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 be seen in 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. The innovatively designed heat exchanger is extremely quiet and emits little sound during operation. The 25C boiler model is nice and compact too so can fit in most typical kitchen cupboard spaces, helping to free up room in the home by hiding the boiler away out of sight.
