Cast Iron Radiator?

[pine3874]

I believe this is cast iron. It has been there so long that the tree grew around it. Any ideas as to what it could be? Thanks for looking.

Interesting find… I have never seen a radiator designed like that.
It does someway resemble one though.

I think it may be part of a boiler for a steam engine or steam heating.

That is a section of a steam or hot water boiler.
