Commission Regulation (EU) No 813/2013 of 2 August 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for space heaters and combination heaters (Text with EEA relevance) (c. 813)

ANNEX I U.K. Definitions applicable for Annexes II to V

Definitions related to boiler space heaters, boiler combination heaters and cogeneration space heaters U.K.

(7) ‘fuel boiler space heater’ means a boiler space heater that generates heat by burning fossil fuels and/or biomass fuels, and which may be equipped with one or more additional heat generators using the Joule effect in electric resistance heating elements; U.K.

(8) ‘fuel boiler combination heater’ means a boiler combination heater that generates heat by burning fossil fuels and/or biomass fuels, and which may be equipped with one or more additional heat generators using the Joule effect in electric resistance heating elements; U.K.

(9) ‘type B1 boiler’ means a fuel boiler space heater incorporating a draught diverter, intended to be connected to a natural draught flue that evacuates the residues of combustion to the outside of the room containing the fuel boiler space heater, and drawing the combustion air directly from the room; a type B1 boiler is marketed as type B1 boiler only; U.K.

(10) ‘type B1 combination boiler’ means a fuel boiler combination heater incorporating a draught diverter, intended to be connected to a natural draught flue that evacuates the residues of combustion to the outside of the room containing the fuel boiler combination heater, and drawing the combustion air directly from the room; a type B1 combination boiler is marketed as type B1 combination boiler only; U.K.

(11) ‘seasonal space heating energy efficiency in active mode’ (η_son ) means U.K.

• for fuel boiler space heaters and fuel boiler combination heaters, a weighted average of the useful efficiency at rated heat output and the useful efficiency at 30 % of the rated heat output, expressed in %;

• for electric boiler space heaters and electric boiler combination heaters, the useful efficiency at rated heat output, expressed in %;

• for cogeneration space heaters not equipped with supplementary heaters, the useful efficiency at rated heat output, expressed in %;

• for cogeneration space heaters equipped with supplementary heaters, a weighted average of the useful efficiency at rated heat output with supplementary heater disabled, and the useful efficiency at rated heat output with supplementary heater enabled, expressed in %;

(12) ‘useful efficiency’ (η) means the ratio of the useful heat output and the total energy input of a boiler space heater, boiler combination heater or cogeneration space heater, expressed in %, whereby the total energy input is expressed in terms of GCV and/or in terms of final energy multiplied by CC; U.K.

(13) ‘useful heat output’ (P) means the heat output of a boiler space heater, boiler combination heater or cogeneration space heater transmitted to the heat carrier, expressed in kW; U.K.

(14) ‘electrical efficiency’ (η_el ) means the ratio of the electricity output and the total energy input of a cogeneration space heater, expressed in %, whereby the total energy input is expressed in terms of GCV and/or in terms of final energy multiplied by CC; U.K.

(15) ‘ignition burner power consumption’ (P_ign ) means the power consumption of a burner intended to ignite the main burner, expressed in W in terms of GCV; U.K.

(16) ‘condensing boiler’ means a boiler space heater or boiler combination heater in which, under normal operating conditions and at given operating water temperatures, the water vapour in the combustion products is partially condensed, in order to make use of the latent heat of this water vapour for heating purposes; U.K.

(17) ‘auxiliary electricity consumption’ means the annual electricity required for the designated operation of a boiler space heater, boiler combination heater or cogeneration space heater, calculated from the electric power consumption at full load (elmax), at part load (elmin), in standby mode and default operating hours at each mode, expressed in kWh in terms of final energy; U.K.

(18) ‘standby heat loss’ (P_stby ) means the heat loss of a boiler space heater, boiler combination heater or cogeneration space heater in operating modes without heat demand, expressed in kW; U.K.
