Grant has taken their already popular Solar Thermal package another step further, with the launch of a competitively priced, high quality, stainless steel, unvented, twin-coil cylinder range.
Grant DuoWave Cylinders are suitable for use with solar thermal installations and applications where a secondary heat source is being utilised. Available in 200, 250, 300 and 400 litres, the cylinders are ideal to provide hot water solutions for many types of domestic and small commercial properties and at only 580mm in diameter, they are narrow enough to be sited in standard airing cupboards. All models are manufactured from high quality, corrosion resistant 316 stainless steel, ensuring a long life expectancy. Internal coils are constructed from 22mm diameter stainless steel, giving high efficiency as well as quick recovery. The use of CFC free, fire retardant polyurethane foam as insulation, keeps heat loss to a minimum. Maintenance is minimal, as the cylinders are all fully flooded. Grant also supplies an additional vessel with each cylinder, to take expansion and contraction of the water within.
With a two-year guarantee on all electrical and mechanical components supplied and a 25-year guarantee on the stainless steel cylinder shell, the new DuoWave cylinders offer exceptional quality, value for money, as well as peace of mind.
