Dryers remove residual moisture from clothes and fabrics, usually after washing. The clothes are placed in a rotating drum called a tumbler, where heat is circulated to remove the water. The tumbler rotates slowly to leave enough space between the fabrics for the heat to pass through. They produce heat using heating coils or by heating outside air and drawing it into the drum. Dryers are available as standalone units or integrated with washing machines.
Electric dryers plug into standard AC sockets and use electricity to generate heat. They are the cheapest type of dryer, but are usually expensive to operate and maintain. They have poor efficiency and use up more power than other types.
Gas dryers
Gas dryers are powered by natural gas obtained from the mains supply. They have lower operating costs and require less maintenance than electric dryers. They are highly power-efficient because most of the heat is used for drying rather than powering the machine. Heat pump dryers
Heat pumps are electric dryers that remove moisture from the hot air and pump it back into the tumbler. This reduces the need for constant reheating, making them cheaper to operate. They are relatively expensive, but they are much more efficient than both electric and gas models.
Filters. Choose a dryer with filters on the walls to trap dust, lint, and other particles from the fabric. This will keep them from clogging the vents and help maintain efficiency. Look for one with removable filters for easier cleaning.
Drying time. Choose a dryer that can dry a small load (about three to five pounds) in ten minutes or less. Note that overloading can slow down the drying process, so keep within the dryer’s ideal capacity to minimize drying time.
