Hello, im new to the forum and tried to search for a relevant thread, however only error message! So forgive me starting a new thread! I have a heating system utilising microbore and associated manifolds. I would like to replace one radiator with a single zone underfloor heating system. Can this be done as a direct replacement? (naturally I require the appropriate valve/pump/stat). I am more concerned with the fact I have a microbore system. All UFH suppliers do not state in words or diagrams connection to microbore system! Thanks for any help.
