The ancient Romans are credited with developing the first central heating system known as a hypocaust, which circulated hot air under the floors and through pipes in the walls of buildings. The modern forced-air heating system was invented by American engineer Alice Parker in 1919, allowing for more efficient and effective heating in homes and buildings.
