Designed and made in Germany, this quiet fan heater is perfect for both retrofit and new construction, the European downdraft design heats a space evenly. CK heaters easily replace older flush-mount heaters and are ideal for bathrooms, basements, offices, playrooms, 3-season porches, cabins, campers or RVs, and mobile homes. The built-in fan is extremely quiet in operation at only 49.7 dB. In rooms larger than 215 sq. ft., the CK can be operated through a conventional wall-mounted room thermostat. The CK is designed with a frost-protection setting. The lowest thermostat setting will maintain above-freezing temperatures in an appropriately sized space. The CK heater is designed to have its components recycled at the end of its useful life.
