2-Stage Energy-Saving Smart Unit Heater w/ Remote

KB ECO2S Works Smarter Not Harder by offering unparalleled performance, energy efficiency and user control of the in-built ECO2S electronic thermostat. Offering energy efficient 2-stage heating, with Eco mode that automatically uses the low wattage needed to heat the room, integrated fan only and timer modes, as well as a remote control for simple operation.

Safe Comfort For Large Spaces

Patented Smart Limit Protection (U.S. Patent #6,748,163 B2) automatically shuts power off to the heater in an abnormal event and must be manually reset for safety.

Spiral Steel Fin Heating Element For Maximum Heat Exchange

The metal sheath element is copper brazed with spiral fins then molded into a coil configuration. This combination produces the heat transfer while eliminating the potential for hot spots by positioning the element in the maximum airflow stream.

Engineering Specs

Contractor shall supply and install KB ECO2S Series garage heaters manufactured by King Electrical Mfg. Company. Heaters shall be of the wattage and voltage as indicated on the plans.

Construction: All exterior and interior metal enclosure parts are made from 20 gauge electrogalvanized Steel with a rust inhibiting baked enamel finish. Smooth rounded corners and protective edge trim give an attractive modern appearance.

Adjustable Outlet Louver: Louvers direct air up or down as needed for the heating application. Rear Intake Screen: Heavy gauge steel screen protects against foreign objects making accidental contact with the rotating fan blade.

Spiral Fin Elements: The metal sheath element is copper brazed with spiral fins then molded into a coil configuration. This combination produces the best heat transfer while eliminating the potential for hot spots by positioning the element in the maximum airflow stream.

Totally Enclosed Fan Motor: Permanently lubricated long life unit bearing motor with 20cc of oil. Epoxy-coated motor with enclosed rotor resists moisture and corrosion for long-lasting, trouble-free operation.

Aluminum Fan Blade: 5 blade fan mounted directly to the motor shaft for maximum efficiency.

Auto-Reset Thermal Cutout: Power is disconnected from the element if an overheated condition occurs. The fan continues to run to dissipate excess heat from the element. The element is re-energized automatically when the normal operating temperature returns.

Electronic Control: Up, down temperature mode. Start/Stop. Standard on all heaters. The control voltage is equal to the line voltage (208, 240) for 5kW models. Over 5kW the line voltage control is operating the contactors.

Easy Installation: A quick access panel located on the bottom of the heater allows for quick wiring and easy maintenance for the life of the heater. Includes universal wall/ceiling bracket for simple installation.
