Heating Expansion Vessels

Protect your heating system and maintain pressure stability with our high-quality expansion vessels. Essential for closed heating systems, these units absorb excess water pressure caused by thermal expansion, reducing strain on pipes, pumps, and valves.

We offer a range of sizes and types to suit combi, system, and unvented cylinder installations — all tested to meet UK safety and performance standards.
