Heat tap works pretty well....The P-trap is a very very easy thing to forget can be an issue. 

@Jules Aton  depends where the pipes are.It is outside wall and under the house pipes most at risk and if you think you might have an outage set the heat up a little so it will take longer to cool to freezing temps.

Get a few more opinions on that heat exchanger.
