A frequently encountered problem with biomass boiler installations to date is the low seasonal efficiency of biomass systems, with many users reporting values of as little as 50%. Recent work undertaken in the UK has identified oversized boilers, undersized buffer vessels and inadequate boiler control systems as commonly found, preventable reasons for low system efficiency.
