the things above your boiler are auto air vents , make sure the caps are
not screwed down tight , or the air wont get out ,
Auto air vents are for filling/commissioning purposes only. Once the system
is free of air the tops are to be screwed down. Combi instructions
actually state this a smost have integrated. When the auto air vent is open
hydrogen from internal corrosion may escape. If there is hydrogen in the
sytem it will make the tops of rads cold, and that is a sign that the system
requires proper attention not just releasing it and refilling.
thats all very well and good , but that isn't a combi boiler .
