# 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 3.10: Remarks related to reversible heat pumps

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

Firstly, reversible heat pumps in warm and to some extent average climates are often installed with the purpose of cooling the indoor environment, although they are also used to provide heating during the winter. As the cooling demand in the summer is higher than the heating demand in the winter, the rated capacity reflects the cooling demand rather than the need for heating. As the installed capacity is used as an indicator of heating demand, it implies that the statistics of installed capacity will not reflect the capacity installed for heating purposes. Moreover, reversible heat pumps are often installed in parallel to existing heating systems, implying that these heat pumps are not always used for heating purposes.
Both elements need appropriate adjustment. A conservative reduction to 10 % for warm climate and 40 % for average climate is assumed in Tables 1 and 2 above. However, the real reduction is strongly dependent on national practices for providing heating systems, and national figures shall therefore be used where possible. The use of alternative figures should be submitted to the Commission, together with a report describing the method and data used. The Commission will, if necessary, translate the documents and publish them on its transparency platform.
