We had the heating on over the weekend - all we managed to do was fill the van with smelly dust particles! The heat managed to come out from beside the warm air heater and slightly from the vent nearest the door. How long should we expect the heat to take to get to all the vents? What is the thermostat near the sink to be used for? It says "dot ; off position: and A". Is this used to moderate the temperature? Mind you the van comes directly from Germany perhaps that makes a difference to the instructions. Any help would be greatly appreciated - we were freezing on Saturday night. We turned on the hob to keep us warm! Thanks.
