Customer Questions & Answers

Is this a plastic tank or not?

I asked a couple other questions about maintenance, and got good answers. But the answers that come back keep mentioning that this tank is not plastic. The premise of the other questions was that it was a plastic tank and should never rust, but will it ever fail. The maintenance part is answer (should be flushed). But the answers have been saying that it's actually a stainless steel tank, and shouldn't rust because it's stainless steel (not because it's plastic). The description of this tank says "Plastic tank wont rust; ideal in hard water applications Lightweight jacket and tank make it easier to install" Is it or is it not? Here is some more information to make sure that we're all talking about the same thing: This is a Marathon Model # MR50245. The current price on 12 November is over $1,000 on website: http://www.homedepot.com/p/Marathon-50-Gal-Tall-4500-Watt-Lifetime-Electric-Water-Heater-MR50245/205466186 Thanks! Dan

What is the hourly recovery rate to 100 F?

What is the hourly recovery rate to 100 F?
Asked by: Ilovehotwater
The recovery is calculated for a 90 degree rise which rates up to 21 gallon-per-hour. A 100 degree rise would not be much different and should not effect that rate by more than 1-2 gallons.

Customer Reviews

Marathon 50 Gal. Lifetime Warranty Electric Water Heater with Durable Design is rated 4.4 out of 5 by 29.
Rated 1 out of 5 by from Mine failed. I have been very proud of this heater since I purchased it in '98 or '99. Now in 2016 it has failed with water pouring out of it.. Tried contacting Marathon and got no response. I paid twice the price of a conventional water heater but got less than twice the life of it. I understand that an item can fail but by not even being able to get in to contact the company to get the warranty process started is not acceptable. Also 2 weeks to wait for replacement would not be acceptable. (No longer stocked locally) It looks like I will be forced to buy an off the shelf water heater to get hot water for my family till the warranty issue is resolved.

In June 2016, the unit began gushing water. It was replaced under warrantee, but installation exceeded the cost of the water heater. In mid November 2016 the new unit began leaking, first around the base of the relief valve, then from behind the lower door. Plumber says the unit will have to be replaced AGAIN, only 5 months after it was installed. While I'm sure Rheem will again replace it, I'm not sure I want to install another Marathon.

The water heater arrived with damaged lower element access cover for which I am still awaiting replacement. This most likely occurred during shipping and not packing. This is supposed to be an excellent water heater with a lifetime tank warranty for residential use. I guess I'll have to wait a while to assess its longevity and performance over time and is why I just rated it good and not excellent. The water heater is easy to install although, for my installation, I had to do some significant modifications to the plumbing system since I was disconnecting it from a combination hydronic boiler and domestic water heater and installing it in another location. I had some issues with newly installed unions leaking but that was in no way the fault of the water heater.

I've lived in my house for about 17 years and have gone through 4 regular hot water heaters. They make it very difficult to replace the anode. I'd have to detach the whole water heater, tip it on its side (since I didn't have clearance at the top), just to replace the anode. With the fiberglass Marathon water heater, I'll never have to worry about replacing anodes or developing leaks due to rust. I should have done this years ago.

We had one of these installed to solve the sulfur smell problem with the well water. We have not had any trouble with it. It is very efficient. We had electricity go out for a week once and the water inside was still lukewarm. The tank is plastic so pay special attention to the draining instructions!
