Hi all,
I have a Worcester Bosch 24cdi. Earlier on this year I had the hot ware heat exchanger replaced, I honestly can't remember the problem now, but it was freezing cold, the boiler wasn't working, and we had plumbers on site already due to other building works, so I just let them get on with it!
Towards the end of the building project, we finally got our kitchen back and I noticed there was a definite drop in the hot water flow rate (or maybe pressure?). Basically, before I would get bubbles when filling a bowl of hot water to do the dishes, and now I don't.
I borrowed a weir cup and measured the HW flow at 7lpm. I didn't measure the cold (which was stupid), but basically it comes out like a rocket!
The only thing that has changed since then is that I've had the lead pipe coming into my property replaced, so the cold water flow rate will have increased. Could this cause the problem?
Finally, just in case it's relevant, I've also recently changed the diaphram on the diverter. This did not affect the flow rate at all, but did give me a chance to check the flow rate reducer on the heat exchanger, which seemed fine to me.
So...any ideas on what the problem is, and how to fix it?
Thanks!
Leon
