Re: Heat never reached my son's room very well...
The vent on that radiator looks like a Dole #1933, which is a very slow vent- for perspective, slower than the Hoffman #40. Assuming the main vents are OK, try changing the Dole to a Vent-Rite #1 which is adjustable. This will let you fine-tune that radiator.
Re: Heat never reached my son's room very well...
As @ScottSecor said it could be the heat anticipator or cph setting in the stat not allowing the boiler to fire long enough. May need to increase that setting and fool with the vents. The main venting inthe basement is crucial.
Re: Heat never reached my son's room very well...
Start with putting in a larger air vent . a maid of mist or Gordon c . I like the maid of mist because I can change the orifice to help balance the system. also Are the Basement pipes insulated, if not insulate them . I prefer 1 inch thick fiberglass insulation, especially in the furnace room. it can be trimmed out to go over fittings and holds the heat in the pipes better than 1/2 inch thick. if the basement is laundry and storage cover all the steam pipes . in will not only get the steam further into the house but will save you a lot on your heating bill. steam pipes where meant to be insulated. asbestos litigation. has caused a lot of insulation to be removed, but those selling often don't put anything back.
Re: Heat never reached my son's room very well...
That's a steam radiator, not a hot water radiator.
OK. If a steam radiator doesn't heat, it means that the steam isn't getting in or getting to it. Is this the last radiator on a steam main? Is there a main vent on that main? If not the steam just can't get to the radiator... On the other hand, if the vent (the silver thing) is too small, then the air can't get out of the radiator fast enough -- and the steam, correspondingly, can't get in.
Of course, one might add that the pipes leading to the radiator have to be pitched enough for the condensate to get out of them...
Many possibilities here.

Re: Heat never reached my son's room very well...
Is the thermostat anticipator set up for steam, most thermostats come set up for warm air?
Are the main vents in good working order and properly sized?
Has the boiler been properly serviced and is the water level steady in the gauge glass?
Are the vents too large in the other rooms, especially the room with the thermostat? If this is the case, the thermostat may be satisfied before the steam reaches your son's room.
Steam systems sometimes require some balancing.
Are the steam mains insulated and pitched away from the boiler (assuming they are typical parallel low and not counter-flow.)

Re: Heat never reached my son's room very well...
Is that on a first floor and is the ceiling open so you can see the piping to that radiator or is it in a hard ceiling or on a second floor? Can you see where the runnount for that radiator connects to the main?

Re: Troubleshooting HW baseboard
A couple options:
Close the ball valve above the boiler on the supply, put fill valve in fast fill mode, flip the lever.
Flow goes around the system and you could purge some from the boiler drain, not ideal but workable with fast flow.
Easily add a valve between the two ball valves on the return. Press tee in there with a full port ball valve with hose connection.

Re: Replacing an old condominium thermostat
I'm not 100% convinced that's a Normally Open zone valve, but if it opens when then wires are disconnected and not touching at the thermostat, then... ISU is Installer Setup. You need to access it and go through the prompt so the thermostat knows what to do. Wire R+Y and do Step 5 and see what happens.bokerman said:@HVACNUT many thanks for the comment. I don't really understand the note 5, what is ISU? I see three modes on the thermostat menu, Heat, Cool and OFF. There is nothing more in the Menu except from clock setting and similar. Again, thanks a lot for the help!! Here is how it looks right now, it is basically acting inverted (turns on when it should turn off):

Tutoring help for NYS & NYC Master Plumber Exams and All Plumbing Civil Service titles
I've been helping guys and a few gals study and pass their exams as needed for as long as I've been taking Plumbing & Steamfitter, Boiler Inspector exams (38 years).
Math never came natural to me, but I've developed tools 🔧 and study habits that win! I've easily taken over 30 exams over the years and always scored very high...through hard-core study habits & determination 💪
There's been a slew of young men reaching out and I'm tutoring & guiding them as they need it. A few hours here and there to get focused in. A Tune up scrimmage before the Big Day.
I've been in their position, just scraping by and I'm not looking to buy a new boat here! My old, 12 foot rowboat 🚣♂️ on the Reservoir is good enough for me. Here to help you pass. Mad Dog 🐕
