Lovely designer towel radiator. Quite heavy so make sure its attached to something solid.
My only gripe, and its nothing to do with the radiator, is with the T-pieces for converting to dual fuel. In my experience (limited) once they have been fully screwed home they never point in the correct direction. What I usually have to do is put as much PTFE tape on the threads as possible to try and increase the resistance to turning so that it doesn't move if knocked or during connection to the central heating.
I think a better option would be a selection of different thickness fibre washers to choose from that could be fitted between the o-ring and the radiator to allow fine adjustment of the final position and ensuring a tight joint.
Rant over.
