Central Heating

In winter there is nothing better than getting back from frozen outdoors to the warm and cosy
interior of your house. The reason why we are not freezing to death in our houses during the winter is the central heating
system installed almost in every building in Europe.

This seemingly simple invetion is really one of
the most important wonders of the human technology, which dramtically changed the way we lived
forever. The system provides the heat to every room of no matter how big building through the
complex installations of pipes and makes our households, offices, schools warm enough to survive
inside even in the coldest parts of earth.
Althrough the prototype of the system that we use today was developed in the late 18th century, the
first references about it are dated thousands years back into the past.
Sooo, now; what do you think? Is it possible that the ancient Greeks, more than 2 thousand years
ago, had enough knowledge to came up with so complex thing as a central heating system?
Just speak if it's Greek.
