The DeLonghi DCH1030 Safeheat 1500W Basic Ceramic Heater features two heat flow settings. Choose the high setting for 1500 watts or the low setting for 825 watts. The adjustable thermostat lets you easily select and maintain your desired level of comfort. A power indicator light for safe operation indicates when the heater is on. For minimal heat temperature, the anti-freeze setting automatically turns the unit on when the temperature reaches 44 degrees fahrenheit. If the unit becomes too warm, the safety thermal cut-off automatically turns it off.
