# Commission Decision of 1 March 2013 establishing the guidelines for Member States on calculating renewable energy from heat pumps from different heat pump technologies pursuant to Article 5 of Directive 2009/28/EC of the European Parliament and of the Council (notified under document C(2013) 1082) (Text with EEA relevance) (2013/114/EU), Division 3.9: Remarks to air sourced heat pumps

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

The HHP values shown in Tables 1 and 2 above are based on HHE values which includes not only the hours the heat pump is used, but also the hours that the supplementary heater is used. As the supplementary heater is outside of the system boundaries described in Section 3.4, the HHE values for all air source heat pumps are appropriately adjusted to only account for the useful heat delivered by the heat pump itself. The adjusted HHP figures are shown in Tables 1 and 2 above.
In the case of air sourced heat pumps with capacity reported for design conditions (and not for standard testing conditions), the HHE values should be used.
Only ambient air, i.e. outdoor air, can be the source of energy for an air-sourced heat pump.
