Expansion tanks help to regulate the pressure in your boiler room and ensure that your closed system water heating stays safe. When pressures build up too high in a water heater, internal parts may fail which could lead to the potential release of toxic gases or could rupture your hot water heating tank which could void the manufacturer’s warranty. An expansion tank regulates the pressure by giving air and gasses somewhere to go when heat is built up.
