  • Since no two homes are the same, the ProLine Master family of electric water heaters offers a wide range of water heating solutions. These cutting-edge models bring commercial-grade design into residential applications. Like the gas models, ProLine Master electric products have increased anode protection with either larger or multiple CoreGard™ stainless steel core anodes depending on model. ProLine Master products are also outfitted with longer lasting, stainless steel upper and lower elements that are modeled after those used in our industry-leading commercial line.

    Efficiency & Performance You Can Count On

    An impressive blend of efficiency and reliability, the A. O. Smith’s ProLine residential water heaters are built with the same technology and care as our industry-leading commercial line. They’ve been thoroughly tested in our labs to ensure that they last, and that means peace of mind for you and your family.

    Industry-Leading Extended Warranty

    All A. O. Smith water heaters are backed by top-notch tank and parts warranties. ProLine Master offers extended 8-year warranty protection.

    Improved Tank Protection

    Larger commercial-grade stainless steel core anode rods that provide exceptional tank protection. Longer-lasting commercial grade stainless steel upper and lower elements.
