Substitution of regulation 8 (eligible installations generating heat using heat pumps)8

For regulation 8 substitute—

Eligible installations generating heat using ground source heat pumps8

1

This regulation applies if the plant complies with all of the following requirements—

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 12831:20036.

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.

3

Where this paragraph applies, the requirement in paragraph (1)(b) is deemed to be satisfied where, in addition to using naturally occurring energy in the form of heat, the plant uses—

a

solar energy which has been gathered by any means (other than by a solar collector which is an accredited RHI installation) and is stored in the ground in the form of heat;

b

heat from space cooling or process cooling; or

c

heat from processes other than the generation of heat.
