A range of equipment for heating unheated rooms is a huge choice. But among the existing models, infrared heaters for dachas have become very popular among consumers. Due to its mobility, high efficiency and absolutely harmless radiation, this type of instruments becomes indispensable for country houses.
The principle of the infrared heater
The work of most popular heat appliances is based on convective heat transfer. But the principle of working infrared heaters for cottages can be compared with the action of sunlight piercing the air and while not heating it.
In contrast to sunlight, this type of rays does not have an ultraviolet spectrum providing sunburn. Infrared heaters have only thermal radiation, heating those objects to which the beams of the device are directed. And already from them thermal energy extends to the surrounding space.
The internal design of the heating device is not particularly complicated. In the metal case, covered with a stable powder paint is an aluminum reflector. It is fixed the main heating element - teng, which can be halogen, carbon, ceramic, tubular. To ensure uninterrupted operation and long life, each infrared heater is equipped with a temperature thermostat and a sensor that disconnects the device in case of overheating.
Rules for choosing an infrared heater
To date, infrared heaters have only the best reviews. They are considered the most effective, safe and durable options for infrared heating. But among the huge variety it is necessary to choose exactly the option that best suits these conditions.
Therefore, specialists have created special rules for choosing an infrared heater:
- First of all, the power required to heat the room is calculated. In this case, it is necessary to consider how the heater will be used - as an additional or main source of heating;
- what kind of energy source is expected to be used. Usually for a country house electricity is used, since infrared heaters working on gas are designed for large rooms;
- selection of the heating element;
- place of installation of devices.
Heating element selection
Manufacturers have not been used for a long time to heat the spiral, since they are highly inflammable.
Therefore, it was decided to replace it with safer heating elements:
- Quartz tube.
- Heat-emitting ceramic plate.
- Halogen lamp.
The heating element, made in the form of a quartz tube, is a closed cavity inside which a spiral of carbon or carbon is installed. Advantages of this element are fast heating and high efficiency. However, due to the short life of the heating element, this kind of heater is usually used as an additional source of heating.
The heat-emitting ceramic plate has a reliable protection, which allows it to not glow and be completely safe. Despite the fact that the cost of such a device is slightly higher than the previous type, yet the feedback on infrared heaters with a ceramic tan is usually positive. This is due both to their economy (power consumption from 50 to 2000 watts) and long life (more than 3 years).
The halogen tan is essentially a halogen lamp that operates in the infrared range. Inside it there is a filament made of tungsten or carbon fiber. When heated, infrared radiation is emitted, having golden light.
The choice of heaters depending on the installation site
Also, the parameters for choosing a heating device will depend on the method of installation. Infra-red heaters for a summer residence are ceiling, wall and floor. Therefore, when installing them, you must adhere to certain rules.
Ceiling infrared heaters for cottages are considered more convenient, since they do not take up unnecessary space and the range of exposure is very extensive. They can be mounted both in a suspended ceiling and fixed to the ceiling on special suspensions.
Wall infrared heaters for cottages must be installed at some distance from the floor, especially if the family has a small child. If you need to install such a model under the window, then you can choose a model with skirting.
As for the floor type, they are not characterized by high power and efficiency, since during the radiation rays meet many obstacles. If there is no possibility to install a ceiling or wall model, then it is better to give preference to heaters with a carbon or tubular tee.
When installing a ceiling or wall infrared heater for a dacha it is necessary to observe the necessary distance of exposure to the rays per person:
- heater with a power of about 700-800 - 0, 7 m;
- heater with a power of more than, kW - not less than 1 m.
Overview of infrared heaters for cottages
An important factor in the choice of equipment is also the manufacturer. A brief overview of the manufacturers of infrared heaters for cottages will help the consumer to quickly orient and understand which brand to give preference:
- UFO. They are used both in open areas, and are also suitable for enclosed spaces. Do not burn oxygen and eliminate excess moisture.
- Sunny. It is used for closed rooms. It is characterized by lightness, compactness and quiet operation.
- Peony. Ceiling model with ceramic tan. Thanks to the rounded housing, the heating of the room is carried out with maximum efficiency.
Adhering to the above rules for choosing an infrared heater, you can always find a successful model for a country house.
