Any help with radiators?

[lathany]

Does anyone have any useful tips on calibrating radiators?

Our house has a crap complex pipe structure for heating with various sets of radiators running on various different loops and we thought we would try and calibrate them all this evening to try and get something resembling an even heating effect throughout the house. Any tips on which radiators to start with (we also have some idea of where the loops start, although not completely) would be met with gratitude!
