Grant Unvented Cylinders (Direct & Indirect)

This comprehensive range includes new MonoWave single coil, upgraded DuoWave twin-coil and new DuoWave Plus triple coil cylinders made up of 26 different WRAS (Water Regulations Advisory Scheme) approved direct and indirect variants, with sizes ranging between 90 and 400 litres.

Grant Duowave Indirect Twin Coil Cylinders The DuoWave range of mains pressure hot water cylinders share the same high performance characteristics as the MonoWave series, but were developed to meet the growing demand for systems that combine a renewable heat source with a standard oil, gas or electric boiler. They are particularly suitable for use with solar hot water systems like Grant Solar Thermal. When correctly matched and installed this arrangement can significantly reduce the dependence on traditional fossil fuels resulting in lower energy bills.

Grant Duowave Direct Cylinders The DuoWave range of mains pressure hot water cylinders share the same high performance characteristics as the MonoWave series, but were developed to meet the growing demand for systems that combine a renewable heat source with a standard oil, gas or electric boiler. They are particularly suitable for use with solar hot water systems like Grant Solar Thermal. When correctly matched and installed this arrangement can significantly reduce the dependence on traditional fossil fuels resulting in lower energy bills.

Grant Duo Plus Triple Coil Cylinders The Grant DuoWave Plus is a cylinder unlike any on the market at present. The model is a further development of the DuoWave cylinder range and available in a 300 litre vented or unvented arrangement. DuoWave Plus cylinders are designed to combine different heating technologies within a single system by utilising up to three separate high performance heating coils and two 3kW immersion heaters. When installed as a vented cylinder, it is possible to combine a solid fuel or wood burning appliance with an oil or gas boiler, alongside solar thermal.
