Boiler control settings

Niss3zx Member Posts: 10
I am a do it yourselfer. I own a 4 family home in Queens NY.  2 story building with 2 apartments on each floor. Thermostat located on 1st floor. Setting is between 73/74.  Installed all new Maid o Mist adjustable air vents in all radiators. Gorton # 2 in main long run and Gorton #1 on short run.  Question # 1 . Based on the pics provided would you say my settings are ok? I've made adjustments. Question # 2. I have only one tenats that complains she is cold. Her apt contains 3 radiators.  2 radiators are with "D" and 1 with "C". I recently changed it to that. Orginally i had  2 "6" and 1 "C". I followed Gortons website in regards to number placement. Please be advised her side of the apt located on 2nd floor  has a shaftway with a window. Unlike the opposite side where the next building touches.  Is it possible I am losing heat or my settings are not correct or maybe she is just crazy??.Any help will be greatly appriciated. Thank you.

    You Pressuretrol settings are reasonable.

    The first question I would ask, then, if do you have any way to determine -- yourself -- whether your tenant's radiators all heat up reasonably quickly, along with the others? If they are slow to heat, you may be able to adjust the venting elsewhere to bring it more in line with the tenant's apartment. Otherwise, you are getting all the heat you can out of those radiators.

    In which case, you really can improve the situation only by reducing heat loss from that apartment. Storm windows? Exterior (or roof) insulation? Check for draughts?

    Jamie thank you for the quick respose. No determination if they all heat up ar the same time. No complaints from others. Again her apt has the max allowed vents  for her radiators. Thermal infrared imagine gun does shows radiators are putting out. Again old 1930s building that is frame. Main control was orginally set to 10 psi. I turned it down to 5psi.  Will this cause any concern or any benifit. Thank u again

    That main is your manual reset backup -- 5 psi is fine.

    Put a wifi thermometer in her living space and you'll see if she's really cold or not. Of course cold to her might be hot to you.

    but that's the first thing I would do before messing around with the venting etc. You have to know the truth of the matter first.

    Right. Some people are “cold” at 75° F.

    Difficult to impossible to keep everyone happy. I agree with the above posts put a recording stat in the problem apartment. You may find that the "problem" does not exist.

    You could put a piece of electric baseboard in there to boost the heat. When she finsd out she is paying the electric to run that she will shut it off and decide everything is ok
