On a related matter, I have a filter in the heat pump which I originally cleaned annually and it never had anything to speak of in it. However more recently (in the last 12 months) it has been gathering quite a lot of what appears to be rust flakes. This requires cleaning every couple of months or trips the heat pump out on high pressure. It begs the question where this might be coming from and whether I should be adding inhibitor or something to the system.

Thoughts welcome!]]>
