The TankSaver™ *
GSW’s exclusive TankSaver™ innovation impedes corrosion by bridging the burn back area with stainless steel so that the metal is no longer exposed. Independent studies indicate that this simple but ingenious idea significantly extends tank life.

The Turbulator™ **
Premature failure is frequently caused by lime build up in the tank. The unique patented GSW Turbulator™ generates a powerful zone of turbulence in the bottom of the tank which keeps lime particles in suspension and allows them to be flushed out of the tank.

Double Glass on Key Seam™ ***
Studies show that many water heaters fail prematurely due to improper glass coverage on the main tank weld seam. All GSW water heaters, have a double coating of glass protection on this key wear area.
