Re: Can someone explain this hydronic loop heating.
It looks like the air eliminator was eliminated.

Re: Gas shut off valve
Use caution if the valve hasn't been used in a while. You may want to loosen the nut on the other end to get it to move easier. This may cause a slight leak but will stop when you retighten the nut
Re: Gas shut off valve
That is the type of quarter-turn valve used to turn off gas. You will need a wrench to operate it.
As to whether it is the main or not, we cannot tell from the photo. Trace it back toward the meter; if there are no other branches that is the main shutoff.

Re: Trying to sell my steam radiators... Any tips?
Can you share any pictures? I would recommend listing them at a a very reasonable price but a price higher than the scrap value. This will optimize your chances of them going to good use.

option 3: run a new line along another route. What’s the frost line (depth) for your area.

Re: Can someone explain this hydronic loop heating.
I would say it was someone’s useless attempt to get more heat out of that unit.
Re: Can someone explain this hydronic loop heating.
I can see no purpose to that extension from the location where there should be a vent of some kind of vent to expel air from the convector. You may find it in a circa 1950s popular mechanics magazine, when there were many innovative ideas. But I can see no benefit.
Re: 1933 Burnham Boiler - Questions and Potential Replacement
That Burnham 2708 is rated 1550 square feet. Double-check your radiation- also see if any rads have been removed over the years.
Re: Replacing cast iron radiator with smaller one
If so, that's probably also true for the rest of the house. A heat-loss calculation would determine that. What that means is the system would run at lower temps, so the rad size should not be changed.
