Forget subzero, is it OK in 120 degree weather?

It is a very well made and substantial power cord so it should be OK at any temperature several degrees below the melting point of rubber.

I have measured temperatures of my solar heater surface at or above 120 degrees. It works fine in that range.

Yes, install one operating at a temperature of 65 degrees Celsius and have not had this problem some above 140 deg. F.

No. This is a great system that has operated perfectly for several years at 120 volts a/c.

You can have it at any level, but there is a safety buffer at 40 degrees. There is an option to turn off completely as well.

No. You can not run it with air temperatures over 140 degrees either or the motor will burn up.

Each person is different and their tolerance to climate is going to be different. I tend to overheat easily and found that 45-65 with this product is great. It keeps me cool in the warmer weather and warm in the colder weather. However 65 might be the extreme of this weight. I would suggest a light weight merino wool base layer if you are going to be in 60+ degree weather. You can always strip down a layer but it is hard to strip off your base layer :)

It won't make water higher than 120. So &lt; 120 is a good attempt to answer your question. If you are pre heating with solar, you prob. are limited to around that temp.

Not really a problem, and I was a bit surprised, as I wore it on cold days riding my bike. It was fine at 40 F.

I'll give a qualified 'yes.' I've been buying these from another source (Amazon can't meet my quantities) but the same exact item and their specification says 200° F max. A word of caution though: I would not recommend taking the temperature too close to the maximum. I think you'll be fine at 140°F.

Are you sure your cold water temperature is 100 degrees? Average is around 55 degrees.

I do everything in Fahrenheit, but I THINK that is about 95-100 degrees. For what I am doing, I keep it on about 124 degrees and it holds one degree either way, so I would say it SHOULD be OK for what you want.

Yes, product details says so. Sure don't have cold air coming down mine! :-)

I've taken it up to 450 degrees without any problems. I'm sure you can take it to a higher temperate. Great product.

140 farenheit I have mine set at 125 The manual tells you how to change it from the 120 factory maximum, it is very easy to change.

It worked fine for me at 24 degrees F. I am sure that it would work well below that.

I am using it on 120 and Love it with no problems. Anything beyond that I don't know but betting you cannot
