Customer Questions & Answers

What's the r rating on the water heater blankets?

Asked by: janb
So this is very confusing. The Frost King SP57/11C comes in BOTH R=11 and R=10 varieties. Mind blowing. Same model number SP57/11C, different R-value. If you search online you can find different versions of the packages. The R=11 variety is 3.5 inches thick vs 3 inches for the R=10, at least as I've seen it. I've found both versions at Home Depot at the same time. I think the R=10 is more common.

why not just buy bag of r-13 insulation and cut it in pieces and tape it to fit around any water heater.

Asked by: thinker
I suppose you could but buy some extra tape. Results might not be as neat.

Can I use the silver duct tape to tape the insulation?

I bought this blanket at Home Depot, and it doesn't contain the tape that was supposed to come with the kit. Someone must've bought it and then returned it. Anyway, since this was the only one left in the store, instead of returning the item, can I use the silver duct tape to tape it together? Will there be any safety issues?
Asked by: KT
I did use some extra duct tape to complete installation.

Fiberglass Water Heater Insulation Blanket is rated 3.4 out of 5 by 89.

You would think this blanket with a length of 75 inches would do it, but no. It's about 10 inches too short. For a 50 gallon water heater with a circumference of 65 inches you need a blanket that is at least 85 inches long.

However with my particular water heater this didn't fit quite as snugly. This is no fault of the manufacture, just a circumstance of my water heater being in my attic in close quarters with the gas line/chimney. They give ample amount of duct tape to do this job, I had a lot of excess in fact. I urge you to read your water heater's owner manual to know exactly what to not cover up. Have a box cutter or razor on hand to cut where needed. Works best if done with a 2nd person to hold it up while you tape in place.

Rated 3 out of 5 by from In store options are very limited The girth of my 50 gallon water heater must be more than most because this barely fit around it, and I had to tug a bit. Probably should have two people for installation, unless your water heater is smaller. They also could have included more tape, as again was barely enough. If I were to do it over I'd probably use a different product more appropriate for the size and perhaps shop online to purchase a non-fiberglass option as well. It gets the job done but for a few bucks more, there are much better products.

This required no cutting aside from around the thermostat. My electric bill has gone down substantially since I put the insulation on. I highly recommend this product.

They say I bought this product, but it does not look like what was sent to me. It also did not fit the standard 40 gallon electric water heater...which is a problem I have had with other blankets as well.

Rated 4 out of 5 by from Thick with plenty of tape This is a nice thick water heater blanket. However, the fiberglass used is definitely old school. It is nothing like the new stuff from Owens Corning. Wear gloves to protect your hands.
