Wood pellets are usually produced from waste wood such as sawdust, which is compressed into pellet form.

The naturally occurring lignin in the wood creates a waxy external layer upon processing, however the pellets are composed of entirely natural substance.

The high-density of wood pellet makes these systems ideal for upgrading properties which have previously been on oil or LPG. Of all biomass fuels, they require the least space for fuel storage, making wood pellet boilers well suited to installation in existing outbuildings or garages.

Wood pellets can be bought in 10kg bags for hand-feeding, or in bulk deliveries of up to 18 tonnes for automatic boiler fuelling. Wood pellets can be transported from store to boiler by auger, suction hoses or by hand.

Wood pellets should always be of EN Plus standard, and bought from a reputable supplier on the Biomass Suppliers List.

Why wood pellet?

  • Economical as mass produced by various suppliers
  • Small and compact unlike other biomass fuels such as wood chips.
  • Sustainable through a balance between cutting and planting trees, with strict trading standards.
  • Low moisture content (typically 6 – 8%) compared to the humidity content of wood chips (30-35%).
  • Biodegradable and bound with lignin.
  • 90%+ less net carbon emissions than natural gas.

Wood pellet carbon footprint

Trees harness solar energy and atmospheric carbon that converts to carbohydrate energy which can be released when we need it.

Wood absorbs as much carbon when it is growing as is released when it is burnt. Provided that at least as much is grown back as is cut, wood is assumed to be a carbon-neutral energy source. The fossil-carbons released due to the production and transportation differ from one pellet factory to another.

The wood pellet system Boiler

  • Compact size
  • Automatic flue gas cleaning
  • Integrated ash container
  • Electric twin ignition element
  • Automatic ash removal
  • 135kg boiler hopper
  • Automatic vacuum fuel feed
  • Gasification burn process

Controls

  • MES (master) controller with weather compensation
  • Sensor reads external temp and internal temp and learns how the building reacts to external temp changes
  • More efficient as the heating system becomes proactive rather than reactive.
  • Point of use controller for each heating zone

Accumulators

  • Very efficient- 21% less heat loss than conventional cylinder.
  • Allow the boiler to run at maximum output when there is a low heat demand, increasing system efficiency.
  • Allow for additional boilers to be connected to the system in the future should heat demand increase.
