The electricity consumed

The electricity consumed by the heat pump, WHP, is measured continually while the produced space heating is measured at five “performance tests” done at different outdoor temperatures. During the performance tests the heating capacity of the heat pump is measured during stable conditions and is thereby not including any defrost period. Therefore the calculated COP for each test point is based on data from only a part of the operating cycle.  
The total amount of heat produced during the total measuring period needs to be calculated based on the five performance tests. The calculations are made as follows
