Wood Chip is usually available as the most cost effective energy source for you biomass boiler. Woodchip boilers are usually slightly more expensive than wood pellet boilers however this cost is typically offset with the lower cost of woodchip. Woodchip Biomass systems usually require large spaces for storage and access for vehicles to the chip store.
Wood pellets are made from compressed sawdust, wood shavings and other Biomass products.
They are uniform in shape and size and have a higher energy content than chip or logs, thus requiring less storage space.
Logs must be manually fed into the boiler and are less automated than Woodchip or Pellet Biomass Boilers. Their output depends much more on human input. If the wood isn't adequately seasoned, contains too much moisture or the air supply is reduced too early they will not burn efficiently and create excess smoke and tar.
