Plants where heat generation must be metered

13.—(1) The heat generated by the plant (“plant A”) must be metered if—

(a) plant A is not a solar thermal plant; and

(b) plant A falls within paragraph (2), (3), (4) or (5).

(2) Plant A falls within this paragraph where it provides heat to the same property as another plant (“plant B”), except where plant B—

(a) is a solar thermal plant;

(b) is designed and installed to heat only one room;

(c) captures heat from air which is expelled from a property and transfers that heat into fresh air entering that property without generating additional heat;

(d) is an immersion heater for a domestic hot water cylinder or is any other plant which solely generates heat for the purpose of heating domestic hot water; or

(e) is a supplementary electric heater which is controlled by the same control system as the control system governing plant A.

(3) Plant A falls within this paragraph where it is a biomass plant with an installation capacity which is not sufficient to provide space heating for all parts of the property to which it provides heat and its first commissioning date is on or after the relevant date.

(4) Plant A falls within this paragraph where the property to which it provides heat was occupied for less than 183 days in the 12 month period ending on its RHI date.

(5) Plant A falls within this paragraph where it is a heat pump and is capable of using a fuel when generating heat for an eligible purpose.
