Abstract
A method and apparatus for filling a steam chamber. In one exemplary embodiment, a steam chamber is placed in selective communication with a vacuum pump and a heat transfer medium, such as a source of deaerated water. The steam chamber is then placed in communication with the vacuum pump, which draws a vacuum on the steam chamber and begins removing air from the interior thereof. Once a sufficient vacuum has been drawn on the steam chamber and substantially all of the air removed therefrom, the steam chamber may be placed in communication with the heat transfer medium. In one exemplary embodiment, the heat transfer medium is deaerated water. A predetermined amount of heat transfer medium is then allowed to fill the steam chamber. Once the predetermined amount of deaerated water has been received within the steam chamber, a steam chamber may be sealed.
