Description
Resideo TX-25V Thermal Expansion Tank
The Resideo TX-25V is a 10.3-gallon thermal expansion tank engineered to protect closed-loop potable water and hydronic heating systems from the damaging effects of thermal expansion. As water is heated, it expands — and in a closed system, that expansion can cause dangerous pressure spikes that stress pipes, valves, and water heaters. The TX-25V absorbs this excess volume, maintaining safe system pressure and extending the life of your plumbing and heating equipment.
