Heating Expansion Vessels
Heating expansion vessels are a key part of any sealed heating system. As water heats up, it naturally expands. Without a vessel in place, that increase in pressure could damage boilers, pumps, or pipework. An expansion vessel safely absorbs the excessive pressure, keeping the system balanced and protected.
By reducing pressure spikes and stress on components, heating expansion vessels help extend the life of your equipment and keep heating systems working reliably day after day. Available in a range of sizes and specifications, they’re designed to suit everything from small domestic systems to larger commercial applications.
At Pumpify, you’ll find a range of heating expansion vessels from big-name brands such as Lowara, Zilmet, Reflex, and Flamco. In most cases, they're relatively small. You may even have one in your home or office already! We make it simple to choose the right one and keep your setup running as it should.
