Hi all,
I have a pumped two valve system. When the boiler first fires up and both valves open, both heating and hot water get hot OK but there is loads of air rushing around the tank heating circuit ?. You can hear it going through the pump and bubbling through the tank ?. I cant understand why the air does not also get into the rads circuit ?. There is a 22mm vent pipe and 15mm cold feed in the common feed to the pump. Can air just get stuck in the tank heating circuit ? if so how do I get it out ?. No bleed valves evident.
Many thanks
Graham.
