Product Overview

Stiebel Eltron’s elegant surface-mount CK heater is perfect anywhere quick heat is needed. Designed and made in Germany, this quiet fan heater quickly warms an area or maintains a comfortable temperature. 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. A thermostat with an adjustable knob for setting temperature is located on the right side of the CK. 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 external casing is made of stove-enameled sheet steel. The sides are made from plastic. The CK 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.

Can they be mounted on the outside of a wall or does part of it have to be inside of the wall

Asked by: mike
The entire unit must be mounted to the wall surface. None of it other than the feed wire from the service panel goes inside the wall.

Is there smaller sizes for small heating load requirements. what is the air flow of these units.

Does it have more than one speed
Asked by: Tarek
Thank you for your recent inquiry with The Home Depot, Tarek. We carry a CKT 15E Wall-Mounted Electric Fan Heater with Timer Internet # 204091962. Rather than the 208v or 240v of the CK20E, the CKT15E is a 115v model. They both have a timer and heat setting but not an air flow setting. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

Branch Circuit

I have read a few reviews that people have hooked a couple of these units to a thermostat. The directions call for a 15 amp branch circuit for the unit, so technically you can't have two of these units connected to a thermostat as they theoretically would draw over 15 amps. So, is this unit ok to connect to a thermostat that controls this unit as well as a 1500w/240v baseboard on a 20 amp double pole circuit?

CK 20E Wall-Mounted Electric Fan Heater is rated 3.9 out of 5 by 15.
Rated 2 out of 5 by from Dumb design! As others have stated, it's a very nice looking unit and functions well BUT the electrical connection is highly visible at the top of the unit. If you don't mind seeing an electrical wire running into the unit then fine, but I think most people would rather have that covered. Steibel Eltron should offer a cover for this part of the unit. Very disappointed in current design.

Rated 3 out of 5 by from Heater Installation This is intended for new construction where the wall is open and mounting wood can be installed. The online manual and the manual that comes with the unit are not accurate. They both show the electrical connection in the center of the unit. In reality it is only an inch and a half down from the top and impossible to hide. I took a duplex box turned it horizontal instead of vertical but because the unit stands off from the wall to allow ventilation most of the box is visible, see pictures. The second problem is getting the wire from the box to the unit in any type of conduit. This really isn't possible. The unit has to slide down on the hanger. I found a thin wall conduit fitting that I attached to a metal cover on the box and once it was in place I was able to slip and insulation bushing from the unit into the conduit fitting. The box and conduit fitting are visible in the finish insulation, even though they are level with the top of the unit because of the stand off.

Rated 5 out of 5 by from Winter Cabin Heat This heater was purchased to keep a winter cabin equipment room from freezing. It works great.

Rated 5 out of 5 by from Toasty Warmth Purchased this to replace our bathroom's existing inefficient electric baseboard. Placed with minimal rerouting of current wiring and super easy installation. Waited until cold, cold, cold outside temps to give this review. Finally, HEAT on demand. Love it, simply Love it.

Rated 5 out of 5 by from OMG where has this been all my life !!! Easy to install, 220V input. INSTANT heat !! Thermostat works just fine!! Warms whole bathroom almost instantly. Simply cannot believe the marvelous design of this unit! I waited to Review until cold weather started setting in so I could actually feel how effective it is. It works so well I'm seriously thinking about replacing a couple gas wall heaters that we have in 2nd bathroom, and in Sun-room reserved for plants and pets.
