Triple Coil Unvented
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.
