How to Recharge an Expansion Tank on a Hot Water Boiler

Feb 18, 2021 · Note: An expansion tank is not found in steam boiler systems, which create heat by circulating hot vapor rather than hot water through the pipes and radiators. Steam boilers are simpler systems that lack several components found in hot water boiler systems—such as the circulating pump, expansion tank, and regulators for water pressure and temperature.
