I screwed them down and wired them together off the 120v circuit in the fresh water tank area. Running them on low they don't pop the breaker even if they are both on.
I've never really been single digit temps for more than a day before so I don't know how the water heater area would hold up. I assumed just having the water heater over there would have keep the lines warm enough if it was on. It a long way from the heater on the waste water side over to the water heater area.
