Electric convectors are a special system designed for space heating. The principle of operation of the devices lies in the uniform distribution of heated air flows over the entire area. The construction consists of a heating element, which is enclosed in a housing equipped with slit-like holes. Such design features allow air currents to move freely inside. Natural convection heats the air streams, but does not dry it out.
Electric heaters and their advantages
Electric floor radiators are in great demand among the population. They are used to heat houses, apartments, summer cottages and work offices. This is due to a rather extensive list of advantageous features.
- You can start using it immediately after purchase.
- Reasonable cost in comparison with expensive radiators and boilers. The price of convectors ranges from $ 100 - $ 150.
- The maximum permissible efficiency, which reaches 95%.
- There is no need to spend additional money during operation on maintenance of the heating system. Also, there are no difficulties during installation.
- Precise maintenance of the set temperature in the room.
- Does not burn oxygen.
- The convector has no moving parts that can cause noise. The design works completely silently.
The service life declared by the manufacturers, as a rule, corresponds to reality. The average service life is 20-25 years.
The main disadvantage is an increase in the cost of paying for electricity. Electricity consumption depends on the possible places of heat loss from the room: the quality of insulation, the area of windows and doors, the type of installed double-glazed windows.
Types and types of radiators
The range of electric convectors and their functionality is characterized by a great variety. This group includes all modifications equipped with fins, since it is such a case that allows the most efficient heat dissipation.
All electric radiators are divided into two large groups: non-liquid and liquid.
Depending on the place of installation, electric radiators are divided into the following types:
- floor;
- ceiling;
- wall.
There are other types of structures: ceramic, glass, floor and baseboards.
By design features, electric heating batteries are classified into the following types:
- infrared heaters;
- fan heaters;
- oil.
According to the method of execution, structures are divided into portable and stationary.
Electric convectors with liquid heat carrier
The main characteristic feature of this type is simplicity of execution, the composition includes a small number of parts. The convector is heated thanks to a tubular electric heater of average power, which ranges from 300-500 W.
There are also more powerful modifications. Heating elements are placed in oil, water or non-freezing liquid.
Quiet operation.For safety reasons, it is important to ensure that the hot surface does not come into contact with flammable surfaces.
Non-liquid electric batteries
Liquid-free and dry electric batteries, in comparison with liquid counterparts, are lightweight and also heat up faster.
In these modifications, there is no intermediate heat carrier, therefore, heat transfer occurs from the heating element to the heat transfer surface directly. The work is based on the principle of convection.
Floor electric radiators
They are located in the floor. They belong to a large group of hidden heating systems. Their advantage is high efficiency and preservation of usable area.
Heating occurs due to the creation of a warm air curtain on the path of cold air penetration through the most vulnerable places. The principle of operation is similar to that of convective heating.
Criterias of choice
When choosing electric radiators, you should pay attention to the following criteria:
- Decide on the installation site. There are two ways to install the equipment - floor-standing and wall-mounted. Almost every wall modification can be converted to a floor version by equipping it with stable feet. Sometimes they do it differently - they remove the legs from the floor structures and hang them on the wall.
- Find out what tasks an electric convector is needed for. In this case, we are talking about the room in which the structure will work. For example, if the heating system is to be installed in a utility room or summer cottage, the device must be equipped with an anti-freeze function and / or resistance to low temperatures. If you neglect this, most likely, you will have to purchase new heating convectors from year to year. If the structure is intended for heating a residential building, apartment, you can get by with the simplest modifications.
- Power. This factor affects not only the heating rate of the convector, but also the amount of electricity consumed. In this case, you need to give preference to devices that will be powerful for heating the room, but at the same time economical. For example, with a consumption of 500 W / h, it will be possible to warm up a room with an area of 20-25 sq.
- It is necessary to pay special attention to the electronic filling and the materials used in the manufacture. Most of the models are made of aluminum. It is better to rely on a trusted manufacturer, otherwise you can buy a radiator of dubious quality.
- Temperature control. The device can be with a thermostat to control the temperature of the coolant, or monitor the temperature of the air around. In order to save money, it is preferable to choose the latter option.
Finally, it is worth mentioning the equipment with various options. This point is not fundamental, it all depends on the budget.
Saving energy without losing quality
It is worth highlighting the good reasons why you need to install electric heating at home.
- The creation of a multi-section heating system will not be too expensive, but the room will be well heated in the shortest possible time. It is worth mentioning separately about the installation, which does not cause difficulties even for beginners in this business.
- A closed heating system creates a favorable microclimate for households, and does not attract dust. The electrical structures are compact and do not take up large areas.
- Installing radiators near windows minimizes heat loss through window cavities.
- In severe frosts, this is a high-quality analogue of traditional batteries. Often used in accidents.
- The system is powered by a universal 220 V power source.
It is worth noting the absolute safety of the heating system used. This is due to the use of high quality and environmentally friendly materials for the manufacture.
