My UF heating pipes were filled with simply water 4 years ago. It is very unlikely that the system will ever see freezing temperatures, so I reasoned normal tapwater would be ok. The only problem is that it has turned a bit brown and I cannot now see though the plastic flowmeters so as to balance the flows between zones.

Filling these pipes was very awkward - air locks - so I am a bit reluctant to drain the water out. Is there anything I can add to the water(I can do this via the buffer tank, draining some water off if necessary) so as the clear it?

Not as far as I know, once the water has gone brown that's it, I would just dose it with some kind of corrosion inhibitor and forget those silly flowmeters. Can you ditch the feed and expansion tank and convert to a sealed system?

No, not really. I've done a lot of Heath Robinsons in my 70 years and I can't face messing with this system again. But it is fairly reassuring about the brown water - I thought it was maybe something to worry about.
