The water inlet end of the heating coil is connected with the water tank, and the water outlet end of the heating coil is provided with a water outlet tap and an exhaust pipe. The exhaust pipe is connected with the water tank. When in use, bury the heating coil in the earthen stove, add water to the water tank, and when the faucet is turned on, the water flows from the water tank to the heating coil and then to the faucet. When the water flows through the heating coil, it is heated by the heat generated by the earthen stove. The generated water vapor is discharged back into the water tank to be condensed so as to heat the water in the water tank. The earth stove water heater can obtain free hot water in the vast rural areas where the earth stove is used, and makes full use of the heat released by the earth stove.
