All 4 radiators ground floor is not heating, but all radiators upstairs is working fine.
All 4 radiators bled, flushed, removed and cleaned.
After all the line cleaned, flushed and bled the initial re-installation of the cleaned radiators the hot water flows in but after 5 minutes it seems like the cold water has strong flow as it cools back again the radiator and it stays cold.
I'm assuming that my heating system is conventional heating system (looking into your schematic diagram) the only difference is the hot water tank is located ground floor.
Please help.
Thanks,
Rolando
