Biomass cost and funding

As stated previously, costs vary for biomass according to the technology used, the scale of the installation, the amount of pipework needed and any thermal storage required.

Unlike other renewable technologies it is necessary to budget for fuel over the lifetime of the project. However, biomass (wood chip in particular) is very competitive and is currently cheaper than fossil fuels as shown in the graph below.

Payback periods and savings

When considering payback for domestic installations, savings are best made in areas that are not connected to the gas network. This is because the cost of the biomass fuels is more competitive than oil and coal yet less so than that of natural gas as shown in the diagram below.

Savings are also high for properties with high heat loads. For instance, a large farmhouse that uses oil heating with a requirement of 75,000 kWh a year might pay back the cost of conversion to a wood chip or pellet boiler in four to eight years, based on current prices and getting a grant.

For smaller three bedroom properties with an annual demand of 25,000 kWh, the best current paybacks (five to nine years) are for log boilers when replacing electrical heating systems.

The graph below shows a comparison of fuel types. It starts with the lowest to the highest in the following order: wood chips, wood pellets, natural gas, heating oil, LPG (Bulk) and electricity.
