Water heating blanket and heating water circulation system

The invention discloses a water heating blanket. The water heating blanket comprises a water flow channel and a phase-change material channel which are densely distributed in the water heating blanketbody. The water flow channel and phase-change material channel are parallelly arranged, and locked and fixed by hoops. Circular heating water is flowed in the water flow channel, and the phase-changematerial channel is internally provided with a phase-change material and a heating wire for heating. The beneficial effect of the water heating blanket is that the potential safety hazard caused by the breaking and burning of the heating wire can be avoided because the water heating blanket insulates and stores the heat based on the phase-change material, and the energy is saved and the consumption is reduced because the water heating blanket takes part in the large circulation of the heating water in a water heater and a heating system. 本发明的水暖毯，包括密布于水暖毯毯体内的水流通道和相变材料通道，所述水流通道与所述相变材料通道并排设置，并由卡箍卡紧固定，所述水流通道内有循环的采暖水流动，所述相
