Promoting Wood Pellet Stoves Promoting Wood Pellet Stoves and Boilersand Boilers

• Information on the website.• Publicity leaflets.• Information sheets and case studies.• Work with British BioGen to maintain and

update their existing database of wood pellet fuel suppliers and pellet fired heating appliances.

• Work with individuals and community groups to bring about the installation of wood pellet heating systems and stoves.


Wood PelletsWood Pellets

• Manufactured from waste products such as sawdust.

• No chemical additives needed.

• Low moisture content (6 -10%).

• High density.• Consistent size (usually

6 or 8mm).• Can be used in

automatic clean burn appliances.

•Now being manufactured in the UK.


Pellet StovesPellet Stoves

• First introduced in the USA in the 1980’s.

• Temperature and timer controls.• Fans that distribute warm air around

the room.• Automatic Ignition.• High efficiencies (up to 90%).• Hopper containing enough fuel for 1

to 3 days.

Pellet BoilersPellet Boilers

• Fully automatic.• Use advanced microprocessors to

control the amount of fuel and air supplied to the combustion chamber.

• Cope with variable load demands and can be operated on a timer.

• Very efficient producing only small amounts of ash.
