Phase change energy storage electric water heater and electric heating stove all-in-one machine and heating device thereof

The invention discloses a phase change energy storage electric water heater and electric heating stove all-in-one machine and a heating device thereof. An electric water heater and electric heating stove all-in-one machine outer shell, a heat preservation isolation layer, an inner container shell, a flat plate type plane heating body, a graphene carbon nano heating pipe, a heating pipe fixing upper and lower cover plate, an inner container shell upper and lower cover plate, a silica gel sealing gasket, a temperature sensor, a heat exchange coil pipe, a graphene carbon nano heating pipe protection shell, a phase change energy storage medium, a circuit control system and the like are included. By utilizing the heat and energy storage characteristic of the phase change heat and energy storage medium in the process of converting from a solid state to a liquid state, the storage of electric energy at night is realized, and the electric energy is released and used in the daytime. The phase change energy storage ele
