The Total Truck Heat System from Idle Free Systems Inc. eliminates the need for discretionary idling in cold weather conditions. The system consists of a coolant heater and an auxiliary AGM battery that work together to provide heat for both the truck's sleeper bunk and the engine, and eliminates the need to idle the truck's engine for interior heat (cab or bunk) and engine heat.

In addition, the Total Truck Heat system includes an independent auxiliary battery. When the driver initially shuts down the truck, the Total Truck Heat system takes advantage of the residual heat generated by the engine and circulates the heated coolant through the bunk's heater core, the cab's heater core, and the engine block. The electrical energy needed to move the coolant, monitor the coolant temperature, and maintain interior climate control is provided by the independent auxiliary AGM battery. When the coolant temperature falls to 140 degrees, the system's ultra-efficient diesel-fired coolant heater is automatically activated.

The system is capable of producing more than 17,000 BTUs per hour.  If run continuously, the system will use less than 12 ounces of fuel per hour.

The auxiliary AGM battery can provide power to the system for 10+ hours and never compromise the truck's starter batteries.  The auxiliary AGM battery is automatically charged whenever the truck's engine is running, and is automatically separated from the trucks batteries when the trucks engine is turned off. The optional programmable timer can be programmed to turn on at a designated time, so the engine block will be warm and ready to start.

The Total Truck Heat System can be installed on any diesel work truck. The system consists of several components that can be mounted on the truck's exterior in a variety of locations & configurations.  In addition to the AGM battery, battery separator and coolant heater, there is a battery box, power module, frame mounting brackets and optional programmable timer. The system can be easily installed in about three hours by a certified technician at either an Idle Free dealer or by a fleet's own technicians.

The Total Truck Heat system requires no regular maintenance -- just a yearly fuel filter change and an inspection of the system's electrical connections.
