Thanks for the continued support both...
The system was flushed thoroughly. Twice before the boiler was fitted and then after. The water is a always very clean, even now.
It seems odd that the noise a) started 6 months after commissioning and b) coincided with fitting the 15th rad.
I will try moving the internal return pipe once again.
No problem with the Protex - I prefer F1 anyway!
