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.


Pay me now or pay me later. What is the cost going to be clearing the
pipes of 300 showers? How well do the shower heads work? Dishwashers?
Softeners cost little to operate once installed. I bought 50# bags of
salt for about $9 delivered in volume. We treated enough for up to 400
gallons and hour. We did it to save money!
