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