Why install a biomass boiler In your business?

For businesses with higher heat usage, biomass can lead to a significant annual saving. The cost of heat generated by logs, wood chips or wood pellets is lower than the cost of heat from oil, gas or electricity.

  • Reduce your energy bills and your carbon emissions
  • Protect against future gas and electricity price rises, as biomass prices are generally stable
  • Could qualify for payments under the Non-Domestic Renewable Heat Incentive [1]

What are biomass boilers?

Biomass boilers use the heat generated from burning wood pellets, wood chips or logs for heating and hot water.

They are a renewable and carbon neutral alternative to fossil-fuelled boilers.

They can also be a low-cost option for providing your business with its energy needs.

What’s biomass?

Biomass is derived from recently living organisms and is usually wood-based.

Why is biomass thought to be better than a fossil fuel?

Biomass systems typically use fast-growing, renewable wood.

When such wood is burnt it only releases as much carbon dioxide into the atmosphere as the tree absorbed when it was growing.

This means that it's regarded as carbon neutral.

The Non-Domestic Renewable Heat Incentive (RHI)

To meet UK's renewable energy targets, the government has introduced the Renewable Heat Incentive (RHI). If eligible, the Non-Domestic RHI offers subsidies, payable for 20 years, for the renewable energy that your business system produces [1]

Which businesses use biomass boilers?

A biomass boiler could be suitable for almost any business. Some examples include:

  • A business with high energy bills - especially if it's off the gas grid
  • Single or multiple-site businesses
  • Schools or university campuses
  • Care homes
  • Glasshouses

Case Studies

Biomass boilers FAQs



Do biomass boilers cause climate change?
A: This type of boiler is considered a carbon neutral option because the wood burnt only emits as much carbon dioxide as the tree absorbed when it was growing. Biomass fuel is sustainable because new trees are planted to replace those that are used. The cultivation, manufacture and transportation of the fuel does lead to carbon dioxide emissions. The effects of this can be minimised if the fuel is sourced locally. Emissions from biomass are much lower than those from fossil fuels.
How does a biomass boiler work?
A: Wood is tipped or blown from a lorry into a fuel hopper and the fuel is then fed automatically from the hopper into the boiler. The fuel feed and air injection rates are controlled to meet changing needs for heat and to make sure the boiler is burning as efficiently as possible. During the operation, hot flue gases flow through the heat exchanger. With good quality fuel, less than 1% of it is left as ash in the grate and flue gas clean-up system. This is removed automatically into the ash box.
Does it take a biomass boiler long to heat up?
A: No. Biomass boiler controls are fully automated and provide low-carbon heat at the touch of a button. The boilers have automatic ignition.
Will I need planning permission for a biomass system?

A: This will depend on individual circumstances, but you may need planning permission. This will be more likely if your premises are in a conservation area, or if it's a listed building.

Your local planning authority should be able to help you with any steps you need to take.

Also consider whether you need to contact:

  • Building control
  • Your insurer
  • The freehold owner - if you're a tenant or leaseholder, you'll need the freeholder's written permission
