As of 1st April 2022, biomass boilers must now be serviced by an approved HETAS engineer and they must meet the HETAS 030 Biomass Maintenance Standard. HETAS is a non-profit organisation which is committed to helping people make cleaner and safer choices in the use of biomass and other solid fuels and technologies. All of our biomass engineers are fully HETAS registered to service GlenFarrow, Heizomat and all other types of biomass boilers accredited to the Renewable Heat Incentive to prove they are being properly maintained.
