How to choose an electric wall convector for home heating

Recommendation points



An electric convector is a universal heating device. As an additional heater, it can quickly raise the temperature to a comfortable level. And the accuracy of setting and regulating temperature modes allows you to create effective and fairly economical general heating systems.

The principle of operation and design of the electric convector

Any heating device uses two methods of transferring heat energy – convection and heat radiation. Electric heaters are no exception.

An electric convector directly heats the air and creates favorable conditions for natural convection, and thermal radiation can be considered as a concomitant factor.

The faster the room heats up, the more efficiently the heating works (at equal power values). In this regard, thermal fans are out of competition, but they have significant disadvantages – increased noise level, dust transfer and additional power consumption. The electric convector is devoid of these drawbacks, and the speed of movement of the heated air is high enough to quickly warm up the room to a comfortable temperature. This is achieved due to the features of the device.

The convector consists of the following elements:

  • a hollow body with an opening at the bottom for the intake of cold air, and at the top an outlet grill for warm air;
  • a heating element;
  • Control block;
  • thermostat;
  • temperature sensor.

The heating element is located at the bottom, near the inlet. And the hollow structure of the body, similar to the air duct, creates favorable conditions for increasing the air flow rate and quickly warming up the room.

Advantages and disadvantages

Electric wall convectors are easy to install and maintain. If this is an additional heating device, then it is enough that there is a socket nearby, designed for a maximum of 2.5 kW (this is the maximum power of one product).

To build an autonomous heating system based on several convectors, you only need to install a dedicated power line. But it is easier and cheaper than laying pipes, installing a boiler and a chimney to remove combustion products.

In terms of their dimensions and weight, they are one of the most compact and lightweight devices. For comparison: a 1.5 kW convector (medium size) in terms of heat output is equivalent to a hot water heating radiator of 10-12 sections and weighs no more than 7 kg.

Most models are designed for wall and floor mounting. Even if feet are not included, they can be purchased separately. This allows you to quickly change the heating scheme of the house – just remove the convector from the brackets, install it on the legs and move it to a specific room (or zone).

In comparison with other electric heaters, the following advantages can be indicated:

  • do not “burn” oxygen, like models with an open spiral;
  • do not carry dust and do not make noise like heat fans;
  • low case temperature (up to 65 ° C);
  • gentle operating mode of the heating element (in terms of temperature and operating time).

The convector has one drawback – it is the high cost of electricity. But this is inherent in all electric heaters. Although it is possible for convectors to save up to 25% of electricity – modern thermostats and heating control systems allow this..

Types of convectors

As a heating element, convectors use a heating element – a tubular electric heater.

The simplest and most inexpensive models use a U-shaped heating element. But having saved on cost, they lose on heating efficiency. The area of ​​contact with air for such a heater is not high, therefore, heat transfer also decreases..

The next are heaters consisting of a steel core, on which a radiator grill is installed. Their efficiency is much higher, but in this case there are drawbacks. The main one is the presence of contact between the two components (tube and radiator). Over time, it deteriorates, which leads to a decrease in the efficiency of heat transfer, violation of the thermal regime, local overheating and failure of the heating element.

Modern models use monoblock X-shaped heating elements. They not only have a large heat exchange surface – the solidity of the structure and optimal thermal conditions are the key to high durability.

Many experts consider combination heaters to be the most effective. This is the same X-shaped heating element, but with a ceramic coating. The porous surface of the plates has an even larger area of ​​contact with air. Plus, part of the thermal energy “goes” to the long-wavelength region of IR radiation, heating the surrounding objects, and “connecting” the secondary convection – thereby increasing the heat transfer area.

Separately, one can highlight glass convectors with a 9 mm transparent panel, inside which a special conductive gel is placed (it serves as a heating element). The simplest 0.5 kW model costs over 1,000 euros. It is expensive to build a heating system based on such devices, but as elements with high decorative properties in the high-tech style, they are very attractive.

Thermostats

The convector is controlled by a thermostat. According to the principle of operation, it can be mechanical and electronic.

A mechanical thermostat is the most inexpensive and simplest. Its action is based on the properties of a bimetallic plate. Temperature setting and control is the same as with a conventional iron. This also explains its disadvantages:

  • the case temperature is controlled, not the air temperature (“overheating” by 1 ° C leads to the consumption of additional electricity);
  • a click when the thermostat is triggered (this is uncomfortable for a bedroom);
  • manual adjustment (no programming and remote control function).

An electronic thermostat controls the air temperature using one or more sensors, reacting automatically when it changes by 1 ° C.

By placement, electronic thermostats can be built-in and remote. One thermostat can control the operation of several convectors.

Simple models are configured manually. They can have a wide menu with a timer function and the ability to program modes. The most “smart” units have an intelligent interface and are controlled remotely, including in energy-saving mode..

Convector use options

Stand-alone mode is suitable for small rooms or for convectors as an additional heater.

Group mode allows you to install one electronic thermostat (built-in or remote) for several convectors for heating large areas.

Remote control is possible for thermostats connected to the GSM module.

There are models of thermostats with the ability to integrate into a smart home system by connecting them to a controller with access to a router.
