3. General description
Dimensioning
An air/water-heat pump should be dimensioned in
such a way that the bivalence point lies between -3
the annual heating requirement (Austria, Germany,
Switzerland) will be covered by the heat pump.
In dimensioning the system the maximum heating
output of the house including the water for domestic
use is calculated.
The standard outside temperature is additionally re-
quired. This is determined by the geographical loca-
tion and can be found on the IDM homepage and ob-
tained from various institutions.
