Hello everyone. This looks to be a great forum.
I'm desperate for help and hopeful of finding it here.
My CH and DHW system was originally served by a Baxi Bermuda, replaced in December 2005 by Glow-worm 24hxi Boiler. Open Vented 2-valve System, with indirect HW Cylinder, 11-rads (10 with stats) and a skirting heating installation, with stat.
System worked fine until recently when boiler appears to ‘cycle’ more than usual, taking much longer to bring rooms and DHW up to desired temperature, and frequently ‘banging’ (kettling?) before boiler shuts down at around 74-deg C, remaining off as boiler temperature slowly drops and then repeating the cycle.
Installation company suspected possible ‘sludge’ in system and have carried out ‘powerflush’ through all radiators and boiler but this hasn’t cured the problem.
Any ideas as to what could be causing the problem?
Note, it occurs when running either just the DHW system, the CH system, or both.
I believe my 24hxi boiler was an early version – is this a known fault with this model perhaps?
Don’t know where to go from here. Any thoughts and advice greatly appreciated.
