Is a Biomass Boiler right for me?
Biomass Boilers are more suitable for properties not connected to mains gas and who have suitable space for storage.
There are a few key things to consider before installing a Biomass Boiler:
Wood and pellet boilers are larger than their gas or oil equivalents and as such a larger installation area is required.
Storage of Pellets
You will also need space to store your pellet fuel. Pellets can be “blown” in to an area using a hose off a truck or they come in 25kg bags. Either way you will need a dry area to store your pellets somewhere that is suitable for deliveries and also suitable for feeding the boiler. As a guide you will require approximately 2 – 6 cubic metres of space near where the boiler is sited to store the fuel.
Ideally the fuel storage area will be under cover, as it is important to keep fuel dry. High moisture content in the fuel reduces the efficiency at which it burns. If wood pellets get wet they turn to unusable mush.
Do you have somewhere to put the flue?
All pellet boilers require the installation of a flue. You will need a flue which meets current building regulations and the standards for the appliances: a new insulated stainless steel flue pipe or an existing chimney – though chimneys normally need lining to make them safe and legal.
Do you have a local fuel supplier?
Some companies now offer deliveries of pellets anywhere in mainland Britain; the supply of logs is much more variable.
