Top 6 Best Water Heater Expansion Tank

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.

Accepts expanded water caused by thermal expansion. Returns water to the system when hot water is used. Prevents the relief valve from going off. Inline thermal expansion tank. Accepts expanded water caused by thermal expansion. Returns water to the system when hot water is used. Prevents dripping faucets, intermittent toilet fill and pressure relief valve discharge. Protects water heater, appliances and fixtures.

Designed to meet the requirements of, and are listed by the National Sanitation Foundation NSF under ANSINSF Std 62. The Butyl diaphragm has seamless construction and is designed to flex rather than stretch and crease like bladder tanks. The polypropylene liner for the water reservoir will not flake, chip, crack or peel and does not impart taste and odor to the water. Diaphragm, liner isolate water from contact with deep drawn steel domed shell - twice as strong as rolled steel shell of same thickness. A high gloss enamel finish protects tank from the elements. Pre-charged to 25psi please refer to product manual for proper pre-charge setting. Designed to meet the requirements of, and are listed by the National Sanitation Foundation NSF under ANSINSF Std 62.
