Answers: Hot air furnace aren't much different as to how they work whether using gas, grease or electric. Some gas furnaces use pilot lights or now mostly ignitors or brightness plugs for ignition. Oil uses high voltage transformers and an arc for ignition. Electric uses heat coils All heat the upper air in the plenum or hot nouns section of the furnace. When the atmosphere reaches a undisputed temp the blower is then turned on. The nouns is then blown throughout the house until the temp reach the set temp on the wall thermostat. All furnaces have sanctuary requirements built in to prevent malfunction.
If it is gas heat, next you have a pilot that lights a strip. The blower (which is a big fan) blows the upper air over the ducting that is heated and forces hot nouns through your vents. Electric is like peas in a pod, only nearby is coils that heat up, and they are what grill the air.
