Hi
I have a vaillant combi.
Central heating is working fine.
If I put a tap on for hot water the boiler fires up but only delivers luke warm water.
If I leave the tap on (tap A) and then go and turn on another tap in the house (tap B), then tap A delivers proper hot water!

Any ideas at all?
 
Hi Tom

only started yesterday....taps have not been changed for years...in fact nothing has change.
No leaks anywhere, pressure is fine on boiler (1.2bar)...
Boiler is a Turbomax
