I have read about a central heating system being balanced. I recently
removed all radiators to flush the gunge out of them. Whilst doing
this I had to close both sides of the radiator valves. Upon rehanging
the radiators I have opened fully the valve on the opposite side to
the thermostatic valve, ie the water inflow to the radiator. How
should these inflow valves be set as i have radiators over 3 floors
with 2 on the bottom, 4 on the 1st, and 2 on the 2nd. Any advice
greatly appreciated in getting the balance back.
