14.4 Package fiche - Medium-temperature heat pumps
Important
‘Medium-temperature application’ means an application where the
heat pump space heater or heat pump combination heater
delivers its declared capacity for heating at an indoor heat
exchanger outlet temperature of 55 °C.

Solar contribution
The energy effi ciency of the package of products provided for in this fi che may not correspond to its actual energy effi ciency once installed
in a building, as this effi ciency is infl uenced by further factors such as heat loss in the distribution system and the dimensioning of the
products in relation to building size and characteristics.
