Turning the what now?
My boiler is ancient and there is only a heat dial. I know how to top up the boiler when the pressure dips, though where does the water go when that happens?

Balance the rads? You what?

Central heating has a circulator (pump) to circulate the warm water round yer arse.
Circulator has 3 settings.
Too fast and it'll make noises.
You've got 2 valves on each rad, one at each end.
One is the TRV, opens and closes on demand.
Other is lock-shield valve, should be set by plumber to ensure equal flow through all rads.
Water is a lazy cunt and will find easiest route through system.
