alternatives to spacepak...

1. The diameter of a Spacepack duct is about 2" inside, so 1" or 1 1/4" wont move the needed air

2. The cold air going through those steel pipes would cause a lot of seating of the pipes, causing water damage.

3. The elbows in the piping would choke the airflow further.

4. How would you control having the air flow out the vents in the summer, and still guarantee the steam won't blow out the air vents in the winter. These vents would have to be fail safe to prevent turning the house into a steam shower in the winter.

5. Chances are pretty good the air would be come contaminated by old loose debris in the piping,and these contaminates would blow throughout the house.

    forgive me for being naive, but...

    Is there a reason that one-pipe steam pipes couldn't be used to transport 'cool' air from an AC unit?

    I envision a special valve at the radiator that closes the radiator, but opens another vertical pipe (maybe something telescopic in design?)

    Never heard of this being done, why can't it? Again, I know nothing about cooling with AC.

    It won't work

    A very big part of AC is air movement. In your example the pipes are too small to move enough air, the radiater wouldn't be able to transfer enough cooling energy. Systems that are out there can always be improved but what you are asking isn't workable. Sorry

    Are you suggesting using the same pipe for heat and cooling. Think of how aweful it would smell during cooling season.

    For arguments you could say high velocity, but thats not the problem with this system.

    no problem...

    thanks for an honest answer.

    I wasn't implying that the radiator itself be part of the equation. The radiator valve would have another 'take-off' with a 90 and a vertical pipe to the ceiling. (Closing the path to the radiator would open the path to the ceiling)Most of the pipes to my radiators are 1" or 1 1/4", not sure how big spacepak is, 2"?

    yes, that's my suggestion...

    My house doesn't stink from the air that comes out of the pipes on every heating cycle.

    what is?

    Blowing scale and dried crud thru out the house.
    Velocity noise of the air moving thru the small pipe.
    Finding the room in the basemant next to the boiler for the jet engine that would be required to overcome the static pressure in the pipe.
    Retrofitting your steam system to be a dual temp distribution system.
    Sounds like an exercise in futility.
