steam heat

does anyone have experience with one pipe steam system?
I seam to remember my steam instructor mentioning that it is very inefficient and he was glad to get rid of it.
What kind of efficiency can one expect from this kind of system?

I think you may be asking about a monotobe steam generator. They a special case of a once thru steam generator.
Check in the main area. There are lots of threads on them. Their main problem is controling them.

Do you mean the system where the steam enters the radiator from the same pipe the condensate returns ?

No it generates steam not condense it. Sorry thought were asking about boilers.

Yup I've worked with single pipe heating systems. What do you want to know about em? They are just as efficient as two pipe systems as far as getting heat into a building. Two pipes are much more expensive and twice the radiating area so it depends on how much building is to be heated by the mains.
