    Rated 5 out of 5 by from Reliable We bought this water heater to replace an older unit. Very happy that we increased the number of gallons as now we never run out of hot water! No rust or funny smell.

    Rated 4 out of 5 by from Good product We just had this water heater installed yesterday and I like this water heater a lot. This 75-gallon heater worked great for my 4 bedrooms and 3 baths house. The only reason it did not get a 5 star is that there were 2 cosmetic dents from either manufacture or the warehouse so, other than that it was perfect.
