Central Heating Advances – From Rome to the 21st Century

The ancient Romans figured out how to keep their homes toasty warm long before Benjamin Franklin flew his kite and we got busy inventing ways to harness electricity for our comfort.

Roman architects designed a central heating system called a hypocaust. The word, hypocaustum means “heat from below.” The raised floors were held up by short pillars and spaces beneath them and inside the walls were heated with the hot smoke and air from the fire chamber. Walls were fitted with ceramic box-shaped tiles that served as flues to channel the burned air and smoke to the outside, as well as to warm them. The more warmth needed, the closer to the hypocausts they were located.

It was a pretty expensive and labor-intensive method, so hypocausts were reserved for public baths and upper class villas. In about 25 B.C. Sergius Orata figured out how to cut down on the overhead by putting the male and female bathing rooms close to the hypocausts and right next door to each other.

Korean traditional architecture uses an Ondol. This underfloor heating method depends on direct heat transfer from a wood fire maintained underneath a thick floor made of masonry. From the central firebox or stove area, usually accessible from the kitchen or master bedroom, a system of horizontal channels spider out underneath the structure. A chimney on the opposite side of the building from the firebox ensures a decent draft system.

Great Fountains of Rome

If you visit the Piazza del Campidoglio in Rome you will find three fountains of interest. In this imposing square, these fountains each have a particularly interesting history. They haven’t actually been in place in their current setting for that long, but each fountain has had a rich and varied background. In fact, the sculptures you’ll see on these three fountains can be traced back to the early days of Christian Rome.

The first of the three fountains that you’ll probably notice in the piazza is the central large fountain that leads up to the magnificent Palace of the Senators. Although originally planned by Michelangelo when he laid out designs for the piazza, the fountain was only constructed in the reign of Sixtus V who diverted a water supply from the Acqua Felice that could then supply a fountain. Original plans had decreed that this fountain would contain the figure of Jove as its centerpiece; instead it was built around the figure of Minerva who stands as the figurehead of Rome. Minerva’s statue has partly been restored in modern times but the torso was brought to Rome from Cori so it is of great historical significance.

In front of the Minerva fountain you’ll find the second fountain-decorated with the sculptures of two river gods. These statues are of great historical interest; unlike many lost treasures they have survived without burial in all of the turbulent times since Rome’s downfall. Initially they were located in front of Aurelian’s Temple of the Sun but they have since been moved around various settings in Rome before settling in their current location. Like the Palace of the Senators before which they stand, much of this fountain is constructed of travertine. This fountain seamlessly melds into the palace, as if it had been placed there at the dawn of time.
