Questions & Answers

Difference between the two 50 gallon Marathons

I am comparing the two Marathon 50 gallon hot water heaters with the same Model# MR 50245. The cheaper version has wattage at 4500 and the more expensive is 240. I can see a difference, but what does that mean except for the difference in the electrical service for the electrician?
Asked by: George
If the other unit (not listed in your question) has a 5500 watt element then it would have a slightly faster recovery rate.

Customer Reviews

50-Gal. Tall 4500 Watt Lifetime Electric Water Heater is rated 4.5 out of 5 by 264.
Rated 2 out of 5 by from Hot Water High Electric I had this water heater installed in May 2017 after the previous 2 gas water heaters failed before they could make it to their warranty. The HVAC company I called sold me on this water heater - 10 year warranty on the tank, super insulated, high efficiency, the best on the market. I just about fell out of my chair when I got the electric bill a month after the install. I was anticipating some increase in the electricity but did not anticipate my electric consumption to DOUBLE! I was hoping the first month was a fluke (40 gallons of cold water to heat upon installation). But no, here it is a year later and month after month my electric bill is DOUBLE what it was before installing this water heater. There have been no changes to my household other than this water heater to cause the increase in my electric. Yes, I have hot water, but if I had the money to rip this thing out and start all over again, I would in a heartbeat.

Rated 1 out of 5 by from long life bought a marathon model no. MR75245 and the bottom heating element went out, DO YOU THINK I COULD FIND A REPLACEMENT NO,NO,NO the one I took out is a bend-over measuring 19 1/2 inch tip to flange, I do not know how many people I talked to at RHEEM but could never get the right part, they sent me a 13 inch long one, so if you go to buy one, better buy a couple of spare heating elements because after time you will not be able to get the right part

Rated 5 out of 5 by from best ever If you want the best, this is the one and only choice for you.

Rated 5 out of 5 by from Lifetime Warranty? I thought that my warranty was a Lifetime warranty. My email said 10 years.

Rated 5 out of 5 by from Given a choice, I'll never buy anything else ... I installed an 85g Marathon in my home 3 years ago and after a few months I was sold! I was gone for 10 days and my water heater was switched off and I came home to residual hot water still in the tank! I had switched from gas to electric and have never looked back. Last year I installed a 50g at my mountain cabin! Nothing but thrilled with it! I've yet to run out of hot water no matter how many showers are taken! I cannot say enough good about the Marathon water heater.

Rated 4 out of 5 by from great tank we purchased the W/H for the tank life and high energy rating. Although the Vacuum Relief Valve has failed and finding parts is very difficult.

Rated 5 out of 5 by from Non rusting leakproof tank. We own three condo units on floors 4, 6, and 8 that have Marathon rust proof tanks, to prevent water leakage below.

Rated 5 out of 5 by from Great Product I have owned my home for over ten years now, Marathon water heater was there when purchased. To say we have a high iron content is not enough as it will turn brown in under 20 minutes if not softened. I have no smell in the water and have yet to run out of hot water with taking 3 back to back to back showers every morning between myself, wife and daughter " Which uses way to much hot water".. I love it and would recommend to anyone, I have installed hundreds and hundreds of water heaters and have yet to replace a Marathon.
