During the colder months of the year, some commercial and residential vehicles utilize engine block heaters to provide a number of benefits, including quicker start-ups, fewer pollutants, and less engine wear and tear. Conventional engine block heaters draw a constant amount of power, typically between 0.5 and 1.5 kW, whenever the vehicle is plugged in. Engine block heater controls allow the heaters to be turned on less frequently with the use of temperature sensors and timers, leading to significant energy savings potential. This RTF UES measure covers permanently-installed engine block heater controls (either wall-mounted or engine-mounted) for both non-residential and residential vehicles.
