Generated explanation

The illustration compares cutaway views of an electric forced-air furnace and a gas forced-air furnace, joined by an equals sign. The electric furnace contains resistance heating elements labeled as typically 5 kw each, with an electrical supply entering the cabinet. The gas furnace shows a burner assembly, heat exchanger, and vent connector. Both furnaces have a blower in the lower compartment and a cold air return. The diagram presents a 25 kw electric furnace as equivalent to a 100,000 BTU input gas furnace; no defects are depicted.
