Hi
Just a quick note to say fault was with diverter valve after checking all feeds were being sent when C/H and hot water were being called for the valve was not switching . Replaced valve all working correctly. Thanks piccasso you just made me dig a little deeper and think more methodically...
Thanks for quick response .
System has a Drayton Digistat +2 programmable room stat.
Wired to the system is a dual channel Dual Channel Drayton Lifestyle LP241 programmer which has a function to switch independently both C/H and Hot water.
It is this programmer I have used to fire up system...
Hi hope someone may be able to help.
Have Greenstar 30CDi boiler hot water functioning fine but on firing up central heating it does not flame up at all ( sorry if thats a poor description.)
The controller for the unit is hard wired and can override the room thermostat controller so the fault...
Just checked tanks all okay did forget to say on original post that there is some warmth in radiators but it is very minimal ,dont know if this helps diagnosis.
I have glowworm 55f boiler with potterton EP2000 controller switch .The radiators all have microbore pipework.
The central heating fires for about 1 minute and then cuts out.
System worked when we moved in 2 months ago,since then I have had to shut off the hot water from the main hot water...
