    Rated 5 out of 5 by from Hot water in 40 minutes This is a replacement for original to the construction but is the same manufacturer. I intended to request the same manufacturer but the plumber had suggested this one. The original heater lasted 16 years and I was just starting to see indication of a problem. Overall I was very pleased with this brand. I had hot water within 40 minutes of installation .

    Rated 5 out of 5 by from Seems to be well built I had a difficult install location in the attic, I chose this brand because they appear to be better quality than what you get at the big box stores, this heater was also 18” in diameter which was a big plus getting up through a 20” opening!

    Rated 5 out of 5 by from Tried and True This is our second "State" Electric Water Heater. We just replaced the first one after 19 years. This new State-Proline had good reviews and ratings, a near identical replacement in size with improvements in efficiency. Looking forward to another 19 years. Oh, the first one was still working fine but with a lot of summer visitor thought it was just time to update.

    Rated 5 out of 5 by from highly recommended This product was highly recommended by a plumbing supply company that most plumbers in my area purchase their water heaters from. These contractors specifically purchase State Proline Tank Water Heaters for their dependability & construction.

    Rated 5 out of 5 by from It’s a water heater!! What more can I say? My old water heater began leaking. I contacted Lowe’s companies because I have had them do installation sales for me in the past. Their contractor, ARS/RESCUE ROOTER was the contractor assigned to replace my old water heater. Great product. Only had it for less than a week, but so far, it’s doing exactly what it was purchased for.
