Thank you for all your comments
However after doing some more research i checked the venturi over the fan
which i believe fluffs up and is a common problem on this boiler.
It did in fact have salt crystals in it which i then cleaned off! i think this was probably affecting the air...
Hi
I have a problem with my Halstead Finest Gold boiler.
The CH works fine although at the moment it is turned off (summer)
The Hot Water when demanded gets hot but then the saftey lockout LED comes on and obviously the water temp reduces back to cold.
I have tried reducing...
