THG heat tape

Unregulated THG heat tape should read how hot?

It can get up to 120 + even hot enough to cause damage. Never use a heat tape or mat with out a thermostat.

Okay mine is only reading 100-107 did I do something wrong? Im use to the older style of heat tape.

Why do you need heat tape to get that hot in the first place?

If it's getting that hot, it's definitely not on a thermostat.

Im aware I just like to know how hot it should get unregulated. I know about thermostats. Could we answer my question please, did I do something since it is only reading slightly above 100 degrees.

Just for fun or what?

There's not a set temperature so it will fluctuate. If you're really interested, then contact THG. They're pretty good at replying.

I can remember one time I ordered regular heat tape and the hottest it would get is 80 so I contacted the makers and it turned out I got a bad batch so I was just checking.

Just got word there was a thread here-

First, which width element are you using?

Next- the max temp can vary tremendously depending a few factors. Room temp and the surface it is mounted to are among the biggest. You will also see a lower "open air" temp than if you set something on it and start building up some heat. This is why you want to regulate it with a thermostat. These variable, especially room temp, can change with day/night and seasons.

I got the 11". I left it plug in for about a hour and a half and it got up to 135 was the highest I seen it read. I have jt plugged into my thermostat and every single tub reads the exact same temps (within about .5 degrees) with the older style tape I would be a degree or two higher in some tubs. THG will be my heat tape choice for now on.

The 11" will get the warmest of the group, good for back heat. You will need to regulate your temp and I would guess you have it mounted on something that is a pretty good insulator and a pretty warm room to get that temp output. I am glad to hear you are getting good results!
