what is the R rating of the Smart jacket water heater blanket?
1815906
Not sure of the R rating but it did make a difference in our electric bill since we have had it.

Similar products have a conductive insulation R-value of 6.5. However, the full insulation value also includes the aluminum foil on both sides of the double bubble insulation. The aluminum foil adds a reflective insulation value. The effect of both the bubble insulation and the reflective foil is said to reduce heat loss by 40 % or so. The aluminum foil reflective portion is said to be similar to the effect the foil has on the radiant heat entering your attic space.

I am not sure. I dont think it can be rated like typical insulation with an R rating. It is only about 1/4 inch thick but the reflective suface on both sides with the bubblewrap kind of middle stops all heat from coming through. Everywhere that is covered is cool. It works like my pool solar cover. Hope that helps

Sorry I don't know the R-value. It did work EXTREMELY in mine and my daughters house where I installed it. The cooling bill was reduced by 40% in both houses.

I do not know the rating. There is nothing printed on it anywhere that gives that info. Sorry.

I bought this last fall and have used it every night since. It works very well still and I am still happy with the choice. I haven't had to wash it yet because I place a sheet and thin blanket underneath. I am sorry for your experience and wish you well with the return. We had a similar experience with Edenpure heaters: we run two thar we would never be without but in the midst of that had one that ran our utility bill up to $300 and tripped a circuit breaker. Maybe you just got a bad one. My UPS driver suggests the possibilty of electronics being damaged by improper handling during shipping. I bought this last fall and have used it every night since.

Yeah, I would too. Especially because Consumer Reports rates the Honeywell HZ-817 as the #1 Natural convection space heater in the October 2010 issue. It's a CR Best Buy, with an overall score of 86 (the highest of any they tested) and a "very good" rating for safety. Consumer's Union tests these things well, and if it were unsafe they would know. Sounds to me like Robert Evans isn't sure what he's talking about. Was the HZ-817 even in production in 2009?

I don't know but don't waste your time with this heater. I returned it promptly. I was so dissatisfied. Did not do the job of warning me up under my desk at work. I returned it and got something from Staples and could not be happier. I can't remember the name but I can email you tomorrow.

I don't know, but I can tell you it was highly rated in Consumer Reports. I am very satisfied with it's simplicity.

The emergency blanket is less of a blanket and more of a tarp. It is much stronger and more reliable than the cheap mylar emergency blankets. it is basically a green tarp with one side having reflective material. It is not crinkly and loud like the cheap emergency blankets. It may be nice to line the floor of the dog house to warm it up, but I do not think it would be as cozy as a normal cloth blanket for nestling down inside. Hope this is helpful!

I don't think it had a rated r value. Since it it has a combination of a thin layer of foam and air I would think it would be high. while I used it primarily on long flights to Alaska to save my butt I also used it on outings while in the bush. Butt never got cold.....if that helps

Sorry don't know. I live in Arizona so cold weather rating not important to me

This switch is rated to switch 2400 watts of power at 120 Volts. If your water heater has an element that is less than 2400 watts, and runs on a 120 volt circuit, yes you can use this. It is not likely that your water heater meets these requirements. You can, however, use this switch to switch a relay that is rated to turn your water heater on and off. An inexpensive example of this is the Packard C230B. It will switch 220 volts up to 6600 watts and has a 120 volt coil. This is a mechanical contactor. You can also look for a solid state relay that will be quieter and last longer, but cost more. This switch is rated to switch 2400 watts of power at 120 Volts.

according to mfgr, not hot water rated unless specified as such. Company does make what you look for, contact them and they will point you to source.........hope this helps..........Dave

The info that comes with it lists it as "#10 STW 3 Conductor. 15A - 125V. -40 F Coldweather jacket - Water & Flame Resistant.

It's what is called a thermal resistance rating. Read this and you'll understand it easily. :) http://en.wikipedia.org/wiki/R-value_(insulation)

6 gauge, I can't recommend the model though. It caused lights in the room to flicker. I ended up getting an EcoSmart 11 EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology and changing the Rheem out fo the EcoSmart. The specs are the same for each model. 125 amp sub panel minimum, 60 amp dipole breaker for the 6 gauge wire that needs to be run to the unit

this is a blanket that is rated for between 25-40* F......had to send them back as they are much too heavy for the AZ area that they were meant to be used in. A great blanket and product...but better suited for the living conditions of horses in the north of AZ, mountain areas, etc. It is VERY warm and heavy. Great for CO and all parts north and east.

Hi there. This is an in-line thermostat for 220-240 VAC. It is rated at 3600 Watts at 240 VAC. plenty for any baseboard home heater. they work very well and are "smart" energy saving as they see the temp. rising and falling and adjust to meet the needs. (ie shutting odd a degree before reaching the temp. because the radiant heat will continue to rise. The slimline design are it's good and bad feature. They look great, but are not forgiving if the box is not cut well. They don't have a large "lip" in the back to cover poorly cut holes. I've installed about a dozen of them (to replace existing) and had to Spackle two so they would cover. Hope this helps. Hi there. This is an in-line thermostat for 220-240 VAC.
