heating issues with my steam boiler new radiators

hi there, had two new radiators installed in one of my rooms. the boiler does have the capacity for them. the original guy changed the orphaces initially before knowing we would install new radiators… not sure if they may effect my issue…

my system is a one pipe STEAM system with 3 inch piping. they popped the new radiators with 2 inch and made them a 2 pipe system directly to the boiler.

the two new radiators get like warm, the entire system has continuous air no matter how many times i bleed it and currently out of 10 radiators only 2 are sufficiently heating evenly and running the house.

    Your comment about bleeding makes no sense. Steam systems have an air vent to automatically let the air out so the steam can come in. Steam systems do not ever get bled.

    Something isn't right here. If the new radiators are "two pipe system directly the boiler" how are they trapped? How are they vented?

    On the other hand, if it is possible to bleed something… this isn't steam.

    Maybe they hooked up supply and return to the same pipe no differential pressure

    i’m bleeding by shutting all the valves down and only opening one radiator at a time it pushes all the air out. I’ve had to do it in the past the air vents only do so much. And yes, there are air vents on every radiator and they are all new, i had no issues until new radiators installed and tome it seems it’s because they made them two pipe or because it’s only 2 inch. but no matter what I do there’s air pouring out at all of the radiators when i go around and do one by one. when you shut each down and go one by one normally all the air is finished by the time I get to the last radiator. He hooked up one supply line to the new radiators and one return line from new radiators from the new radiators. The new supply line is only 2 inches all the others around the house are 3 inches.

    ebbebratt, how could i check to see if that’s the case?

    the two new radiators are directly piped to the boiler and each have grapes. on of the traps they removed the guts because it was clogged and have no idea if they went back in

    This just isn't making any sense.

    If you are trying to bleed a steam system that's just not right. You don't bleed stream, and honestly if you are "bleeding" and "getting the air out" that also means that you have gotten so much water in there that it's going to take a LOT of work to get it even beginning to work properly.

    Please please we need at least the following pictures: boiler front and controls. General boiler with piping. One of the older radiators distant, one of it close enough to see the inlet valve clearly,, and one close enough to see what is being "bled". One of the new radiators distant, one of the inlet and valve, one of the outlet and trap, and one of whatever is venting the new radiator.

    I take it you Did Not get a qualified installer from this site? I added three new radiators to a single pipe steam residential system and told the installer what I wanted, who then threaded the black pipe sized to my specifications ( I consulted this site at the time years ago). I found radiators used in excellent shape

    I followed the same engineering ( or copied it) as the rest of the working radiators with no problems. I first started with someone who claimed to know steam, but didn't have a clue in the end and forced me to learn steam on my own. I ripped out the poor, non-working installation, and started all over again and never got a bill

    The right sizing of the pipes, proper pitch, good venting and skimming the boiler seemed to work in my case - you may want to buy some of Dan Holohans books available on Amazon to learn more

    All the best,
