Thermal Expansion Tanks

Falcon Expansion tanks are designed to protect water heaters from damage caused by thermal expansion. This is a process where water expands as it heats up, creating extra pressure that can cause tanks to burst or leak. Installing a thermal expansion tank is a great way to increase the lifespan of your water heater and prevent costly repairs by helping regulate pressure within the water heater. The 16 gauge cold rolled steel tank used in the construction of these tanks is a robust solution that ensures longevity and durability. In addition, the 100% butyl diaphragm design delivers superior performance and ensures that the tank remains leak-free for the long run. The factory pre-charge of 40 psi ensures that the thermal expansion tank is ready to use straight out of the box. It is important to note that the tank should not be used over 80 psi as this can shorten its lifespan. To ensure correct usage, homeowners must install a pressure reducing valve that will prevent excessive pressure from damaging the tank.
