Heating & Cooling Expansion Vessels
Heating and cooling expansion vessels are essential for maintaining safe and efficient operation in pressurised systems. By utilising the natural expansion and contraction of water as it heats and cools, these vessels prevent pressure spikes that could damage pipes, pumps, or other system components.
Expansion vessels come in a variety of sizes and designs to suit domestic, commercial, and industrial systems. They can be installed on hot water heating circuits, chilled water systems, or closed-loop cooling setups, helping to stabilise pressure and prolong the life of your system.
