My heat pump dryer takes a long time to dry clothing.

Your heat pump tumble dryer uses hot air to absorb moisture from your clothes to get them dry after a wash. After this air passes through the drum, it goes through the evaporator which removes the moisture. This is collected as condensation and stored in a tank. The remaining air is re-heated and sent back to the drum to start the cycle again and continue drying your clothes. While conventional tumble dryers release hot air used to dry clothes, heat pump technology conserves and reuses it. It will take longer to dry clothing as the maximum temperature reached is 50°C. In comparison, the maximum temperature reached in a condenser dryer is 70-75 °C.
