Can anyone help.....
I've just drained the central heating system, which is an open vented fully pumped system, so that I could add inhibitor and boiler noise reduction concentrate to it. However, when I came to refill the system it would not fill up, even though the header tank is full ... I've tried opening all the bleed valves to let any air out, and even opened the drain of tap at the lowest point, but no water flows out or through the system
boiler is a Potterton 30e
Any help gratefully received, the house is freezing!!!
