Warmflow Hot Water Cylinders

Warmflow use a thicker layer of high quality polyurethane insulation in their cylinder range producing amongst the lowest fully certified heat loss levels currently on the market, saving precious fuel and reducing carbon dioxide emissions.

Warmflow insulation is also CFC/HCFC-free, has a zero Ozone Depletion Potential (ODP) and a Global Warming Potential of only 2.

Due to the large surface areas of Warmflow coil-in-coil heat exchangers it is also possible for a condensing boiler to work in condensing mode for longer, and cycle less frequently when heating the hot water, thereby helping to further reduce fuel use and emissions.
