(a)it is a ground source heat pump;
(b)it generates heat using naturally occurring energy;
(c)in the case of a plant with an installation capacity of 45kWth or less, the plant meets the requirements in regulation 13;
(d)it has a coefficient of performance of at least 2.9; and
(e)in the case of a plant in respect of which an application for accreditation is made on or after the third relevant date—
(i)the plant is designed and installed to operate with a seasonal performance factor of at least 2.5; and
(ii)where the plant is capable of heating and cooling, a design heat load for the plant has been calculated in accordance with BS EN 12831:2003(1).
(2) Paragraph (3) applies where—
(a)an application for accreditation in respect of the plant is made on or after the third relevant date; and
(b)the plant was first commissioned on or after 4th December 2013.
