More info: Technically, how hot a clothes dryer gets depends on which part of the unit you are considering. The hottest area of the clothes dryer occurs in the heating element. Air is drawn into the heater duct and heated to temperatures ranging from 200°F-300°F. Once the air reaches the inside of the drum, evaporating water cools the air to 90°F-170°F.
Factors Influencing Clothes Dryer Temperature.
Several factors influence the internal operating temperature of a dryer including cycle setting, load size, dampness, room temperature, and airflow. The make and the model of the clothes dryer, as well as its age will also influence operating temperature.
Different Dryers Use Same Energy
Unlike many other appliances, the amount of energy used by a clothes dryer tends to vary very little when one model is compared to another. Because of this, dryers are currently not registered in the U.S. government database of ENERGY STAR machines and are not required to display a related certification sticker. On average, the clothes dryer is the second most expensive appliance in a household from an energy consumption point of view, requiring an annual supply of electricity or gas worth $85.
Gas vs. Electric
Electric dryers use coils to create the heat, while gas dryers rely on a burner. Although gas dryers cost on average $50 more than their electric counterparts, they pay dividends at the energy consumption end. A typical load of laundry requires 30 to 40 cents of electricity, but only 15 to 20 cents of gas energy cost. A savings of 50%.
