An apparatus for the distillation of vaporizable liquids, for example alcohol, solvents used for the degreasing of metal and the like, comprises a distillation chamber, a heating unit in the region of the bottom of the distillation chamber, a cooling and condensation unit at an upper portion of the distillation chamber and a cold-generating unit. According to the invention, the cold-generating unit is formed as a heat pump with a circulating refrigerant and has a compressor, a cold branch and a hot branch. The cold branch is connected to the cooling and condensation unit of the distillation chamber while the hot branch transfers heat via a heat exchanger to a heat storage device, e.g. a utility water reservoir from which hot water is drawn to heat the heating unit of the distillation chamber.
