Hi all...
Over the past few weeks the hot water from our 12 year old Vaillant 242 boiler has been fluctuating... as far as I can see the central heating temperature is fine.
In April 2005 the original "red" heat exchanger was leaking and was replaced with a smaller rectangular chromed unit, this came with a 1 year parts and labour warranty and 5 years anti-scale.
Searching the forums I have also found this //www.diynot.com/forums/viewtopic.php?t=12887 so wonder if the new heat exchanger is scaled up.
That said the water flow seems to be the same as it ever was and I have not noticed any sludge or rust deposits in the water.
The water temperature varys from hot (not scalding) to lukewarm so it is proving difficult to wash, bath or shower. For years the temp. adjusting dial has been scaled up so we can not change that. Back in 2005 I asked my plumber about this and he said... if it isn't causing a problem then leave it as they are prone to scaling up anyway - could this be the cause of the problem?
I can hear the boiler fire up heat some water and the switch off again, and then it starts again maybe ten seconds later - rather than staying constant, so I wondered if a sensor could be faulty.
If it is unlikely to be anything major then I'd fix it myself... problem is I don't know anything about boilers... We are also moving in a few weeks so I am loathed to spend 100's on it now
Any suggestions on what you think the problem may be please?
Many thanks
