We camp in Colorado during October and November. Sometimes the temps get into the single digits. When temps are predicted to drop below freezing we disconnect the city water (required by the camp). I keep around 50 gallons in the fresh water tank, where one of the furnace outlets is located. However, it does not keep the water control compartment from freezing. I bought a small ceramic space heater and set it up close to the pump.
