From fiche of heat pump
The energy efficiency of the package of products provided far in this fiche may not correspond to
its actual energy efficiency once installed in a building, as the efficiency is influenced by further
factors such as heal loss in the distribution system and the dimensioning of the products in rela-
tion to building size and characteristics.
