Gledhill PROIN300PPSP 300L Pro Indirect Pre-Plumbed System Plus Unvented Hot Water Cylinder

The Gledhill PROIN300PPSP is a 300 litre Pro Indirect Pre-Plumbed System Plus unvented hot water cylinder designed for fast, error-free installation in new-build and retrofit projects.

Built on the StainlessLite platform with pre-plumbed pipework and manifold for two heating zones, it delivers high-flow mains-pressure hot water when paired with a heat-only or system boiler. The 550 mm diameter and 1990 mm height suit standard plant rooms while the 50 mm insulation minimises standing heat loss.

Trade staff note the pre-plumbed configuration reduces on-site time and standardises installs across multiple dwellings.
