Why Water Quality is Important When Using a Steam Autoclave

No. Deionized and distilled water has been stripped of all minerals which means it has no electrical conductivity. Consolidateds standard (carbon steel) steam boilers use conduction-based water level sensors which means that boilers fed with deionized water can cause intermittent failures.

How to Destroy a Boiler -- Part 1

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes the water temperature increases and it rises to the boiler steam drum.
