Induction Heating Uses Frequency To Provide WarmthWith induction heating, electricity is passed through a wire coil through which a work piece is passed. The coil produces radio frequencies that heat the work piece. In a home heating unit, air can be forced passed this heated metal and then pushed into the home to provide warm air. In most cases, an induction heating unit is more efficient that those using other fossil fuels and offer less danger than using potentially explosive fuels with a fire source. Most buildings are equipped with a central heating, ventilation and air conditioning systems with one main unit centrally located in the structure. Many larger buildings use induction heating units as part of their central HVAC units and today, some homes are using the induction method to provide heat for their homes, replacing their centrally located gas or oil-fired furnace. Consider All The Uses Of Heating Coils A good example of induction heating could be the stove top, which when turned on heats a metal coil. Not many modern stoves however use true induction heating as many pots and pans used in homes are made of copper or aluminum and the non-ferrous metals do not react with the same result as ferrous metals. Essentially, for a metal to be heated through induction, it needs to be magnetic. It is the magnetism created by the radio frequency going through the coil that produces the heat with induction heating. Some modern stoves do utilize induction, requiring the use of specific metals in the cookware, but traditional stoves use conduction to heat the cookware for cooking. A simpler look at induction heating is that with gas or oil furnaces, the fire heats the air in an exchanger which is then forced by a fan through the rest of the house. Cold air is dispersed from the rooms, back into the furnace through the duct work. With induction heating, a metal conductor is heated by radio frequency, heating the air as it passes by the heated metal. It can then be pushed by a fan throughout the rest of the home. |
