1. A hot water supply tank comprising:
a case forming an appearance of the hot water supply tank;
a heating container accommodating a fluid and having an inner side treated with anticorrosive;
a heater installed on at least a side of the heating container and transferring heat to the fluid, the heating container being configured to have a first ratio of a side height to a bottom diameter of the heating container to maximize a heat transfer performance of the heater, and the heating container including a heat transfer area occupied by the heater; and
a heat insulator interposed between the case and the heater,
wherein the first ratio of the heating container has a value inversely proportional to the heat transfer area when the heat transfer area is less than a first area,
wherein the first ratio of the heating container has a value proportional to the heat transfer area when the heat transfer area is greater than or equal to the first area,
wherein the first ratio has a value of 4 to 9 and the heat transfer area ranges from 0.6 to 1.8 m2,
wherein in a case that a volume of the heating; container ranges from 180 to 220 L and the heater is installed only on the side of the heating container, the first has a value proportional to the heat transfer area when the heat transfer area is more than or equal to 1.2 m2, and
wherein in a case that the volume of the heating container ranges from 180 to 220 L and the heater is installed on a bottom as well as the side of the heating container, the first ratio has a value inversely proportional to the heat transfer area when the heat transfer area is less than or equal to 1.2 m2.
