The radiator with its relatively small output of 200 watts requires about 15 minutes, until it reaches its operating temperature of 100 ° C. The back heats up at the hottest point at about 40 ° C. Over time, the whole area is heated under the desk. However, one should not imagine that as burn under the table a fire, which can be felt clearly. The legs are warmed on "unobtrusive" way and it is now no longer a cold feeling exists.
The heating module is properly processed and painted on the front and back. The supplied hooks are stuck on the radiator side with cork, so that there are no scratches during assembly. When you first turn it smelled a little color, so we have operated him 20 minutes in ventilated bathroom. Then any color smell was gone.
For our application scenario, the expectations were fully met and we are very satisfied with the device.
