I doubt it will be the diverter valve, as the diverter valve diverts the heating AWAY from the heat exchanger and lets the water through.

See if you can see a thermostat anywhere for the heating

hi marky there should be two swithces one marked heating or with a picture of a radiator and one marked hot water with picture of a tap on it they will be either by the main control panel or part of the timers for each.

If you have the heating on then the heat exchager is already hot so you get instant hot water. If the heating isn't on then it can take up to a minute to get really hot water from the tap. Are sure that you waited long enough ??

yep.. waited a couple of minutes no luck... oh well guess I would be £100 out of pocket... :(
if its a brand new house and a brand new boiler, it will be covered under the warranty. If they are still building you can get the builder round

I know this isnt going to be much help when I cant think what the part is called , but if you look at the pipe work when you have the cover off look where you have electrical connections attached to a component that actually sits inside of the pipe work , this is the component that sound like is causing you the problem as when you draw water this thermostat control isnt firing up the boiler .


Hope you can understand that lol

still no luck !! when I turn it AUTO or position "I" it works fine, ie both the hot water and heating.. and burner comes on..

however, when I just want hot water and turn it to "O".. the burner doesnt come on...

perhaps, these settings are generic.. the O, Auto and I... any one got an idea..

please help guys.. dont want to pay £185 for something stupid

we have a combi (baxi) it has a 3 position switch with

position 1 with an icon of a tap and a rad
position 2 with an icon O this is off
position 3 with an icon of a tap

if its a brand new house then as said by others either the builder should do it or boiler manafacture should do it foc.
