Burning
Pellets
There are two solutions to burn pellets, in either a pellet
boiler or stove. Not all pellet stoves and boilers can burn all types of pellets successfully. This
should be taken into consideration when choosing a raw
material, and purchasing a boiler or stove.

Maintenance
Ash Content
Different fuels, produce different amounts of ash. Wood for
example produces around 3%, and energy crops are generally
above this. A fuel that produces more ash, results in more
maintenance for the user, as they have to empty the ash pan
more frequently. Currently most stoves and boilers cannot
handle high ash content fuels.
Clinker
A clinker is a hard deposit material which is produced
through ash melting, this forms a mass of sticky material that
cools hard. If a material produces ash with a low melting
point, a clinker will form, and will have to be manually
removed, which increases maintenance.
Slag
Slag is similar
material to a clinker, which collects around the heat
exchanger pipes, and reduces heat exchange, and thus
performance, visit the
Raw
Material page for examples.

Corrosion
Sulphur
Sulphur is a low temperature corrosive, fuels which contain
above 0.1% will have an affect on corrosion within the
boiler over time at low temperatures, bare this in mind when
choosing a suitable boiler. Visit the
Raw
Material page for examples.
Chloride
Chloride is a high temperature corrosive, fuels which
contain above 0.1% will have an affect on corrosion within
the boiler over time at high temperatures, bare this in mind
when choosing a suitable boiler. Visit the
Raw
Material page for examples.
Burner Choice
All stoves and boilers have a limited life expectancy due to
corrosion. Corrosion should be taken seriously, particularly
if you wish to burn biomass other than wood. Visit the

Cost
Stoves
Pellet stoves are the cheapest option to burn pellets,
however you are limited to the the choice of biomass you
use. Stoves currently are specifically designed to burn wood
pellets alone. Prices start from around £2000, visit the
Links
page for more information.
Boilers
Pellet boilers are larger than stoves, and produce more
heat. Most pellet boilers currently are designed
specifically to burn wood pellets only. However there are a
few boilers in the market which have a broader perspective.
Prices start from around £4000, visit the
Links page for more information.
Support
Due to the positive effects on the environment from using
pellets, there are several grants and low interest loans
available to help home owners and businesses install boilers
and stoves. Visit the
