From the manufacturer

Sleek European surface-mounted fan heaters from Stiebel Eltron

Made in Germany

Ultra quiet fan

Even-heating down-draft design

Stand-alone or supplemental heat

Made in Germany

All CK heaters are made by us in our factory in Germany. We pride ourselves on a reputation for engineering & manufacturing excellence since 1924.

Ultra quiet fan

CK and CKT heaters have galvanized steel, squirrel cage type blowers that operate at a quiet 49.7 dB(a). The glass-reinforced poly-carbonate, radial type blower in CK Trend heaters operates at an even quieter 49 dB(a).

Even-heating down-draft design

CK and CKT heaters pull in cool room air from the top and blow warm air out the bottom. This down-draft design helps to evenly heat a space for maximum comfort.

Stand-alone or supplemental heat

CK heaters can be the sole heat source for small rooms. They can also supplement heat to a room that doesn’t get warm enough from a central source, as sometimes happens with a mini-split retrofit.

Built-in thermostat

Booster timer on CKT

Frost protection setting

CK Trend On/Off Switch

Built-in thermostat

All CK heaters have an integral thermostat for easy heat adjustment. CK and CKT heaters can be controlled by a wall thermostat in a room larger than 215 sq. ft.

Booster timer on CKT

The CKT booster timer outputs heat at maximum for up to 60 minutes. When the timer goes off, the CKT reverts to its thermostat setting, maintaining comfort at the original setting.

Frost protection setting

CK heaters have a frost protection setting. The lowest thermostat setting will maintain above freezing temperatures in an appropriately sized space.

CK Trend On/Off Switch

The CK Trend’s convenient and positive on/off switch completely shuts the heater off when it is not needed. The off position will disable the frost protection setting.

Installation notes

Installation notes

These heaters are not supplied with a cord and must be hard-wired.

CK and CKT models stick out 5“ from the wall and the CK Trend models 5⅛”.

Because these are fan heaters that blow warm air out the bottom, the recommended installation location is about 6-8” off floor, with 4” for a minimum.

All CK heaters should be mounted vertically.

Observe all installation manual precautions regarding minimum allowed clearances between the installed appliance and any hard surfaces.

Do not allow combustible materials on or near the heater.

Clean looking mounting method
4 Stars
Clean looking mounting method
Well built product, you can tell by the quality of the wiring on the inside. The design is clean and modern looking; a little larger than your standard in-wall electric heater. However, if you don't want to cut a huge hole in your wall, this heater is a great option. Just three drywall anchors and a hole for the power wiring.I mounted mine as low as I could, accounting for the 8in floor clearance, recommended by the manufacturer. With the low mounting and the bottom angled output vent, this is a great convection heater.My main reason for writing this review is to show my drywall mounting method. I recommend using a small piece of 1/2" metal conduit with a 1/2" compression fitting for the heater connection. Next, run the conduit through the drywall and use a 1/2" compression NM cable clamp on the other end, to secure your romex wire. This gives a clean look to the electrical connection, which is very visible. That is why I knocked off one star. I thought it was poor design to have the electrical cable entry at the top of the heater. It should be at the middle or bottom where it is less conspicuous.Overall this is a great heater for a permanent installation.

Reviewed in the United States on October 19, 2016
This is an excellent small room heater, but more importantly it got me lucky with my wife since she gets to toast when she gets out of the shower. The heater is well made, it works great, it's nearly silent and it's easy to install. However, the installation instructions are very sparse so you really just need to look at it and figure out how to get electricity to it. Mounting it to the wall is a no-brainer. I saw several comments about the wire showing at the top. There's a super easy solution to this issue - cut a piece of 3/4" PVC to 1-3/8" long and thread the wire through it (see attached photo). If you're really motivated, you can even paint the PVC to match the wall. Me - I was lazy and just left it white and it matches the heater perfectly. One note: this 1500 watt heater works in my bathroom, but it's on the border of being insufficient, in my large bathroom with 10' ceilings. If you have a larger bathroom or other room, you might want to consider the 2000 watt version which requires a dedicated 240v line.

5.0 out of 5 stars Heats Up Quickly & Heat Fills The Entire Room
Reviewed in Canada on June 10, 2017
I received my heater very promptly and in perfect condition. An electrician was working on the house and he installed the heater for me. I have my bedroom in the basement and it can get very cold at times. I have a portable heater but the heat does not fill the room. The Stiebel heater heats up the entire room in a very short period of time. The heat feels very comfortable and natural. The unit looks very good on the wall and its operation is quiet. I am very happy with my purchase!
