Morning all,
the shower was a cold one this morning as there was no hot water!!! It seems that when the heating first comes on, there is no hot water. After the heating has been on for a while and all the rads are hot, there is some hot water.
Is this something common? Could it be there diverter valve...

I'm guessing here, I'm not an engineer.
I have replaced the expansion vessel in the past (thanks to the help from you guys!) and I do have an auto air vent which I never fitted (I got it when I ordered the vessel as it was a possible for being faulty!)
