so this type of conversion is no longer possible. It really didn't work that well anyway, unless you were burning coal.

Creating Vapor System
I was reading one of the old articles posted on the Library titled "Six Kinds of Steam Heat" (Plumbing & Heating Business, 1941) which describes One Pipe Vapor systems. The article says:
"By simply installing vacuum air valves on the radiators of a one-pipe gravity steam system, the characetristics of the system are changed and during the 'off' period, it acquires some of the characteristics of a two-pipe vapor system."
The article goes on to describe the benefits of such as that of longer radiator heat retention and lower fuel bills
SO my question is, is that all there is to it?? I understand you would need to know more specific details of my particular system, but just HYPOTHETICALLY, could the simple replacement of all of my current radiator air vents with "vacuum air valves" (and I am also assuming the change-out of the pressuretrol to a vaporstat with a correspondingly lower cut out setting) result in longer radiator heat retention and lower fuel bills?? If so, I am tempted to try it (even though the current system works fine). My system is otherwise tight, no leaks, no drips, no loss of water, so I think my pipes would be able to hold a vacuum.
One the other hand, the article opens by talking about the various misconceptions regarding steam systems proffered due to the carrying forward of old or out-dated information. So, in that regard, is this 1941 article no longer accurate in what they have just described? I am curious what the experts think before I spend money on vacuum air valves or end up creating some new problem.0 -

Steamhead, Hofmann still has them in thier catalog,
You would need a modulating gas train on the boiler, as Noel has seen, i believe to make this work nicely. If you want to try something else to improve steam efficiency, why not put in a Paul system using the steam to power a Moline type (venturi) air ejector to pull the air out of the system rapidly.
I wish I had some systems to try this stuff on, not many are available for experimentation.

Yeah Dave
your the mad steam scientist!
Tell me how is it going with the steam systems that are sized to the heat loss rather than the connected load? Haven't heard from you in a while on this.

Robert

Thanks
Thanks for the advice gentlemen. I will stick with what I have now.0 -
Just the #76
or the #2A as well? I thought they stopped making the #2A vacuum vent for radiators at least ten years ago.

If your fuel bills are high
check for missing, too-small or stuck main vents, also lack of pipe insulation and too-high pressure settings.

My mistake

There's literature about these
in the Library if you'd like to see how they worked. It's in the Steam Heating section.Retired and loving it.0
