Condenser dryers are, next to heat pump dryers, the most sold type of dryer in the Netherlands. Because they do not work with a heat pump but with an electric heating element, the average drying program of a condensing dryer is shorter than that of a heat pump dryer. The condenser dryer dries with a relatively high drying temperature. In purchase, the condenser dryer is usually cheaper, but because of the use of the heating element, they do not dry energy efficiently. Most condenser dryers have energy class B, which makes them more expensive to use than heat pump dryers. With a condenser dryer, water can usually be drained in two ways; with a drain hose to the water outlet, or it is collected in a built-in reservoir. If you use the reservoir, you will need to empty it after each drying cycle.
