Hi Meri, our architect has come back to us - they spoke to a mechanical consultant and do not recommend the system for the following reasons:
The skirting is metal, quite large and considered generally as quite unattractive.
It causes staining to the walls in time because of the constant flow of hot air up the wall.
It is difficult to fit neatly to walls especially if the walls are uneven or have junctions which are not 90 deg.
You have to keep furniture away from the walls for the system to work.
It may well be more suitable for your house, our building is very old and I don't think there is one 90 deg wall in the place! The other points were news to us and very useful. Hope this helps
