Fuel Types

One Tonne of Biomass can save up to 400 Litres of Oil!


Wood should, ideally, be stored for 18 months under cover and exposed to the wind. This reduces the moisture and the tarring it causes. Painted or treated timber may need an afterburner. Pallets can be filled with a variety of industrial by-products.


Rapeseed, linseed, or bean straw burns hotter and cleaner, wheat is preferred to barley. In winter, a 17kg small bale of straw will heat 2 radiators for 24 hours with enough spare to heat the hot water.

 Other Waste

Miscanthus, willow, poplar and other biomass such as vineyard prunings, rice husks and olive pips can be burned in a Dragon. An average house needs only a third of a hectare of willow.

 Animal Carcasses

Up to 50kg per hour of pig and poultry carcasses can be burned providing they were produced on the holding and the ash remains on the farm. Other animals can be burned with an afterburner to ensure complete combustion. We suggest you consult your local DEFRA Animal Health Divisional Office for further advice.
