Rated 4.4 out of 5 by 40 reviewers.
Rated 5.0 out of 5.0 by hot water I thought when I provided an unlimited supply of hot water my wife would forget about Steve. She didn't. She run off with Steve. I'll bet Steve doesn't have an unlimited supply of hot water. I hate Steve. I give it 5 stars because it works and was easy to install. February 27, 2015
Rated 5.0 out of 5.0 by Energy Efficient Choice, Life Time Warranty In our area, propane is now more expensive than electricity, so it made sense for us to now convert some of our household appliances from propane to electric versions. Top of the list was our on demand propane water heater. We replaced it with this 50 gl. Super Insulated Water Heater. There is tank type electric water heater which has a better efficiency rating, but it has a fan on top which makes noise while gathering heat from the air in the space to elevate the temp of tap water. I liked this tank for many reasons... first, it is light weight when empty, so I did the installation by myself. The inside tank and exterior are non-corrosive polymer materials... the inside tank being reinforced with spun glass (I viewed the manufacturer's production video). Traditional tank heaters will eventually corrode, even with the cathodic protection that must be periodically replaced. This unit should never require replacement due to corrosion inside or out. The original purchaser given a life time warranty... as long as you own your home. That's a winner for me! We are on whole house solar, so cutting down on all our energy use is key. This water heater has proven to be a smart move, as it remains at temp longer due to super insulation. I have to say that the unit we received doesn't appear like the one in the photo for this listing. It's much larger in diameter and shorter in appearance... I will post a photo of our unit as installed. If you have a tight water heater closet, you may want to carefully measure the diameter of the unit you are purchasing, as this is larger than others I've seen... This unit is more than adequate for a family of four and is definitely the right choice for us being on solar and wanting something that truly conserves our electrical use. I would highly recommend it if you can get over the sticker shock... Figure out if you benefit from converting from propane to electric. Compare what you pay for 27 kwh of electricity with what you currently pay for 1 gl of propane If you are solar powered, electricity is the clean choice anyway... This tank will out last YOU get one December 29, 2011
Rated 5.0 out of 5.0 by Very cost efficient and lifetime warranty for tank Plastic tank, no future worries for another tank leak -- lifetime warranty on tank. Very lightweight. Unfortunately, HD's 'preferred plumber' never responded -- but did find a local plumber on my own that did an outstanding job installing the HWH. March 1, 2015
Rated 5.0 out of 5.0 by Dependable hot water with no unpleasant odor We replaced a 6-year old HW heater with this Rheem Marathon because we were tired of cycling peroxide through the old tank every three weeks because if the reaction to the anode rod from our well water. The difference was instant and it has been nearly 6 months since we replaced the tank. Not only is it more efficient, it is shorter, so fits better in the space. The installation was quick and easy, and the expert installer helpful. We are extremely happy with the unit, and happy we paid extra for this high-quality product. December 11, 2014
Rated 4.0 out of 5.0 by No rust and increased insulation. Love the fact that the tank is all plastic so it won't rust out. I also like the additional insulation on the tank so less energy is used. For the 3 months I've had it, I am pleased. It was a bit more expensive to purchase, but considering I plan to live at this residence for quite some time, I'm hoping it will more than pay for itself in decreased energy consumption and replacement cost since I should not have to purchase another unit as long as I own my home.
