Both types of dryers function similarly -- air is drawn into the dryer, passes through a heating coil, warms the clothes inside, collects moisture, and is vented out. Gas dryers use gas to create the heat, and electric dryers use electricity. Both types use an electric fan to distribute the heat. Even though both types require a steady stream of electricity, gas models are slightly more efficient.
Gas dryers use electricity to run the motor but gas to dry the clothes. Since gas dryers are rated in British Thermal Units, you need to convert the BTUs to therms, which is how the utility company charges for gas. A typical dryer uses between approximately 11,000 BTUs per hour because the gas cycles on and off during the drying time. One therm equals 100,000 BTUs, which means a dryer uses .11 therm per hour. The gas costs roughly $.11 for an hour. Electricity to power the drum uses .15 per ...
