For over forty years, Grant has developed some of the most efficient oil-fired boilers in the UK. A new condensing boiler from Grant has significantly improved efficiencies and performances compared to older oil-fired appliances which can operate with energy efficiency levels as low as 65%. By choosing a Grant boiler, which can achieve energy efficiencies of up to 94.5%, homeowners can lower their fuel usage, reduce their fuel bills and lessen their greenhouse gas emissions.
