Biomass Boiler Servicing & Maintenance
Frequently Asked Questions
How often should a Gilles biomass boiler be serviced?
An annual service is mandatory to comply with Renewable Heat Incentive (RHI) regulations.
Most biomass boilers will need to be serviced once a year, ideally in the summer when the boiler is not in such high demand. Systems that are used for process heat will have much higher run hours, so these boilers will need two or even three services per year.
How long does it take to service a Gilles biomass boiler?
Our expert engineers will take one to two days to perform a boiler service depending on the size of the biomass boiler installation. It will take around a day to service most 50 to 250kW boilers. Larger 500kW to 1MW boiler systems will take longer, probably around two days.
What are the key benefits of servicing?
There are many benefits of regular biomass boiler maintenance. These include:
• Increased heat output which maximises RHI returns
• Maximise system efficiency to reduce fuel consumption and costs
• Extended boiler and part life through regular care
• Increased reliability
• Minimise downtime and the risk of boiler breakdown
What does a biomass boiler service involve?
Each service can vary slightly depending on the type of biomass boiler, but all cover the following:
• a general inspection
• cleaning of airway ports
• inspection and cleaning of the heat exchanger and combustion chamber
• all seals and bearings checked, replaced and/or greased where necessary
• replacement of worn components
• inspection and testing of all safety equipment
• inspection of associated fuel equipment
• flue gas analysis to check combustion efficient
