Picasso's French wood burner

I came across this monster which shows Picasso in his French studio.
I'm guessing all of those pot like structures are heat exchangers grabbing heat from the chimney exhaust.

Is this a common French design?

That looks like it actually is some sort of clay pot radiator contraption to throw out some extra heat. I don't know anything about French stoves but it wouldn't be surprising if this is a one of a kind piece of his work. Nothing common about him. Saw some of his work in a gallery exhibition several years ago. Wow, just wow.

Terracotta pots ares still in use for trapping heat!  This is how the "kandle heeter" works.

I love the heat exchanger! It's pretty too. Just added that idea to my notes.
Now my head is thinking about weird heat exchangers...
Cool, thank you for the post!

That stove is very cool. Had to look it up quick, most of the results reference Picasso and that photo. I saw a few places selling them (I think, they weren't in English, and I don't speak anything else). Some photos of ones with a shorter "stack" of radiators. I found this similar design at this site, they are also discussing the photo with Picasso. I couldn't get a direct link to post the image of the other stove here, sorry. My browser kept on downloading a text file when I tried to get the link. Looks like it's also French, and also heating a big room, a church. Couldn't really dig up more, but now I want one.

There's that picture. Messy link, but it posted.  
COOL...

Nice find.  So, the stoves were made in Alsace, and it looks like all the mass and heat exchange units were made from steel.
