Control panel for energy efficient operations of vehicle warmers

A vehicle fluid heating system for achieving an elevated predetermined fluid temperature for at least one fluid of a first and second vehicle during an idle period having a duration defined by a start point and an end point, the hearing system comprising

• a first vehicle fluid heater configured for being coupled to the first vehicle in thermal communication with the first fluid of the first vehicle, and a second vehicle fluid heater configured for being coupled to the second vehicle in thermal communication with the first fluid of the second vehicle,
• at least one temperature sensor for sensing a temperature of a temperature source that has a correlative relationship to the first fluid of the first and second vehicles,
• a settable timer for enabling the user to establish the start point and the end point of the idle period of the first and second vehicle heaters,
• a controller in communication with an electrical source for controlling the flow of electricity from the electrical source to the first and second vehicles fluid heaters, in communication with the temperature sensor for receiving temperature information, and in communication with the settable times for obtaining information about the start point and the end point of the vehicle idle period,
• wherein the controller includes a processor for receiving the temperature information, idle period start point, and idle period end point for determining a vehicle fluid heating interval having a duration less than the duration of the idle period that achieves the elevated predetermined fluid temperature at the end of the idle period and a switch actuator for allowing the flow of electricity from the electrical service to the first and second fluid heaters during the fluid heating interval.
