Biomass Boilers


Biomass is a natural material obtained from living or recently living plant life. Our main source of Biomass is from types of trees that can easily be processed into fuel. We obtain our heat from biomass using specially designed stoves and boilers that can be connected to our existing central heating and hot water systems.

Is a biomass boiler part of the RHI?

A log or pellet boiler falls under the governments renewable heat incentive (RHI) scheme. This is worked on a tariff basis and the government review the tariffs every quarter and are changed accordingly.

What are the different types of Biomass?

Biomass is found in the following types:

shutterstock_176221571Logs – Possibly the oldest form of fuel ever used. Specially designed Log boilers allow batches of seasoned logs to be burnt efficiently for long periods of time to supply your heating and hot water needs. Logs are easily sourced and relatively cheap to buy.

Pellets – Wood pellets are a product of waste wood in sawmills and other wood processing industries, as well as virgin timber. The wood is compacted to create these easy to handle pellets that are burned on pellet stoves and boilers. They are a very efficient and a very cost effective type of fuel. Pellets are supplied in either bags or from a blown bulk delivery.

Wood chip – Wood chip is timber that has been shredded in a chipper. It has a low calorific value but is extremely cheap to buy. Wood chip is best suited to commercial installations as it needs a huge amount of space to be stored.

Where is Biomass suitable?

Biomass is suitable for near enough any property, old or new. A log or pellet boiler is ideal for any system due to its high output temperatures. Unlike heat pumps, a biomass boiler can be set at exactly the same temperature as your current fossil fuelled system so you would never know the difference, except for the extra pounds in your bank account!

One slight downfall with a biomass system is that you must have some available space for both the boiler and the fuel. Just be aware that an average boiler footprint is usually around 1 square metre and a small fuel store would be around the same.BioWIN-plus_large

What type of boiler is best for me?

Pellet boilers are the most common type of installation due to there ease of use. Pellet boilers are relatively cost effective to buy and are most similar to your current fossil fuelled boilers.

Log boilers are most suited to people who have a good supply of locally sourced seasoned logs and have time to load their boiler each or every other day.

How much will a biomass boiler save me?

On average, changing from LPG or OIL to a pellet boiler, chip or log boiler will save you around 30% compared to your current fuel costs plus the large RHI payments for seven or 20 years.

Fuel Supply and Management

We have active links with BSL registered fuel manufacturers and distributors of EN Plus A1 pellets (the highest quality of pellets to comply with the RHI), and high quality wood chip suppliers. Fuel quality has a huge impact on the efficiency, reliability and lifespan of the boiler. We can compare the market for the best prices, and arrange for deliveries for when your hopper is running low. We can install a fuel level monitoring system, which will notify us when you are due a delivery, and arrange for a top-up before you run out.

The cost of this service depends on the output of your boiler and the size of the pellet storage unit, and can be spread out into small, manageable monthly payments.

Service and Maintenance 

We provide various care packages for biomass boilers which include major and minor services which are required annually. We also carry out one-off services, telephone support and call outs for errors nationwide. If you have an issue with your boiler, get in touch with us today and we can discuss how we can help you.
