Heat pump tumble dryer.
5/5
Didn't even know that there were different types of dryer. This is a heat pump dryer. It recirculates the hot air. That's how it is able to reduce the cost of the drying.
It's quieter, doesn't push hot damp air into the atmosphere and never causes the condenser to drip water onto the floor.
Drying cycles are initially a little longer, but the dryer sensors ensure, where possible, a quicker cycle is employed.
