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.

Easy to install
Size: 2.5 Gallon
Work as designed. Per other customers temperature dial is a little finicky with actual temperature. I am happy with this product.

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.

Easy to install. Max water temp is lower than specified
Size: 2.5 Gallon
If you have a little plumbing talent it’s easy install. No leaks, and it heats quickly. My complaint is that the water doesn’t get as hot as I’d like, without the thermostat very high.

Perfect for small jobs.
Size: 2.5 Gallon
Installed in my daughters home where kitchen sink was on other side of house from a tankless hot water heater. Solved the issue of wasting gallons of water and never really getting hot water for dishes. This size is adequate for a diswashing IF you have a dishwasher for the main dish washing duty. She washes pots and pans, etc. Fairly quick recovery. EASY installation with a 110v plug directly into the wall plug that powers the dishwasher.
