Abstract: The present disclosure relates to a tumble dryer (1) comprising a housing (2), a rotatable drum (11) in the housing being accessible from a front side (3) of the housing, and a fan arrangement (13) for producing a flow of process air through the drum. A heat pump is used for drying the process air before it enters the drum, the heat pump comprising a condenser (19), a compressor (17), and an evaporator (15). The condenser 19 the compressor (17), and the evaporator (15) are arranged as components in a heat pump unit (43), wherein the heat pump unit is removable from the remainder of the tumble dryer (1) through an opening in the rear side of the tumble dryer housing without separating the components. This facilitates for instance service of the tumble dryer.
