Abstract
A fluid heating device includes: a tank to store a fluid; a pump to deliver the fluid stored in the tank; a heater to heat the delivered fluid to a predetermined temperature; a return pipe to return the heated fluid to the tank; a fluid supply valve to supply an unheated fluid into the tank; a fluid discharge valve to discharge the heated fluid from the tank; a temperature sensor to detect a temperature of the heated fluid; and a temperature controller to control an opening degree of each of the fluid supply valve and the fluid discharge valve to control the temperature of the fluid stored in the tank. The temperature controller includes: a discharge opening-degree controller-to control the opening degree of the fluid discharge valve; and a supply opening-degree controller to control the opening degree of the fluid supply valve.
