In a small residential system, use adjustable vents. The easiest way I've found to balance the system is to set all the vents approx. half way open and run the system for a day or two. If the room is cool, open the vent a little, if hot, close it down a little. Done is small increments, you should have the system balanced very little time.

Another question about replacing air vents

I'm no kind of engineer, but I do have a single-pipe system in need of some tune-up, as it's been neglected for some years. So I thought it would be prudent to replace the air vents (a miscellaneous collection). Having attempted to grasp some of the principles of venting by reading Dan's book, I'm faced with the fact that both Gorton and Varivalve seem to endorse what Dan called the "geographical" approach: bigger vents the further away from the boiler, rather than basing the vent size on the size of the radiator.
So should I ignore (reverse, even) Gorton's advice and put #6 vents on the first floor and #5s on the 2nd floor? Or get Varivalves and adjust them in a like manner? And if the latter, how do I arrive at the correct setting?
Thansk for any suggestions, and forgive the naivete.

Steamhead (in transit)

Before you do that

have you checked your main vents yet? Look at the ends of your steam mains to find them. Measure each steam main's length and diameter and tell us what vent is on them.

Once the main vents are right, balancing the system should be very easy.
