A system for use with a block heater connected to an engine for pre-start heating of the engine. The system includes a power source, a relay assembly coupled to the power source, a temperature sensor, and a controller. The relay assembly, when closed, electrically connects the power source to the block heater, to thereby energize the block heater to heat the engine.
