Need help balancing my system!
just replaced radiators on first floor with "cast ray" radiators and thermostat is on first floor, second floor has 38" tall column radiators, when thermostat is satisfied 2nd floor is still cold! so what would be a better solution:
1. put gorton #D on the upstairs radiators and #4 and #5 downstairs, or
2. put vents on the top of the 2nd floor risers and leave the radiators with small vents
in other words whats better venting the risers or the radiators??
