Ok here is my problem. In my appartment building I have a steam boiling system. It's a Weil- McLain LGB-21-5 It's
big and old,
The unit runs well at 3kps. The building has 68 units and 2 to 4 rads per place.
But when the boiler runs the left side of the building has no problems.
The rads get so hot people have to open the windows. The right ride is ok until you get to the front of
the building . Unit
12-13
112-113
212-213
312-313
412-413
all have no heat all all going to the kitchen/living room. BUT are hot in the bedroom and bath.
BUT
If were to leave the boiler running full tilt it gets warm/hot after a day or so but dosent last unless
the boiler runs FULL OUT. I can not afford to pay 8000 a month in heating bills like last year so it's
time to fix this problem. I had a tennant in 412 that tried to disconnect the rad in the living room this past
summer to sand blast it without my permission. She just moved out. So this year when i turned the boiler
on and walked through the building i heard cold air hissing from the rad so in order to fix it I took it off on one end and
cleaned the thread, while it was dissconnected I heard hissing air I dont know if it was pulling air in or pushing out
but I tightened the pipe. I dont know
exactly how to bleed the system of air. Or if you even have to with a 2 pipe steam system.
I called in a company to
take a look they told me if I were to try and clean out the pipes with solution it might clog somewhere else.
Is this true? Also if someone can recomend a cleaner for these pipes. that guy who came last time charged me 100
to tell me nothing.
I also seen a trap like thing in the basement in appt 13 under the kitchen but I had no luck removing the cap. I might
want to check with someone before I do anyway.
So any advice would be GREAT. Thank-you
