Convector heater - what is it ?An overview of all the features and types of flaws

assortment of heaters is quite large, so the choice of the optimal variant for a particular room is a certain complexity.Especially if you do not understand what the fundamental difference between them.In this article, we shall understand in detail what constitutes Convection heaters and what their main differences from peers.

The principle of

The term "convection" means that the heat transfer is carried out in the process of moving its carrier.The device unit is easy to understand from this figure.

heat exchanger raises the temperature of the incoming air from the bottom to the desired value (it is exposed thermostat), then it naturally rises to the ceiling.For this purpose, in the housing provided on the respective faces of the special "passages" - slots or holes.

order flow was directed, as well as to improve the heat transfer coefficient, the heating unit is provided with ribs.The scheme of air circulation in the room shown in the figure:

Types convectors

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

• Gas.
• Water.

As a rule, these models in a residential area is not used as the specifics of operation vary.

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

Features convector heaters

• Such heaters are safer - thermal burn can not be obtained, but not so on the oil cooler.This is due to the original engineering solution - the convector case and the heating element are completely isolated from each other.For families with small children - more than relevant.

• Can be mounted on the walls, which allows more efficient use of the usable area.Oil radiators do not set.

Although there are floor models and convector heaters in the bottom of which are wheels for easy reinstallation from place to place.

• temperature in the room rises quickly.Oil counterparts in this respect considerable inertia.

It's all a plus.Are there any disadvantages?

Disadvantages convection models

• Uneven warming height of the room.The difference can reach 10 ° C.For example, in the homes of old buildings, in large rooms with high ceilings.

• Together with the air rises and circulates dust, which can not affect the "ecological purity" in the room.Therefore, getting the convector to be understood that it is necessary or engage in cleaning the room more often, or in addition to buy another appliance - cleaner air, on the choice of which we have already mentioned.It can be compared with a vacuum cleaner, but it is designed specifically for the air to get rid of various microscopic suspensions.Such models can hardly be called cheap - from 6 000 rubles (if known by the manufacturer).

• dust gradually accumulates on the heat exchanger and starts to burn.It is eventually felt by a particular smell in the room, so convector, as opposed to the oil cooler needs regular maintenance.

If water gets inside, the result is known.And the dust will become attached element is not clear, it will have to change.For areas with excessive humidity buying pointless - or the unit will last a long time, or circuit breaker on the introduction of housing will continue to beat.

is, in principle, and all you need to know about the convector heater.But before you go to the store, you need to understand the criteria for the correct choice of instrument.Author stayed only one nuance, but there are other issues that should be considered.Example how to calculate the required power.But all this is - is a topic for another article.
