Pellet burning stoves were first introduced in the United States in the 1980's, with over half a million now installed.
Now available in the UK, pellet stoves have many of the advantages of fossil fuel heating systems but without the associated environmental damage. These include:
- Temperature and timer controls
- Fans that distribute warm air around the room
- Automatic ignition
- High efficiencies (up to 90%)
Space heating stoves
In addition, pellet stoves feature a hopper to hold enough fuel for 1 to 3 days of operation and an ash pan that needs to be emptied no more than once a month to once a year (depending on the model and the frequency of use) so they are much more convenient to use than a traditional open fire or stove.
Pellet stoves look similar to traditional wood burning stoves but use modern microprocessor controls to ensure an efficient and clean burning fire. Because they use thermostatic controls and fans to distribute warm air around the room they are safer than traditional stoves, which rely on radiated heat to warm the room, making the room temperature uneven and the body of the stove dangerously hot.
Modern wood pellet boilers are fully automatic just like oil and gas boilers. Pellet boilers use advanced microprocessors to meter the amount of fuel and air being supplied to the combustion chamber. This ensures extremely high efficiencies (up to 90%) and ultra-low emissions.
Heating with pellets is as convenient as using oil. No supervision of the equipment is required, although the pellet-burner may need cleaning about once a month. Some models require the ash to be removed although the quantity is small as pellets burn very efficiently.

Unlike some other types of wood fuel heating, pellet boilers are well suited to meet variable load demands and can be operated on a timer.
