Gledhill PLTIN210 210L Platinum Indirect Internal Expansion Unvented Hot Water Cylinder

The Gledhill Platinum PLTIN210 is a 210-litre indirect unvented hot water cylinder with internal expansion, designed for use with gas or oil boilers in sealed or open-vented systems. Manufactured from high-specification duplex stainless steel, it provides efficient mains-pressure hot water for modern UK homes and is suitable for both new installations and replacements.

Trade and professional installers benefit from the internal baffle and air pocket that eliminate the need for an external expansion vessel, simplifying installation in space-restricted locations. The corrugated StainlessLite Supercoil delivers faster recovery times than plain coils, while high-density HCFC-free Envirofoam insulation minimises heat loss.
