Heat Tracing On ABS And Pex Lines??


A quick electrical/mechanical question for the pros:

Drawings show ABS drainage and PEX for the supply, and portions of this work is exterior, so the lines need to be heat traced and insulated.

Can PEX and ABS be heat traced, or do I need to run Ductile Iron for my waste and Copper for my supply?

Mods - this is a grey area - electrical or mechanical forum?

Many thanks!

Your question is out of my league, but I'm guessing you'll have the best shot for an answer in Plumbing.

I'd be interested in hearing the definition of heat tracing in this context.

Any plumbers out there have experience with heat tracing requirements on PEX and ABS lines?

Re: Heat Tracing On ABS And Pex Lines??


I had some google links for you last night, but I pressed the wrong button and they disappeared. But what I found out was that several manufacturers make heat tape which can be applied to PVC water pipe. I didn't check on the other items. I suggest that you find and speak to a knowledgeable salesman at a supplier, or to a manufacturers sales rep. I'm guessing that as PEX becomes more common, that this question has been dealt with before.

The ABS waste lines have another issue, and that is most heat tape is meant to be used on pipes which are full, and thereby have a greater thermal- and physical mass. DWV are empty the majority of the time.

But I live in an area where heat tape is not that huge of a necessity. In the snowy northland, there has to be a lot more need, and many more people with experience in this.

Also, if the drawings show heat tape, maybe the architect or designer should give some specs
