A steam heating apparatus, including a housing, a heater, a water inlet, and a steam outlet. The heater includes a base and a heating body vertically extending down from the base. The heating body includes a water inlet channel, a steam outlet channel, and heating pipes. The water inlet channel and the steam outlet channel are located between a pair of vertical heating pipes among the heating pipes. One end of the water inlet channel is communicated with the water inlet provided at one end of the heater, and the other end of the water inlet channel is opened to allow steam to flow out. The steam heating apparatus can fully utilize the heat of the heater, and the steam conversion efficiency and quality are higher. Meanwhile, the problem of blocking is prevented, and the performance of the heating apparatus is improved.

A water tube is adapted for use in a steamer. The steamer has a steam chamber and a heating plate that is disposed under the steam chamber.
