I have never used a combi biasi boiler, and need to know whether all the on/off taps need to be turned before you can use it, I appear to have hot water to the taps and shower without them being turned on

if the taps where of u wouldnt get water out the taps or any water out the hot taps a combi boiler woks like this when u have the heating on it works and when u open a hot water point ie tap or shower the hot water function works stoping the heating and if u have the heating of as soon as u open a hot water point the automatically comes on if its working fine best to leave it alone.
