About

Biomass heating systems burn wood in the form of pellets, chips or logs to provide heating and hot water for the home. Modern biomass boilers are highly efficient, using advanced technology to get as much useful heat out of the fuel as possible. Biomass systems are particularly suitable for homes that are off the gas grid and especially where there is a local, sustainable source of wood fuel.

Is a biomass heating system suitable for your home or business?

A biomass heating system can usually be used with your existing hot water tank and radiators. At GrEnergy, we can assess your situation and discuss the options with you. Things to consider for your Biomass installation:

  • Government funding available. Make money on the energy you use, more details below.
  • Energy efficiency first. Improve the energy efficiency of your home by increasing insulation levels and tackling draughts.
  • Flues and ventilation. You will need a suitable flue to disperse the combustion gases, and a permanent vent to provide sufficient air for the appliance.
  • Space. You’ll need a dry and easily accessible space to store your wood fuel. Bear in mind that the appliance itself will often be larger than its gas or oil equivalent, so cannot be wall-mounted. You may also need a buffer vessel (a heated water reservoir for either heating or domestic hot water demands).
  • Loading the wood and maintenance. A biomass heating system relies on regular top-ups of fuel. Depending on the system you install, it can be fully automated or you may have to load the wood yourself. You’ll also need to remove any ash build up in the system.
  • Availability of a local supply. Find your nearest supplier here at www.woodfueldirectory.org. It is recommended that you purchase your fuel from a company registered on the Biomass Suppliers List. This will be one way of complying with the RHI biomass sustainability criteria when they come into force (expected in October 2014).
  • Regulations. Biomass heating systems do not require Planning Permission as Permitted Development in England, Wales, Scotland and Northern Ireland. However, if you live in a Conservation area, Listed Building or in a area of Outstanding Natural Beauty for example, you may need to check with your Local Authority Planning Office.

Government Support for a Biomass System

Domestic

Biomass heating systems are eligible for the Renewable Heat Incentive (RHI). The domestic RHI will pay for each unit (kilowatt hour) of renewable heat generated by your system based on the estimated heat demand indicated by your home’s Energy Performance Certificate (EPC). The tariff will be paid for 7 years.

Non-Domestic (Commercial)

The Non-Domestic RHI scheme is designed to encourage the take up of renewable heating in commercial, non-profit and community heating schemes. For biomass systems, eligible heat use is metered and a payment made by the Government based on the size of the boiler and the actual amount of heat used. The payments are made quarterly and continue for 20 years (at a lower rate than the domestic rate). The scheme is currently up and running, and although other renewable technologies are supported, by far the highest uptake has been for biomass systems, as the financial benefits are particularly attractive for this technology. Although described as a “non-domestic” scheme, it can apply to multiple domestic properties under the “community heating” heading. Two or more domestic properties qualify under this scheme providing they are heated by a common boiler, as long as they are separately council tax banded. The heat can be used for space or hot water heating, heating greenhouses (but not poly tunnels), indoor swimming pools, industrial processes requiring hot water and many other uses.
