A method of conserving energy during a heating event in which a coolant is heated in a cooling system is disclosed. The method includes the steps of establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point. Also, a cooling system comprising a propulsion system 12, a coolant heater 14, heat exchangers 18, 22, a bypass line 24, and first and second temperatures sensors 16, 26. |
