Biomass boilers

Ashwell Biomass offers a complete range of biomass boilers (8kW to 10MW+) for the domestic, commercial and industrial markets within the UK. We can supply and install boilers from some of the leading manufacturers, including KWB, D'Alessandro and Kalvis. We also manufacture our own range of high quality Greentec biomass boilers at our own premises in Leicester.


A wide range of accessories are also available to provide a one stop shop for a full installation.

Conversion kits

Ashwell Biomass also produces conversion kits for commercial and industrial coal fired boilers, enabling renewable biomass fuels to be introduced into any existing heating system, not just for new installations. The result is an improved efficiency in excess of 20% as well as lower carbon emissions.
