Heat metering publication updated

B&ES Publications has revised its Guide to Good Practice: Heat Metering for the RHI following changes to the scheme and also incorporate some of the lessons learned since its launch.

Designed for specifiers, installers and operators to meet the heat metering requirements of the non-domestic Renewable Heat Incentive Scheme, it was originally published following concerns over the use of heat meters.

Presented in 10. easy-to-read chapters, the Guide to Good Practice: Heat Metering for the RHI includes a clear index of specific and relevant information.

It covers the design, specification, installation, commissioning, and operating of heat meters, as well as data collection, inspecting and auditing.

It also includes six case studies outlining real-world insights into the installation of biomass boilers, ground-source heat pumps, and solar thermal systems, along with details of further recommended reading and useful websites.

Former Head of B&ES Technical and Safety BobTowse, said: “The RHI provides a continuous income stream for 20 years to any organisation that installs an eligible renewable heating system, but this depends on meeting the OFGEM criteria.

“Meter installations have to satisfy requirements on suitability, positioning, installation, calibration, and accuracy - and they can be subjected to rigorous auditing by OFGEM after they’ve been accredited. Our new technical guide gives crucial guidance on how to avoid falling foul of these requirements.”

The sums paid out to users by OFGEM under the RHI depend solely on data taken from heat meters, which must record the eligible heat generated by the equipment.

The book’s introduction issues a warning that the lack of fiscal heat metering experience among specifiers, installers and operators in the UK means that care must be taken to ensure all of the factors affecting heat meter accuracy are fully addressed.

If not, this puts at risk the delivery of reliable data and the entitlement to RHI pay-outs, says the guide.
