lizzie Posted April 23, 2019 Share Posted April 23, 2019 I have one of those magna clean things on my boiler. (Mains gas boiler running ufh and dhw). Man came to service boiler today and did Magna too. He said one of the cleanest he has ever seen even though ufh produces less than rads its still very clean........I am pleased!!

newhome Posted April 23, 2019 Share Posted April 23, 2019 I have one too and was surprised that when I took it apart to clean it there was pretty much nothing to clean. Link to comment Share on other sites More sharing options...
ProDave Posted April 23, 2019 Share Posted April 23, 2019 I was going to ask a related question. I have all UFH so plastic pipe and brass manifolds. All pipework is copper. ASHP has a stainless steel heat exchanger. All valcvs are brass bodies. The ONLY ferous metal at all in any of the pipework are the circulating pumps. So why is it, that the heating water, with 25% inhibitor / antrfreeze is starting to just turn a little brown in the "windows" of the flow meters on the UFH manifolds? I would have expected it to stay completely clear, with nothing (but the circulating pumps) to "rust"? Link to comment Share on other sites More sharing options...
