hi there
its a biasi garda 24 combi water pressure is 1.5 ,hot water running fine but when i put the heating on its not gonna work (this is a new boiler) if any body know what the problem is
Could be lots of different things. Unless you feel like investigating it in more detail (see other threads for examples, or check the manual!) you'll need a heating engineer. Agile (see his profile) covers parts of London and is very good (or so he says).
If a new installation have you understood the time controller? Press left hand buttom until it syas on in top right, and have you installed room stat properly. I don't know this model but most likely there is a jumper to be replaces by room stat. Try puting jumper back, does it now fire?
Beyond that get a corgi engineer like Agile to it.
