DECC/Ofgem will require some RHI installation to be monitored – but there are good reasons for monitoring all RHI installations, particularly air and ground source heat pumps. Housing Associations and Councils are installing heat pumpds to provide efficient heating and hot water for their tenants.
They all need to be monitored to ensure that they are working efficiently and that tenants and occupiers are comfortable and getting the benefit from the investment in the equipment.
Monitoring is also essential for establishing a robust evidence base about the performance of equipment so that Housing Association and others can develop future strategies with confidence. Monitoring is also the best industry improvement incentive there is.
RHI installs are grouped into Master projects (by streets or projects) for easy admin and visual checking.
Any heat pump that fails is immediately formatted in red, and one that begins to struggle in performance is highlighted in yellow. At the same time an automated email alert is sent to the client (or the client’s chosen maintenance company). Click images to enlarge
Free RHI monitoring:
Once the domestic RHI is launched, DECC/Ofgem will offer grants that cover the full cost of monitoring heat pumps installed in social housing. The monitoring requirements are complex and involve the use of data-loggers recording 1 minute data from heat meters and temperature sensors, etc. The data will have to be uploaded to a suitable web-platform in line with the relevant DECC/Ofgem data analysis specifications.
Energence is on the Ofgem RHI monitoring consultation forum, and offers a complete Metering and Monitoring Service Provider package for Registered Social Landlords and other clients.
Earthdome” flats, London Borough of Merton
The monitoring of this Ground Source Heat Pump provides a case study of how to monitor the Renewable Heat Incentive (RHI)
The heating and hot water needs of the flats are supplied by three ground source heat pumps, and one exhaust air source heat pump.
We track both the kWh generation and the electrical parasitic load used to run the heat pump – and in so doing identify the efficiency (COP/SPF1) of heat pumps.

Architect: Bob Harris:http://www.earthdomes.co.uk Earthdome is an icon eco-development, and the flats are built to very high thermal and ecological standards. In 2005 Bob won Master Builder of the Year for Earthdome.
The Earthdome project was created to demonstrate that it can be both practical and cost-effective to construct living environments that have minimal environmental impact, yet still provide a modern and fashionable lifestyle experience.
