In the colder parts of Spain, some villages still have houses with an ancient underfloor heating system known as a 'gloria'.  The fire would be lit once a day and when it was burning well the firebox would be covered to slow the burning rate and keep the heat inside.

"The warm exhaust gases from the combustion heat are led through one or more ducts  that run under the floor of the heated room(s), and then rise through the chimney. The floor and the walls slowly radiate this heat into the room. In summer, a natural air current in the gloria cools the room(s)."

That is so Cool!  I have been thinking of doing something like that in my husbands office, though with a RMH inside and the pipes running through the floor, since he doesn't have room for a big bench.
 
Let me tell you a story about a man named Jed. He made this tiny ad:
Switching from electric heat to a rocket mass heater reduces your carbon footprint as much as parking 7 cars
