Unless valved off, the main engine water pump always circulates engine coolant through the AH heater all the time the engine is running.
In temps below 50 to maybe 45 degrees F, the 3/4 inch hose can not transfer enough heat to keep up with the demand for interior heat. So in cold conditions, turn on the diesel burner.
