    Rated 5 out of 5 by from Perfect size for my condo Bought this State Gas Water Heater to replace my old one that was installed in 2005. The old State WH lasted 18 years, and until it stopped working, I never had a problem with it during all of these years of ownership. State has great reviews and is one of the brands recommended--my philosophy-stay with a winner!

    Rated 5 out of 5 by from Plenty of hot water Installed 9 months ago by local professional plumber to replace original 25 year old unit that finally started leaking. The water seems hotter than the old one, even though set on same temp. So far, we are pleased with this model.

    Rated 5 out of 5 by from Great WH so far We've had this water heater for a couple months and it's been working great so far. Ran both showers, dishwasher, and washer and it was able to keep up. I'm hesitant to give it 5 stars until we've had it for awhile longer but it's doing what it's supposed to so I will anyway. As long as it lasts at least 15 years and keeps up with our demand that's all we care about.

    Rated 5 out of 5 by from Super fast heating and very quiet My old water was 15 years old and the ignitor finally went. I bought because my contractor and good friend recommended it and I able to take a hot shower in less than 2 hours of having it installed, and unless you are

    Rated 5 out of 5 by from Just received the brand new State Water Heater The product was highly recommended by a professional plumber in town. It was just installed about 1-hr before I wrote this review. Therefore, I haven't had at least 1-month's experience with the product. It looks very durable, neat, and seems it will last a long time without problems. Would I recommend the product? At this point in time, I would state that the professional plumber recommended the product and has installed quite a few of them without problems.
