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