This is how homes are heated in Korea. It's called "Ondol" heating. The early systems used cylindrical pieces of charcoal as fuel, and exhaust gases were pumped through the pipes. Very Bad! The next generation of Ondol still used charcoal, but this heated hot water and it flowed through the pipes. Better! The last time I was there, I had an apartment with Ondol heating, but the water was heated with an oil furnace. Even better!
It's a nice system if you're walking around with bare feet or in your socks. Just make sure that you know where the hot spots are...
