Thermal energy is provided to a vehicle (20) that operates efficiently when operated for at least the duration of a minimum operational cycle. A reservoir (25) contains heat transfer liquid having a thermal capacity selected so that the burner must operate at its rated thermal output for at least the duration of the minimum desired operational cycle to provide the selected thermal capacity to the reservoir (25). With the liquid in the reservoir at maximum operating temperature and the burner off, heat is transferred from the thermal reservoir (25) to meet thermal demands of the vehicle (20). These demands decrease the temperature of the liquid to a minimum operating temperature, whereupon the burner is operated for at least the duration of the minimum desired operational cycle to raise the temperature of the liquid to the maximum operating temperature. |
