1. A generator set configured to provide an electrical output to an external electrical load, the generator set comprising:
an electric generator configured to couple to the external electrical load;
an engine configured to drive the electric generator, the engine including an engine block;
a heating system in fluid communication with the engine block, the heating system including an electric fluid heater, wherein the electric fluid heater includes a resistive load configured to supplement the external electrical load; and
a control system for:
monitoring a first parameter of the engine;
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 the electric fluid heater in response to the first control signal;
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 heater in response to the second control signal.
