in THE MAIN WALL
I took 2 radiators out today that a have twice the sections I need for my porches I enclosed. Do you think I can control the output with slow venting?

    control the output

    yes, with slow venting, and that old persian carpet [from one of your many foreign jobs} over the top of the radiator, it will be reduced in output, and just right. if not then turn the vent upside down.--nbc

    Throw a TRV on it....

    TRV

    These Radiators are small ones with 1" connections. I have 9; 3/4 valves I was going to use to convert to hot water before I met Dan. Do you think they would work reducing down at the radiator or am I asking for trouble that way?

    If this is 1 pipe...

    which you imply from the venting question, in my humble opinion the 3/4" inlet valves may cause trouble from condensate not being able to get back out as the steam is going in.  Gurgle gurgle... maybe even hammer... possibly poor heating.

    Thinking

    Jamie: That's what I was thinking. I have seen radiators working on 3/4 lines. But I need to consider that the valve is going to close and that probably will trap condensate. So what will happen when it opens probably (bang, bang).

       I was wondering if anyone tried it and if it worked,

    Does my memory serve me right is there a thermostatic valve that goes on the vent side.

       Trying to use up what I have may be more costly that what it is worth.

    After I ask the question the Danfoss sight comes up. Probably the best route is pipe them right and get the right valve. Then I can have heat there if I want or turn them off with out trapping condensate.

       Thanks for the sounding board help.
