The AMTROL EX-15 Expansion Tank is an essential safety component for residential closed-loop hydronic heating systems. Specifically engineered to manage thermal expansion, this diaphragm-type tank absorbs the increased water volume that occurs as boiler water heats up, preventing dangerous pressure spikes. By maintaining stable system pressure, it protects your boiler, pipes, and fittings from unnecessary stress and prevents the pressure relief valve from nuisance tripping. Constructed with a heavy-duty steel shell and a high-performance diaphragm, this expansion tank ensures long-term reliability and efficient system operation. It is a vital upgrade or replacement part for anyone looking to maintain a safe and functional home heating system.
