ABSTRACT:
A novel liquid heating apparatus is provided by which sufficient heat efficiency is achieved with the production cost reduced by simplification of the construction thereof, and the maintenance of which is easily carried out. The liquid heating apparatus is provided with a burner unit disposed downward of the bottom portion of a liquid tank formed to be a rectangular parallelpiped in its plan view for raising the temperature of the liquid in the liquid tank by heating the bottom portion of the liquid tank using a burner of the burner unit. A heating plane opposite flame ports of the burner and a low temperature portion located downward of the heating plane are formed at the bottom portion of the liquid tank. Fins protruding toward the burner direction are juxtaposed and fixed on the rear side of the heating plane in the lengthwise direction thereof. A fan capable of generating a flow of combustion gas among the fins is provided in the burner unit. In the burner unit, a plurality of rows of flame ports located along the lengthwise direction of fins are provided at one side in the lengthwise direction of the burner unit. A burner in which a fan is provided is also disposed therein. Furthermore, an exhaust portion is disposed at the other side therein.
