Residential HVAC systems have been around for quite some time, but that doesn’t there isn’t any room for improvement. Countless new upgrades and features have made these systems more efficient and useful than ever.
The discovery of fire and learning how to create and control it were two of the most important discoveries in human history. Fire not only enabled humans to cook their food, it also helped them to keep warm.
Those cave fires were an early step in the creation of home heating systems. The history of the home heating systems people use today is a long and interesting one.
Taking a Step Back in Time
It enabled humans to settle in colder climes. While humans have been heating their dwellings for thousands of years, the home heating systems in use today can be traced back about 150 years.
Archeological evidence shows humans used fire to warm their caves about 1.2 million years ago. Home heating systems have come a long way since then.
Ductwork, recessed wall heaters, tiny, mobile, heaters, heaters using electricity or natural gas, durable heaters made with advanced, lightweight metals, and heating elements made of ceramic materials, coils and tubes combined with electric blowers which channel the heat in any direction you want are available today.
The Ancient Romans
The ancient Romans are credited with creating the first sophisticated central heating system. Their system, called Hypocausts, is said to have channeled hot air created by a fire through pipes which ran under floors and behind walls. The ancient Koreans and Muslims were said to have had similar systems.
Prior to the 14th century, open hearths were used throughout the world to both cook food and warm homes. The invention of the chimney in the 14th century allowed the common man to better control the heat and smoke from their fires.
The 17th century saw the spread of wood and coal burning stoves to make fire to cook food and heat the home. In Russia in 1855 Franz San Galli created the first radiator.
It warmed homes by pushing hot liquids through metal pipes. Dave Lennox took it a step further by manufacturing and selling steel coal furnaces which used natural convection to spread the heat.
Albert Marsh’s Discovery
Albert Marsh’s discovery of the alloy Chromel improved home heating systems and led to the development of electrical heating elements. Alice Parker, an African American woman, invented the gas furnace in 1919.
Oil, gas, and electric furnaces keep hundreds of millions of people worldwide warm every day in their Glendale homes. Electric furnaces are popular because they cost less to purchase, install, and use. However, in the U.S. today natural gas furnaces are the most popular in Glendale homes.
