What is Biomass?


What is a Biomass Boiler?

Well a Biomass Boiler, is basically a boiler that burns wood in the form of pellets. The boilers are exceptionally efficient, meaning a warmer house for less. The boilers come in various shapes and sizes, some with integral hoppers to pour the pellets into to feed the boiler when it is on, right up to systems that include a large automatic hopper, there’s a solution to fit most domestic or business needs.

The boilers work like any other central heating system, in that you can fully programme when you want heating on or off, when you need hot water. If the boiler is in a room there will also be ambient heat coming from the boiler when its running. This can be fully integrated to your heating and hot water system. Its simple! And our qualified fitters will take you through everything you need to know to get the best from your boiler. We also offer a servicing and maintenance package to keep it all running as it should.

We supply Klover Boilers, one of which is the popular Smart 120, which is the a range cooker style boiler that also qualifies for the RHI payment.

And as testament to how outstanding we believe the Klover stoves are, we one fitted 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.



There is a wide range of biomass boilers and stoves on the market. However, here at Bywhe we mainly install Klover‘s range of boilers as Ron and the team have many years working with the product and find it to be the very best in terms of quality, reliability and efficiency. Klover pellet stoves are made with care and attention using high specification materials and components; this quickly becomes apparent when you see one. Further to this Klover pellet boilers have typical efficiency levels of over 90%.

The Klover range includes:

  • The Smart 120 and 80 as well as providing hot water and heating also have the ability to cook food which don’t require high temperatures. These also look great in your home.
  • The Star 14 and Diva models are boiler stoves and have a more sleek design with a glass panel to see the flames. They provide heating and hot water and range in sizes depending on the size of the house. They don’t have the ability to be used for cooking. These and the smart range also provide heating to air which means they produce some heat to the room they are located in whereas other models provide it specifically to the radiators.
  • The pellet boilers 24 and 35 are highly efficient pellet boilers and are designed to be located in utility spaces to provide hot water and heating for the home. These do not provide heating to air.

Rob has a Klover 120 stove which provides his hot water and heating and can be used for some cooking. Ron has a Diva Mid boiler which provides heating and hot water. It also provides hot water and heating for the Bywhe Office.

What Is The Renewable Heat Incentive (RHI)?

The Renewable Heat Incentive (RHI) 

The RHI is paid to domestic customers by the Government to promote the use of renewable heat. As long as you meet the requirements installing a biomass boiler will mean you get payments every quarter for 7 years. In Spring 2017, these payments increased by approx. 60%.

To get an estimate of how much you may receive you can use this calculator Domestic Renewable Heat Incentive Payment Calculator. If you have an up to date Energy Performance Certificate (EPC) this will make it more accurate.

The supply, design and installation of the system is all sold to the customer at 5% VAT rather than the standard 20%.
