With a central heating output of 25 kW and a hot water flow rate of 10.4 litres/min the Glow-worm Energy 25C combi boiler is a popular choice for use in smaller properties such as flats, apartments and houses with 1-2 bedrooms and 1 bathroom. As a new ErP compliant boiler, the 25C has been built to meet the new EU regulations concerning energy efficiency and as an A-rated boiler model you can rest assured you will be getting a high efficiency heating performance, something that can see utility bills benefit in the long run. The Energy 25C model features a super-efficient aluminium heat exchanger that is designed to last a lot longer than your typical copper or alloy heat exchangers.
