Stainless steel open-vented or unvented indirect triple-coil mains pressure hot water cylinders for combining solid fuel, biomass, gas, electric or oil-fired boilers and solar thermal systems.
The Grant DuoWave Plus is a further development of the DuoWave cylinder range and is available in a 300 litre model only. The cylinder is designed to combine different heating technologies within a single system by utilising up to three separate high performance heating coils and one 3kW immersion heater.
When installed as an open vented cylinder, it is possible to combine a solid fuel or wood burning appliance with an oil or gas boiler. An additional heat source, such as solar thermal can also be linked using the high performance coil, located at the bottom of the cylinder.
The unvented version is similar in design, but incorporates all of the additional controls necessary to use the unit in an unvented system installation. It enables up to three separately controlled heat sources to be linked together. This is particularly useful when combining traditional fossil fuel appliances like oil or gas boilers with renewable technologies like heat pumps, solar thermal or fully controlled wood pellet (biomass) boilers.
*If the DuoWave Plus is to be connected to a non-thermostatically controlled appliance (e.g. Solid fuel back boiler), the cylinder must be installed in an open-vented system to comply with current Building Regulations. Note: In an open-vented system, the T+P Valve would not operate in pressure mode, but may still operated on temperature, so it should be connected in the correct manner (see installation manual).
