Wood pellet boilers are fully automatic just like oil and gas boilers. Pellet boilers use advanced microprocessors to control 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 almost as convenient as using oil. No supervision of the equipment is required, although the pellet-burner will need cleaning about once a month. At the same time the ash must be removed, although the quantity is small as the 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.
Since April 2001 wood combustion equipment has qualified for Enhanced Capital Allowances and a number of UK suppliers of pellet equipment have registered with the Inland Revenue so that customers can benefit from this allowance.
