   Thermal Expansion

Protect your water heater from Thermal Expansion 
Water expands in volume as its temperature rises.  The extra volume caused by thermal expansion must go somewhere.  A thermal expansion tank added to your home water system offered the solution to this dilemma.

The temperature & pressure release valves on water heaters offer some release but should not be your only line of defense.  A thermal expansion tank provides increased safety and protection.
