Hot Water running just warm...

[Underwater]

I have an Isar HE 30 which was installed in July. 2 weeks ago hot water was working fine but heating was not working. Had system power flushed and heating fine now. Problem is hot water is just warm at max. Anybody have any ideas?

Cheers.

sounds like the plate heat exchanger needs flushing out as well it will prob need taking out to clean out i have done a few and they do get rather blocked with debris and sludge or just replace it wih a new one and then use some sort of inhibitor

Has it got a 3-way valve? It can normally be adjusted with a screw.
