Automatic wood chip, wood pellet boilers for central heating and hot water.

Central heating boilers with automatic wood chip feed systems

Heating with wood chips, wood pellets and sawdust/shavings, recovers energy on-site, safeguards local jobs in the surrounding region and offers an additional source of income for land and forest managers. The use of wood reduces our dependence on heating oil and natural gas. The burning of oil also produces higher sulphur dioxide and hydrocarbon emissions than the burning of wood chips. The transportation and storage of wood chips poses no threat to the environment. Heating with wood chips is ecologically responsible, as it has a virtually closed CO2 cycle. wood chips

Wood Chips

Wood chips are made from whole trees, branch wood or coppice products which have been mechanically shredded by a chipping machine. Ideally the wood needs to have been air-dried before chipping, or the chips dried before burning.

Shavings and Sawdust

Waste wood from manufacturing which has no additives such as wood planings and sawdust can be a perfect way to use a waste wood for heating. The compact range can burn wood pellets either as a dedicated fuel source or as an alternative. HDG logo compact 50 wood chip boiler compact 100 wood chip boiler Co2 cycle of wood chips
