I doubt that a ferry going to Spain would see sub zero temperatures especially if the outfit is inside the ship. But even outside temperatures are influenced by the temperature of the ocean. It’s not a PQ17 journey to Murmansk.Can anyway recommend a good, easy/ not too technical way to remove water from the system, should a sudden freeze happen?
Not only for at home when the van is on the driveway, but also for if I was on a 2 day ferry to Spain in subzero temperatures out at sea?
Most caravan systems would blow apart at 15 bar!i use my tyre inflator to pump 15 bar into system, plenty of vids on you tube.
