Expansion Vessels

Expansion vessels or tanks and are designed to protect domestic hot water systems and closed water heating systems from high levels of pressure during fluid expansion or contraction. As the water heats up, the pressure can increase considerably, so they’re a vital component of these systems, allowing them to function safely and efficiently. It’s absolutely crucial that you choose the right one for your system.
