Servicing & Maintenance

Quality, Experience, Expertise



Regular servicing & maintenance to your biomass boiler isn’t just a precautionary task, it’s a legal and contractual obligation.


Our fully qualified and HETAS registered engineers will perform checks to ensure your biomass boiler meets all of the legal requirements.


As servicing partners for leading brands, such as Fröling our annual biomass boiler service will keep your manufacturer warranty valid. Should Ofgem audit your system, our Health Plus Biomass Boiler service reports are proof of your compliance to RHI rules.

Regular biomass boiler servicing & maintenance can:

  • + reduce the risk of a breakdown
  • + help reduce the risk of carbon monoxide emissions
  • + help to prolong the life of your biomass boiler.


Without yearly servicing & maintenance…

  • x your manufacturer warranty is void
  • x your RHI payments could be suspended (ofgem require proven annual maintenance records)
  • x ash and tar can build up in your biomass boiler, preventing heat from being properly transferred, making it less efficient

Regular servicing & maintenance is vital to the smooth running and performance of any heating system.

Biomass boilers are classed as solid fuel appliances and as such produces a waste product – ash. Ash is a highly insulative material, and as it moves through the boiler with the gases, is coats steel surfaces and reduces heat transference.

Did you know that 1mm build up of soot equals 10% loss in efficiency?

Therefore it is important that a biomass boiler be cleaned regularly (at least once a year, or around 2,500 running hours, whichever comes first). A warning sign of reduced efficiency is an increase in flue gas temperature as the heat produced is not being transferred correctly and is exiting through the flue.
