Product Overview

Stiebel Eltron’s CKT heater starts with our CK heater and adds a 60 minute timer designed to temporarily output maximum heat to quickly warm a space. When the timer goes off the unit reverts to the thermostat setting to maintain comfort. This elegant surface-mount fan heater is perfect anywhere quick heat is needed. Designed and made in Germany, the heater quickly warms an area or maintains a comfortable temperature. Perfect for retrofit or new construction, the European downdraft design heats a space evenly. CKT 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 CKT. In rooms larger than 215 sq. ft., the CKT can be operated through a conventional wall-mounted room thermostat. The CKT 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 components of a CKT heater can be recycled at the end of its useful life. Stiebel Eltron is a world-leading German manufacturer of technically superior products since 1924.

Customer Reviews

Rated 3.8 out of 5 by 8 reviewers.
Rated 2.0 out of 5.0 by Disapointing Purchase The timer is manual with limited duration. Needs some trim on top of the unit to cover electrical connector and prevent debris from falling behind the unit. Electrical feed should be from the bottom. May 10, 2015
Rated 4.0 out of 5.0 by Does what it should. Easy install one of the only flush mount heaters i could find to replace my old one. Would of gave 5 stars if it had more than one spot to bring the wire into the product. But other than that works great is quiet and puts out good heat for my full bathroom. March 14, 2015
Rated 2.0 out of 5.0 by Too many cycles installed unit last year in bathroom which is 30' from our bedroom, but you can hear it run and it comes on a lot! By that I mean that the heater is noisy and cycles far to often. The short cycles are great if you want to keep a room exactly on set point, but a wider temperature span would reduce electrical cost, The electrical connection is on the back but near the top of the heater so you can see the wire connection when looking down at the heater - should be on the bottom. December 3, 2014
Rated 4.0 out of 5.0 by "Flat out" flame thrower! I can't say enough about the level of heat this heater puts' out, over the top levels of heat. The timer function is not very good. I'll be placing a complaint with the company. There is a sticking point at about the 10 minute mark in the timer internal routery element, a little aggrevating. Did I mention the heat output, remarkable! October 27, 2014
Rated 5.0 out of 5.0 by This heater is excellent! I purchased two of these heaters for a recent basement remodel and they are absolutely wonderful! My basement is approximately 900 square feet and has two sections that are separated by French Doors. In the past, I used baseboard heat, along with an electric fireplace insert in one section, and a picture wall fireplace in the other section. Given the cold winter that we just experienced, the temperature never rose above 72 degrees in my basement and at times it was quite chilly! My new wall heaters are very efficient and very attractive in my newly renovated space. The heat blows outward, as opposed to my baseboard heater that heated upward. Now I have warm and toasty rooms in a matter of minutes! Because I love the two heaters so much, I plan on buying one more, in the near future, for my basement bathroom. April 22, 2014
Rated 4.0 out of 5.0 by does what we wanted after 2 weeks had a problem with the timer. called and was sent a new timer which I have to put in. October 7, 2014
Rated 4.0 out of 5.0 by could be used as 120v or 240v I used 120 on a 15amp breaker it works well as room is only 6x6 entry. the fan doesn't seem to blow very hard so it acts like a baseboard heater but it was easily installed once the wires are fed through. November 14, 2013
Rated 5.0 out of 5.0 by CKT 20 E Wall-Mounted Electric Fan Heater I'm very pleased with this product. It was easy to install - super easy. It runs quietly, heats up instantly and heats the room quickly. Small yet mighty! This product is well designed. November 14, 2013
