An electric furnace is a heater that functions using electricity as its main power source to generate heat and push the air through the central heating system. There are a number of companies that make these electric furnaces. Some of these companies are Carrier, Trane and Coleman. Electric furnaces are used in homes, apartments, mobile homes, and offices. These furnaces are commonly mounted in the cellar, cabinet, utility room, or loft. They can be installed with your ductwork on hand to allow heat to circulate from the electric furnace.
In terms of costs, electric furnaces are cheaper than other heating alternatives. They do not need extra fuel pipes and expensive tanks for fuel storage. They do not have need of any exhaust. There is a major savings in material costs and installation time. Electric furnaces have movable parts, which makes the operation affordable and maintenance easy. They have a small central heating unit with a blower fan and can be modified to add on heat pump systems or central air conditioning units.
Using an electric furnace has some advantages. An electric furnace can be controlled to allow uniformity of temperature. Since it uses electricity and not oil or gas, it is considered clean. It is considered safe because it has an automatic breaker that protects it from overloading. Operating it is easy and it operates quietly. With an electric furnace you don't have to use a pilot light or combustible fuels, since it does not have a flame that can put your house in danger.
The operation of the electric furnace is simple. Electric furnaces use a fan to force air across a resistor. The resistor is a wire coil, which creates heat through electricity. The heated air is then distributed through ducts to give warmth to your home or place of business. The furnace works depending on the thermostat, which is a simple element that serves as a thermometer. When the temperature of the house drops below the set temperature on the thermostat, the thermostat alerts the electric furnace, which is usually situated in the basement of a building, of the drop in temperature.
The most important component of the electric furnace is the heating coil, which turns very hot when electric current is passed through it. The heated air around the coil is then regularly blown into the house through a blower. The pressure that is exerted by the blower on the heated air warms the air further. The cold air that was in the house replaces the hot air in the electric furnace. This cold air is in turn heated by the heating coil of the furnace and is blown back into the house. Some furnaces also take in fresh air from the atmosphere outside. The thermostat shuts off the electric furnace automatically when the air reaches a particular temperature.
The use of electric furnaces is now being accepted and has heightened the effort in energy savings and prevention of global warming. It is affordable, easily maintained, clean and efficient.
