  "text": "(a)The seasonal space heating energy efficiency ηs,h shall be calculated on the basis of the seasonal primary energy ratio in heating mode SPERh , corrected by contributions accounting for temperature control and, for water/brine-to-water heat pumps only, the electricity consumption of ground water pump(s).\n(b)The seasonal primary energy efficiency ratio in heating mode SPERh shall be calculated on the basis of seasonal gas utilisation efficiency in heating mode SGUEh , the seasonal auxiliary energy factor in heating mode SAEFh taking into account the conversion coefficient for electricity CC.\n(c)The seasonal gas utilisation efficiency in heating mode SGUEh shall be based on the part load for heating Ph (Tj ) divided by the bin-specific gas utilisation efficiency when heating at partial load GUEh,bin , weighted by the bin-hours the bin conditions occurs, using the conditions set out below;\n(d)The SAEFh shall be based on the reference annual heating demand QH and the reference annual energy consumption for heating QHE ;\n(e)The reference annual heating demand QH shall be based on the design heating load Pdesign,h multiplied by the annual equivalent active mode hours HHE as set out in Table 29;\n(f)The annual energy consumption for heating QHE shall be calculated as the sum of:\n(1)the ratio of the reference annual heating demand QH and the seasonal auxiliary energy factor in heating mode in active mode SAEFh,on ; and\n(2)the energy consumption during thermostat-off, standby, off and crankcase heater mode during the designated season;\n(g)The SAEFh,on shall be based (insofar as relevant) on the part load for heating Ph (Tj ) and the auxiliary energy factor in heating mode at partial load AEFh,bin , weighted by the bin-hours the bin conditions occurs using the conditions set out below;\n(h)The conditions to calculate the SGUEh and the SAEFh,on shall take into account:\n(1)the reference design conditions set out in Table 24;\n(2)the European average heating season set out in Table 26;\n(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.",
