I'd give it a full day to warm up before moving the snakes in. Also, the electrical tape will probably be safe, but it's not very practical. The heat will cause the adhesive to get very gummy and it will probably slide around or become unstuck eventually. I would suggest getting aluminum tape that you can find at HD or Lowes. It's designed for higher temps and won't become unglued over time.

Oh, and 92 should be perfect for the warm side.

Good luck!!
