6. Central Heating (Hypocaust System)

The Roman hypocaust system was a groundbreaking method for heating villas and public baths. Hot air circulated beneath raised floors and through wall flues, providing warmth throughout entire buildings. This ingenious approach is the ancestor of today’s central heating systems, demonstrating the Romans’ commitment to comfort and innovation. Modern underfloor heating and HVAC systems reflect these ancient principles. Reference for more about the hypocaust.
