scope:

This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement. The scope of this part is to standardise the: required inputs, calculation methods, resulting outputs, for heat generation by the following heat pump systems, including control, for space heating and domestic hot water production: electrically-driven vapour compression cycle (VCC) heat pumps, combustion engine-driven vapour compression cycle heat pumps, thermally-driven vapour absorption cycle (VAC) heat pumps, using combinations of heat source and heat distribution as listed in Table 1.
