ravenheat combi boiler

[jim.nicholson]

have a relatively new ravenheat combi boiler and my problem is with hot water. On occasions it runs hot briefly then goes cold, and on other occasions it works perfectly. C.H works perfectly. Would appreciate any obvious solutions.

Thanks

You dont quote the model or what you consider to be "relatively new".

Sounds like a diverter valve problem!
