That is my main concern, though I think you can get low surface temp rads (not done much investigating yet). Can't do under-floor for a few reasons: wet too costly to install (would need to dig out considerably); electric too expensive to run (based on the experience of a number of friends); and don't want to raise the floor so that new tiles will stay level with existing parquet.
