"The
use of wood fuel to heat our homes isn't new. The way we do it today
has been modernised though. From a small room heater stove to a large
log gasification boiler Tweed Renewables can advise, design and install
your wood fuel heating system".
Log gasification boilers
Log gasification boilers can completely replace any existing fossil
fuel method of heating your home. They are batch fed which means that
the user has to manually stoke them everytime a burn is required. They
are used in conjunction with an appropriate accummulator tank that
stores the energy they produce during each burn.
Every
property has a heat load. Every property will have a hot water and
space heating requirement. Unlike a common gas or oil boiler, log
boilers can't fire and get up to temperature quickly enough to meet the
demands of modern living. To do this log boilers have to used in a
different way. When a log boiler is lit all it wants to do is burn the
fuel that it has been loaded with. Sometimes this can take a number of
hours. During this burn time the heat that the boiler generates is used
to charge up the accummulator tank to a temperature of around 85
degrees centigrade. The log boiler then dies back into ember
preservation mode and generates a very small amount of heat. Mean while
the accummulator has been fully charged and it is this that is used as
a heat source for the property. The heat from the accummulator is
regulated then pumped round the radiator or under floor heating circuit
as required. Domestic hot water is passed through a heat exchanger and
then blended to tap so giving constant temperature mains pressure hot
water.
The heat requirements of space heating and hot water leech
heat away from the accummulator tank and it starts to cool down. The
log boiler controls know this and can signal the user to re-stoke. With
ember preservation it is only necessary to load the logs, the boiler
does the rest, no lighting is necessary.

Room heater stove
A small room heater stove can
often be the easiest and most attactive method of heating your home
with wood fuel. They are easy to install into most properties and have
the lowest cost of any wood fuel stove. They can be installed in
an old open fire place nook or can be installed free standing
in a room. They are a versatile stove with many installation
options.
