certain formulas by which you can calculate how much heat energy is needed to heat a certain volume of a room. They are complex, because they take into account a fairly large list of various factors that affect the final result. Such factors include the thickness of the walls of the building, what material they were raised from, whether they are insulated, and with them the floor and ceiling, how many windows and doors are in the room, what material they are made of, which side of the world they look at, and so on. .
There is a simpler calculation option, which is based on the ratio of the heated area to the amount of required thermal energy. The ratio is as follows: 1 kW of thermal energy should be spent on ten squares of the area of \u200b\u200bthe room, taking into account the fact that the height of the ceilings in the room does not exceed 3 m. For example, if the room has dimensions of 3x3 m, then to heat it you will need:
3x3=9 m². This indicator is also multiplied by a factor of 1.2, since the power reserve, according to the recommendations of experts, should be 20%. That is, 9x1.2 = 10.8, which means that a heat generator with a capacity of 1.1 kW is required to heat this room. From the models of heat guns (electric) offered by the modern market, it is necessary to choose the one that will be larger in power and closer to the calculated indicator.
It should be noted that such an approach to choosing the power of a heat gun will be approximate. Therefore, let's consider a more precise approach. To do this, you will need to use this formula:
P=(V x dT x Kt)/860, where
- P is the power of the electric gun;
- V is the volume of the heated room;
- dT is the temperature difference inside the room and outside;
- Kt - thermal conductivity, or rather, the coefficient of this indicator;
- 860 is the number of thermal calories in one kilowatt.
A few words about the coefficient of thermal conductivity. It depends on the thickness of the walls of the building, on the material from which they were built. A few examples. Wall masonry in two bricks with well-conducted thermal insulation measures. In this case, the coefficient will be equal to 0.6-1. If laying in two bricks without thermal insulation is taken into account, then Kt is 1-2. If masonry is made in one brick with a heat-insulating layer, then the coefficient is 2-3. If an uninsulated garage assembled from corrugated board or sheet iron is heated with a thermal electric gun, then a coefficient of 3-4 will be used to calculate the power of the gun.
Based on the previous example, we will calculate the thermal unit. So, the room is 3x3 m with a ceiling height of 3 m. Its volume is 27 m², that is, we multiply the area by the height. We will assume that the temperature inside the room should be + 20C, and on the street -15C. The temperature difference is 35C. Let it be a well-insulated room, so Kt=1 (for ease of calculation). We substitute all the values in the formula, which will look like this:
27x35x1=945 kcal/hour.
To translate the result into kilowatts, you need to divide the resulting number by 860. In the end, it turns out - 1.1 kW. We also take into account the power reserve: 1.1x1.2 \u003d 1.32 kW. According to the catalog of electric heat guns, we select the first large option, the power of which will be enough to heat the calculated room.
It should be noted that experts divide heat guns by power into two categories. The first is up to 5 kW, which are called fans. The second - above this indicator, which are called guns.
Working voltage
There are two positions here:
- Guns with a power of up to 7 kW are connected to a network with a voltage of 220 volts.
- Thermal devices above this power are connected to a network with a voltage of 380 volts.
It is clear that for heating small domestic and office premises, electrical units operating from a 220-volt outlet are required. For heating large halls, construction sites or warehouses, a powerful device is needed.
But here the matter is quite different. Imagine an old house in which the electrical wiring was left over from Tsar Pea. And if, according to calculations, a heat gun with a power of 7 kW is required for heating, then the wires laid for sure will not withstand such a current. This means that they will begin to burn, and here it is not far from a fire.
Advice ! Before installing a thermal electric unit and connecting it to a 220 volt outlet, you need to check the wiring for resistance. And it is better to change it to a new one, taking into account the power consumption of the gun. After all, the likelihood that the insulation of wires has lost its characteristics over time is very high.
And one more thing that does not apply to voltage, but it must be taken into account when operating heat guns at 220 or 380 volts. This is their uninterrupted work. Usually, the following signs are indicated in the instructions for the device and on the packaging: 24/1 or 24/1. In the first case, the figures indicate that the thermal electric gun must be turned off for one hour within one day. In the second case - for two hours. By adhering to these requirements from the manufacturer, you can guarantee their long and uninterrupted operation.
There are two more criteria that you need to pay attention to. This is the noise that the gun produces during operation, and the temperature at which its quality of work will not decrease. As for the second position, all electric heat generators must work quietly at an ambient temperature of up to + 40C. Here is such a margin of safety.
Type of heated room
Let's face it, it's not the most important criterion, but it often depends on it whether you overpay for a heat gun or not. For this we need to give a few examples.
- For small office spaces such as a garage, dressing room, greenhouse, you should not purchase expensive models. Here you can get by with cheap, even Chinese farts.
- If the thermal unit will be used as a temporary heating device, then it is better to purchase a portable version.
- If it is installed as a permanent heat source, then it is better to buy a good branded unit, mount it in a certain place, as a stationary unit.
Additional selection criteria
So, we figured out the main parameters of electric heat guns, but there are other equally important positions that can seriously affect the choice. Here are a few of them.
- The heat gun must be equipped with a thermostat, with which it will be possible to regulate the temperature, and hence the power of the device.
- An important function of electric guns is the ability to turn off when overheated. Currently, almost all manufacturers provide their products with such a function, because these are serious fire safety requirements.
- It is better to choose heat guns with a metal case. It is stronger, withstands severe temperatures, and the metal itself becomes a source of heat release when heated.
- Devices with a cylindrical body warm up the room faster, because they are equipped with a heating coil, and not a heating element. For example, they can be used in the morning in the garage when you need to quickly warm up the car.
- Be sure to check if there is a service center in your area that can repair the model of the electric heat gun you are purchasing.
And one more point, which is determined by the misunderstanding of consumers regarding the type of thermal units. For example, such a category as infrared heat guns. What category do they belong to?
First, you need to start with the fact that infrared guns are completely different from electric models. They have a completely different way of releasing thermal energy. Therefore, they cannot be classified as electric, although they work partly from electricity, because the fan rotates due to electric current. But the main type of fuel for conversion into heat is diesel fuel, kerosene or gas. By the way, manufacturers warn that all these energy carriers should be only of high quality.
A do-it-yourself heat gun is made when it is necessary to heat a room that does not have central heating, and there is no opportunity to purchase an industrial heater. In addition, a home-made heat gun will be an excellent way out when the owner needs to maintain a certain temperature in non-residential premises, such as a workshop or hangar, in order to ensure the efficiency of production.
The principle of operation of a heat gun is that a heating element is used to heat the fuel element.
How to choose a heat gun? Depending on the method of heating the fuel element and air, the following types of heating devices are distinguished:
- gas;
- diesel;
- electrical;
- multi-fuel;
- water.
Each type has its pros and cons. For example, a gas heat gun is good because the energy carrier in it burns out completely. This saves money on heating. It is also good because it can be easily moved to another place of work.
Of the minuses, one can name the need to create a stationary gas installation if it is necessary to heat a large area. A gas heat gun, in addition, has a high degree of fire hazard, as it works with an open fire, so it cannot be used in buildings where flammable substances are stored and fire hazardous industries are located.
Another type of mobile heater is a water heat gun, which is good because it can heat a room for a long time when it is turned off. In addition, it is fireproof. However, it also has a minus - it is quite difficult to maintain, as it requires water as a coolant.
In order to finally decide on the issue of choosing a heat gun, you need to know what the heating scheme is in the required room. The owner of the premises can order such a scheme from specialists or draw it up himself, if he has the necessary knowledge. Therefore, if it is difficult to decide on the choice of a heat gun, it makes sense to turn to professionals.
In the process of choosing it, you should pay attention to the following points:
- price;
- power;
- ease of maintenance;
Usually, in all these parameters, the most advantageous is the electric gun. Such a device can operate from a conventional household electrical network, so it can be used in everyday life, for example, to heat a garage.
Self-made heater
Despite the fact that the industry can offer a wide range of mobile heaters of various models, an electric homemade heat gun is still popular among homeowners. The fact is that this device, assembled independently, will cost its owner several orders of magnitude cheaper than a similar device purchased in a store.
Repair of a self-assembled heat gun will cost a mere penny to its owner, since there will be no need to visit official service centers that work at fairly high prices.
A do-it-yourself heat gun is created from improvised materials, which allows you to have a wide range of spare parts in case of repair. It is not difficult to make such a heater design that takes into account all the features of the room.
If the owner decides to create a heater with his own hands, then the electric gun will be the best choice for him. The fact is that you can learn how to make a gun with your own hands in almost any electrician's reference book, and for work you will need to have some materials at hand.
Diagram of a heat gun
In this case, drawings of the device and its diagram will be required. Their use guarantees the quality of the assembly and the compliance of the device with fire safety regulations. Typically, the design of this heater includes:
- frame;
- heater for heating;
- powerful fan;
- control device;
- plug wire.
For the manufacture of the case during the installation process, you need a metal pipe or box. It is advisable to choose a case of large thickness with a low level of thermal conductivity, which will protect the device from mechanical influences.
Ten is usually taken as a standard sold in a store. At the same time, its power is calculated depending on the area of \u200b\u200bthe heated room and the load on the power grid. The electric gun, if necessary, can be equipped with several heating elements.
When mounting the fan in the case, you need to remember that it will be more convenient to install a device on the gun that regulates the speed of rotation of its blades, and it makes sense to put the control system for the fan and the entire heating device in a separate box.
In order to get additional savings, you can cover the body of the electric gun with heat-insulating paint. You can apply it to other elements of the device. This saves energy when heating the room.
What should you pay attention to when making?
When making an independent assembly of such a heating device as a heat gun, it is worth remembering a few points. The average power of such devices ranges from 1.5 kW to 45 kW. If you need more power, then it is recommended to design a diesel heat gun with your own hands.
During manufacture, all connections should be carefully checked for their isolation. You should not engage in self-assembly of an electric heater in the case when there is not even elementary knowledge in electrical engineering.
A do-it-yourself heat gun must be registered with the fire authorities. This will save the owner from a rather large fine for non-compliance with fire safety rules.
