Biomass fuels usually comes in the form of wood, straw and many other types of organic waste. Although all of these can be used to create energy, there are generally three main types of Biomass boilers that we install:

Wood pellet boilers – More suitable for domestic properties as the pellets are highly calorific and burn for longer and thus requires less regular ordering and maintenance, plus the storage space required for the pellets is minimal with most having an autofeed via a hopper.

Log burning boilers/stoves – Again for domestic properties, these have to be filled with wood by hand and require considerably more work. You will need a lot of logs to heat a whole house, and a lot of storage space, but they can be cheaper than pellets if you have a good local supply.

Wood chip boilers – a cheaper fuel generally used on a commercial scale where storage space isn’t an issue and there is plenty of space for large automatic feeding fuel hoppers.

Biomass fuel is considered a ‘carbon neutral’ and a renewable source of energy. Trees being grown for fuel will absorb as much CO₂ as those being burnt for heat will release.


With biomass you will be able to save between 30-50% on current oil or LPG heating costs. Excellent savings will still be achieved if the current system runs on gas.

In addition you could benefit from £1,000’s of pounds per year for the next 7 years from the Renewable Heat Incentive.

There are also long term savings to be enjoyed too as the costs of fossil fuels continues to rise, biomass fuel has not been subjected to the same pressures. Indeed specialists predict a decline in the cost of biomass fuel as demand increases through the awareness of this renewable energy.

And of course biomass is good for the environment with significant Carbon Dioxide savings of up to 15.4 tonnes a year!

This table shows how much you could save by installing pellet central heating in a typical four-bedroom detached house with basic insulation, taken from the Energy Savings Trust.

The domestic Renewable Heat Incentive (RHI) was designed by the Government to encourage households to switch to a greener, renewable method of generating heat. Although Biomass boilers required the burning of wood pellets or chips, it is still a very low carbon method of heating and therefore benefits from the RHI.
