Gledhill PLUHP180 180L StainlessLite Plus Heat Pump Unvented Cylinder

The Gledhill PLUHP180 is a purpose-designed 180 litre unvented stainless steel cylinder optimised for heat pump systems. It delivers mains-pressure domestic hot water using a high-efficiency corrugated coil that maximises heat transfer from the lower flow temperatures typical of air source and ground source heat pumps.

Suited to trade installers and larger domestic properties, the cylinder maintains all the proven features of the StainlessLite Plus range with the addition of a 3 kW Incoloy immersion heater for legionella control and emergency backup. High-density HCFC-free insulation and duplex stainless steel construction ensure long-term durability and low heat loss.
