Default Gravity Furnace (aka) Sea Creature

Had my first MONSTER a few weeks back and thought I would share.

Very nice. Something like a 40% effiency rating if I'm not mistaken. I grew up with one of those.

I have always wonder why they are called gravity furnaces when they flow upwards?

What goes up,must come down.

Notice how it dwarfs the Water Heater.

Funny, but for some reason thought it would not heat the second floor of this row house.(I was wrong)

Wonder no more.

Having no blower, they rely on the fact that the cooler air is heavier and sinks do the force of gravity only to be reheated and rise. That is why the pipes are so large.

Possible asbestos tape, and most likely the mud around the door.
