What are biomass boilers?

Biomass refers to a wood fuelled heating system that burns quick growing wood pellets, chips or logs to power central heating and hot water boilers. Biomass boilers are a renewable and carbon neutral alternative to fossil fuelled boilers.

What are the benefits of using a biomass boiler?

  • Fuelled by renewable, wood based materials
  • Carbon neutral
  • Typically lower fuel cost
  • Can provide long term savings, especially for businesses that are off grid


Fuel savings

Biomass boilers use the heat generated from burning wood pellets, wood chips or logs for heating and hot water. They can deliver substantial fuel cost savings, and are typically the lowest cost solution for carbon savings.

By 2020, 15% of all energy generated in the UK should be from renewable sources. To meet this target, the UK Government has introduced the Renewable Heat Incentive (RHI). Subject to detailed scheme rules. If eligible, RHI offers subsidies, payable for 20 years, for the amount of clean, green renewable heat that your business system produces.

Who are biomass boilers for?

Biomass boilers can be suitable for a wide range of businesses, including:

  • Businesses with high energy bills, especially if off the gas grid
  • Single or multiple site businesses
  • Schools or university campuses
  • Care homes
  • Glasshouses

Frequently asked questions

Do biomass boilers cause climate change?

When wood’s burnt in the boilers, it only releases as much carbon dioxide into the atmosphere as the tree absorbed when it was growing. A mature tree can take 80-100 years to grow. Unlike fossil fuels, a large amount of the carbon dioxide was collected in the last 100 years rather than millions of years ago. This means it has more of an effect on the current environment we live in.

How do biomass boilers work?

  • Wood fuel is tipped or blown from a lorry into a fuel hopper
  • 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 it can
  • Hot flue gases flow through the heat exchanger
  • With good quality fuel, less than 1% ash is produced in the grate and flue gas clean-up system


Does it take long for a biomass boiler to heat up?

No. Biomass boiler controls are fully automated and provide low-carbon heat at the touch of a button. The boilers also have automatic ignition.

Will I need planning permission to install a biomass system?

You may need planning permission if your premise is located in a conservation area or is a listed building. You may also need approval from Building Control or from your insurer. If you’re a tenant or leasehold owner, you’ll need the freehold owner’s written permission. If you have any concerns, your local planning authority should be able to help you.
