Why Do You Need to Have a Boiler Serviced?

An annual boiler service is essential to maintain your eligibility for Renewable Heat Incentive (RHI) payments. GlenFarrow recommend that all their boilers are serviced annually to ensure the most efficient operation, minimise the possibility of breakdowns and keep the boiler in a safe state for operation. The RHI Guidelines Volume 2: Ongoing Obligations & Payments, item 2.6 Maintenance of Equipment states “As an ongoing obligation, participants who own heat generating installations are required to maintain their equipment to ensure that it is working effectively. Ofgem requires equipment to be maintained in line with manufacturer’s instructions…..Participants will need to keep any evidence of maintenance work carried out, for example service receipts and to provide them with this evidence on request”. When we service any equipment we will provide full documentation for your records.

How Often Should a Biomass Boiler be Serviced?

Boilers should be serviced annually. This regular process will ensure the boiler will continue to work at the optimum level, be safe and will help to minimise the possibility of breakdowns.

How long will my Service Take?

We recommend that you allow a full day for your Biomass Boiler Service.
