Help identifying my piping loop?...
So after all the wonderful recommendations here, I purchased "We got steam heat". Excellent and entertaining book!
I'm a bit confused on my setup however, and am curious about a few things.
I've enclosed two pictures, and commented on each.
1) There's a few obvious relief pipes, I dont understand.
2) I dont understand why my main goes out from east side of house, to the north of the house, no vents at all except at the radiators, then meets in the middle on the east side, same approx location as boiler, and returns, but also splits off to supply radiators on south side of house.
This return A, is the one on top that has the only main air vent.
Is it possible that steam goes out what I think is the Maine Return A, and they meet half way, and still condense back to the boiler. ie. is it possible steam is going up the one I labeled as main return B on the left?
Can condensate come back down the initial main and make it to the right on the header and down into the equalizer?
Does steam possibly go down the equalizer and across the close nipple then up the maine return B? I cant imagine this is possible, as everything below the fill line should be solid water, correct?
3) Would it be wise to add in a nipple/shutoff where I noted "Skimming Tap goes Here"?
4) Since it looks like I have an electric cutoff probe, is there anything in my setup that I should be leeching off a pint or so every now and then, or is this pretty much a closed system.
A few things I'm planning on doing.
1) Insulating all mains.
2) Putting an air vent almost in the middle of the east end where it branches off to second part of house.
3) Adding Skim valve.
4) Cleaning Low water probe (Exactly how do I do this?).
5) Adding a water meter at auto fill.
I have someone coming for the first cleaning in two years, so I want to be prepared for them, and have them install the vent and skim valve. And be prepared.
Since I have a Pressuretrol installed, there's no harm in a electronic thermostat, correct?
Thanks in advance all! Hopefully knuckleheads didn't install this. 8)
