What is a Central Heating Expansion Tank Used For?
Central heating tanks are an essential component for most domestic systems, helping to maintain the correct pressure throughout the system. Expansion vessels work similarly to an overflow tank, allowing excess water or air to be stored as the system heats and cools. All boilers are already fitted with an expansion tank, but they may need replacing if you frequently experience pressure loss, leaving you without heating or hot water. Browse our full selection of central heating expansion tanks here and find high-quality replacement parts.
