I have just drained the CH system and fitted a new drain radiator valve. I have re filled the system, bleed all the radiators however they are not gettin hot. I have changed the boiler control to constant.
I have just tried running the hot tap, however this is also cold, although the setting is on constant for water.
I cannot hear the boiler turning itself on, when I change these settings.
What should I do?
