The ideal choice of mains pressure hot water cylinders

The cylinder range from Warmflow has been designed to satisfy the hot water needs of even the most demanding consumer. We have focussed our attention on ensuring the largest hot water volumes, shortest heat up times and lowest possible heat losses are achieved throughout our range of KIWA approved unvented cylinders. From the large coil-in-coil heat exchangers to the high performance foam insulation, no effort has been spared in developing a market leading hot water cylinder.

Because our cylinders work at mains pressure, they provide outstanding hot water flow rates, far exceeding those experienced with a combi boiler or traditional vented cylinder. As a result, baths fill quickly and showers are invigorating. And, because we supply an inlet control group with a balanced cold water connection, all the hot and cold taps in the house operate at the same pressure, so blending valves work at their best to ensure consistent comfortable hot water temperatures.

Environmental Investment

Because we 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.
