How to Recharge an Expansion Tank on a Hot Water Boiler

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.

The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi. The pressure the system is designed to operate at is usually 12- to 25-psi for a two-story house, and 18- to 25-psi for a three-story house. The operating high temperature should not be over 200 F., but 180 F. is the normal maximum design
