It reduces the stress on your hot water system and its various components including pipes, fittings, fixtures, and even your appliances. A thermal expansion tank may be also required to meet your local plumbing codes. If the water heater is installed in a closed water supply system, such as the one having a back-flow preventer in the cold-water supply, provisions should be made to control thermal expansion. DO NOT operate the water heater in a closed system without provisions for controlling thermal expansion. A plumbing professional can assess your specific system and determine during installation how best to control thermal expansion. Need a plumbing pro?
