Log boiler's, unlike chip or pellet systems, require manual
handling, and they may, therefore, not be suitable for everyone,
but for those who have the resources and time they can be an ideal
low cost option (from domestic-sized situations upwards to
heating for larger spaces such as village halls with a heat output
need of 70-80 kW), especially where potential end users have
their own source of fuel. For those that wish a degree of
flexibility there are multi fuel boilers which can burn both log
(manual feeding) and pellets (automated feeding) so that if, for
example, you go away for a few days there can be heating and hot
water on your return.
The 33kW log boiler at Corpach, Lochaber, provides space heating
and hot water for one household. Estimated savings on heating
bills are £1350 per annum and the system may be eligible to receive
payments under the Renewable Heat Incentive.
