Have a problem I was hoping for some advice on. I have added another radiator to an open vent system, and finding that I can't get them to all heat up at the same time, even after balanching them. Turning any one of the larger radiators off makes the rest of them hot, but can't seem to work out the best way of resolving this for all of them together.
I don't have access to a radiator temperature sensor, but the way I have balanced them is to turn all the lockshields off, and then slowly turn them back on util each radiator is on. The air has been purged from each of the radiators.
I was thinking of upgrading the pump if balancing doesn't fix it, but not sure if that would make much of a difference in an open vent system (header tank is in the loft).
System comprises of 8 radiators and the pump is a grundfos 15/50
Cheers
