The heat meters need to be replaced after the end of their lifespan or after 10 years of operation even if their lifespan is longer.
On RHI accredited installations the replacement must be done by an MCS certified installer company, like ours.

The procedure is the following:

I am currently in the process of organising the second run of annual maintenance for biomass boilers systems.
I plan to visit all customers who registered earlier.

The heat source is the Smart 80 boiler, the heating system was open vented but we transformed it to closed system.

The old system was base on a coal fired back boiler which was not operating very efficiently. We replaced the old boiler with a Si20 back boiler from Stove Innovation. unfortunately the stove doesn’t have an MCS certificate, so we could not use the Boiler Upgrade Scheme.

The objective of project was to heat the water for the 5 outdoor batht tubs with solar thermal energy in the sommer and with wood in the winter.
