Unlike a gas boiler, a biomass appliance burns a solid fuel such as wood pellets or chips. Combustion therefore produces ash and deposits that make routine cleaning and maintenance an important part of reliable operation.
Combustion chamber and heat exchanger
Servicing requirements vary by manufacturer, but cleaning combustion areas and heat-exchange surfaces is commonly important because deposits can affect heat transfer and operation.
Fuel-feed equipment
A biomass installation can include stores, augers, feed motors and other fuel-handling components. Their condition and operation can be just as important as the boiler itself.
Ash handling
Ash accumulation needs to be managed according to the appliance design and manufacturer's maintenance schedule. Automated systems can reduce manual handling but do not remove the need for inspection.
System hydraulics and controls
Biomass boilers frequently work with buffer vessels, pumps and control strategies designed to manage boiler output and heating demand. Servicing should therefore consider the wider installation.
