# Commission Regulation (EU) 2016/2281 of 30 November 2016 implementing Directive 2009/125/EC of the European Parliament and of the Council establishing a framework for the setting of ecodesign requirements for energy-related products, with regard to ecodesign requirements for air heating products, cooling products, high temperature process chillers and fan coil units (Text with EEA relevance), Division 6: Seasonal space heating energy efficiency of electric heat pumps:

Extent: E+W+S+N.I.

(a)For the purposes of the measurements of heat pumps the indoor ambient temperature shall be set at 20 °C;
(b)While establishing the sound power level, the operating conditions shall be the standard rating conditions set out in Table 16 (air-to-air heat pumps), Table 19 (water/brine-to-air heat pumps);
(c)The active mode seasonal coefficient of performance SCOPon shall be calculated on the basis of the part load for heating Ph(Tj), the electric back-up heating capacity elbu(Tj ) (if applicable) and the bin-specific coefficient of performance COPbin (Tj) and weighted by the bin-hours the bin conditions occurs, and shall take into account:
(1)the reference design conditions set out in Table 24;
(2)the European ‘average’ heating season set out in Table 26;
(3)if applicable, the effects of the degradation of the energy efficiency caused by cycling depending on the type of control of the heating capacity;
(d)The reference annual heating demand QH shall be the design heating load Pdesign,h multiplied by the equivalent active mode hours for heating HHE set out in Table 29;
(e)The annual energy consumption for heating QHE shall be calculated as the sum of:
(1)the ratio of the reference annual heating demand QH and the active mode seasonal coefficient of performance SCOPon; and
(2)the energy consumption for thermostat-off, standby, off and crankcase heater mode during the season;
(f)The seasonal coefficient of performance SCOP shall be calculated as the ratio of the reference annual heating demand QH and the annual energy consumption for heating QHE ;
(g)The seasonal space heating energy efficiency ηs,h shall be calculated as the seasonal coefficient of performance SCOP divided by the conversion coefficient CC, corrected by contributions accounting for temperature control and for water/brine-to-air heat pumps only, the electricity consumption of ground water pump(s);
(h)For multi-split heat pumps the measurement and calculations shall be based on the performance of the outdoor unit, with a combination of indoor unit(s) recommended by the manufacturer or importer.
