I was a boiler designer in my early days.
The purest water is required for boilers!
A good potable water will contain between 50. and 400 ppm of TDS ( Total
Dissolved Solids), where as high pressure boilers can not tolerate more than
0. 02 ppm for the boiler-to work well! In addition to limits on solids , the
boilers can not tolerate more than 0.007 ppm of disolved gases.!
