I have a pumped open vent CH system suppling hot water and heat to 9 rads.
My problem is that I am constantly venting air from the upstairs rads (daily)
I have recently change the boiler to a Ideal Icos HE18. Air still getting in system!
I have changed the pump. Air still getting in system!
I have cleaned the system. Air still getting in system!
I have checked the complete system of leaks. there are none.
All the above need to be changed anyway and I hoped that these replacements would resolve air problem, but didn't.
I have no idea what to do next. Can anybody suggest answer to this problem
