The hot water never gets piping hot but if the central heating is running
too, the radiators are almost too hot to touch and the hot water gets that
way too. Is this the diverter valve at fault - do I need a man in? What
else might it be?

What make / model of boiler?

What power output?

Does the boiler fire up and keep running if you use just the hot water?

Does the temperature increase if you reduce the flow rate?

Bonus question, if you keep the hot water running does the rad circuit
heat up? (feeling the flow pipe out of the boiler should tell you).

I will check and report - it is my nephew's boiler at the other side of the
city.
