i have had my alpha cb28x for just over 3 years now but the hot water does not work unless the heating is on, is this a common fault and is it expensive to repair,
hope someone can help....
cheers
 
sounds like the diverter.
not sure about your model, but older ones known to fail
 
Do a search on alpha cb24, diverter, diaphragm. Stacks here.
 
Check the dhw microswitch, it sits clipped onto the DV assembly, just to the left on top.
