Sorry Mark, I put the wrong name on this last reply.
I put yours instead of mine.

: Mark,

: I have a Honeywell Thermostatic Radiator Valve Model T104A / V110F (Valve body) on one of my Radiators located in a mid sized bedroom and it works very well. However, I have a two pipe system. In a one pipe system you can not regulate the steam flow because the same pipe is used to return the condensate back to the boiler. If a valve was placed on that pipe and throttled back, I imagine the condensate would simply fill the radiator after a while and squirt out the vent.

: Since I don't have to much experience with a one pipe system I am speaking strictly from reasoning and what I have read. Perhaps someone else can verify what I am saying.

: Second point. Take a close look at your vents on the radiators. Some of the larger radiators may require the addition of another vent to do the job. Also, make sure all are working correctly. In theory, if everything is vented correctly, all radiators would be the same temp at about the same time provided the rest of the system is set up correctly.

: It describes in enough detail the physics involved in steam systems.

: Also look at A very good site.

: Hope this helps.
