The CK Premium is an elegant surface-mount heater, perfect anywhere quick heat is needed. The electronic digital control with illuminated display includes programmable timers, a variable timer for booster heating of up to 120 minutes, open window detection for energy savings, and a child protection mode. A self-learning program in timer mode will pre-heat the room so the desired room temperature is achieved at the programmed time not after. Designed and made in Germany, this quiet fan heater quickly warms an area or maintains a comfortable temperature. The built-in fan is extremely quiet in normal operation at only 48 dB(A), and has a “silent-mode” with reduced power at only 37 dB(A). The CK Premium frost-protection setting will maintain above-freezing temperatures in an appropriately sized space. The thick aluminum face stays cool to the touch. Perfect for both retrofit and new construction, the European downdraft design heats a space evenly. CK Premium 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.
