Why do I have to have central heating on to get hot water

The cylinder stat controls the temp of the hot water and when the stat makes demanding hot water it supplies the pump and the boiler.Plus if u have a three port mid pos diverter valve it could be stuck in the heating only position.

Could be if it is an older boiler that the header tank is dry in the loft.On water only the boiler will only stay lit for a very short time but when the rads are on the pump will pump the existing water around the system leaving the boiler on long enough to get some hot water.t
