Are you an environmental enthusiast or a business owner who is looking for a greener alternative to a traditional heating system? If so, why not consider switching to a biomass boiler?


As the world continues to grapple with the challenges of climate change and the need for sustainable energy solutions, biomass boilers have emerged as a remarkable technological development offering both environmental and economic advantages. At Ranheat, we design, install and manufacture an extensive range of wood waste management and biomass heating solutions. Our team of expert biomass engineers can help you find highly sustainable and reliable heating systems for leisure, commercial or industrial use.

What is a
Biomass Boiler?

Biomass boilers are innovative heating systems that harness the power of organic materials to produce heat and hot water. Unlike traditional boilers that run on fossil fuels, these heating systems utilise renewable biomass resources, making them a carbon-neutral alternative that significantly reduces the amount of greenhouse gas emissions.

By harnessing the inherent energy stored in biomass materials, biomass boilers offer a cleaner and more sustainable heating option and help reduce dependence on limited fossil fuels.

Similar to conventional boilers, a biomass boiler works by burning fuel to generate energy, which is then used to heat air and water. However, it is considerably larger in size, owing to the fact that it burns wood pellets rather than gas; the boiler needs to be bigger in order to hold a significant amount of fuel.

Biomass boilers use a wide range of materials as fuel, including grain, miscanthus and chicken litter. However, the majority of these systems primarily utilise three main types of fuel: logs, wood pellets and wood chips. Each fuel type offers distinctive advantages and options depending on the circumstances.

Logs are a popular choice for those who have access to abundant woodland resources as they can lead to significant fuel savings. These systems require the logs to be manually loaded into the boiler, thus necessitating regular interaction from the owner.

Meanwhile, wood pellets are produced from compressed sawdust, a byproduct of sawmills. When connected to a bulk fuel store, pellet biomass boiler systems can operate fully automated, eliminating the need for manual filling.

As the name implies, wood chips consist of small pieces of wood chipped to a suitable size for biomass boilers. Once in the fuel store, they are automatically fed into the boiler, similar to the operation of pellet systems.

Types of
Biomass Heating Systems

There are three types of biomass boiler you can use to heat your commercial establishment or industrial facility.

Low temperature hot water (LTHW)

Accounting for a vast majority of biomass boilers in the UK, LTHW systems are usually run at temperatures not exceeding 90°C. They are often utilised as replacements for fossil fuel boilers and to heat residential properties and commercial buildings, including offices, restaurants and hotels.

High temperature hot water (HTHW)

Compared to LTHW boilers, HTHW biomass boiler systems operate at higher export temperatures, usually around 120–280°C. As a result, they are more suitable for buildings that have a constant demand for high heat.

Steam biomass boilers

Similar to HTHW systems, steam biomass boilers run at high export temperatures and are used when there are extensive onsite process heat requirements, such as for chemical production, cooking and cleaning.

How Much Will a Biomass Boiler Cost?

The cost of a biomass boiler will vary depending on your specific requirements. Factors that can influence prices include boiler size and capacity, the complexity of the installation process, and any additional components or customisation options.

To determine the exact cost of installing a biomass boiler system, we would encourage you to consult a member of our team. We will assess your needs and evaluate your site conditions and then provide a bespoke quotation according to your specific circumstances.
