Our new van has an inboard water tank shrouded in closed cell foam, the water heater is a Belling, it is enclosed in a polystyrene Jacket. the van is 1" thick closed cell foam sandwich construction one piece body and floor as well. Does anyone have similar and left water in over a real cold winter when it is only used occasionally. what does the panel think (currently drained down and bottles of water left in to see if it freezes).
