"Rheem Gas Water Heater does well"

4.0 rating
Somewhat Satisfied

My wife and I recently (6 months ago) decided to upgrade the water heater in our home given that the previous water heater was very old and inefficient. After some researching we decided on the Rheem Performance 40 gallon gas water heater. The model has done very well, it supplies ample hot water for us and our daughter. There have been instances where we all shower in succession where we will run out of hot water, but that is rare. Our gas bill per month has decreased, indicating that the heater is more efficient than our previous heater. I would like it to be a bit more efficient though. We have not had any issues yet that would require repair and it has had great reliability and performance. I would recommend this brand and model to a friend. I think if I were to buy a water heater again I would stick with the brand but see if there is anything that has improved efficiency over this model.

"This is an awesome unit!"

I have owned this water heater for 3 years. The one we had prior was extremely old and had been in our house prior to me and my wife buying it. It doesn't take very long for it to heat up water and is somewhat energy efficient. The only thing me and my wife do not like about it is the capacity. We wish it was a bit bigger but this is the biggest one we could get and the only one that would fit in our house without having to do a serious overhaul of the current storage place .


"Consistant and Reliable water temperature"

5.0 rating
Very Satisfied

I've had this water heater for over one year and couldn't be happier with its performance. The temperature is consistent throughout its use and provides a quick response when turning on the hot water. I haven't needed any repairs or encountered any problems since I've been using this specific model. I also take quick showers and live by myself so that may have some influence on my decision.

"Excellent and Economical Water Boiler"

5.0 rating
Very Satisfied

Our previous water heater, which came with the house when we bought it, recently died. It must have been in there for at least 25 years. We always ran into issues with not enough hot water, or with it taking to long make hot water. When it finally died we knew that it was sign to purchase a new one. We went to the nearest Home Depot about 3 months ago and purchased the Rheem 40 Gallon model. This was more than sufficient for our small family. Removal of the old water heater took more time than it did to install our new model. Installation was quick and painless and in short order we were taking hot showers again. In the short time that we've owned the unit, we've never run out of hot water, our energy bill has gone down slightly due to the more efficient design of the new unit and we're happy to say it was the best decision we have made. I'd recommend this unit to anybody looking for a new or replacement unit.

"An excellent water heater for a small family"

5.0 rating
Very Satisfied

We've owned this water heater since April of last year, so it's been just over a year now. It's a 40 gallon, two-element water heater. The box was small enough to fit in the back of our mini-van, and I wired it in to the electric box myself. The installation was very straightforward. I had it up and running in one afternoon. It's been a great unit for our family. There are three adults here and one child and we never run out of hot water. As soon as about a gallon is run from the unit, it begins reheating again, so the thermostat is very responsive. If you take too long of a shower after someone else or while someone is washing dishes, it might cool off a little, but so far no one has had to take a cold shower. At just over a year, it's still pretty new, so I don't know how long it will last, but so far so good. It hasn't required any maintenance. I would buy this unit again and I'd recommend this unit to anyone looking for a simple to install water heater that provides trouble-free operation.
