With oil and fossil fuel costs rising year on year woodfuel becomes more and more cost effective.







Fuel Suppliers
To see a list of fuel suppliers please go to hardware, installers, fuel suppliers page. Please note that you should check with the supplier for fuel costs and supply information.



Fact: Over the life of a boiler 80% of the cost is in fuel
Fact: Projects will stand or fall on fuel quality and service
Advice: Get involved in the design process. Don’t sign a supply contract until you are happy with the delivery mechanism.
Approximately: The average home uses about 10 tonnes of fuel a year - estimate half a tonne of fuel per kW per year. One tonne is about 1.5 - 2 cubic metres in size.

Chip Storage
Chip store design is an important aspect of successful chip storage.

Chip Store design is crucial to success, with 80% of the cost of wood heating during a typical life span of 25 years resting with the fuel - not installation, getting it right must be a priority from day one! We can say with some authority that talk of bagging, shovelling or wheel-barrowing woodchip, must be rejected straight away.

Beyond this, bear in mind the following golden rules:

*Minimise handling n Minimise transport
*Mechanise using available equipment (agricultural)
*Bulk process

There are a many ways to deliver woodchips as shown above, the correct solution will depend on the particulars of each site and the budget available. Below ground stores allow quick and efficient tipping, however, in areas of high water table a swimming pool rather than a chip store may be the result! SWWF is available to advise.
