The temperature did rise eventually. i'm confused; I didn't think the water for the rads came from the hot water cylinder. I thought it was only water for taps that came from the hot water cylinder...
The unit has a cylinder, with another hot water cylinder wrapped round it (double-jacket).
If I'm right in remembering, the inner cylinder feeds water for the radiators, the outer one is your domestic hot water store.
