So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

A History Of Heating And Todays Methods

By Mary Barbara Dickins

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 forced-air systems are sometimes used together with a humidifier, an air filter and/or an air-conditioning unit. The piping in the system will usually be metal wrapped in an insulating foam of some kind to keep maximum heat in.

Local heating differs from central heating as the heat is generated in one place, e.g. a furnace room. The heat then begins circulating, usually either by water thats being forced through piping, steam thats being pushed through pipe work or by air that is 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.

Systems of steam heating, by oil, coal or gas can be found in North America, Russia and some parts of Europe, usually in larger buildings. Electrical heating systems are less common and are only really used along with cheap electricity.
