Expansion Vessels & Unvented Kits
Expansion Vessels are key components in Unvented water systems, ensuring that pressure is managed and steady through heating or cooling water tanks. As water heats up, it expands, raising pressure inside the system. The expansion vessel absorbs this extra pressure using a flexible diaphragm that separates water from compressed air, helping to prevent damage to pipes, boilers, and valves while keeping everything running smoothly and safely.
