The Redring Powerstream unvented instantaneous water delivers instant hot water at point of use. This compact and unique design eliminates the need for centrally stored hot water cylinders saving on electricity usage and important space. This is the 12kW unit which is the highest rated single phase heater on the UK market. Water is supplied to either one or two outlets: Either two hand wash basins or one hand basin and a shower using the dedicated Redring Powerstream Mixer Accessory Kit.
