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.

Fuel Types

Unlike heating oil, woodchips are a local and environmentally friendly fuel which is not subject to the same fluctuations seen in the fossil fuel market. Woodchip production provides opportunities to bring historically under-managed woodlands back into a management regime and provides opportunities for employment, making it a very good fuel both economically and ecologically.

Wood pellets provide opportunities for natural wood shavings and sawdust generated as a bi-product from the forest industry to be compacted and pelletised into a quality fuel for biomass heating systems. This fuel type has a high energy output and is easily delivered and stored.

Woodpelelts have a high energy output and are easily delivered and stored.

Logs are a natural and ecologically desirable fuel. They are considered CO2 neutral, sustainable and are not subject to the market fluctuations seen in the fossil fuel industry.
