Reply to comment by Full-Mulberry5018 in TIL that Koreans have had heated floor technology since at least 1,000 B.C.E. by Nice-Violinist-6395
Actually, while this is true, the title of this post is just wrong.
The earliest example of under floor heating is actually from 5000BC and was found in modern day... North Korea.
So, Korea is still technically the first, before Rome. It's just the date is wrong in the title... Thanks a bunch for the really, really unhelpful TIL OP.
