Top 8 Best Expansion Tank For Boiler

This non-portable water expansion tank is for closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief sett of the relief valve. The carbon steel tank is pre-charged at 12 psi, has a 4.5 gallon volume, and features a durable expansion membrane preventing minimizes loss of the air change and ensures long and trouble-free life for the system. Made of carbon steel with epoxy finish, mounts to supply piping, with 12 inch MNPT system connection and .302-32 inch charging valve connection for on-site charging of the tank. Maximum pressure 60 psi and can be used in residential or commercial hydronic heating systems. Use in tandem with your hot water heater to absorb increased water volume ensuring long and trouble-free life for the system.
