Available from June 2009, Grant Ireland’s striking new collection of contemporary ‘Wave’ cylinders has created quite a ripple within the heating industry.
This comprehensive range includes upgraded twin-coil and new triple coil cylinders with sizes ranging between 200 and 400 litres.

Grant Twin Coil Options
The Twin Coil range of mains pressure hot water cylinders 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 Triple Coil Options
The Grant DuoWave Plus is a cylinder unlike any on the market at present. The model is a further development of the Twin Coil cylinder range and available in a 300 litre vented or unvented arrangement. Triple Coil 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.
Superior Quality and Design
These extremely efficient cylinders are unusual in their design, with every unit being manufactured from the highest specification 1mm thick duplex stainless steel. The casings are also injected with 40mm of CFC/HCFC free, fire retardant polyurethane foam. These innovative manufacturing processes achieve surprisingly low standing heat losses, ensuring outstanding efficiency and reliability. Grant cylinders are constructed with high efficiency internal coils using 22mm corrugated stainless steel tube, giving maximum heat transfer, high efficiency and quick recovery. Additionally featuring 22mm compression fittings, labeled and colour-coded tappings and a 25 year guarantee on the cylinder shell, this competitive range altogether offers exceptional quality, value for money, as well as peace of mind.
