AquaSystem expansion vessels are precision-engineered in Europe and WRAS-approved for use in UK closed heating systems — a preferred choice for heating engineers specifying reliable, long-life components.

Expansion vessels are an essential component of sealed central heating systems — they absorb the increased volume of water as it heats and expands, preventing pressure build-up that could damage boilers, radiators, and pipework.
