There are several types of dryers commonly used, and the main ones are:

Condenser dryers: These dryers extract moisture from the hot air and condense it into water, which is collected in an internal tank or directed to a drain. They are ideal for those who do not have an external air outlet, as they do not require ventilation.

Vented dryers: This type of dryer expels the hot and humid air outside through a tube. They are less expensive than condenser dryers, but require an external air outlet.

Heat pump dryers: This type of dryer uses a heat pump to heat the air, which reduces energy consumption compared to condenser and vented dryers. They are ideal for those who want to save energy and reduce their electricity bills.

Solar dryers: This type of dryer uses solar energy to dry clothes. They are an eco-friendly and affordable option, but depend on the climate and the amount of available sun.

Gas dryers: These dryers use natural gas or propane to heat the air, making them more economical than electric dryers. They are a good option for those who have access to natural gas or propane and want to save money in the long term.
