What is a biomass boiler?

Logs for use in a biomass boiler

There are now a lot of heating options available on the market. From conventional gas and oil boilers to biomass boilers. Biomass boilers are often less talked about than other heating systems, so this article aims to outline what a biomass boiler is and their benefits.

Simply put, biomass heating systems burn wood to generate heat. A biomass boiler is connected to a home’s heating system, in order to provide heat and hot water. A 12kW biomass boiler is usually the standard for residential properties, generating enough heat and hot water for a 4-bedroom house.


When deciding whether or not a biomass boiler is suitable for your property its important to take a few things into account:


Biomass boilers are far larger than conventional boilers, so your property will need to be thoroughly assessed to decide whether or not you have the space needed.

Planning permission

While needing planning permission for a new boiler is rare, you should always check before any work is carried out. All new wood heating systems are required to comply with building regulations.


There are three different types of wood used to fuel biomass boilers: chips, pellets, and logs. Chips are most commonly used when heating large buildings or groups of houses; logs can be a cheaper option than pellets but need to be put into the boiler by hand; pellets are easier to use, and can run automatically, much like a conventional boiler. The best option for you depends on the size of your house, as well as your budget.


There are three main benefits of biomass boilers:


One of the biggest draws of biomass boilers are their environmentally friendly credentials. The process of burning wood is considered sustainable, making biomass boilers a renewable energy source.


While biomass boilers can be more expensive than your conventional boiler, homeowners can make savings by having one installed. According to the Energy Saving Trust, having a wood fuelled biomass boiler installed in your home could save you close to £1000 pounds each year. This is due to the smaller CO2 emissions that biomass boilers produce.


The government is dedicated to reaching the UK’s targets for climate change, and as a result, there is a scheme in place which grants homeowners money to install environmentally friendly heating options. One of those options is a biomass boiler. All homeowners or private landlords in the UK are eligible under the Domestic Renewable Heat Incentive.
