    Air in system/oveflow problem

    Thank you very much again. It's been suggested, as an alternative to combining the feed and vent pipes, to install an air separator. Will this help?

    Air in system/oveflow problem

    Thank you very much. I'll try, but I'm not sure they know better. I was considering buying that HomeCare heating system insurance from British Gas and asking them to come and fix it, as they won't send an engineer without buying the policy.

    Air in system/oveflow problem

    Hello! I have an open vented system. The boiler is new (classic condensing). The pump is new. Everytime the pump starts, air gets into the system (a lot of air). I could let the air out of the first radiator every half an hour! That happens at the lowest speed on the pump. If I put the pump...
