Can anybody please advise to the likely cause of the following problem on my Worcester 350 Combi boiler?
The central heating sideof the boiler works fine but there is no hot water (may get a bit of lukewarm at beginning).
The boiler does not ignite when demand for hot water is initiated (demand light does come on though).
The boiler also goes out when central heating is on if hot water tap is turned on.
Is it possible that it is just a faulty hot water overheat thermostat?
Thanks
