Can radiators be so close to the wall (10 - 15 mm away) That they lose heat effeciency? I am asking this because my friend wants me to install a couple more rads in his house and i am wondering is this the most energy efficient way? I know i will have to check heat output of the boiler to see if it can cope with heating up any more rads anyway but is there a better way? Getting longer brackets to bring the rads aways from the wall them adding a reflective covering to the wall behind the rads? Or will this make a difference? His heating is working in such a way that the corner furthest away from the rad in his bedroom is cold and condensation is forming on his cabinets. His loft is insulated his landlord has told him. What you do ya reckon?
1st post sorry long one

So to recap:
1. My friends wants me to add rads to the circuit i believe the boiler will not cope with. It may be a viable solution as it will at least spread heat around the room.
2. He thinks there may be problems caused by the rads already installed in the house by them being in close proximity with the wall (10 - 15mm) is it a better idea to get longer brackets and add a reflective wall covering?
