* To be established by means of table 5 of Regulation 811/2013 in case of “assembly” including a heat pump to integrate the
boiler. In this case the boiler must be considered as the main appliance of the assembly.

The energy efciency of the package of products provided for in this che may not correspond to its
actual energy efciency once installed in a building, as the efciency is in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.
