What is this thing?


The simplest steam heating system is the
Single Pipe Steam System with Main Pipes Pitched Towards the Boiler


Steam and condensate use the same main pipes. The condensate flows in the opposite direction of the steam.
Air valves are necessary for evacuating air during start-up.
The system is simple but the heat emission in radiators or in heat exchangers are hard to control. Modulating the heat will cause the heating elements to be partly filled with air. The system can work properly in applications where the heat can be modulated directly in the boiler, as applications for warehouses, garages and so on. The system should be avoided where it is necessary to individually modulate each radiator or heat exchanger.
The condensate draines back to the boiler and during stops the system fills with air. This makes the design suitable for temporarily heated application working under water freezing conditions.

Sorry, but I just read this post. To back-track for a minute..... ARE YOU SERIOUS?? I do not mean to insult the original poster, but who doesn't know what a radiator is?? Were you raised in the forest by wolves or something? I think this post was a joke. If not, I am sorry.

p.s., that bright shiny thing in the sky is the Sun.....

I see you can find schematics, too bad the info is incorrect. Both 2 pipe and 1 pipe steam should run at a couple of pounds of steam. pipe sizes are bigger on 1 pipe than 2, for obvious reasons. BOTH systems let air in at the end of a cycle but while its easy to see on a 1 pipe system because the vents are on each rad, the 2 pipe system venst are on the mains, with the heating unit. Properly maintained, there will be minimal difference between the two.
Here's a link to explain how TRV's work on 1 pipe steam

And you apparently know everything about everything? I"ve never lived in a home with a radiator, and yes I know what one is. And I also know what a smart is.

very entertaining reading!....steam sucks.. that's why most have gone with hot water which can be much better controlled via regulating valves and outdoor reset controls to vary system water temp...Steam is always above 212 deg F!!...so much for control..no thanks!
