Baxi 105e Hot Water Scaled up HE? Any comments?

I posted a few days ago that my Baxi 105e was not heating water quick enough any more and was not getting above 40 degrees. I have now tried with tap running slowly and it does get red hot.

One suggestion from the forum is that its a scaled up HE, i dont live in a hard water area and the boiler is not even 2 years old. Does this seem acceptable?

And if so how is this remedied?

All advice appreciated.

Yes it is possible. was it onto an existing system? Was the system flushed at all?

it was fitted to an existing system (combi) and no it was not flushed.

Bigno. Yes your plate HE is probably blocked. It only takes a very small amount of debris to block approx' 24 grammes.
You could take out the HE and clean it out. Kettle descaller and a rubber hammer is a good way. let the descaller lay in the HE for a while then beat the thing with a rubber hammer. Repeat as needed. You'll be amazed how much comes out. Then go and treat yourself to a Magnaclean.
alternatively call the original installer and get them back. 2 years is not great. BUt if they didn't flush and old system I suspect they won't come back for free...........
