The Frost King SP60 isn't really an unconventional offer and it will be able to fit quite a variety of different customers looking to reduce standby heat losses or to save some money on energy bills. But it will be particularly useful for people that have their water heater placed in an unconditioned space (a basement, attic, or a garage) or for those that absolutely do not want added heat.

AES Nasa Tech

Two Pieces are Better Than One

AES Nasa Tech is everything people have come to expect from water heater blankets and then some for good measure. First off, you get not one but 2 different blankets. And that's definitely a change in the right direction as it makes the whole thing much easier to install and a lot more convenient to handle.

Both pieces are made of a polyethylene foam and aluminum foil. The materials in question are easy to clean. They do not contain any toxic or carcinogenic elements. The blankets are mold- and mildew-resistant. They do not get affected by humidity and moisture.

The lightweight product is really easy to install and it isn't just because it consists of 2 blankets instead of 1. In addition to these water heater wraps, you get spacers, foil tape, and an insulation hypo-allergenic kit.

Sure, it will still take some time to put it all together and properly adjust the blankets to the heaters. But it shouldn't take too much of your time nor will it likely require a considerable amount of effort on your side.

Just like every other model in this review, this 2-piece set fits gas, oil, or electric water heaters up to 60-gallon in size. It improves the recovery rate of your water tank and reduces heat loss by about 40%.

All in all, what we have here might very well be one of the most flexible and versatile offers on the market that we could easily recommend to just about anybody regardless of the size and volume of their heater or how experienced they are with these thermal things.

REFLECTO-FOIL 43180-74595

Make Smokey Bear Proud

Generally speaking, water heater blankets don't really differ that much from each other as they serve a relatively singular purpose, so the manufacturers often rely on some of the same solutions in order to achieve their goals. That said, it is a bit of a different story with the product that we have here. Instead of relying on tried and tested materials, the manufacturers created their very own Reflecto-Foil™ wrap that seemingly offers the best of what other materials have to offer without following in their footsteps when it comes to their flaws and inconveniences.

There are no foam spacers here as they are a fire hazard. The material in question isn't toxic nor is it carcinogenic as some of the other offers out there often tend to be. All in all, the whole thing features a Class A fire rating, and that's quite impressive given that it stops up to 97% of radiant heat loss and does an exceptional job maintaining the standby water temperature.

Finally setting the materials aside, we would also like to mention that, in addition to the roll of tape that usually comes with these products, the manufacturers have also decided to throw in complimentary spacer strips that will definitely come in handy during the process of installation.

All things considered, the REFLECTO-FOIL 43180-74595 water heater insulation blanket is fairly lightweight and really easy to clean. But, more importantly, their very own Reflecto-Foil™ is easily one of the safest and most reliable materials on the market.

Thermwell SP57-5

Longevity Case

Thermwell SP57-5 is satisfactory. There really isn't that much to it. It does its job and it does it well enough. What you get in exchange for a modest sum of money is a roll of tape and a single blanket that adds up to 75" x 48" in overall size. Other than a couple of scissors, the tape is the only thing you'll need to install the blanket, so you really don't need anything else. The blanket itself is alright, nothing to complain about but nothing we haven't seen before either. The R-value of 5 means that the wrap is one and a half inch thick. For most water tanks, it will be more than enough to significantly reduce the recovery time and heat loss.

As per usual, the water heater blanket is made of vinyl-backed fiberglass. The material has its flaws but there's a reason or two why it is the prevalent choice for most of these blankets. Its flame-retardant features are top-notch. Plus, the material is particularly corrosion-resistant, an important quality that significantly improves its lifespan.

Aside from its underwhelming R-value, the model isn't any less flexible than most of its counterparts. It works just fine with gas, oil, or electric water heaters from 40 to 60 gallons in size.

In short, Thermwell SP57-5 will help you cut energy costs. It won't cost you too much. It will most likely fit your water heater. And it should last for years to come.
