The invention discloses a box-free type heat pump hot water device. The box-free type heat pump hot water device comprises a heat pump circulating system and a waterway heating system, wherein the twosystems are coupled through a heat accumulator and a reheating heat exchanger, a phase-change material absorbs or releases a large amount of latent heat in a phase change process to replace a traditional heat storage water tank with a large size, the box-free heat pump hot water device is achieved, in an off-peak electricity period, a compressor drives heat pump circulation working medium to do work, the heat pump circulation working medium heats the phase-change material in a condenser, the phase-change material stores the heat, when a user needs to use water in the peak period of electricity utilization, tap water directly exchanges the heat with the phase-change material which has stored the heat to obtain hot water, and when the water temperature cannot reach the preset water temperature, a heat pump circulat
