Heat guns are specialized equipment that is actively used at construction sites, in large sales areas, at production sites, in garages and other premises. The cannons work according to the following principle: due to the heating of a special element built into the equipment, the air flow passing through it heats up. As a result, the latter heats the room that needs it.
Heat guns are classified according to type, purpose of use, and other factors. Therefore, to select the most suitable product, you will have to study not only the characteristic features, but also the best models.
To do this, we have compiled for you a rating of machines that produce heat, in which we will consider the most popular models from well-known and reputable manufacturers.
The heat gun rating was compiled on the basis of user reviews and the opinion of independent experts, so it can be considered impartial, well, and a little subjective.
Types of electric heat guns
All heat guns are divided into two main groups, depending on the power source. Accordingly, they are electric and diesel. We will start, perhaps, with the first.
Electric cannons
So, electrical models are classified, first of all, by their rated voltage, which can be 220 V and 380 V. For 220 V power supply, both household and industrial units can be manufactured. But especially powerful and productive models, not intended for use in everyday life, need a voltage equal to 380 V.
The second criterion according to which the heat guns are divided is the power of the heater. Household models, as a rule, are equipped with a motor with a power of 1.5 kW to 3 kW, and industrial ones - from 3 kW and above.
In addition to the voltage and power rating, the electric heat gun is classified according to a number of criteria:
- type of heating element;
- productivity;
- the shape of the case;
- availability of additional functions.
The cannons are also divided according to the type of installation: they can be floor-mounted or universal. The latter have special mounts for placement, including on the wall.
Diesel cannons
The name of this type of gun speaks of the used energy source - diesel fuel. Diesel fuel burning inside the cannon heats the air, and the operating fan pushes it into the room. Diesel cannons are divided into direct and indirect heaters.
The principle of operation of such heaters is as simple as possible: a burner works inside the cannon body and burns fuel. A fan in front of it pumps air through the burner, pushing it out of the nozzle. In direct heating structures, combustion products are released into the room together with hot air. Therefore, such models are not recommended for use in rooms where people or animals are present. A direct heated cannon is ideal when constant heating or quickly raise the air temperature in a large non-residential area with good ventilation (warehouse, hangar, garage).
Diesel heat guns of indirect heating are distinguished by separate removal of heated air and combustion products. A characteristic feature of such a heater is a small exhaust pipe located at the top of the housing.
The outlet of such a gun is connected to a pipe that removes the combustion products outside the heated room.
In models of indirect heating, the fuel is burned in a special container from which the pipe is drawn. The air is heated not from the burner itself, but from the walls of the combustion chamber.
Attention! Any heat guns, regardless of type, use air from the heated room to heat up, therefore they dry it out a lot. It is desirable to use heaters of this type in conjunction with ventilation. In the case of direct heating guns, ventilation becomes not only desirable, but mandatory.
What to look for when choosing
- There are 5 main points to be aware of when choosing such heaters. This is:
- power;
- the shape of the device;
- heating element material;
- functionality;
- manufacturer.
The heat generated by the cannons is expensive, therefore, the main criterion when choosing a model is its power.
Power
The choice of the power of the electric gun directly depends on the "throughput" capacity of the electrical network of the premises. Knowing the nameplate data of the heater indicated by the manufacturer, you can easily calculate the current strength allowed for a specific network. The power of any electrical device is determined by the formula:
- P = I x U, where:
- Р - device power, (watt) W;
- I - current strength, (ampere) A;
- U - mains voltage, (volts) V.
Substituting the values from the device passport into the formula, the current strength is determined. Take, for example, a 5 kW cannon. We get:
5000 W: 220 V = 22.7A. Let's round the value up: 23A.
A 5 kW heat gun will consume a current of 23A from the network. For comparison: most modern city apartments are equipped with electrical circuit breakers rated for a current of 16A. Conclusion: a 5 kW cannon is not suitable for an ordinary city apartment.
Device shape
This parameter is key when there are certain restrictions on the location of the heater. Gas or diesel cannons are equipped with fuel tanks and are therefore bulky, bulky devices. To ensure the normal operation of such models, it is necessary to have sufficient space in order to freely service them. If we are talking about electrical machines, then their capabilities are determined by the proximity of network outlets or the availability of free space for laying power cables.
Heating element material
This criterion only applies to electric guns. In their production, 3 types of heating elements are used:
- Heating element;
- open spiral;
- ceramic plates.
The heating element is a tubular electric heater, which is the most common type of heating element used for an electric heat gun. I.e,
Heating element is the best option according to the "price-quality" scheme
An open coil is the cheapest type of heating element. In fact, this is the same heating element, only without the tubular body. In modern models, it is rarely used due to the high degree of fire hazard. Other disadvantages are its fragility and the ability to strongly dry the air, as well as the possible unpleasant odor that appears due to the combustion of dust particles falling on it.
Ceramic heating plates are a more modern type of heating elements, devoid of the disadvantages inherent in spiral heaters. They practically do not dry the air, they are characterized by efficiency and lightness. Its only drawback is its high cost.
Functionality
This is a key indicator for heaters of any type. Without exception, all heat guns use an electric fan. It pumps air through a burner or heating element, pushing it out. This determines such a parameter as the fan performance. Most models of guns of various types have a capacity of 300 m³ / hour. Sometimes in technical literature, this parameter is called air exchange.
The functionality of a device is largely determined by performance and power. Knowing the room to be heated, you can apply the ratio: 2.5 m³ volume = 100 watts of heater power. Fast air exchange is used when it is necessary to warm up a large volume of a room in a short time.
Functionality helps to properly allocate resources: why use a high-power device in a small room if there is no need to warm it up quickly?
Consider, for example, heating a garage with dimensions of 6m x 4m x 3m:
- Let's calculate the volume of the room: 6 x 4 x 3 = 72 m³.
- We divide the result obtained by the calculated unit of volume: 72: 2.5 = 28.8.
- Let's round up the value: 28.8 ~ 30.
- Let's multiply the resulting value by the unit of power in the calculations: 30 x 100 = 3000.
As a result, we find that a 3 kW heater is needed to heat a garage with a volume of 72 m³. We add that the obtained value provides an air temperature of 15˚С.
Manufacturer
When choosing a gun, attention is paid to the manufacturing company, most often, under the influence of the advertising campaign carried out by it. It is necessary to take into account the fact that a modern heat gun is a complex combined device. For its normal operation, service maintenance is required, especially for diesel and gas versions. The requirements of Gostekhnadzor for gas guns are the same as for gas stoves, furnaces and boilers. Therefore, when choosing a manufacturer, it is necessary to pay attention to the presence of service repair centers of the company near the place of operation of the heater.
Other criteria
In addition to the indicated basic parameters necessary for choosing a heater, there are several additional ones, the presence of which can determine the choice when everything else is equal. Many gun models are equipped with an emergency shutdown system. Considering that the process of heating a room takes a lot of time and it is not always possible to control the operation of the gun by a person, the presence of such a system is often a decisive factor. There is another option worthy of note:
- Roll-over control system. It is installed on cannons with fuel tanks.
- Room heating sensor (thermostat). It is able to turn off the device when the set air temperature is reached.
- Temperature control of the gun body. This function will turn off the gun in case of emergency heating of the case.
- Fuel level sensor. This element signals a decrease in the fuel level in the tank to a minimum value.
Above were the basic and widespread additional functions. In addition to them, each company sometimes supplies its equipment with other systems that are more necessary in its opinion.
Which heat gun is better to buy
The type of gun required is determined by a number of parameters:
- The presence of people in the room. For example, guns that run on any liquid fuel are not suitable for use in crowded places due to their harmfulness and noise.
- The frequency of use of the equipment and the heated room itself. Let's say you can put a small diesel cannon in a garage that does not require a high temperature. In this case, a large and powerful unit is simply not needed.
- Room configuration. If there are several isolated rooms in the same building, it is better to buy 2 or 3 small cannons than one large one.
- The presence of powerful electrical wiring. The electric heat gun consumes current intensively, so a weak network may not withstand the generated voltage.
With the general equality of the parameters, the best will be the gun, which has greater autonomy and protection from various kinds of emergency.
Which view is better: gas cannon, diesel or electric
All heat guns are designed for one type of work - space heating. Therefore, in order to understand which heater is better in each specific situation, you need to take into account all the necessary factors. Diesel cannons are not suitable for premises where people are constantly present. In the opinion of the author of the article, there are the following reasons for this:
- Diesel cannons are the noisiest of all types.
- They are bulky and take up a lot of space.
- Even for indirect heating cannons, the smell of combustible fuel spreads throughout the premises.
- In crowded places, it becomes possible to access the heater for children.
Diesel cannons are also unsuitable for well-traversed areas and due to the odor generated when refueling.
The best option for living spaces is an electric cannon. If the consumer is poorly versed in electricity, then to choose such a heater, you need to remember one number - 3 kW. Models of such power will withstand any electrical wiring, however, do not forget that during it work, it is undesirable to include additional high-power electrical appliances (stove, iron, kettle, boiler). With a very weak electrical network, you can choose a gas cannon, but then it is imperative to provide forced ventilation of the air in the room.
To assist in the selection of a heater, a heat gun rating has been compiled based on a comparison of key parameters.
