number of eligibility criteria, which must be verified by Ofgem • To ensure this can be achieved readily: • Understand the RHI eligibility requirements • Plan for the RHI requirements as part of the design and installation process • Obtain and retain documentation from manufacturers and installers • Complete the application fully, with the correct evidence and level of detail, seeking support from a third party (e.g. installer) if appropriate • Ofgem can help – Enquiry service, Comprehensive Guidance by Topic, Summary Applicant Guidance Notes [links at end of presentation]
after 15 July 2009 •Equipment new at time of installation • Grants not received for purchase/installation of certain equipment (‘the installation’) • Medium of heat transfer must be liquid or steam - i.e. no direct air heating • MCS or equivalent EN45011 if installed capacity is 45kW or under – a requirement for solid biomass, heat pumps, and solar thermal •Biomass boilers must be designed to use biomass as the primary fuel source •No single domestics at present Definition of domestics: “single self contained premises used wholly or mainly as a private residential dwelling where the fabric of the building has not been significantly adapted for non-residential use” Key Eligibility Criteria
building for… • Space heating, hot water or carrying out a process (not electricity) • Definition of building • “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” • NB: must not generate heat for predominant purpose of increasing payments Eligible Heat Uses
- Combined Heat and Power (CHP) plant - More than one building involved in the heating system - ‘Ineligible heat uses’ on the heating system COMPLEX Need to meter all of: -Heat generated by eligible installation -Total eligible use of heat on system -Heat generated by all plants on heating system SIMPLE Only need to meter: -Heat generated by eligible installation No – none apply Yes – one or more apply Simple or Complex Metering? Simple or complex metering?
that is coming from the RHI-eligible installation – we can only pay for that fraction of the heat used for eligible purposes” SIMPLE “Just meter the heat generated – we can pay for all of it” Simple or Complex Metering? Simple or complex metering? Heat generated by RHI installation Heat generated by all plant on the heating system Heat used for eligible purposes x Heat generated by RHI installation
equivalent • Appropriately calibrated and installed: – Early site audits have identified significant issues with meter installation –Exercise caution in all cases, including where meters are installed: • Install in line with manufacturer instructions – careful in the vicinity of bends, pumps or valves, or where space is tight, or being outside • On non-water-only systems (e.g. Solar thermal systems with ‘glycol’/antifreeze; steam systems) • Meter placement for RHI payments • Independent Report on Metering Arrangements (IRMA) Metering eligibility
For each heat meter, we need to see the placement of: flow meter integrator both temperature sensors • Diagram should be clear to someone who’s never visited the site Building boundaries (and labelled buildings) Comprehensive key All heat sources labelled, and matching references in application Metering Schematics

arrangement for a complex installation where decentralised ineligible plants (in this example, fossil fuel boilers) are located on secondary heating circuits in separate buildings. Note that the flow meter can be placed in either the flow or return pipe. Red lines denote the hot flow pipes, and blue lines indicate the cool return pipes. This schematic has been annotated with a key, a table of meter specifications, and building names/boundaries, as discussed in Section 1.4 of Volume One’s appendix
