Advice being sought. I've been asked to price up a new heating system for a local village hall. At the moment they have high wall mounted panels that don't work too well. (the committee that run the hall say half of them don't work anyway) I picked up a brochure from the wholesalers for Rointe Kyros radiators. Anyone had experience with these and are they as efficient as the brochure makes out? The hall is in a rural village, no gas or oil tank.
