Rated 5 out of 5 by from Marathon 40 Gallon Electric Water This product has a wonderful 25 year warranty if you register it online. Yes it is a bit more expensive but when you look at the time you have warrantee it is certainly worth it. It is a clean slim look. I love it.

Rated 5 out of 5 by from Marathon 40 gallon hot water tank Love this hot water heater. Needed to buy a pressure release drain pipe as it is not included in the 40 gallon version. Otherwise, loving the hot water and energy savings.

Rated 5 out of 5 by from Not cheap but worth it. We purchased this for our cottage after having installed a larger unit at our home. We are extremely pleased with the performance and quality of the Rheem Marathons. While they are not cheap the lifetime warranty makes it worth it seeing as the water at the cottage can be problematic on conventional hot water heaters. Rheem warrants their product regardless of the water source.

Rated 5 out of 5 by from Looks good, ask me in 15 years. So far so good. Definitely a slick looking tank. Easy to move into place. The last tank I owned lasted 15 years before it started to sweat. I look forward to decades of use out of this one. Wonder what the change will be to the hydro bill. Came set at a face melting 54 C which is totally nuts. Turned it down to "half way" and it is still crazy hot.

Rated 4 out of 5 by from Good product Pay attention to US gallons vs imperial gallons when sizing tank. Impressive product, hopefully stands up to the test of time.

what are the advantages to the 3kwh tank over the 4.5kwh tanks?Do you save on your hydro bill to make up the cost of the 3kwh tank?

Asked by: Wendi
The 3kwh tank heat elements have less total heating capability. That doesn't mean it can't get the water as hot, just that the 4.5kwh tank will heat a larger volume of water faster. So if your house runs through multiple tanks of hot water in a row, the 4.5kwh tank will reheat a whole tank quicker. But don't forget that as hot water is being used, the new water refilling the water heater is being heated simultaneously. Depending on the price difference, unless you have a monsterous need for multiple tanks of hot water in a row, I wouldn't spend the extra money. I have 4 small kids at home and we're fine with the 3kwh tank.

My current hot water tank is close to my high efficiency furnace. How many feet would the electric Rheem Marathon 40 gallon have to be? Thank you!

Asked by: Claire
Thank you for asking, Claire. As long as your furnace isn't heating the surrounding area to the level as to cause damage to plastic, the clearances in your Use and Care Manual, which can be downloaded on this page, should be sufficient. If you have any further questions, please contact us at 1-866-279-4566. Thank you and have a great day.
