This application discloses an integrated water purifier and heater, including a filtration unit, a room temperature water tank, a hot water tank, and an instant heating device. The instant heating device is located inside the hot water tank. The filtration unit filters raw water into pure water and delivers it to the room temperature water tank. The hot water tank has a water inlet, through which the room temperature water tank can replenish water. When replenishing water from the room temperature water tank to the hot water tank, water in the hot water tank is forced into the instant heating device.

The water inside the instant heating device is in a constant-temperature state, effectively shortening the preheating waiting time, and the set temperature can be quickly reached in the initial stage of water output.
