A liquid heater is disclosed comprising a liquid tank that accommodates liquid used as a heating medium and a pathway through which this liquid flows in and the heated product flows out, a combustion chamber that is installed in the liquid tank and has a wall used to form a separate inner space, and a supply piping that penetrates the wall or connects with the wall to supply fuel and oxygen, wherein the wall has a plurality of fine through-holes or slots. According to the invention, as combustion takes place in the liquid in the liquid tank, heat transfer to the liquid takes place simultaneously using burner gas bubbles and heat transfer through the wall of the combustion chamber, and the size of bubbles can be easily controlled to increase the thermal contact area, and efficiencies of temperature elevation and heat transfer for the entire liquid can be increased by liquid mixing and convection within the liquid tank as a result of the bubbles. |
