Baxi 210i Indirect Unvented Hot Water Cylinder - 7798181
The Baxi 210i Indirect Unvented Cylinder is a high-performance 210 litre hot water cylinder designed to deliver strong mains-pressure hot water for busy domestic properties. Manufactured from durable high-grade duplex stainless steel, this cylinder offers excellent corrosion resistance, long-term reliability and efficient stored hot water performance.
Designed for use with compatible system and heat-only boilers, this indirect unvented cylinder uses a coil-in-coil heat exchanger for fast recovery times and efficient heat transfer from the boiler. Its internal expansion design removes the need for a separate external expansion vessel, helping save installation space and simplify the system layout.
