1 NEF Renewables5 th June 03HEF Conference The Log Pile Project NEF Renewables A Department of The National Energy Foundation Sandra Hayes Senior Project Manager

2 NEF Renewables 5 March, 2003 Renewable Energy Training The Log Pile The Log Pile Promoting and aiding the use of wood as renewable energy A three year project ( ) supported by the Governments Environmental Action Fund

3 NEF Renewables5 th June 03HEF Conference Two Strands To promote the use of all types of wood fuel To promote specifically the utilisation of wood pellets in wood pellet boilers and stoves.

4 NEF Renewables5 th June 03HEF Conference Promoting Wood Fuel Expanding existing database of wood fuel suppliers. Website (www.logpile.co.uk)with an on-line search facility for those looking for a local supply of sustainable wood fuel. Expansion of existing Freephone service to make this information available over the phone ( ).

5 NEF Renewables5 th June 03HEF Conference Searching the Website

6 NEF Renewables5 th June 03HEF Conference Registering on the Website

7 NEF Renewables5 th June 03HEF Conference

8 NEF Renewables5 th June 03HEF Conference Promoting Wood Pellet Stoves and Boilers Information on the website. Publicity leaflets. Information sheets and case studies. Work with British BioGen to maintain and update their existing database of wood pellet fuel suppliers and pellet fired heating appliances. Work with individuals and community groups to bring about the installation of wood pellet heating systems and stoves.

9 NEF Renewables5 th June 03HEF Conference Wood Pellets Manufactured from waste products such as sawdust. No chemical additives needed. Low moisture content (6 -10%). High density. Consistent size (usually 6 or 8mm). Can be used in automatic clean burn appliances. Now being manufactured in the UK.

10 NEF Renewables5 th June 03HEF Conference Pellet Stoves First introduced in the USA in the 1980s. Temperature and timer controls. Fans that distribute warm air around the room. Automatic Ignition. High efficiencies (up to 90%). Hopper containing enough fuel for 1 to 3 days.

11 NEF Renewables5 th June 03HEF Conference Pellet Stoves (2)

12 NEF Renewables5 th June 03HEF Conference Pellet Boilers Fully automatic. Use advanced microprocessors to control the amount of fuel and air supplied to the combustion chamber. Cope with variable load demands and can be operated on a timer. Very efficient producing only small amounts of ash.

15 NEF Renewables5 th June 03HEF Conference Competitively Priced Heating Fuelpence per kWh Electricity LPG Oil Wood Pellets in bulk (figures courtesy of WelshBiofuels) Notes: 1.Based on price for heating oil in Wales Sept 02 2.Bulk is the term for pellets sold loose and usually stored in an external silo not in bags with a minimum quantity of 5 tonnes. 3.Figures exclude the Climate Change Levy from which wood fuel is exempt.

16 NEF Renewables5 th June 03HEF Conference The Earth Centre, Doncaster 2002 replaced existing log boiler with a EcoTec A3 25kW boiler from Sweden. Ash pan requires emptying after about two weeks use. Installed cost in the region of £7.5k + VAT. Uses 8mm wood pellets. Fed from a remote silo by 4m auger pipe.
