Seasonal central heating energy efficiency class of the set
Boiler and supplementary heat pump installed with low temperature heat emitters
at 35 °C?
From the board of the heat
pump.
The energy efficiency of the set of products indicated in this fiche may not reflect the actual energy
efficiency after installation since such efficiency is affected by additional factors, such as the heat loss
in the distribution system and the size of the products compared to the size and features of the building.
