Biomass Boilers & Stoves

We’ve supplied domestic, commercial, agricultural, and industrial biomass boiler systems with a 100% success rate on all RHI applications we undertake.

Biomass Boilers are great for the environment as well as your pocket. With running costs lower than that of oil and Renewable Heat Incentive (RHI) eligibility, there has never been a better time to upgrade to this type of heating and hot water system for your home.


Biomass boilers are highly efficient which means you can benefit from a warmer house at a lower cost. A biomass boiler can convert up to 95% of the energy stored in wood to heat. Compare that to only 17% with an open fire and you can see the increased energy efficiency offered with a biomass boiler. 


Biomass technology is an economic alternative to oil, LPG and electricity for homes that are off the gas grid where the most expensive forms of fuel are the only options.



What are Biomass Boilers & Stoves?

A Biomass Boiler is simply a boiler that generates heat for central heating and hot water by burning organic matter. Commonly the fuel used in biomass boilers is wood pellets but the wood chip, split logs, and miscanthus are great alternatives.  

Biomass boilers come in a range of shapes and sizes so there is an option to suit all domestic and business needs. 

A biomass boiler will work in the same way as a conventional boiler by heating water and circulating water. This means they can be easily fitted to an existing system or installed as a brand-new heating system. 

For your peace of mind, we offer a servicing and maintenance package to keep your new biomass boiler running as it should. 

How do they work?

A biomass boiler works the same as a conventional heating system. They are fully programmable, and you can even control your heating and hot water at any time from an app on your phone. 

They also work the same way as a conventional boiler in the fact that they burn fuel to produce heat, they provide the same functions as fossil fuel systems.

The biomass boiler contains a heat exchanger in which the hot gases pass through and heat the water. The water is then pumped away from the boiler and circulated around the building. They can be linked to a thermal store to which the pipework of the boiler will be connected to which is in essence a large water tank that holds warm water which is ready to be circulated when there is demand. They can also be connected to an existing heating and hot water system, and even to underfloor heating systems.

What fuel do the stoves use?

There is a range of materials that class as biomass fuel such as grain, miscanthus, and chicken litter. Most biomass systems use log, wood pellet, and wood chip. 

Logs are cost-effective and are a good option for owners who have access to woodland. Logs are loaded manually into the biomass boiler so interaction from the owner is required. 

Wood chips are small pieces of wood that have been purposely processed as suitable sized fuel for boilers. They are automatically fed to the boiler. 

Wood pellets are made from compressed waste sawdust from sawmills. Unlike log systems, they can be connected to a bulk fuel store which means a pellet biomass boiler will be completely automated reducing the interaction required from the owner.   

We supply Klover Boilers, one of which is the popular Smart 120, which is a range cooker style boiler that also qualifies for the RHI payment. As a testament to how outstanding we believe the Klover stoves are, we fitted one in our own home and our office. You are more than welcome to visit, by arrangement, to help you decide which type is right for you and your home.

How much do they cost?

Biomass heating systems cost more than a fossil fuel boiler however, there are significant financial benefits to opting for biomass with the typical return on investment of around 20% over 20 years. 

They are economical to run and good for the environment compared to fossil fuel alternatives. 

The full price of a biomass installation depends on many contributory factors. A basic domestic installation will start at around £8K.

The Renewable Heat Incentive is available to help with the initial outlay for the installation of a biomass system.

Are Biomass Boilers cheaper to run?

Along with playing your part in reducing carbon emissions by replacing a fossil fuel boiler with a biomass boiler you could expect to see energy cost savings of anywhere between 30% up to 80% if you are replacing electric heating. 

What incentives are available?

Due to the government-initiated scheme, the Renewable Heat Incentive RHI has driven the increase in the use of renewable heat technologies in domestic homes. 

The scheme pays participants each quarter based on the calculated energy use for the property in that time, lasting 7 years. The payments are index-linked so the rate of the payments per kWh increase in line with the consumer price index. 

More recently the government has released the Green Homes Grants which could cover up to two-thirds of energy efficiency and low carbon heat improvements in your home. There are larger grants available for those who receive a qualifying benefit.
