Resideo by Honeywell XPS-030V 14 Gallon Hydronic Expansion Tank with 1" FNPT Connection

The Resideo by Honeywell XPS-030V is a 14-gallon hydronic expansion tank designed for closed hot water heating and solar systems. Part of the commercial-grade XPS Series, this expansion tank features a durable butyl diaphragm design that effectively separates the air cushion from system water, preventing waterlogging and maintaining consistent system pressure.

Key Features:

• 14-gallon total volume with 11.3-gallon maximum acceptance capacity
• 1-inch internal FNPT (Female NPT) connection for secure installation
• Butyl/EPDM diaphragm construction—9 times more durable than natural rubber
• Pre-pressurized to 12 PSI for optimal system performance
• Maximum operating pressure of 100 PSI
• Maximum operating temperature of 240°F
• Compact design: 15-3/8" diameter x 23-7/8" height
• Steel and plastic construction for long-lasting reliability

This expansion tank absorbs thermal expansion in larger hydronic heating installations, maintaining proper system pressure while keeping fluids circulating efficiently. The clamped diaphragm design ensures reliable separation between air and water, extending tank life and reducing maintenance requirements. Ideal for commercial boiler systems, radiant heating applications, and closed-loop solar installations.
