TECHNICAL DATA
DOUBLE FUNCTION HEATING INSTALLATION PACKAGES,
TEMPERATURE REGULATOR AND SOLAR DEVICE
The package leaflet for dual-function heating, temperature controller and
solar device packages shall contain the elements referred to in points (a)
and (b):
a) the elements provided in figure 1 for the evaluation of the seasonal
energy efficiency related to the space heating of a dual-function heating
installation package, temperature controller and solar device, including
the following information:
- I: the value of the seasonal energy efficiency related to the heating of
the premises of the heating installation with preferential double
function, expressed in%;
- II: the weighting factor of the preferential and additional heating
installations in a package, (see DELEGATED REGULATION (EU)
No 811/2013 - Annex IV - 6.a);
- III: the value of the mathematical expression: 294 / (11 · Prated), where
Prated refers to the heating system with a preferential dual function;
- IV: the value of the mathematical expression 115 / (11 · Prated), where
Prated refers to the heating system with a preferential dual function;
