Heat tape

Not sure if I put this in hype right place so sorry if I didn't
My heat tape failed in this last deep freeze and my supply line froze
I'm in the process of replacing the heat tape and insulation
So my question is it possible to over insulate?
I was going to use the foam pipe insulation and the wrap everything with 2 layers of fiberglass pipe wrap
Live in montana so cold winters are the norm
Thanks randy

Is the supply line in the cellar? If so, what's the temp there?

It's important to make sure that the heat tape you use can be covered or insulated over.

Some heat tapes have thermostats. Make sure it is exposed to keep the tape from shutting off too early. The heat tapes should tell you how much insulation it requires.

Heat tape I bought a couple years ago has a thermostat against the pipe and it must be insulated like the rest of the pipe or the tape can overheat. Also, you can only use the pipe wrap, NO foam because of overheating and fire.

Not like the tape of old where the thermostat was in free air, when it got cold it came on and stayed on. Trying to conserve electricity I guess.

Read the directions.
