Classification: CPC F  H | IPC F  H

Claim 10:
11. A method of operating a generator set to provide an electrical output to an external electrical load, the method comprising:
monitoring a first parameter of an engine that is configured to drive an electric generator, wherein the engine includes an engine block, and wherein the electric generator is configured to couple to the external electrical load;
generating a first control signal in response to the first parameter being less than a first threshold;
increasing the external electrical load by turning on an electric fluid heater of a heating system in response to the first control signal, the heating system in fluid communication with the engine block, wherein the electric fluid heater includes a resistive load configured to supplement the external electrical load;
monitoring a second parameter of the engine;
generating a second control signal in response to the second parameter exceeding a second threshold; and
turning off the electric fluid heater in response to the second control signal.
