ScaleRX™ protects your water heater from limescale buildup and keeps it running efficiently. It requires no power supply, batteries, chemicals or filters. ScaleRX™ uses a patented turbulent galvanic polarization (TGP) electrode to disrupt the formation of limescale crystals on water heater elements. In side-by-side comparison testing, ScaleRX™ was four times more effective than the leading electronic scale device. ScaleRX™ is easy to install and maintenance free.
