Yes, using a dryer with no heat will make the drying time longer compared to using it with heat. When you run the dryer without heat, it will only blow cool or room-temperature air into the drum, which is not effective in removing moisture from the clothes.
The purpose of using heat in a dryer is to increase the temperature inside the drum, which helps to evaporate the water from the wet clothes. Warm air absorbs moisture more efficiently, which leads to faster drying times. Without heat, the drying process relies solely on the movement of air and the natural evaporation of water, which is much slower.
Using a dryer without heat might be suitable for certain delicate fabrics or items that you don't want to expose to high temperatures. However, keep in mind that this method will significantly extend the drying time, potentially taking several hours or even longer to dry your clothes thoroughly.
If you want to reduce energy consumption and drying time, consider the following alternatives:
Air drying: Hang your clothes on a clothesline or drying rack to air dry. This method consumes no electricity and is the most energy-efficient way to dry clothes.
Spin cycle: If your washing machine has a high-speed spin cycle, use it to remove more moisture from the clothes before transferring them to the dryer. This can significantly reduce drying time and energy consumption.
Use the dryer efficiently: When using the dryer, make sure to clean the lint filter before each load and dry full loads to maximize efficiency. If your dryer has a moisture sensor, use it to avoid over-drying.
By using these energy-saving practices, you can decrease the time and energy required to dry your clothes while still achieving effective results.
