Seasonal space heating energy efficiency class
Parameter
Rated heat output
For boiler space heaters and boiler combination heaters: useful
heat output
At rated heat output and high-
temperature regime (*)
At 30% of rated heat output and low-
temperature regime (**)
Auxiliary electricity consumption
At full load
At part load
In Stand-by mode
For combination heaters:
Declared load profile

Annual electricity consumption
(*) High-temperature regime means 60 °C return temperature at heater inlet and 80 °C feed temperature at heater outlet.
(**) Low temperature means for condensing boilers 30 °C, for low-temperature boilers 37 °C and for other heaters 50 °C return temperature (at heater
inlet).
