Your boilers at work should be blown down on a regular basis and

steam boilers as we used a lot of water. Even though softened you still
have to be careful with steam boilers. We operated at 110 psi, over 300
degrees.


The boilers were okay. The boiler had a loop for the building heating system and a loop for domestic hot water. It was domestic hot water that would precipitate deposits in the valves if it got too hot. Obviously you can't do chemical treatment on domestic hot water.


A softener would help.

Sure. But it would be costly to run in a building this big, with 300 showers.
