Division 4 CALCULATION EXAMPLE

United Kingdom

The table below show an example for a hypothetical Member State located in average climate conditions, which has 3 different heat pump technologies installed.

				Air to air(reversible)	Water to water	Exhaust Air to water
The Member State in this hypothetical example did a survey of installed reversible air to air heat pumps and concluded that the equivalent of 48 % of the installed reversible heat pump capacity were used fully for heating, instead of the 40 % assumed in these guidelines. The H_HP value is therefore adjusted up from 710 hours, which assumes 40 % and set out in Table 1, to 852 hours, which is representative for the estimated 48 %.

Editorial notes

X1: Substituted by Corrigendum to Commission Decision 2013/114/EU 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 (Official Journal of the European Union L 62 of 6 March 2013).
