ANNEX VIIMeasurements and calculations

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

(d)The annual energy consumption QHE shall be calculated as the sum of:

  • the ratio of the reference annual heating demand QH and the active mode coefficient of performance SCOPon or active mode primary energy ratio SPERon; and

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