Just bought a 100 yr old house in the northeast. the house was used as a
summer vacation home, and shut down in the winter. It is built on a stone
foundation, with a cinderblock crawl space under the kitchen. I put a 15ft
heat tape (previously used in crawl space) on the two pipes, encased them in
pipe insulation foam, then boxes the pipes, with insulation above and
around. Yesterday cold water pipe froze.(outside temp 2, temp in crawl space
24) I turned on power to heat tape, and was surprized this morning to find
the temp of the cold water about 100 degrees. Is this normal for heat tape.
Should I be regulating the tape to limit heat. Does this seem safe from a
fire hazard standpoint?
I grew up in cold country and all of our heat tapes had t-stats on them.
They cost a bit more but my father, more likely mom was worried that we
would forget about them in the non cold months.
Yes when the tapes are in direct contact with the pipes the water will get
quite warm. Once you start using the water the pipes will cool down quickly.

We get minus 30 here and I have 3 ft of semi exposed water pipe.
I removed the heat tape 5 years ago to reinstall it correctly and never put it
It's costs me nothing to crack open the laundry room sink tap.
No water shortage here so I feel this is my best solution.
Heat tapes not connected to a GFI have a nasty habit of lighting on fire as
Did you wrap the heat tape around the pipes.
That is a no no in most areas.
Fifteen feet of heat tape is usually for 15 feet of pipe.
Even with that much insulation it shouldn't heat the water that much.
