A steam generating apparatus includes a body for receiving water to be heated and has a first portion including a first metal, and a heating device having a second portion including a second metal. The heating device includes a heating plate connected with the body by forming an intermetallic layer
A steam generating apparatus includes a body for receiving water to be heated and has a first portion including a first metal, and a heating device having a second portion including a second metal. The heating device includes a heating plate connected with the body by forming an intermetallic layer between the first and second portions. A temperature sensor measures temperature indicative of pressure inside the body and thermally contacts the heating device outside the body. A method of controlling the pressure of steam in the steam generating apparatus includes setting the target water temperature for a first time period to a first set temperature; setting the target water temperature for a second time period to a second set temperature higher than the first set temperature; and setting the target water temperature for a third time period to a third set temperature lower than the second set temperature.
