Max. heating area

A very conditional parameter that slightly characterizes the purpose by the size of the room. And depending on the height of the ceilings, the layout of the room and the equipment, the actual values ​​​​may differ significantly. Nevertheless, this item represents the maximum recommended area that the heat gun can effectively heat.

When determining the maximum area, usually, a universal formula is used that is valid for all heaters: 1 m² of floor space in a room with a standard ceiling height of 2.5 m requires 100 W of thermal power. Therefore, if the ceiling height differs markedly from this value, the actual heating area should be recalculated; for more details on scaling, see “Maximum thermal output".

Power adjustment

The method of adjusting the heating power provided in the design of the heat gun.

- Stepped. Step adjustment assumes the presence of several fixed power values, between which switching is carried out during the tuning process. The accuracy of such a setting is worse than that of a stepless one (see below), even in cases where there are quite a lot of fixed values. At the same time, perfect accuracy is far from always required, and setting a specific value is easier than selecting the position of the regulator with stepless adjustment.

- Stepless. Stepless systems include adjustment systems that do not have fixed steps and allow you to set the power value in any range from minimum to maximum. Due to this, this setting is extremely accurate, although in some cases it is not as convenient as the stepped one described above.

Features

Temperature control. The ability to change the heating temperature provided by the industrial heater. This function allows you to optimally adjust the operation of the device to the necessary conditions and heating intensity.

Thermostat. A thermostat is a device for maintaining the air temperature at the same level. The principle of operation of this device is as follows: when the required air temperature is reached, it automatically turns off the heating, and when it gets cold, it turns it on again until the air warms up sufficiently. The temperature of the thermostat operation, usually, is set by the operator of the heater.

Piezo ignition. The presence of a piezoelectric ignition system in the design of the industrial heater. In such systems, the spark necessary to ignite the fuel is generated by the operation of a piezoelectric generator, and its operation is based on the use of a special material that, when bent, generates an electric current. It means that no external power is required for ignition — the necessary energy is generated by the operator himself when the button is pressed. In addition, piezoelectric systems are considered very convenient for several other technical reasons. They are found mainly in gas industrial heaters (see "Power supply") because, for diesel fuel, such ignition is poorly suited.

Complete fuel combustion. This feature is found in gas and diesel models (see "Power supply"). It means that the fuel in the combustion chamber of the heater burns out completely, without forming soot and other by-products and practically without creating unpleasant odours. In addition, it has a positive effect on efficiency. This feature is especially important for diesel units because diesel and many types of liquid fuels are "dirtier" than gas and more prone to soot. Smokeless combustion facilitates the use of heaters in rooms where there are people — however, note that it does not cancel the requirements for good ventilation, since combustion products still need to be removed from the air.

— Fan mode. The ability to operate the heater in the ventilation-only mode, when the device circulates air but does not warm it up. The purpose of this function is obvious: situations when the room is already warm enough, or heating is not required for other reasons.

— Fuel level indicator. The presence in the design of a diesel heater of a sensor that signals the amount of fuel in the tank. The design and operation of this sensor may vary from model to model: in some devices, it constantly displays the remaining fuel; in others, it plays the role of an alarm and turns on only when the fuel level drops below a certain value. However, this feature makes it easier to monitor the condition of the unit and prevents troubles associated with unexpected emptying of the tank.

— Air filter. The presence of an air purification filter in the design of a diesel heater. One of the “weaknesses" of such units is the nozzles that supply the fuel-air mixture to the combustion chamber; contaminants that enter these nozzles clog them and can even disable them. The air purification filter prevents such troubles: it traps dust, sand and other mechanical impurities, ensuring stable operation and durability of the injectors.
