I just buy what is at TSC. Have to admit, I have not purchased a heat tape "forever". Guess I got a good brand!! LOL
I do recommend buying those 4' insul tubes to put over the pipe & tape.
Richie fountains make one that is supposed to be hard wired to the thermostat but we just wire a pig tail on them and plug then in. They seem to be more rodent proof than the regular heat tapes.Any recommendations for a waterline heat tape/cable brand/model/source?
