 Works well, R-value doubtful, wear gloves Jan 19, 2009
By Joe Airaudi
I got this product through Amazon because my local Home Depots don't sell them here in Austin. The product is just as described, it's basically fiberglass insulation with vinyl on either side. It is NOT sealed together, the way a down blanket is, it's more of a loose sandwich. It's easy to cut with sharp scissors, and you'll need to cut no matter what size water heater you have. Couple of things to note:
- I chose this model because it had the highest R-value (R10) in the description of any blanket/jacket I'd seen. The R-value was mysteriously missing from the product packaging, so now I doubt it was that high. You'd think they would capitalize on being 30% more efficient than the next model..
- I thought, since there is no warning to the contrary, that this was the kind of fiberglass you can handle with your bare hands without getting itchy. It's not, so wear gloves
For the money, I say get one, it can't hurt. Even though my water heater was cool to the touch while on, I can tell it's getting toasty under the blanket.

 Great product! Feb 08, 2008
By John Ehr
Works great on a 50 gallon tank...installed in last then 15 minutes! Not problem and easy to install. I did 2 of them in about 20 minutes. All you need is a pair of scissors.

 Don't buy it! Jan 30, 2009
By Ashish Shah
"Damodar"
I purchased this product based on other reviews. Well, this 75" blanket doesn't fit on my 50 gallon heater. I thought I was smart to measure the tank's circumference before ordering it, but I forgot one thing.
The circumference of the tank is 75", and so I thought it would be a perfect fit. Well, it turns-out that the blanket is 3.5" thick and so I forgot to compensate that the blanket's thickness will reduce the overall length as I wrap it around the heater. So now it's 1 foot short and I can't close both of the ends.
Besides looking ugly, it wouldn't be effective in its job to save energy. Now I will have to go look for an insulation piece 1 foot x 4 feet long from Home Depot to cover the silly opening.
It's funny that they're advertising this product for 60 gallons when it doesn't wrap my 50-gallon tank that has 75" circumference. I suggest you measure your tank first and then add at least 12" on top of it to get a total blanket length you need. Good luck!

Great value Jan 31, 2010
By SWLibrarian
We noticed an immediate difference in the efficiency of our hot water delivery. One water heater is in the garage and the other in the attic, but both deliver a much better, more consistently heated water supply. This is the most cost effective energy saving project we have ever completed.

 Good price, below average insulation. Jan 09, 2011
By Jan
CONS
- as other reviews this is too small for our boiler, but since our boiler is in the corner right at the two walls, I would not able to wrap it around the whole boiler anyways
- be ready for TONS and TONS of fiberglass dust after you are done everywhere in your garage - close car windows, doors to your house... (make sure to wear special clothes, respiratory mask, hat, glasses and gloves) - not exaggerating - you can argue that we are married with fiberglass these days - true - but even after adding blow-in (AttiCat) insulation to the attic it was not so messy job...
- more tape should be provided, used FlexFix from Nashua to fill the missing feets/meeters of tape needed
PROS
- after applying the insulated part is about 8F (4C) colder than the uninsulated part - so it really works (reason for 3 stars)
OTHER THOUGHTS
- let you wife know what you are up to so she does not feel surprised seing you hugging the boiler in the garage :) :) :)
Have fun!
