5D Biomass

 Biomass is the fourth largest energy source in the world after oil, coal and gas. It involves the production of renewable energy using sustainably managed plant and wood fuels primarily in chip, log or pellet form. However, additional fuels such as miscanthus, sawdust, grain and even food waste can be used. 

The most important aspect of any Biomass system is the design which will ensure that hot water and heat are available to the client whenever they are needed. The quality of the fuel used is also very important with particular emphasis on a low moisture content (ideally 25%) and the ease with which it can be delivered to reduce ongoing fuel costs. Finally the choice of boiler must meet the requirements of the system and the client. With a variety of different boilers on the market, 5D Group will advise you on those that are the most efficient and cost effective for your needs.

5D Group chooses from a wide variety of biomass boilers ranging from fairly basic log and multi-fuel boilers to more sophisticated and automated wood chip and wood pellet boilers. The boiler range all use tried and tested technology and offer a range of features, efficiency and convenience that can equal or better the best fossil fuel fired systems. Timers, auto-ignition, automatic fuel feed, de-ashing and sophisticated building management systems all contribute to ensuring that using biomass as a primary heating fuel can be as straightforward as using fossil fuels.

Biomass is the logical renewable energy source where you presently use oil or LPG or are not on the gas grid. Biomass can be wood pellet, wood chip, logs, wheat or miscanthus or whatever can be burned as fuel. Biomass can be fully automated, by incorporating auto cleaning and de-ashing systems, for example, or auto ignition. Good fuel feeding mechanisms ensure that biomass heating systems are no more complicated than your existing heating installation. Advice from 5D Group professionals: "When designing a biomass system don't forget about simple aspects, like your fuel store; think about the location, so your supplier can deliver your fuel exactly where you need it."


  • We have no tie to a manufacturer, technology or fuel.
  • We offer truly independent and expert advice to tailor a package specifically for you.
  • We are experienced in designing bespoke boiler systems - we treat each system as a different project.
  • We are able to integrate biomass into any size project: domestic, commercial and district heating systems.
  • We work with other experts to provide unbiased advice on the best solution for your biomass heating requirements.
The Renewable Heating Incentive (RHI) is designed to provide financial support to encourage individuals, communities and businesses to switch from using fossil fuel for heating, to renewables such as wood fuel - biomass systems. The RHI was recently launched for commercial systems, with the domestic incentive expected to start early next year. The Renewable Heat Premium Payment scheme offers a lump sum grant towards the cost of installing a domestic system. 

The RHI also provides businesses with an additional financial benefit to promote the use of renewable fuels. Once the initial investment has been repaid, many businesses are likely to see a net income from using Biomass energy. A typical return on investment in the Commercial Market at present is around 15% - 18% and the RHI is expected to be available to the domestic market from 2014.

The RHI is a Government payment for each kilowatt hour of heat used, in addition to any saving available on fuel usage. It is metered and paid quarterly for most installations and  provides a 20 year Government backed income, linked to the Retail Price Index. It can provide a significant income over a 20 year period.

Modern biomass combustion systems are highly sophisticated, offering combustion efficiency and emission levels comparable with the best fossil fuel boilers. Biomass can be sourced locally within the UK so assisting the security of supply and UK sourced biomass can offer local business opportunities to support the rural economy. By establishing local networks of production and usage the financial and environmental costs of transport are minimised and the use of biomass provides an economic incentive to manage woodland which improves biodiversity.  Many biomass fuels generate lower levels of atmospheric pollutants, such as sulphur dioxide, which contributes to ‘acid rain’. 

There are a growing number of Woodchip and Wood Pellet suppliers available. We have detailed here some of the more local operators in the South West who would be happy to provide you with a quote.
