Over time, water heaters become a thing of the past, as a worthy replacement has come to them - an electric radiator. This article will discuss the varieties of such household appliances, the principle of their operation and prices.
Working principle
An electric radiator heats up the surrounding space through convection (creating a permanent air heat exchange in the room) or heat release.
Heating appliances are characterized by the fact that several elements interact simultaneously in them. Made in the form of plates of galvanized steel or copper electrodes are placed in the electrolyte. The current moving through the heating element quickly increases its temperature. As a result, the resulting heat is transferred to the working fluid, which can be mineral oil. It is characterized by good heat transfer, thanks to which this liquid effectively heats the surface of the heater to maximum performance.
Spheresapplications
Electric heating radiators are expedient in those rooms where, due to the cold outside, the temperature is low 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 interruptions often occur. 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 central heating.
Benefits
Heating with electricity has a number of undeniable advantages:
- Any electric radiator is powered by standard 220 volts.
- You can always make a multi-section system out of several radiators. And most importantly, this will not require large financial costs, and the premises will warm up as quickly as possible.
- Electric home radiators look aesthetically pleasing, so they will fit perfectly into any interior.
- Heaters are compact in size, so they do not take up much space. Their installation does not require additional equipment and special skills. In addition, they do not dry out the air.
- Radiators, equipped with special software, will serve as an ideal option for rooms that are limited in terms of power supply. With a good power source, heating devices will function even without direct human intervention.
- Electric radiator is environmentally friendly - it does not harm the environment during operation, does not create noise, and most importantly, there are no combustion products.
- This device is safe in every way.
- For each specific room, taking into account its area, you can set the optimal temperature and select the required number of sections.
- In winter, this is ideal, especially if there is an accident on the heating network.
- Using these heaters, you can heat those rooms where, according to safety regulations, it is forbidden to use other heat sources.
- If one device fails, the system will still function.
It is important to note that the heating system option must be chosen at the design stage of the building.
Classification
Currently, electrical heating appliances are quite in demand, they are produced in many countries, respectively, the range on the market is very diverse. By location and size, these devices can be divided into:
- electric wall-mounted radiators;
- ceiling appliances;
- floor devices.
There are other varieties, such as narrow baseboard appliances, glass, ceramic radiators, as well as devices placed in the floor structure.
Type
According to the method of transferring thermal energy and design features, the following types of data are distinguisheddevices.
- Electric convector.
- Electric oil cooler.
- Infrared heater.
- 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 their use, it is necessary to take into account the fact that the power of the heater should not exceed the power of the power source.
Convectors are designed according to the principle of natural airflow circulation. In other words, cold air is heated inside the heating element of the heating device, then it exits from the grate located in the upper part.
This type of device does not get hotter than 60°C. For this reason, they are used only to maintain a certain temperature in the room.
Oil appliances
Electric oil heating radiators outwardly resemble classic batteries, but their cavity is filled with oil heated to boiling point.
The main advantage of such a unit is the ability to heat up to a temperature of 100-150°C and heat the premises well. However, there is a significant drawback - the risk of getting burned from its surface.
There are various models of devices of this type: with installed thermostats and fans, allowing you to control the temperature in a room with a largethe number of sections. Therefore, when choosing electric oil heating radiators, you should consult with experts.
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 borne in mind that the low power and small size of the unit will not allow heating a large room. Therefore, this equipment is purchased in large quantities, evenly distributed over the ceiling of the premises.
Heat 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 maintaining the required temperature over large areas.
There are more disadvantages: the fan heater cannot be used in rooms with high humidity, oxygen is burned in the room during its operation, and a significant consumption of electricity is recorded.
Which radiator is best for home?
Regardless of whether you live in a country house or in a city apartment, the question of a comfortable life during the cold season isespecially acute. Buying and installing an electric heating radiator, wall, ceiling or floor standing, is the most effective way to protect against freezing during the colder months.
Power calculation
On average, to heat a 10 m space2 and a ceiling height of 3 meters, a 1 kW radiator will be required. If it is planned to use the heater as an additional heat source, the power of the device is selected depending on the temperature difference that needs to be compensated.
Also, when calculating, a number of the following factors should be taken into account:
- Thickness and material of exterior walls.
- Number of window openings, their location and size.
- Glazing type.
- Floor structure (especially the ceiling of the upper floor and the floor of the first floor).
Thus, when purchasing an electric heating radiator for wall, floor or ceiling, it is necessary to take into account possible heat losses. If you decide to approach the heating of the house thoroughly, then it is still 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.
Electric radiator: price
Consider the most popular models of electric radiators and their prices. Using the table, you can also calculate how many devices you need to heat a room with a standard wall height, just know its area.
| Name | Power | Type | Heatedarea | Installation method | Cost |
| ENSA P500T | 0.5 kW | infrared | 9 m2 | wall-mounted | 6 200 RUB |
| Runwin Tokio+ | 1.5 kW | infrared | 15 m2 | outdoor | 14,800 RUB |
| UFO Basic 1 800 | 1.8 kW | infrared | 18 m2 | wall-mounted, floor-standing | 5 100 rub. |
| Sencor SFH 8012 | 1.8 kW | fan heater | 18 m2 | outdoor | 3 300 rub. |
| Electrolux EON/M-4209 | 0.8 to 2 kW | oily | 20 m2 | outdoor | 3 900 rub. |

Conclusion
The range of modern heating equipment is quite wide - electric wall, floor, ceiling radiators, convectors, infrared heaters, etc. Therefore, summing up, it is worth noting that for heating one room you need only one electricheating device. 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.
