Hi all

Having looked at the FAQ for answers I have become confused and would
like clarification on the above matter.
Some rads are hot - Do I close up the lockshield valve more on these
rads?
Some rads are warm - Do I open up the lockshield valve more on these
rads?

I noticed some talk of pump speeds also. I have a sealed system with a
combi - (Vokera 80 Excel SP) can I regulate pump speeds with this?

Cheers
