Hello,
Relatively new to this forum - did post on here a couple of months ago when I had a faulty thermostatic valve on my hot water cylinder.
Except for the aforementioned thermostatic valve, the system has been running fine for over a year (since I moved in) and has been reliable for what can only be described as an old system.
Anyway, I have an Ideal Classic boiler, Grundofs Selectric Pump, Myson Aerjec (all shown in the attached picture).
Like I say up until a day ago the system has been running smoothly. Then all of a sudden last night I heard a deep rumbling sound, gradually increasing in volume and then some serious rumbling in the pipes in the cupboard containing the cylinder, which ceased when the boiler shut down.
Upon further investigation this afternoon, this rumbling/rattling culminated in an ejection of dirty brown water and a gush of steam out of the vent pipe into the f/e tank.
The pump seams to be working fine and continues to work after the boiler cuts out, so I don't think this is a faulty pump issue.
I've seen 'Kettling' mentioned on other threads but don't really know what 'kettling' means.
Could this steam be caused by limescale buildup? Or a buildup of sediment in the boiler? I'm in London, so i'm gessing limescale could cause a problem.
Can anyone give any helpful suggestions?
Much appreciated.
