Commission Delegated Regulation (EU) No 811/2013 of 18 February 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of space heaters, combination heaters, packages of space heater, temperature control and solar device and packages of combination heater, temperature control and solar device (Text with EEA relevance) (c. 811)

ANNEX VII U.K. Measurements and calculations

4. Seasonal space heating energy efficiency and consumption of heat pump space heaters and heat pump combination heaters U.K.

(a) For establishing the rated coefficient of performance COP_rated or rated primary energy ratio PER_rated , or the sound power level, the operating conditions shall be the standard rating conditions set out in Table 9 and the same declared capacity for heating shall be used. U.K.

(b) The active mode coefficient of performance SCOP_on for average, colder and warmer climate conditions shall be calculated on the basis of the part load for heating Ph(T_j), the supplementary capacity for heatingsup(T_j) (if applicable), and the bin-specific coefficient of performance COPbin(Tj) or bin-specific primary energy ratio PERbin(T_j), weighted by the bin-hours for which the bin conditions apply, using the following conditions: U.K.

• the reference design conditions set out in Table 10;

• the European reference heating season under average, colder and warmer climate conditions set out in Table 12;

• if applicable, the effects of any degradation of energy efficiency caused by cycling, depending on the type of control of the heating capacity.

(c) The reference annual heating demand Q_H shall be the design load for heating Pdesignh for average, colder and warmer climate conditions, multiplied by the annual equivalent active mode hours H_HE of 2 066, 2 465 and 1 336 for average, colder and warmer climate conditions, respectively. U.K.

(d) The annual energy consumption Q_HE shall be calculated as the sum of: U.K.

• the ratio of the reference annual heating demand Q_H and the active mode coefficient of performance SCOP_on or active mode primary energy ratio SPER_on ; and

• the energy consumption for off, thermostat-off, standby, and crankcase heater mode during the heating season.

(e) The seasonal coefficient of performance SCOP or seasonal primary energy ratio SPER shall be calculated as the ratio of the reference annual heating demand Q_H and the annual energy consumption Q_HE . U.K.

(f) The seasonal space heating energy efficiency η_s shall be calculated as the seasonal coefficient of performance SCOP divided by the conversion coefficient CC or the seasonal primary energy ratio SPER, corrected by contributions accounting for temperature controls and, for water-/brine-to-water heat pump space heaters and heat pump combination heaters, the electricity consumption of one or more ground water pumps. U.K.

(g) The annual energy consumption Q_HE in kWh in terms of final energy and/or GJ in terms of GCV shall be calculated as the ratio of the reference annual heating demand Q_H and the seasonal space heating energy efficiency η_s . U.K.
