More Info

Designed for use in closed, potable hot water systems, Therm-X-Span® accepts expanded water as system temperature rises. This hot water is returned to the system when demand occurs. A thermal expansion tank, like Therm-X-Span®, is essential in a closed system to protect your water heater.
