One fun thing we like to post here on occasion is how the science of heating and air conditioning came about in the aeons before we reached the technology we have now.

DID YOU KNOW?
In ancient Greece, they primarily used two methods of early central heating to keep their homes, temples and other buildings warm – the “hypocaust system” and the “sun heating system”. A hypocaust system used a furnace that was placed under the floor of the basement. The heat is then distributed throughout the floor using flues connected to the other rooms of the building. The sun heating method required a house to be designed so that sunlight would come in during the peak hours of the day, get processed through a certain type of window, and create heat that would then reach and conduct certain heating objects and radiate warmth from there.

The first known use of central heating in Ancient Greece was the Temple of Artemis in Ephesus – one of the 7 wonders of the world. The first known instance of heated bath water was a bath house in Olympia and it used a furnace placed under a water tank that then was dispensed into the pools.
