Following on from a previous topic.
I have replaced the diverter valve in my 240RSF, as rads were getting hot whilst hot water demanded, and water from taps only getting luke warm. This did not resolve the issue, and now with advice from you guys I suspect the DHW is scaled up forcing the flow to open the shutter in the diverter valve and heat the central heating instead (as diverter is only flow driven, not motorised).
I want to attempt to descale the DHW without removal (if poss) but am worried that if the diverter valve is not operating properly because of the scale how will the descaler e.g. DS40 get to circulate the DHW to work its magic?
