This picture shows the space I have between the freezer door and the kitchen doorway, sorry it's on it's side. But the space I have is 600mm and having looked around the web for suitable radiators, it seems I don't have much choice.
The light switch position limits the radiator height and it would look very strange if a radiator came up to a few inches below the switch.
Are there any creative solutions to get an output of around 1000watts, that will fit in the space. I have looked at 700mm regular double convectors, but 400mm wide is not enough output and 500mm will probably interfere with the freezer door.
Thanks for looking!
