Heat The Room with Convectors

Convectors: Heat is not transferred by radiation, but by direct transmission to the air molecules. For this reason, convectors can be covered or built in, without reducing the heat output.
Disadvantages: strong movement of air and the dust swirling effect; performance of convector depends on the height of the duct above the heated body; cross-sections of air flowing into and away from the convector must be of sufficient size.

Various installation options for convectors

The pictures above showed the various installation options for convectors. For under-floor convectors → ①f – ①h, the same prerequisites apply as for above-floor convectors. The disposition of the under-floor convectors depends on the proportion of heating requirement for the windows as a fraction of the total heating requirement of the room. Arrangement → ①f should be adopted if this proportion is greater than 70 %; arrangement → ①h for 20 – 70 %; if the proportion is less than 20 %, then arrangement → ①g is favoured.

Convectors without fans are not suitable for low-temperature heating, since their output depends on the throughput of air and, hence, on the temperature difference between the heated body and the room. The performance of convectors with too low a duct height (e.g. floor convectors) can be increased by the incorporation of a blower. Blower convectors are of limited use in living-room areas, due to the build-up of noise. Heaters can be covered in various ways. Losses in efficiency can be considerable, and attention should be paid to adequate cleaning. For metal cladding, the radiative heat contribution is almost entirely given to the room air. For material coverings with a lower thermal conductivity, the radiative heat is damped considerably.

This “Heat The Room with Convectors” is taken from the book Architects’ Data written by Ernst and Peter Neufert, whereas this book has become the guideline for architecture college students in the world.
