Long time lurker, first time poster. We recently bought a really old colonial in Montclair, NJ. The steam heating was in a complete disarray (no maintenance in likely 6-10 years by previous owners). Seized/solidified pigtail, glitchy low water sensors, a mess of wires to the thermostat, leaking valves everywhere, etc.. All of you plus "Art of Steam" ( thank you Dan!) helped me enormously, so thank you!
I just about got it all tuned in and running fairly smoothly. No banging anywhere, near silent heating of radiators, every radiator heating at the same time (a minute roughly from system kicking in), 0.5 cut in 1.5 PSI cut out on the Pressuretrol. However, I was in the basement doing some work today and observed my boiler heating cycle when thermostat activates it and I wonder if what I have is considered short cycling. Going from cold - thermostat activated the boiler, it ran for about 2.5 - 3 minutes, then pressuretrol cut it out. It sat for about 40 seconds then activated again and ran for 1 minutes then cut it out. It then cut in again and ran for about 2 minutes and then cut out and at this point Thermostat was satisfied. In other words:
- 3 minutes
- 40 sec pause
- 1 minute
- 40 sec pause
- 2 minutes
- Done, rooms heated
Does this look like a short cycling system? If yes, does that mean I have an issue with air being trapped somewhere?
