I live in Minnesota, if you look at the weather reports for here, we have had a lot of below zero days. My new system sits in the porch which is not heated, and I had to test the pump the other day... I do drain the whole system when I am done. The pump sits at the lowest point in the set up and then I put a valve after it for draining, after the system is drained, I take my air compressor to the line and blow the system out to get any residual left over water. This does well.
Your idea for portability is a good one though so if it isn't a lot of hassle, design it that way and then you do not have to worry about it. S.
