United Rentals carries a solid lineup of electric space heaters from trusted manufacturers like Heat Wagon. Heat Wagon's portable electric heaters feature a built-in thermostat that automatically cycles the heater on or off. Overheat protection will safely shut down the unit if the blower is restricted. Selected units listed may be ducted up to 50' with a 12" outlet; please contact a United Rentals representative for more information on which model is best for you.
