ENGINEERING SPECIFICATION SHEET Simply the Best CK & CKT 15 E Surface-Mounted Electric Fan Heaters Description Stiebel Eltron CK wall-mounted electric heaters are designed for installation where quick heat is needed, such as bathrooms, kitchens, bedrooms, hallways, playrooms and garages in new construction and renovation projects. They have an ultra-quiet fan and will replace existing recess- mount heaters. A built-in thermostat has a frost protection setting. CK heaters will work with wall thermostats in rooms larger than 215 sq. ft. (20 sq. m.) The CKT adds a 60 minute timer designed to temporarily output maximum heat to quickly warm a space. When the timer goes off the unit CK without timer reverts to the thermostat setting to maintain comfort.
