Water expands 1,700 times when it is converted to steam. We collect the condensate, which hopefully is still hot, and feed it to the boiler because hot water does not flash to steam as easily as cold water. It is safer and easier on the boiler vessel to use pre heated water to make steam. Cold water going to a hot boiler can be loud and pretty
