This post is a summary, as relating to Eligible and Ineligible heat uses, solid biomass. Please be sure to read the full guidance and draft legislation in full before making an application.
Eligible Heat Uses
- Heating a space: the heating of rooms or other enclosed spaces within buildings, typically through the supply of hot liquid to heat emitters, such as radiators and under floor heating.
- Heating water: the heating of water for direct use, such as commercial and industrial hot water or for use in schools or hospitals. Heating hot water for domestic use is also permitted, provided that the eligible installation does not provide heat solely to a single, domestic premises. For more information on what constitutes a single, domestic premises, see section ‘Installations heating one single domestic premises are ineligible‘ in Chapter Four.
- Carrying out a process: the use of heat to carry out a specific process such as industrial cooking, drying (including drying of wood and other biomass fuels), pasteurisation58 or chemicals manufacture. It also includes heat that is subsequently used for cooling, e.g. passing renewable heat through absorption chillers. It does not include heat used for the generation of electricity.
Ineligible Heat Uses
- Heating of external surfaces to prevent frost or cold temperatures
- Underground heating of open external spaces, e.g. recreational facility
- Heating of open air or partially enclosed swimming pools.
The Regulations define a building as ‘any permanent or long-lasting building or structure of whatever kind and whether fixed or moveable which, except for doors and windows, is wholly enclosed on all sides with a roof or ceiling and walls’; you will need to ensure that your building meets both criteria and OFGEM will ask for information about the building(s) in which the heat is used as part of the accreditation process.
Some of the relevant circumstances are specified in Section 6 of the draft 1 guidance.
