Vents on 2 Pipe System

Howdy Gents -



1st time post for me. We bought an old century home in Columbus, OH. 10K sq ft, 2 pipe steam heat system with 30 radiators. My question - can I use air vents on this system? The steam traps appear to be working properly, but I'd like some of the radiators to heat faster than others.



Thanks,

Ben

    2-pipe problems

    Don't put vents on the radiators, as they were not designed to work that way. There must be some reason for any non-heating radiator. Have you checked the traps, thermostat location, main venting, and pressure. If the pressure is too high (sometimes more than 6 ounces!!!), the traps may not be able to do their job.--NBC

    its probably more likely

    you have a steam distribution issue than an air vent issue.

    with 2 pipe

    You can use the supply valves to throttle the radiators you don't want as much heat at. You should look into getting some books and reading up on steam, with a system that large I'm sure you'll have more questions. Take a look at these http://www.heatinghelp.com/products/Super-Deals/14/129/A-Steamy-Deal

    I'm just a homeowner, and these are very readable and immensely helpful. If you can, take some pics of the boiler, and near boiler piping from as far back as you can, and any unusual looking things attached to the piping.

    Post pics please

    Do you know what kind of system you have?

    Please post pics of some of the radiators, inlet valves, outlet traps, boiler, other devices in the boiler room, etc.

    You don't indicate that there is anything wrong with the system, but that you want some of the radiators to heat faster than the rest.  Are you saying that they already head evenly?

    If you are trying to create a warm spot in your house, you could partially close all of the inlet valves except for the radiators that you want to heat fast.  It would be a trial and error process, but it would probably work. 

    We really need pics and more information to advise.
