    Rated 5 out of 5 by from HIghly Recommended by the contractor I had this unit installed last month and to-date it has serviced me well. In talking with the contractor, he highly recommended this unit even though my last State Water Heater was less than 8 years old when it failed. I have been assured that this is a self cleaning water heater and that it will last longer than my last one.

    Rated 5 out of 5 by from A thoughtful blend of digital and analog features I bought this recently to replace a failing old unit. My chosen installer recommended State brand as a good value among water heater makers so we took his suggestion. It seems to be an excellent piece, fitting into its space nicely despite its capacity, and the locations of its various controls seem well thought-out. The main control panel was nicely configured, and the various fittings and brass drain valve looked HQ. We anticipate many years of service from this nicely made unit.
