Bin with the device very satisfied (in use for a month). The only disadvantage compared to a dryer without heat pump is significantly längerere drying time. (About 2 hours 15 minutes). This is the "price" for the low power consumption and system-related, as the heat pump extracts the heat energy from the ambient air. (No elec. Auxiliary heating!). Thus, it takes about 1/2 hour before the air has reached its operating temperature in the drum. The laundry should also have been thrown when fully loaded with 1600 rev / min, because the water container is the program "cupboard dry" almost completely full. The cleaning of the lint filter is easy.
