Heatrae Sadia Electromax is the combination of an electric flow boiler along with a hot water storage cylinder and a pre-plumbed factory fitted circulating pump. It can offer wet central heating and a hot water supply, both at the same time if required, with only a mains electrical connection and cold water supply needed. The integral duplex stainless steel unvented cylinder has a 180 litre capacity, delivering mains pressure showering, fast filling baths and a balanced supply to multiple tap outlets. It is ideally designed for sealed systems, compact in size and effortlessly fits into a standard domestic airing cupboard. This model is the Underfloor Heating version.
