called to a radiator thats whistling,
on first arrival not a peep, but every 10 minutes or so, sure enough it started whistling, not your normal whistling radiator noise this is a proper mild singing!
2 pipe system, flow top right (trv), return bottom left.
changed trv settings, changed lockshield settings.. still the occasional whistle!
changed pump speed settings. no change
reduced pressure in system. no change
increased pressure in sytem. no change
pipes are 1/2 screwed iron dropping from ceiling run of 3/4
the occasional noise, does seem to be louder in the ceiling space
no changes in the installation for several months.
anyone had anything similar, if so what was the cause. at the moment think my next step is to isolate 1/2 inch pipework drop and check it is the rad pipework.
got meself a head scratcher... and a first
ta.
