Hi
I'm so sorry if this has been asked before. I did a bit of a search but came up with nothing exactly like this.
When I turn on a hot tap I get the store of nice hot water.
The boiler IS firing up, I have replaced the diverter valve diaphragm previously when it wasn't firing up. It was working fine for a while.
The thing is, even though the boiler is firing up the stream of water goes warm then cool after the initial preheated store.
The radiators aren't getting hot when I run the DHW so no worries there, again a problem I have fixed before.
The CH is working fine.
The boiler does lose pressure but then it always has! I have replaced the PRV previously too. I've been so disappointed with this thing! The installer is not around anymore it would seem. I have to keep topping up the pressure but the DHW problem persists regardless of the current pressure.
I hope that is all the info you need to suggest something.
Thanks very much
Terry
