Biomass is biological material derived from living or recently living organisms. In the context of biomass for energy this is usually plant based material such as logs, woodchip or wood pellets.

Heating with biomass is considered to be carbon neutral given that the carbon dioxide (CO2) released when burning biomass material is equal to the CO2 absorbed during the growth of the biomass during photosynthesis.

Biomass also supports the management of historically under-managed woodlands by providing a market for the poorer quality timber to be sold into. This brings a wealth of benefits from improving the biodiversity of the woodland through to local employment. Utilising this material means that you can continue to stay warm whilst helping improve the environment.

What are Biomass Boilers?

Biomass boilers are designed to utilize biomass materials to generate heat for central heating and hot water systems in the same way that a standard gas or oil boiler would. They can also be connected to process drying equipment for the drying of bulk solids such as logs, woodchip, grain (etc).

Nexus Energy only utilize high-quality German and Austrian boilers from manufacturers including “Heizomat”, “Froling” and “ETA”. Our ranges support biomass boilers from 7kW right up to 1MW + and with over 20 years in the heating industry our specialist engineers have the skills and experience to design, install and maintain your biomass system ensuring that all regulations are complied with.



Robert Bloos built the first automatic discharger system for woodchips in 1982 with the idea of utilising wood from his own forest with the same comfort as he would fossil fuels. He originally intended the discharger system to only supply the boiler with woodchips for his own agricultural business, yet more and more people showed their enthusiasm for the “Heizomat” and there are now 200 employees working within their German Factory.

Heizomat has now been manufacturing boilers for over 30 years and with over 31,000 boilers in operation has a reputation founded on well-engineered, uncomplicated boiler systems that benefit from state of the art controls and web-based integration.
