3,300,000 BTU Steam Boiler
New poster and this seems to be the authority for steam boilers...
I'm starting renovations on a, new to me, 8-story building. Total square footage is around 80K. The steam boiler was installed in 1994. The caretaker of the property was there when it was installed and knows how to run it. it hasn't been run at all since 2005. There were no steps done at all to winterize the boiler except draining it down.
Full disclosure; I have no experience with steam boilers, but have above average HVAC experience. I'm comfortable working on and repairing a traditional water boiler.
I'm trying to figure out:
1) What are the odds that this runs?
2) If it does, what are the things that I should be considering first or looking out for? As an example; I've noticed that some of the radiators in the building are missing the steam air valves (presuming they were scrapped or otherwise stolen). Are steam radiators prone to cracking when frozen like a traditional radiator or am I more likely to get lucky because they don't hold water?
3) Long term; should I look to replace this system? The building is 100+ years old. The radiators and piping all appear original save for a few repairs that are visible along the way. Apparently tenants had previously complained about uneven heat and it being too warm in the summer (obviously a separate issue that needs addressed).
Quick background. System is natural gas and the brand is a "Peerless Cast Iron" boiler.
I appreciate your feedback.
