Gledhill PLUDR180SL 180L Slimline StainlessLite Plus Direct Unvented Hot Water Cylinder

The Gledhill PLUDR180SL is a duplex stainless steel unvented direct cylinder from the StainlessLite Plus Slimline range, designed specifically for properties with limited installation space. Its slim 475mm diameter allows fitting where standard 550mm cylinders will not, delivering high-flow mains-pressure hot water to showers and taps without a booster pump.

Suited to domestic households or small commercial settings, it is heated electrically via two 3kW Incoloy 825 immersions (on-peak and off-peak) and is compatible with photovoltaic panels. Trade installers and competent DIYers will appreciate the factory-fitted temperature and pressure relief valve, 50mm EnviroFoam insulation and 25-year warranty.
