A combined safety shower and eyewash station utilizes steam to heat water in a heat exchanger. Cool water is combined with heated water from the water outlet of the heat exchanger by a temperature-regulated mixing valve. If the water at the water outlet of the heat exchanger becomes too hot, some of the water is fed to the steam inlet of the heat exchanger. This makes it easy for the mixing valve to regulate water temperature even though the shower uses water at a much higher rate than does the eyewash station. Steam is fed to the heat exchanger through ...
Apparatus for delivering water at a controlled temperature comprising: a heat exchanger having a water path, a steam path separate from the water path, and means for transferring heat from the steam path to the water path, each said path having an inlet and an outlet; means for feeding cool water from a water supply to the inlet of the water path of the heat exchanger; means for feeding steam to the inlet of the steam path of the heat exchanger; means providing a by-pass path for the flow of water from the outlet of the water path of the heat exchanger t...
