Pellet
baskets work with your existing solid fuel stove
or open hearth. |
|
- A Pellet Basket filled with
3kg of wood pellets corresponds to an energy
value of about 15kWh, at a cost of about £1.00.
- It will keep heating for up
to 4 hours depending on the kind of fireplace
and the adjustment of the draw.
- The greater the efficiency
of the burner the greater the burn efficiency
of the pellets.
|
|
- The Pellet Basket is easy to
use and handle. It can easily be put into and
taken out of the fireplace.
- The small quantity of ash generated
is easily shaken out through the grated bottom
of the basket.
|
|
- A Pellet Basket filled with
wood pellets will burn for half the time with
real flames, after which it becomes a bed of
hot embers.
- The grid for the air intake
on the sides of the basket gives a warming and
relaxing light.

First
introduced in the United States in the 1980's,
pellet burning stoves have rapidly increased in
popularity around the world.
They 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%)
|
|
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's temperature uneven and the body
of the stove dangerously hot.

Heating
with a pellet boiler is almost as convenient as
using oil. No supervision of the equipment is
required, and if a pellet storage tank is installed
fuel delivery to the boiler is automatic, just
as with an oil or LPG fired boiler. Likewise the
fuel is delivered in bulk by lorry, which blows
the pellets into the storage tank.
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.
The ash will need removing about
once a month, although the quantity is small as
wood pellets burn very efficiently. Ash removal
takes a matter of seconds and the ash can be used
in the garden compost, so there is no wastage.

It
is particularly important when installing a wood
pellet boiler that the installer works with the
pellet supplier from an early stage. This ensures
that the specifications of the fuel store and
other elements of the fuel delivery and supply
are adequately dealt with during the installation.
As a wood pellet supplier Harvest
Wood Fuels work with several wood pellet boiler
installers and can recommend an appropriate installer
for your installation. Please contact
us with details of your needs.

the Low Carbon Buildings programme, through which
you can access a grant of up to £1,500 for
the installation of a wood pellet boiler. |

The
cost of installing a wood pellet burner is higher
than conventional burners. However, with the price
of oil and other fossil fuels rising rapidly,
wood pellets have become much more competitive,
and are now significantly cheaper than oil or
LPG, and are on a par with mains gas.
This means that the extra cost
of installing a wood pellet burner is usually
paid back within 5 years, and the running costs
will only continue to become more competitive
against fossil fuels.
Within each category of boiler
(gas, oil, wood etc) there is a wide range of
costs depending on size, efficiency, make, model
etc.
The following is therefore given
as a general indication only of what one might
expect to pay for the type of boiler that would
heat a typical three bed semi (around 15kW), excluding
VAT: |

A
grant for the installation of pellet stoves (up
to £600) and boilers (up to £1,500)
is available through the Low Carbon Buildings
Programme – click

Also in the UK wood combustion
equipment qualifies 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. |
