Heating comes on, but no hot water

[wyleong]

I am currently experiencing no hot water coming out of my taps, but my heating still comes on at the right time. Everytime I manually switch on my heating, the fire won't light up and no water is heated. Someone suggested bleeding the radiators, but what should I do? Thank you!

I had this problem earlier this year and heating on everytime I needed hot water.  Basically ending up forking out for a new boiler.  Plumber said that he could mend the old one but in the long run would need continually repairing and would be more cost effective to get a new one.
