Corrosion is the primary reason that water heater tanks fail, causing expensive repair or replacement work. A.O. Smith's Permaglas tank lining is the gold-standard in protecting against leaks and helps prevent corrosion.
As deposits of lime and other sediments accumulate inside the tank, you'll notice reduced energy efficiency and higher operating costs. A.O. Smith offers residential water heaters with DynaClean — featuring water jets that redirect the incoming cold water, creating turbulence in the tank, which helps reduce lime build-up.
A.O. Smith products are designed with professionals in mind. They include installer-friendly features that allow for flexibility for easy installation, as well as Honeywell gas valve, brass drain valve, and single-function anode rods that save time on repair and maintenance.
