Convector heater - what is it? Review of all features, types and disadvantages

The range of heating devices is quite large, so choosing the best option for a particular room causes a certain complexity. Moreover, if you do not understand what the fundamental difference between them is. In this article, let us examine in detail what convection heaters are and what are their main differences from analogues.

Principle of operation

The term "convection" itself means that the transfer of thermal energy is carried out during the movement of its carrier. The device is easy to understand from the figure.

The heat exchanger raises the temperature of the incoming air from below to the required value( it is set by a thermostat), after which it naturally rises upwards, to the ceiling. For this, special "passages" are provided on the corresponding faces on the corresponding faces - slots or holes.

To ensure that the flow is directional, as well as to increase the heat transfer coefficient, the heating block is provided with fins. The air circulation scheme in the room is shown in the figure:

Types of

convectors They are classified according to the type of "power supply".

  • Gas.
  • Water.

As a rule, these models are not used in residential premises, because they differ in the specific operation.




  • Electric. The most common( and purchased) version of convectors. For their operation, only the mains voltage is required.

Features of

  • convection heaters Such heaters are safer - a thermal burn can not be obtained, which can not be said about oil coolers. This is due to the original engineering solution - the convector cover and the heating element are completely isolated from each other. For families with young children - more than relevant.
  • The possibility of mounting on the walls, which allows more rational use of the useful area. Oil radiators are not installed in this way.

Although there are floor models of convector heaters, in the lower part of which are castors for easy reinstallation from place to place.

  • The temperature in the room rises fast enough. Oil analogues in this respect are much more inert.

This is all in plus. Are there any downsides?

Disadvantages of convection models

  • Uneven heating of the room in height. The difference can reach 10 ºС.For example, in old houses, in large rooms with high ceilings.
  • Dust rises and circulates with the air, which can not but affect the "ecological cleanliness" in the room. Therefore, acquiring a convector, it is necessary to understand that it is necessary or more often to clean the room, or in addition to buy another household appliance - an air purifier, the choice of which we have already written. It can be compared with a vacuum cleaner, only it is designed specifically to get rid of air from various microscopic suspensions. Such models are difficult to call cheap - from 6,000 rubles( if from a well-known manufacturer).
  • Dust gradually accumulates on the heat exchanger and begins to burn. This over time is felt by the specific smell in the room, so the convector, in contrast to the oil cooler, needs regular maintenance.
Note! The cost of floor models of convector heaters - from 2 100 rubles, wall - from 3 090. But when buying a convector to choose the cheapest model is inexpedient. A low price is a sign that an open type heater is installed in it( usually a spiral, over which an electric current passes).

If water gets inside, the result is known. Yes, and from the dusty element to clean it will not work, it is necessary to change. For rooms with excessive moisture, it is senseless to buy - or the device will not last for long, or the automatic protection device at the entrance to the dwelling will constantly knock out.

Here, in principle, and everything you need to know about convector heaters. But before you go to the store, you need to understand the criteria for the correct choice of the device. The author dwelled on just one nuance, but there are other points that should be taken into account. For example, how to calculate the required power. But all this is already a topic of a separate article.
