I am going to balance my radiators this weekend, I just want to check some
facts that hopefully some of you can help me with.

I need to open up all the control and LSVs and find out what the flow is and
find the index radiator. As I understand it the control valve should be
where the flow is in and the LSV on the outflow. Two of my radiators appear
to the the other way round - is it a simple matter of just swapping over the
knob from the control valve and putting it on the LSV?

Do I leave the index radiator fully open and work back to the boiler or do I
start from the radiator closest to the boiler?

From what I understand I might have to adjust the speed of the pump. I have
no idea how to do that! I have a Potterton Puma 100 boiler and I can't even
see a pump let alone adjust the speed! I understand that some boilers have
automatic pumps - is that right? Does my boiler have one?

Is it correct that the drop needs to be 20 deg F?

TIA
