Preventing frozen water pipes in open crawlspace

We recently bought a seasonal cabin in a climate where winter temps can reach -20 F.  We want to make cabin to year round use.  A new waterline coming into cabin is below frostline but all pex tubing to bathroom and kitchen are exposed under cabin.  My plan is to install rigid insulation boards under cabins perimter to create a enclosed crawlspace.  Will heat tapes or freeze protection system inside main line be enough to prevent freezing waterlines?  The cabin does not have much for inside walls most waterlines are on exterior walls.  A photo is included

Re: Preventing frozen water pipes in open crawlspace

Hi William, the TOH Discussion area is kind of dead since it was changed over. I'm not really experienced in this stuff, but I'll offer my advice.

All of that piping is definitely exposed. I can only imagine that during the winter if there is any water in there, it's probably going to freeze and burst. If it were me, I'd try to wrap all the lines outside of the house with as much insulation as I could (not sure how much that'll help. 

For all the lines underneath, I'd try to frame in a small floor for them... perhaps install 2x4s under the flooring there, and build an underneath box for the tubes, then place insulation in there, and finally, a piece of plywood to cover it all. That's probably all you can do.
