Electric radiator: types, classification, prices. Calculation of the required power

Over time, water heating appliances go to the past, as they have come a worthy replacement - an electric radiator. In this article, we will consider varieties of such household appliances, the principle of their operation and prices.

Principle of operation

The electric radiator heats the surrounding space by convection (creating a permanent air heat exchange in the room) or the release of heat.

Heating devices are characterized by the fact that several elements interact in them simultaneously. Electrodes made in the form of plates of galvanized steel or copper are placed in the electrolyte. The current flowing through the heating element rapidly increases its temperature. As a result, the heat is transferred to the working fluid, which can be mineral oil. It is characterized by good heat transfer, due to this, this liquid effectively heats the surface of the heater to the maximum values.

Applications

Electrical heating radiators are advisable in those rooms where, due to the cold on the street, a low temperature at a time when the heating season has not yet begun. It also happens that the heating system does not function properly.

These devices are relevant in buildings equipped with modern heating systems, where various faults occur frequently. For this reason, it is necessary to maintain the required temperature regime. In this case we are talking about cottages, country houses and apartments with centralized heating.

Benefits

Heating with electricity has a number of undeniable advantages:

• Any electric radiator is powered from standard 220 volts.
• From several radiators it is always possible to make a multisection system. And most importantly, this does not require large financial costs, and the premises will be heated as quickly as possible.
• Radiators for the house electrical look aesthetically pleasing, so they fit perfectly into any interior.
• Heating appliances are compact in size, therefore, do not take up much space. Their installation does not require additional equipment and special skills. In addition, they do not overdry the air.
• Radiators, equipped with special software, will be ideal for premises that are limited in terms of supply network. If there is a good source of power, the heating devices will function even without direct human intervention.
• The electric radiator is environmentally safe - at work it does not harm the environment, does not create noise, and most importantly, there are no combustion products.
• These devices are safe in every sense.
• For each particular room, taking into account its area, it is possible to adjust the optimum temperature and select the required number of sections.
• In winter, this is an ideal option, especially if an accident occurred on the heating network.
• With the help of these heaters, it is possible to heat those rooms where it is forbidden to use other heat sources in accordance with safety regulations.
• If one device fails, the system will still function.

It is important to note that the variant of the heating system must be selected at the design stage of the building.

Classification

At present, electrical heating appliances are quite in demand, they are produced in many countries, accordingly, the assortment on the market is very diverse. In terms of location and size, these devices can be divided into:

• Radiators electric wall;
• Ceiling devices;
• Floor devices.

There are other varieties - for example, narrow skirting devices, glass, ceramic radiators, as well as devices placed in the construction of the floor.

A type

The following types of these devices are distinguished by the method of heat energy transfer and by design features.

• Electric convector.
• The radiator is an oil electric.
• Infrared heater.
• Fan heater.

Electric convectors

The main advantage of electric convectors is the ease of installation and use (it is enough to have an electrical outlet nearby). In the process of using them, it is necessary to take into account the fact that the capacity of the heater should not exceed the power of the power source.

Convectors are designed according to the principle of natural circulation of air flow. In other words, the heating of cold air takes place inside the heater's heating element, then it exits from the upper part of the grate.

Devices of this type do not heat up to a temperature of more than 60 ° C. For this reason, they are used only to maintain a certain temperature in the room.

Oil devices

Oil heating radiators are outwardly reminiscent of classic batteries, but their cavity is filled with oil heated to the boiling point.

The main advantage of such an aggregate is the ability to heat up to a temperature of 100-150 ° C and to heat the premises well. However, there is a significant drawback - the risk of getting a burn from its surface.

There are various models of devices of this type: with installed thermostats and fans, which allow to regulate the temperature in a room with a large number of sections. Therefore, when choosing oil heating radiators electric, it is worth consulting with specialists.

Infrared radiators

These heating devices are presented in the form of rectangular panels, which are fixed on the ceiling. Heating in radiators occurs by converting thermal energy into electromagnetic waves in the infrared spectrum.

When choosing infrared radiators, it should be taken into account that the low power and small size of the unit will not allow heating the large room. Therefore, this equipment is purchased in large quantities, evenly distributed over the ceiling of the premises.

Thermal fan

This device consists of two main elements: a fan and a heater. Due to the fan, the air flow passes through the heating element or a special chamber. The heated air is moved by the fan and enters the room.

The main advantages of this equipment are fast heating of the room and support of the required temperature in large areas.

The disadvantages are more: the fan heater can not be used in rooms with high humidity, oxygen is burned in the room, a significant consumption of electricity is fixed.

Which radiator is best for home?

Regardless of whether you live in a suburban private house or in a city apartment, the issue of a comfortable life during the cold season is particularly acute. Buy and install an electric heating radiator wall-mounted, ceiling or floor heating - this is the most effective way to protect against freezing in the cold months.

Power calculation

On average, a radiator with a capacity of 1 kW is required to heat a room of 10 m ² and a ceiling height of 3 m. If it is planned to use the heater as an additional source of heat, the power of the device is selected depending on the temperature difference that needs to be compensated.

Also in the calculation should take into account a number of the following factors:

• The thickness and material of the outer walls.
• Number of window openings, their location and size.
• Type of glazing.
• The construction of the ceiling (in particular the ceiling of the upper floor and the floor of the first).

Thus, buying an electric heating radiator wall, floor or ceiling, it is necessary to take into account possible heat losses. If you decide to approach the heating at home thoroughly, it is advisable to consult with specialists who will determine where and what devices should be installed and take into account the architectural features of the building.

Radiator: price

Consider the most popular models of electric radiators and the prices for them. Using the table, you can also calculate how many appliances you need to heat the room with the standard height of the walls, it is enough to know its area.

Conclusion

The assortment of modern equipment for heating is quite wide - radiators electric wall, floor, ceiling, convectors, infrared heaters, etc. Therefore, summing up, it is worth noting that for heating one room will need only one electric heater. And if you install it next to the window, you can prevent unnecessary heat loss - the thermal curtain formed in this place will provide comfortable conditions in the room.
