Wood Chip boilers

Compact 100 biomass boiler cutaway view

Wood chip boilers operate similarly to fossil fuel boilers. When heat is needed, they automatically ignite, feed fuel to the fire, and shut off as required. Their automated functionality makes them an excellent alternative for those seeking a cost-effective and environmentally friendly option compared to traditional oil, LPG, or electric heating, while ensuring high comfort levels.

Wood chip boilers are typically more suitable for larger domestic and commercial applications, where the additional fuel savings can offset the slightly higher initial capital costs and the greater space and input required for fuel storage. Some models designed for wood chips are also capable of burning wood pellets, providing greater versatility in fuel options.

 

Benefits of a chip burning boiler;

  • Fully automatic control and feed systems
  • Automatic ignition and cleaning
  • Option of automatic weather compensation
  • Eligible for both the Domestic and Non- Domestic Renewable Heat Incentive Schemes
  • Wood chips offer an automated heating solution at a lower cost than wood pellets
  • Can utilise own/local woodland to provide fuel
  • Significant fuel savings over oil, LPG and electricity
  • Lambda controllers ensure high real-life efficiencies up to 93%
  • Designed for long operational life

Combustion Control

Wood chip boilers require automatic combustion control to adjust to the varying nature of wood chip as a fuel. The most advanced and efficient boilers encompass a lambda sensor to adjust the primary and secondary air for the highest possible efficiencies. The controller ensures the precise mix of fuel, primary air, and secondary air at all stages of combustion to ensure efficiencies of up to 93%.

Fuel Storage

Wood chip boilers require larger fuel stores than the equivalent sized wood pellet system. Fuel stores should be sized so as to allow the boiler to run for a minimum of approximately 4 weeks in the coldest weather without the need to replenish the store. A number of methods can be used to fill the fuel store and are dependent upon individual sites and equipment available.
