Frequently Asked Questions

What are the key benefits of servicing?

There are many benefits of regular biomass boiler maintenance. These include:

  • 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
  • Increased heat output which also maximises RHI returns

How often should a 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. Because systems that are used for process heat will have much higher run hours, these boilers will need two or even three services per year.


How long does it take to service a 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 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

What is the HETAS Approved Biomass Maintenance Scheme?

The Scheme sets an accredited standard for the servicing and maintenance of Non-Domestic RHI eligible biomass boilers.

In 2019 BEIS commissioned research led by KIWA to evaluate the performance of biomass boilers in situ. This independent research conclusively proved that biomass boiler efficiency could be increased, and also that harmful emissions could be reduced. It recommended that an annual service, at a minimum, by an accredited business could help to improve biomass boiler performance and reduce harmful emissions.

The biomass industry, with the support of Micro Certification Scheme (MCS) and HETAS, consulted and created a Standard (MCS040), which details criteria for businesses conducting Planned and Preventative Maintenance (PPM) of biomass boilers to adhere to. HETAS was appointed to administer the Scheme. Only businesses achieving this Standard
gain accreditation.

As well as increasing the efficiency of the boiler and reducing the levels of emissions, the Scheme also provides assurance for RHI recipients that their boilers have been serviced to the right standard by fully qualified engineers.
