Over the weekend, I drained our central heating, removed a radiator (that had previously been closed off), and refilled. Since then, our hot water gets nowhere near the temperature it used to. (too cold to shower comfortably).
We have pumped central heating, and a gravity fed hot water cylinder. The boiler is heating water fine, and the hot pipe into the hot water tank is very hot, but the out pipe doesn't even get warm. It's like the water in the boiler/cylinder loop isn't circulating (or at least not circulating properly). The header tank for the boiler and heating is completely full, and I don't see how there can be any air locks in the boiler/cylinder loop as the tank seems to fill at the highest point so it seemed to me that any air would escape back up to the tank. That said, there's definitely something wrong somewhere :-/
For what it's worth, my radiator bleeding key snapped, so i've not been able to bleed the radiators yet, and i can hear there's air in there. I'll be doing that asap, but aside from that, is there anything obvious I need to try to get the boiler/cylinder loop flowing again? I just can't see why it's not circulating! (assuming that is actually the problem).
Cheers for any advice
