Stiebel Eltron's surface-mount CK heater is made in Germany. Perfect in any location, this quiet fan heater quickly warms an area or maintains a comfortable temperature. Perfect for both retrofit and new construction, the downdraft design heats a space evenly. A CK can easily replace an older flush-mount heater. The adjustable thermostat to control temperature is located on the top of the CK. The frost protection setting will maintain above freezing temperatures in an appropriately sized space. The strong external casing is plastic and the entire heater is designed to have its components recycled at the end of its useful life. Stiebel Eltron is a world-leading German manufacturer of technically superior products since 1924.
