Gledhill PLUIN120SL 120L Slimline Indirect Unvented Hot Water Cylinder

The Gledhill PLUIN120SL is a StainlessLite Plus Slimline indirect unvented hot water cylinder with a nominal 120 litre capacity, ideal for properties with limited space where standard 550 mm diameter cylinders will not fit.

Manufactured from duplex stainless steel with automated welding and post-weld treatments, it provides durable, corrosion-resistant performance backed by a 25-year warranty. The high-efficiency corrugated coil maximises heat transfer from a conventional boiler, while the 3 kW Incoloy immersion heater offers emergency back-up heating.
