Biomass Boilers

Biomass boilers are a simple but proven renewable heating technology that have numerous cost saving and environmental benefits.

Because biomass is generated from organic material it is recognised as an excellent renewable heat source and could qualify for the Renewable Heat Incentive (RHI).

As part of a portfolio of renewable technology, Anesco has extensive experience of supplying and installing biomass systems into business environments.


  • A greater thermal efficiency compared to older systems
  • An excellent renewable energy source
  • Better for the environment than fossil fuel
  • Can qualify for the Renewable Heat Incentive
Biomass boilers can qualify for the RHI


Thanks to a huge effort made by the team at Anesco which is managing the install, we have been able to continue in our long-term ambitions to help reduce our emissions while helping tenants with spiralling energy bills.

I would like to offer my thanks to all the team for a fantastic professional install. I have been the site manager at Glebe Primary School for a very long time and must say in 14 years this has been the best company I have had the pleasure to work with.

Biomass Boilers & Heating Systems

Connected to a heating and hot water system, a biomass solution typically comprises a boiler and control system, along with pipes, pumps and flues.

Biomass boilers are also used in process heating in the various industrial heat transfer techniques relating to areas such as drying, distilling and curing,

Depending on the application there are various types of biomass boiler available with varying degrees of functionality, from manual through to automatic systems that require minimum user maintenance.

The term biomass refers to the organic biological matter used in the boiler, which can be in the form of wood, waste organic material and straw; however, woodchip and pellets are the most common source of fuel used in a biomass boiler.

As with oil and liquefied petroleum gas (LPG) fuelled boilers, consideration should to be given to how and where the fuel will be stored. The biomass fuel store needs to be adjacent to the biomass boiler, be weathertight and have good road access.

A new Biomass boiler has a thermal efficiency greater than 90%, compared to a 20-year-old oil fired boiler which could have a thermal efficiency of around 75%.  Furthermore, biomass fuel is at least 10% cheaper than kerosene heating oil, which can result in a typical saving of between 30%-50% of your current heating bill.

Biomass boilers are best suited to an organisation, business or industrial environment that has a sizeable heating demand, year-round.  These environments could include nursing homes, hotels, hospitals, large commercial units, leisure facilities or poultry farms.

As a biomass installer to businesses across the UK, Anesco will design and deliver a solution based on the individual needs of your business.

Why Biomass?

Under the Climate Change Act,  the UK has committed to a 26% reduction in carbon emissions by 2020, and as biomass is a carbon neutral heat source it provides a great eco alternative to fossil fuel heating.

With the introduction of MEES (Minimum Energy Efficiency Standard) a biomass system could help a business or organisation improve its Energy Performance Certificate (EPC) rating by lowering the carbon emissions.

Finally, with ever changing energy prices, coupled with the drive for businesses to reduce their carbon footprint, biomass offers a highly effective solution.

The Renewable Heat Incentive (RHI)

The UK government introduced the Renewable Heat Incentive (RHI) in 2014 to encourage businesses and households to embrace renewable heating technology by providing financial support to owners.

Biomass is one of the renewable heat technologies that qualify for RHI support and under the scheme it is possible for businesses to receive quarterly cash payments, over a twenty-year period.
