Installation of biomass

Your system should be fitted by a HETAS accredited installer, and if you want to benefit from the Renewable Heat Incentive and RHPP the installer must also be MCS accredited.

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.

Requirements:

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:
    1. Part L of the Building Regulations, England
    2. Northern Ireland
    3. Section 3 of the Technical Handbooks, Scotland
  • 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:
    1. England
    2. Scotland
    3. Wales
    4. Northern Ireland

Installation time

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.

Installer

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.

FAQs

Is municipal solid waste (MSW) considered biomass?
No. Although MSW is burned by local governments in the U.S., Europe, and elsewhere to generate electric power and heat, it contains inorganic materials such as plastics and metals and therefore cannot properly be considered biomass.
How often do biomass systems need filling?
This would depend on how often the boiler is used and the heat demand. The hopper may need filling anywhere between every couple of days if the demand is high to once a week if it is just ticking over. Attaching the boiler to a fuel store means filling less often, and you can buy automatic (self-filling) systems with a hopper.
How much do wood pellets cost?
