I have just changed a radiator, filled the system back up and found that the central heating is not working. The central heating Flow and returns have been split into 2 curcuits, 1 is working great, the other does not warm all the radiators, and the rad I have changed is now only getting luke warm, this rad is the last 1 on the curcuit. I have tried closing all the other 3 rads so that the last rad gets the hot water, but this did not work.
Any suggestions would be much appreciated.
