History

• Romans created under floor heating systems called
  "hypocausts".
• Under the floor would be an empty space with
  brick or stone pillars at regular intervals to
  support the floor.
• A furnace lit at one end of the room and the heat
  from the fire would circulate freely within the
  under floor space, heating the floor above.
• Flues or channels within the walls would carry
  the hot air upwards warming the tiles or bricks
  not only in the floors but the walls as well.

History

• Under floor heating died out after the Romans
  left
• Britain drifted towards the Dark Ages.
• Central heating was not revived again until the
  start of the industrial revolution in the 19th
  Century.
• Rich merchants and landowners could afford to fit
  water filled pipes and cast iron radiators in
  their grand mansions.
• If the Victorians had developed under floor
  heating instead of radiators, then all houses
  today would have under floor heating by default.
• The modern system of radiators did not enter the
  mass housing market until after the second world
  war.
