The KBP Series 2 is the new industry standard for multi-wattage unit heaters. Built on the trusted legacy of the original KBP, Series 2 delivers smarter design, improved controls, and easier installation.
Designed for rugged performance, the flow-through design efficiently moves air by pulling air from the back of the heater and discharges it out the front, easily heating a large space. Built with high quality components and suitable for both residential and commercial applications.
All models include a standard built-in thermostat with easy-connect terminal block to field convert to a remote line voltage thermostat.The integral fan delay continues to dissipate heat from the elements during the cool down period, maximizing the heat exchange in the room. King’s exclusive dual Pic-A-Watt steel fin elements allow customers to select from a range of wattage options, Dual Pic-A-Watt® elements tailoring the heater to an area’s specific heating requirements.

Product Features

The Industry Standard.

The industry standard for multi-wattage garage , shop and even greenhouse heaters. Standard models include a built-in thermostat for accurate temperature control, with an easy-connect terminal block to field convert to a remote line voltage thermostat.
An optional field-installed 3-position switch (Heat/Fan/OFF-DISCONNECT) is available that can be easily added if needed. Designed for rugged performance, the flow-through design efficiently moves air by pulling air from the back and discharges it out the front, easily heating a large space.
Now That’s Smart!
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.

Engineering Specs
Contractor shall supply and install KBP Series 2 unit heaters manufactured by King Electrical Mfg. Company. Heaters shall be of the wattage and voltage as indicated on the plans.
Pic-A-Watt Heating Element: Exclusive King multi-tap element allows field adjustment to several wattages at time of installation. Steel sheath elements of various resistance are copper brazed to steel plate fins producing a multi-wattage heating element.
Thermostat Options:
Built-in Thermostat: Single pole factory installed hydraulic capillary tube thermostat for precision heating control. Operating range 40° to 90° F. Includes an Easy-Connect thermostat terminal block to field convert to accept a line voltage (240V/25Amp) remote thermostat.
Optional Heat / Fan / Off-Disconnect Switch Kit Available: 3-position switch provides heating and summer fan only operation. The combination 2-pole for 1-phase and 3-pole for 3-phase switch provides a “positive off” that disconnects all ungrounded conductors.
Fan Delay Switch: The fan continues to operate after the thermostat shuts off in order to remove the residual heat left in the elements. Power must not be interrupted.
Adjustable Outlet Louver: Louvers direct air up or down as needed for the heating application.
Rear Intake Screen: Heavy gauge steel screenprotects against foreign objects making accidental contact with the rotating fan blade.
CFM: 385
Universal Mounting Bracket: Combination ceiling/wall bracket is included with every heater. Allows for 15-degree downward tilt.
Unit Bearing Motor: Permanently lubricated, long life, unit bearing 4-Pole motor with 20 cc of oil. Enclosed rotor provides long-lasting, trouble-free operation. Thermally protected. 1500 RPM.
Patented Smart Limit Protection (U.S. Patent #6,748,163 B2): Equipped with King’s patented thermal overload Smart Limit Protection®, which disconnects elements and motor in the event normal operating temperatures are exceeded. If thermal overload trips due to abnormal operating temperatures, thermal overload shall remain open until manually reset by turning the heater off for 15 minutes. Automatically reset of thermal overloads, which allow the element to continue to cycle under abnormal conditions, will not be accepted.
Standard Color: Onyx Gray
Easy Installation: A hinged 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.
Approvals: cULus (E41422)
