Criteria for choosing a heat gun for a summer residence
When you need to quickly heat a cold room that has not been heated for a long time, or maintain normal thermal conditions in a large enclosed space, dry moist air so that mold does not start in the room, a heat gun will be an ideal option for solving all these problems. And if the owner has already realized the need to buy something so useful to him, the next question that confronts him is how to choose a heat gun. The market offers a wide variety of options, each of which will be good for achieving a specific goal.
Description and use of units
Heat guns create a stream of hot air, dispersed throughout the room with a fan built into its body. This method of heating compares favorably with others. Here are some advantages of heat guns:
- Ecological safety - the electric motor does not produce hazardous waste that appears during the combustion of combustible substances. The oxygen content in the heated air practically does not decrease. Since there is no open flame, the device is considered fireproof.
- Ease of use - the heat gun does not need to install complex electrical equipment and other conditions, for example, hoods. You just need to plug it into the electrical network using a regular outlet with the required voltage.
- Small size - despite the shape of the hull, the gun is quite compact when compared with other heating appliances that run on gas or diesel fuel. It easily fits in the trunk of a car, and it can be freely transported, for example, to the country.
- Lack of noise - during the work the heat gun does not make loud sharp sounds. Their level, as a rule, does not exceed 35055 dB. The upper figure of this range is considered the normal noise level for office work.
Heat guns are very practical due to their size and weight.
Selection of models by power
The main thing in choosing an electrothermal gun is the correct choice of heating power. It is she who affects the amount of air that will be warmed during the period of work. For example, for a product with a power of 2 kW, the air consumption is 120 cubic meters. m / h, and for a selected 3 kW gun, the thermal flow reaches 300 cubic meters. m/h So, such a product will provide heat to the house. A simplified selection scheme may be as follows: a power of 1 kW is enough to heat 10 square meters. m (if the height of the room does not exceed 3 m).
Professionals perform a more thorough calculation using a special formula.
When calculating, it is not the dimensions of the room that are taken into account, but its volume and the thermal conductivity of the walls.
Calculation example
The dimensions of the heated object are 10 square meters. m, and the level of its upper border is 3 m. Therefore, the volume of the object will be 30 cubic meters. m. Suppose that the device must heat the air in the room to at least + 15 ° C, while outside - frost -20 ° C. Therefore, the difference between these values reaches 35°C. Let's say that the walls of the structure perfectly retain heat, and the thermal conductivity multiplier will be 1 unit.
In this video you will learn the pros and cons of a heat gun:
The calculation of the required power is carried out as follows: 30 times 35 times 1, then divide by 860. The total is 1.22 kW. This means that for a room with an area of 10 square meters. m, a heat gun with a power of 1.22 kW will be optimal for the best heating in the winter. But at the same time, it is better to purchase a model with some reserve, for example, with a power of 1.5 kW.
If you systematize the heating equipment by power, then products up to 5 kW are considered as household ones. Such heat guns operate from an electrical network with a voltage of 220 V. They are very easy to use in summer cottages, car garages, offices, private cottages. Sometimes such units are called fan heaters.
It is important to understand that not every heat gun comes with a power cord and power plug. Please note that they will need to be purchased separately.
Main design features
If a heat gun is required for heating, the choice must begin with taking into account the configuration of the unit body. In the heating equipment market, manufacturers exhibit models of two forms:
- rectangular;
- tubular.
They have their own characteristics and positive aspects.
The tubular variety has an elongated steel body that looks like a cylinder. A heating element is fixed in the depth of the case, which provides almost instantaneous access to the nominal temperature. A tubular outdoor unit allows you to produce a directed flow of hot air.
The object warms up extremely quickly, a heat gun of this type is suitable for drying rooms. However, dust and dirt, when sticking to the coil, can become a prerequisite for the appearance of foreign odors and excessive oxygen consumption. Therefore, for residential facilities, this kind of device will be irrelevant.
Each type of heat gun has its own characteristics. A rectangular device contains a heating element as a heating source, and it, in turn, is much safer than a heating coil. Heating is not as fast as it happens in the tubular model, but at the same time it is more convenient and pleasant than from modifications with a tubular body. The device can be used in residential and office premises. The block is not so large and does not require much space.
It is worth paying attention to the structural components of the thermal gun. If it is bought for fixed use, it is worth making sure that it has a stable stand - legs or foot.
In some cases, the device must be moved frequently. The steel case heats up during use, and in order not to burn yourself and not damage others, you will need to hold the unit by the handle.
Heating level adjustment
In addition to the heating power, many models provide power control. The step switch can turn on full power to quickly warm up the room, or partial power for constant heat support, and also be used as a secondary source of heating. Some models are equipped with a fan that works without heating, only for air circulation.
For an electric heat gun, insurance against overheating is important. Reaching a critical temperature threshold during operation, the gun turns off. This can happen if the body of the device is accidentally covered with something - the protective system is triggered and the heating stops.
