A History Of Heating And Todays Methods
Central heating is very much thought of as a modern-day convenience. However it has been dated back to the ancient Greeks. A system of central heating provides heat to the interior of (or a portion of) a house or factory etc.
It is believed that in around 350 BC the homes of the wealthy and the Great Temples in the ancient times of Greece were heated by warm air that was circulated through flue systems in the floor. Today, because we have electricity to power blowers, forced-air systems warm billions of homes all around the world.
These forced air systems draw air into their pipes through to a furnace where the air is warmed and sent back into the room. There are different sizes of each model system so as to provide for every size room.
These systems are sometimes used with an AC (air conditioning) unit, air filter and a humidifier. The pipes themselves will normally be made from metal wrapped in insulating foam to keep in as much heat as possible.
Central heating and local heating differ because the heat is generated in one place, like a furnace room. The heat then begins circulating, usually either by steam thats being pushed through pipe work, by air that is being forced through piping or by water thats being forced through piping.
In parts of northern Europe, where the weather is quite cold anyway so they rarely need air-conditioning, central heating comes installed with most new homes.
Steam heating systems powered by gas, oil, or coal can are used in parts of the US, Europe and Russia, more so in bigger buildings. Systems of electrical heating are less commonly found and are only used in areas of cheap electricity.
