I have a Weil Mclain gas steam boiler (~1992-1993). After I purchased the house the automatic water feeder never worked. (automatic feeding function, manual push-button feed works fine). In the past I normally manual fed once every two weeks. But starting from last winter I had to put water more and more frequently. Now I almost have to put water every 24 hours.

In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated and changes to steam, free oxygen is released, carbon dioxide is released from the solids, and the solids drop out (precipitate). 2.2.3 As the steam is used in the end process, it cools and condenses
