Abstract
The sizing of surface, i.e. underfloor, wall and ceiling radiators is carried out with the same initial condition as in the case of convector radiators. Like a classical convector radiator, the surface radiator has to be selected in a manner that ensures the required heat output for design conditions, calculated according to [1]. There are, however, a few differences. In the first place, in the case of surface radiators the β correction factors are not taken into consideration in the form which is typical of convector radiators because the variant of the device location, screening, etc. is not defined.

Notes
- 1.
In Standard EN 1264 parameter n is treated as a sum of n and 1. Using this approach, in this case n = 1.0.
- 2.
Most often there are three layers, with aluminium foil inserted between the outer and inner plastic layers.
