We had 20 degrees this morning here in Alabama and the first time we have been living in the coach with this cold of temperature, at home I blow all the water lines out and put antifreeze in the traps and toilet but we are living in it so I prepared for this unusual weather by disconnecting from water and sewer and closing off any hole going under the coach. I am not up to speed on the heating of the water and aquahot bays and have a few questions. We have a thermostat in the aqua hot bay and a water to air heat exchanger with a fan on it but it doesn't seem to be working. Where does this heat exchanger get its fluid from and what pump is used for it? On the water bay side I have a thermostat that is controlled by pressure bulb type system and a electric looking heater just above the tank, I can turn this on with the thermostat but it either is a very low temp output or its defective. Does this unit put out hot air or just warm air? Is there any heat exchangers in the fresh water tank?
