Home heating; the absence of cold.
Home heating has many sources of cold air removal. Let’s take fire places for example; fireplaces have been a heating source ever since fire was created, however fireplaces were first used during the Roman era. Not every Roman had a fireplace, mostly the elite Romans were privileged.
Home heating has evolved to include every home and business that uses a source of heating. This includes central heating systems, furnaces, boilers, heat pumps, geo-thermal, solar heating and fireplaces. Heat moves to the cold, so heating the interior of a structure consumes cold air.
With furnaces though, as a home heating source, the cold air is sucked back to the furnace through the return and reconditioned through the heat exchanger. This makes the cold air warm air again and again, thus warm air furnaces. With boilers as a home heating source, the radiation of heat blankets the exterior walls keeping the home conditioned with heat, thus radiators.
Geo thermal systems use the depths of the earth to create heat or cool depending on the season of course. Heat pumps utilize refrigerant and coils to provide home heating or cooling. In recent years heat pumps have gained popularity and surpassed the boundaries of the warmer climate states and have moved north as a source of heating. However in colder climate regions, a secondary heat source like electric elements or a furnace has to be used to make up the short comings of heat pumps.
Solar heating will become a major source of home heating in the near future when it becomes more affordable for the common folk. However, if you are building your own home, solar for heating could be rolled into your mortgage. This will make your home heating less of a out of pocket expense.
