ANNEX VII
The amount of aerothermal, geothermal or hydrothermal energy captured by heat pumps to be considered to be energy from renewable sources for the purposes of this Directive, E_(RES), shall be calculated in accordance with the following formula: E_(RES) = Q_(usable) * (1 – 1/SPF) where Q_(usable)= the estimated total usable heat delivered by heat pumps fulfilling the criteria referred to in Article 7(4), implemented as follows: Only heat pumps for which SPF > 1,15 * 1/η shall be taken into account, SPF= the estimated average seasonal performance factor for those heat pumps, η= the ratio between total gross production of electricity and the primary energy consumption for the production of electricity and shall be calculated as an EU average based on Eurostat data.
