My Vaillant combi boiler fires up on central heating and heating is ok but the boiler will not fire up when opening sink or bath taps for hot water, what could the problem be ?
Carefree suggested the problem was I hadn't mentioned the model number and other relevent information, well I've mentioned it now and still I have no hot water.

I have now added the model numbers and letters but the problem still persists, may be I should try adding the colour of the boiler, that might cure it.

"what could the problem be ?"
It could be you haven't mentioned the model, or any other relevant information.
