1. A liquid heating apparatus for heating a liquid that is supplied in a liquid supply direction through a supply route to a liquid droplet ejection head, the liquid heating apparatus comprising:
a liquid chamber disposed upstream of the liquid ejection head in the liquid supply direction and disposed on the supply route of the liquid and configured to temporarily store the liquid supplied from a liquid tank; a temperature-adjusting flow path disposed downstream of the liquid chamber in the liquid supply direction, the temperature-adjusting flow path including a predetermined length having a serpentine shape configured to heat the liquid supplied from the liquid chamber, the liquid flowing in the liquid supply direction through the predetermined length having the serpentine shape from one end of the predetermined length having the serpentine shape to the other end of the predetermined length having the serpentine shape; a housing to house the liquid chamber and the temperature-adjusting flow path; and a heater surrounding the liquid chamber and surrounding the temperature-adjusting flow path, to heat both of (i) the liquid chamber and (ii) the temperature-adjusting flow path including the predetermined length having the serpentine shape through which the liquid flows from one end of the predetermined length having the serpentine shape to the other end of the predetermined length having the serpentine shape.
