The CH51xAC series of electric heaters from VONROC are pretty stylish and can be controlled via an app or even integrated into Home Assistant. They can be mounted to the wall using the included brackets, or placed on the floor with the addition of feet. Unfortunately, these feet mean that the radiator is positioned very far from the wall.
This model provides a remedy, reducing the distance from the wall to approx. 4 cm by shortening the back part. Original screws can be used, just switch the original feet to these.
