Unfortunately, this product is not IP24.

Hello. 1. the noise of the device is quite disturbing, especially the wobbling when it oscillates. I do not have a DB meter, it is a subjective measure. 2. The fan should stop when the temperature is reached, but this was never the case with us. But the fan has 3 speeds.

Unfortunately not. The item is not intended to be placed against the wall. In fact, the manufacturer advises leaving at least 50 cm of free space around the item when in use.

I don't think the radiator has a timer function, but if in doubt, I would ask the manufacturer Blaupunkt: https://www.blaupunkt.com/de/nc/produkte/haus/heizluefter/products/single/18622/
