Zilmet Potable Expansion Vessels

Unlike standard heating vessels, Zilmet’s potable range is designed with hygiene and durability at the forefront. Whether you are installing an unvented hot water cylinder or a high-pressure booster set, these vessels provide the necessary buffer to keep your plumbing safe and compliant.

The most critical feature of a Zilmet potable vessel is its internal construction. With WRAS approved (Water Regulations Advisory Scheme) ranges available, it means the materials used will not contaminate your drinking water.
