Installation of biomass
You will need to discuss the specifications with your installer to ensure that you get a system that meets your needs, such as heating only or hot water, as well as the capacity and the type of fuel that suits you best.
You will need to consider the following:
- Fuel storage space – Wood is bulky and heavy, so you need a large dry space near to where your supplier can deliver it to ensure you don’t have to carry it too far.
- A flue or vent – The smoke will need to escape, so you need a flue or vent. An existing chimney can be fitted with a lined flue fairly cheaply.
- Building Regulations– You must conform to safety and building regulations, which is checked for you if you use a HETAS accredited installer. Typically the regulations will only prove a problem in more unusual homes. More information can be found at the following sites:
- Smokeless Zones – If you live in a smokeless zone then wood can only be burnt in certain exempted appliances. Find out if you live in a smokeless zone
- Planning Permission–If your flue will extend 1m or more above the height of your roof, or your home is in a Conservation Area or World Heritage Site and you plan to install a flue on the principal or side elevation, which will then be visible from a road, or your building is listed, you will need to speak to your local authority to get planning permission for your installation. You can find more information on our Planning Permission page. Find your local authority:
This will be very variable and dependent on the size and specifications of the system. If you already have a central heating system, a wood fuelled system should be compatible.
We will only put you in touch with installers that are MCS accredited: Always use an MCS accredited installer for your biomass fuelled heating system. Only MCS accredited installers are able to sign off installations that will comply with the government’s Renewable Heat Incentive and RHPP scheme.
- Are biomass systems automatically controlled?
- Then can be either partially or fully automated if desired, using a control system which allows you to regulate the temperature, fuel and running of the boiler. Check the manufacturer's specifications for specific details.
- Can you burn logs in a biomass boiler?
- Yes, many designs allow the burning of logs and in some models the burning of both logs and pellets.
- Can wood pellet systems be automatically fed?
- Some biomass systems can be automatically fed and most systems with this facility will have a range of hoppers and fuel stores that can either auger or vacuum feed the fuel into the system.
- How do I buy wood pellets?
- Wood pellets come in 10 - 15 kg bags or can be delivered loose per tonne. We have more details on how to find a suitable supplier on our Biomass pages.
- We are going to fit our biomass system ourselves. Would the RHPP grant still apply?
- You are only eligible for a Renewable Heat Premium Payment grant if your biomass system is installed by a registered installer.
