The energy efficiency of wood as a fuel source

The Scottish Government launched the Conserve and Save: Energy Efficiency Action Plan on 6th October 2010, with a headline target to reduce total energy consumption by 12 percent by 2020.

15% of all heating costs could be lost through an un-insulated loft, whilst a third of heat loss occurs through un-insulated walls according to the Energy Savings Trust. So before specifying your wood fuel heating system, you should look at any steps you can take to improve energy efficiency within your buildings. Having a well-insulated property is important in maximizing the benefits of your renewable energy system.

Energy efficiency should be the first consideration, as retrospective fitting of energy efficiency measures after the installation of a woodfuel boiler will result in your boiler being oversized and subsequent labouring of your equipment. The cost of your boiler will also be higher than necessary since it will no longer be required to run at full capacity.  Overall, insulation and other energy efficiency measures offer a lower per unit cost reduction to heating bills than that which can be achieved through the installation of renewable energy technologies.  When combined with the installation of wood fuel boilers, energy efficiency measures may reduce the overall cost of switching to woodfuel.

Support is available for businesses, households and public sector energy efficiency measures. The Carbon Trust and Energy Savings Trust can provide energy assessments and interest free loans for energy efficiency measures for households and businesses. The Central Energy Efficiency Fund provides support for public sector organisations.
