Gledhill PLUHP210SL 210L Slimline Heat Pump Unvented Hot Water Cylinder

The Gledhill PLUHP210SL is a 210L slimline unvented stainless steel cylinder specifically engineered for heat pump applications, delivering mains-pressure domestic hot water. It utilises a high-efficiency multi-pass corrugated coil to maximise heat transfer from the lower flow temperatures typical of heat pumps.

Ideal for domestic installations where space is limited, the 475mm diameter fits narrow cupboards and older properties. Trade plumbers and installers benefit from the complete package including controls, expansion devices and a 3kW immersion for backup and legionella protection. Built to Gledhill’s proven StainlessLite Plus standards with high-density insulation.
