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

The value of the seasonal space heating energy efficiency of the
preferential space heater, expressed in %.
The factor for weighting the heat output of preferential and supple­
mentary heaters of a package as set out in the following table.
The value of the mathematical expression: 294/(11 · Prated),
whereby 'Prated' is related to the preferential space heater.
The value of the mathematical expression 115/(11 · Prated),
whereby 'Prated' is related to the preferential space heater.
