Wood chips are again completely natural and are made from both waste wood and sustainable virgin timber. Wood chip biomass systems are more suitable for larger applications and for those who can utilize a local source or their own wood supply to make the chip.
For high efficiency, wood chip needs to be consistent in size and stored in a covered area that allows air to circulate and naturally dry the chip. Wood chips offer the cheapest form of automated biomass heating.
