Hi
We've recently had an issue where our hot water was fluctuating hot to warm and occasionally cold. We got a Britsh Gas engineer out and he changed the heat exchange plate but noted that the main heat exchange had sediment in it also and said it would need replacing or maybe even just buy a new boiler.
That said, when he left we had hot water and it was perfectly fine for showering etc.
Two days ago we had a total loss of hot water, we've since had another engineer out via our home insurance. I told him all the above and he's just put it down to the same. I regret telling him now as I feel it would have been better for him to form is own opinion without my help.
I know it's idiotic to doubt the advice of two trained professionals but here's whats bothering me.
1) The heating is rock solid, it gets up to temp and stays there no obvious signs of any issue.
2) Would a blockage like they describe just go from the hot water working inefficiently to completely not working at all, especially given the plate exchange has been changed?
3) The boiler (Glow Worm Betacom 24) is giving an F23 error (Maximum temperature difference reached between return and flow heating) water circulation fault.
Before I pull the trigger on a new boiler could anyone offer a 3rd opinion on whether it does sound like its just build up in the main heat exchange that's causing this
Cheers
