Wood Pellets

• Now being manufactured in the UK.

• 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.

10
Pellet Stoves

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

• Notes
• Based on price for heating oil in Wales Sept 02
• Bulk is the term for pellets sold loose and
  usually stored in an external silo not in bags
  with a minimum quantity of 5 tonnes.
• Figures exclude the Climate Change Levy from
