Description
Resideo XPS-090V Hydronic Expansion Tank Overview
The Resideo XPS-090V is a 44-gallon, pre-pressurized expansion tank engineered to absorb hot water expansion in closed-loop hydronic heating systems. With a robust steel shell and heavy-duty butyl diaphragm, this tank is built to deliver long-lasting, reliable performance in demanding residential and light commercial applications. Its 1-1/4″ connection makes it compatible with a wide range of hydronic piping configurations.
Key Features
- 44-gallon capacity — handles high-volume closed heating systems with ease
- 1-1/4″ connection for straightforward installation into standard hydronic piping
- Pre-pressurized at 12 PSI from the factory for immediate, out-of-the-box readiness
- Maximum operating pressure: 100 PSI — suitable for a wide range of system pressures

Why Choose the Resideo XPS-090V?
Expansion tanks are a critical component in any closed hydronic heating system. Without proper expansion control, thermal growth in system water can cause dangerous pressure surges, relief valve discharge, and premature wear on pumps, boilers, and fittings. The XPS-090V’s large 44-gallon capacity and pre-pressurized design make it an ideal solution for larger systems where volume fluctuations demand a high-capacity buffer. The factory 12 PSI pre-charge aligns with typical residential and light commercial system fill pressures, reducing setup time on the job.
