Answer This Question
A: That depends on the shape of your tank.
Measure the circumference and height of your heater.
I have a 50 gallon tank and it fits just fine.
The white tape that comes with it leaves no room for mistakes.
I did the job myself. Two people would make it easier.

A: You will need to check with Reliance. All we can tell u about is the water heater blanket.

Answer This Question
A: It is not fireproof. It is safe to use as long as you do not cover the fire box. The blanket goes above it.

Just large enough for a 45 Gal. ITCHY.
Was *just* large enough to fit my 45 gal Indirect water heater (SSU-45N). *TONS* of fiberglass in the air when manipulating it, WEAR FULL CLOTHING AND MASK + EYE PRO.
It did come with some tape. I installed it by myself, so I used some painters tape over the top of it attached to the heater to keep it in place while I worked my way around it and did the necessary cuts.
Didn't come out perfect but it'll work.

NOT long enough!
Very easy to install but blanket wasn't long enough to reach around my tank! I have a new 50 gallon Rheem-PROE50M2RH95 electric water heater, measures 70" around. Instructions state the blanket is 75" long, was about 5" short of the ends coming together. I didn't have to trim any off or leave openings for access panels. I'm guessing the 3" thick insulation takes up the needed length. Future productions need to be 80" long! I have 98% of tank covered, guess that's better than nothing.

Serious Energy Savings
Made a great water heater jacket! Was simple to work with. After applying some reflective foil-clad bubble insulation, I fashioned battens (of the same stuff) to create an air gap. The Frost King insulation, then, was applied as the 'outer jacket.' It was light enough to be easily supported, while comprising the air-sealing layer of that composite cross-section. Thus I benefit from the combined R-values of the (1) bubble foil, (2) air gap (substantial!), and (3) the Frost King, itself. I immediately saw a reduction in energy consumption. Even though my water heater tank is a well-insulated (from the factory) heat pump-driven model. Do spend money on good wide tape compatible with the mylar facing. Apply it neatly and thoroughly without creases. I was able the use semi-rigid foam and outline "service ports" in the insulation jacket where it was pre-cut for foreseeable maintenance access; allowing it to be re-sealed and re-used in the future.

This is R10. I did have to tape it to the top of the electric water heater cause it kept slipping off. I did it alone but would be easier if two people did it. Used the scrap peices for the top of it.

Came with everything needed to install on to the heater. Instructions followed simple and easy. As instructions state protect yourself with clothing, gloves, and glasses to protect from fiberglass. Even a light mask for the mouth will help. I added a little tape around the openings to protect, trim and help hold it in place. Fifteen / Twenty minute install time.

Installed this on a 40 gallon electric water heater in about 20 minutes. Fit very well. Covered entire vertical surface and only overlapped a few inches so I did not trim it at all. Only had to cut a slit at bottom for drain valve. Did not cut out for thermostats. I will do that only when I need to. I can feel the thermostat covers thru the insulation so it should be easy to do if required. Since I did not trim I had nothing for the top. I will do that with rigid foam I have left over from a different project. They claim the insulation is 3" but not after being folded, rolled and vacuum packed. I doubt you get the claimed R10 insulation value but it's better than most others I looked at in competitor's stores around here in South Texas.

Too small for a 50 Gallon water heater with a circumference of 65 inches. 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.

"Up to" 60 Gallons...if you by the correct model number
I couldn't help but notice how almost everyone commented on the fact that there wasn't enough material. Pay attention to the model number - SP57-11C. If you go to the Frost King website, you'll see there's another model SP60 which is 90 inches round vs. 75 inches. That's the model that fits up to 60 gallons.
