The Calefactio expansion tank is a critical component for residential hydronic heating systems, designed to manage the thermal expansion of water as it heats up within a closed-loop boiler. This diaphragm-style tank effectively absorbs excess pressure, protecting your heating system's pipes, valves, and boiler from stress and potential damage. By maintaining consistent system pressure, it helps prevent the pressure relief valve from tripping and ensures a more efficient, quieter heating cycle. Built for durability and long-term reliability, this tank is a vital replacement part for maintaining residential HVAC performance and extending the life of your boiler equipment.
