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.

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

This question is from CK 20E Wall-Mounted Electric Fan Heater
Asked by
Read all my Q&A
February 21, 2016
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?

Customer Reviews

Rated 4.4 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Love them We needed some heat for our south porch where I keep many large plants. Winter in Iowa gets pretty cool and the heaters work wonderfully. January 1, 2016
Rated 2.0 out of 5.0 by Poorly designed I'm amazed that anyone would give this thing five stars. The design for installation is absolutely horrible. The punch out on the top of the unit leaves the hole in the wall where the wiring enters the unit completely visible giving it an unfinished, sloppy look. In order to circumvent this, you have to install a custom finish-work solution. Second, the mounting brackets are also poorly designed. Unless you have custom framed for this unit, you can't hit two studs to support the heater properly. Furthermore the bottom bracket is in the center of the unit, which means that it also will not be mounted to anything solid, unless you custom frame for the unit. February 17, 2016
Rated 4.0 out of 5.0 by They do the trick I bought two of these units to heat a 26ft x 26ft finished basement room. The basement doesn't drop below 50degF on its own so I just needed a unit to boost the temp 20degF. These units are very effective, infact I turned one of them off because only one unit is able to boost the temp 20 degF in a 675sqft room. I wired the two units to a programmable thermostat which they seem to work well with. The wiring of these units is pretty straight forward if you have even the slightest understanding of residential wiring. The only issue I have and the reason I only gave 4 stars is the fan is lowder than I had hoped. The unit is advertised as quiet but when the fan kicks on it is certainly noticeable. I suppose its not any worse than when a forced hot air furnace kicks on. January 19, 2016
Rated 5.0 out of 5.0 by Wall Heater Installation was easy, only fault is you can see the wiring coming out of the wall to the unit, but covered it with some aluminum flashing to dress it up. December 29, 2015
Rated 5.0 out of 5.0 by 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. January 5, 2015
Rated 5.0 out of 5.0 by 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. October 26, 2014
Rated 5.0 out of 5.0 by Very Pleased We purchased this heater for our three season porch that we would like to use a half dozen days in the winter, here in Vermont. It is trim looking, well made and easy to install and best of all makes our porch useable on the coldest of days. December 26, 2014
Rated 4.0 out of 5.0 by So far so good, but it's early yet Home Depot solicits these reviews too early. I just installed it and that was pretty straightforward. But I will need a few months of winter operation to know if the heater really does the job. It seems to put out a good amount of heat, so we will see. October 7, 2014
