“III” : The value of the mathematical expression : 294/(11.Prated), whereby 'Prated' is related to
the preferential space heater.
“IV” : The value of the mathematical expression : 115/(11.Prated), whereby 'Prated' is related to
the preferential space heater.
(1) If tank rating is above A, use 0.95

Seasonal Space Heating Energy Efficiency Class Of Package
Seasonal space heating energy efficiency class of package
The energy efficiency of the package of products provided for in this fiche may not correspond to its actual energy efficiency once installed in
a building, as this efficiency is influenced by further factors such as heat loss in the distribution system and the dimensioning of the products
in relation to building size and characteristics.
