Gledhill PLUIN180SL 180L Slimline Indirect Unvented Hot Water Cylinder

The Gledhill PLUIN180SL is a duplex stainless steel unvented indirect slimline cylinder from the StainlessLite Plus range, providing efficient mains-pressure hot water for domestic properties where space is limited.

Suitable for new installations or replacements in 2-4 bedroom homes with 1-2 bathrooms, it connects to a conventional boiler (sealed or open vented) and features a high-efficiency corrugated coil for rapid reheat times. The slim 475mm diameter fits tighter spaces than standard 550mm models while maintaining 183L capacity.

Built with automated welding, post-weld treatment and 50mm EnviroFoam insulation for low heat loss, it carries full WRAS approval and a 25-year warranty.
