    Why is the quality of fuel so important?

    RHI regulation specify that the biomass content for the fuel should be at least 90% and less than 10% contamination.


    Feeding your boiler with biomass that is lower than the specified requirement can:

    damage or reduce the performance of the installation, leading to downtime and costly repairs

    be a false economy, poor quality biomass has a lower calorific value which means more fuel is required

    release harmful emissions into the atmosphere, exceeding local air quality restrictions, damaging the environment


    It is the owners and operators responsibility to demonstrate that the fuel that is feeding an accredited boiler meets the RHI requirements or there is the risk of losing the financial incentive and permit.  

    The industry message is to adopt a proactive approach. You should act now and gain peace of mind that your investment is protected, whilst also taking environmental due care and responsibility
