Similar in specification to the Twin Coil models our Triple Coil cylinders feature a total of three heat exchanger coils – two 1” (28mm) coils heating the upper section and a 22mm renewable coil at the bottom.
This flexibility means that, for example, the cylinder might be heated by a solar thermal system via the renewable coil, a wood pellet boiler supplying the primary coil and a back-up oil or gas boiler on the tertiary coil.

Because we use a thicker layer of high quality polyurethane insulation our cylinder range has amongst the lowest fully certified heat loss levels currently on the market, saving precious fuel and reducing carbon dioxide emissions.
Our 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 our 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.
Seamless welding, duplex stainless steel, efficient coil-in-coil design - The Warmflow triple coil vented cylinder is one of the top performing cylinders in the UK.

The Eco Direct is the Twin Coil equivalent for electric hot water installations. It features two immersion heaters intended for use in the same manner as those of a Direct cylinder.
