The arrangement of the drill holes is just as already described in other reviews just a joke. I would have even laughed about it, I would not have to mount the radiator itself. At a precisely horizontal mounting is not least because really unthinkable.
In addition, it should be mentioned that this heater can not be easily adapted to structural conditions. According to the manual so many mounting variants are safety forbidden that in our case was ultimately no "legitimate" mounting possibility more.
Finally, however, is still mentioned that the heater but of its essential purpose quite well: He shines within a short time a comforting warmth.
Nevertheless, the product has too many shortcomings to recommend it with a clear conscience can.
