PROBLEM TO BE SOLVED: To provide a warming apparatus which warms hot water evenly as a whole.SOLUTION: A forced circulation type warming apparatus includes temperature sensors at a high and low temperature positions in a warming container. When a temperature difference indicated by the temperature sensors is equal to or higher than a desired temperature difference, the forced circulation type warming apparatus forcibly circulates hot water through a circulation pipe connected to the high and low temperature positions from one to the other of the high and low temperature positions in order to make the temperature difference equal to or lower than the desired temperature difference. |
