I have a ground floor flat that uses a servowarm system to do the central heating only. There are 3 rads(lounge, bathroom and bedroom.) The lounge rad gets very hot as it's first in line but the others do not ! I have put fernox in the system 2 weeks ago but it hasn't improved. The feed pipes to the other rads do get very hot but there is basically no flow through them. I suspect a problem / blockage with the return ? I have the balance on the lounge rad only 1/4 turn open so it doesn't steal all the hot water and the valves fully open on the others..
The pump is on max so it should fly around ? Please helpppp !!!!
