  • Size
Size: 2.5 Gallon
I am a plumbing company owner in Cincinnati and would recommend this heater, easy install and quality is good. Only draw back is it's larger size. Takes alot of room under a sink.

  • Very nice and efficient.
Size: 4 Gallon
I actually now own two of these little heaters. I was so happy with the first one that I bought another for a sink in my shop. They are easy to install using readily available water supply lines. They can either sit on the floor or hung on a wall using a special hardware which is included. I damaged the heating element on the first one and that was difficult to replace, because the plastic heater shell does not come apart easily. The bottom of the heater should be redesigned to allow easier access to the heating element. Otherwise, a great, reliable product. ... show more

  • Much improved from older version
Size: 2.5 Gallon
I bought this same size water heater from Rheem almost 15 years ago and it worked great until it rusted out and leaked. Between the water and the rust stains the flooring underneath was ruined. This model has a plastic exterior and is a little bigger than the old one so it barely fit under my sink but I'm hoping it is insulated better. Also, the temperature control is much easier to use. ... show more

  • Great unit
Size: 4 Gallon
Installed this under my bathroom sink as a helper tank. My bathroom is so far from the hot water tank it takes forever to get hot water. Installed this under the sink so I never have to wait for hot water anymore. Plan to do this at my parents house to that have the same issue I did. Great product!
