The KBP ECO2S+ series compact unit heater delivers exceptional performance, energy efficiency, and user control, featuring King’s innovative built-in ECO2S+ electronic thermostat with remote control. The heaters provide energy-efficient 2-stage heating, an Eco mode that automatically uses the lowest wattage needed, integrated fan-only and timer modes, and a convenient remote for simple operation.
With the ECO2S+ Remote Temperature Sensor, the heater detects the room’s cold spots and adjusts to maintain comfort throughout. Simply place the sensor on a wall or shelf to ensure the ideal temperature exactly where you need it.
The unit also includes a standard provision for an optional 24V thermostat, allowing for remote temperature control or integration with a building management system (BMS). Combined with summer fan-only and thermostat timer modes, the KBP ECO2S+ adapts to your needs year-round.
Built for rugged performance, the flow-through design efficiently draws air in from the back and discharges it out the front, quickly heating large spaces. An integral fan delay continues to circulate heat during cool down, maximizing warmth. King’s exclusive dual Pic-A-Watt steel fin elements provide a range of wattage options, letting you tailor the heater to the specific requirements of any area.
