Rated 3.5 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by Hot water It was easy to install just wrap and tape saves money April 14, 2016
Rated 4.0 out of 5.0 by Very good This wrap is the way to go. The extra thermal protection should help say me some money. It was easy to figure out how to install. The only that would have made it better was if the wrap had some form of a cover to the top of the tank. February 25, 2014
Rated 3.0 out of 5.0 by Online description is NOT accurate; product / tape OK Package says "Acts like R19 Value*" in font that is 1/4 inch high, top center of packaging. Package says " 3.5 R Value" lower down in smaller font. I don't understand the physics of this heat transer equality -- possibly it's the New Math. The ONLINE description states this would cover a 60-gallon water heater, which I would strongly dispute. The ACTUAL PACKAGE does not make this claim, merely has the dimensions of the product adverstised on the package. I own a 40-gallon water heater, and used every square inch of this product to barely cover it. Some advice about cutting it follows. The top of my water heater is 75 inches from the floor, so I made the first cut into the product about 75 inches from the end, making a very long rectangle. This section was taped to the water heater using the supplied tape. The remnant piece was then taped over the exposed area, using the supplied tape. The tape was fine, separated from the backing okay, and had good adhesion to the product. I did not have any left to cover the top. It took me about 20 minutes to install. As the majority of the surface area is the SIDE of the water heater, and not the TOP, I judged the water heater was sufficiently covered. The product itself seems fine, but the advertising of it's capability (R-value and what water heaters it would fit) definitely needs improvement to gain the confidence of the customer. Bottom line: it worked fine for me, but I was annoyed by the inaccuracy of the advertised features. October 29, 2012
Rated 5.0 out of 5.0 by Saving me a lot of money I have a water heater in the attic of a cottage I bought in the fall. The attic is cold as can be so by wrapping the water heater I have greatly reduced the amount of heat loss. Should protect it from freezing too as we turn it way down when we leave. January 5, 2016
Rated 4.0 out of 5.0 by Good water heater blanket The blanket was good quality and pretty easy to install. The only recommendation is the sealing tape be a little wider. January 19, 2016
Rated 4.0 out of 5.0 by trying it for a different problem I have a flotek tank for my well that I had to replace because constant condensation caused the outside of the tank to start to rust and corrode. Didn't want to wait for a rupture (which the bladder might or might not contain.) So far it has been effective. Anyone else have experience with this use? July 21, 2015
Rated 3.0 out of 5.0 by Too small I bought this for our new water heater. I just installed a 50 gallon unit. This blanket is about 20 inches too short for the circumference. I ended up having to piece it together. This was the only WH blanket my closest HD had, otherwise I would return it. I even asked the guy working the isle if it would fit a 50 gallon tank and he said "yes". Perhaps HD should post a sign at this bin stating to measure your tank first. Advice: measure the circumference of your WH before you buy this. February 28, 2015
Rated 2.0 out of 5.0 by What I learned when I got home. When you replace a water heater you usually do it in a rush. So the value of the blanket, I don't know. The quality was OK. I didn't shop around on the price. It only took a few minutes to install. The aluminun tape that came with the blanket would not seperate from the paper backing. I had to use my own. The blanket was about 12" short in heigth from covering the 59" tall 50 gal.water heater. I had to use part of my old blanket to finnish. Like I said I was in a rush. I didn't stand there and read the complete print on the bag. My fault I assumed a water heater blanket would cover a water heater. February 21, 2012
