I have Worscester bosch 350 combi boiler. Every few days I have to bleed air from my towel radiator. How is air getting in when system is pressurised to 1.4Bar?
thanks for your response. I have been bleeding system for ages, just cant help thinking there must be a problem. My daughter has combi central heating and doesnt need to bleed at all.

The process of heating water releases gasses contained within it H2O - once released the gasses will not spontaneously reform and become water again.

Air will trap in the system and will still pressurise so I don't see you logic on this one.keep bleeding the rad and topping up the system as needed
