Water heating energy eciency of package under average climate
The energy ef ciency of the package of products provided for
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.
