The Heatrae Sadia Megaflo 400 Litre Indirect Unvented Hot Water Cylinder (45050570) is a high-capacity, mains-pressure hot water storage cylinder designed for large residential and light commercial applications. Manufactured from duplex stainless steel, it operates at up to 10 bar working pressure and delivers a reliable, high-flow hot water supply without the need for a cold water storage tank.

The Heatrae Sadia Megaflo 400 Litre Indirect Unvented Cylinder (45050570) is heated indirectly via an internal coil connected to a primary heating circuit - typically a boiler or heat pump. As an unvented system, it operates at mains pressure, eliminating the need for a cold water storage cistern and delivering balanced hot and cold water pressure throughout the property. Suitable for large homes, HMOs, and light commercial premises, where high hot water demand requires a reliable, mains-pressure supply from a single, low-maintenance storage system.
