We are plumbing a pole framed cottage raised above grade, open crawl space on all sides, cellulose insulated 2X10 floor joist cavities. The shower/tub trap as well as all other drain, waste and vent connections will be below floor in unconditioned space (western NY state - windy and cold).

Is there a suitable/plausible heat tape - themostatically controlled - that can be safely wrapped on these drains?
