The Greenstar Utility 32/50 range of condensing oil-fired boilers offers a selection of market-leading systems developed and produced by Worcester Bosch. The company pride themselves on their dedication to manufacturing high-quality systems which are made to last as well as maintaining high efficiency. This series of condensing boilers has an efficiency of around 93% which gives them an impressive A rating under the SEDBUK (Seasonal Efficiency of Domestic Boilers in the United Kingdom) guidelines. This energy-saving performance cuts down on wasted fuel which saves consumers on their energy bills by between 5 and 10%. It also minimises the emissions of harmful gaseous substances such as carbon dioxide, making these boilers particularly environmentally-friendly.
Greenstar Utility oil-fired boilers maintain these efficient performances by reusing and extracting heat energy from exhaust gases that would otherwise go to waste. The boilers effectively turn the waste product of exhausts into a complementary energy source. The series is also developed to be convenient to install and place in domestic settings, use and maintain. All systems are also extensively tested to ensure reliability, robustness and durability over long periods of time and use.
