ive worked on one of those in my life when i first started about 10 years ago. it was in a basement with a bunch of round lines coming from it. looked like a octopus
 
At least yours was converted to gas. This one is still guzzling oil like it's going out of style:

Although mine did have the blower 'upgrade'. :D

Mom lived in a house with her Mom & Great Uncle Fred. They had one of them, still burned coal in the 50s. Uncle Fred would return from downtown at night after hitting the bars. He'd head down to throw come more coal on. Mom would have to follow him down and keep an eye on him. He tended to get carried away and roast the house. Not like having a T87 on the wall!
 
Most of those, at least up here, date from the 1920's and 1930's. They were originally coal fired and most were later converted to oil. Gravity is correct. They were a gravity hot air system. No blower, no moving parts in the original. A single return, strategically located and an octopus style supply pattern.

We have slowly removed them over the years up here. To the detriment of comfort in many cases. They weren't overly efficient but were extremely comfortable. The house seemed to fill up with warm air.

That one is in much better shape than most that I run into. Not a "Wall of Shame" in my book.

That's how we refer to them as, an "octopus" just figured the was the correct term lol, never worked on any but seen one.

Last year I worked in this super old oil to gas conversion boiler, it was really weird, I had 3 people staring at me while I tried to figure out how to lite the thermocouple, I had to pull the burner out and lite it then put it back together. Im sure it wasnt the right way but the customer was less than helpful so I improvised. Sorry for the hijack.
 
Saw a few of those denver co, gravity systems, recommended replacement but the people seemed to like them a lot. I agree that this one is a wall of pride pic except for efficiency.
 
That is the cleanest one I have ever seen! Think about it, this thing has been running for close to 100 years! I think it belongs on the ***. Kind of sad to see them go.... I'm bidding to tear out another gravity boiler right now, but it doesn't look like that.

Believe it or not there's anouther in same room that looks just as clean ingot a pic of it if you guys want to see it... only reason its in shame section is the age and needs replaced

The Octopus

My Grandmother had one of these. It was coal that was converted to oil also. Works well, but very inefficient. I have replaced a couple of them in my days. If you do replace one, remember the top portion where the "tentacles" of the "octopus" are connected contains asbestos
