Chemicals

Henry

Building owners, if a chemical salesman shows up at your door, DON'T let him in! They are the biggest problem in the steam industry. There is NO reason to have ANY chemicals added to a heating boiler if you have good water and a water softener.

Here is another example of what happens when you ad chemistry to a heating boiler. In this case there was so much added that there was chemistry into the header which ate the threads on all threaded fittings. The front section is scrap as well as the rest of the boiler has at least 1/8 of an inch of scale inside. BTW, look a the schoolboy install of a closed ball valve on the equalizer

don't forget that salt from water-softeners can also make some big problems.'i still wonder if reverse osmosis water could be used in boilers to prevent scale.--nbc

Culprits

Here in the Great White North, salt from softeners are really not a problem. The culprits are the voodoo medicine man selling chemicals and the know-it-all that says you don't need any blow-downs! The last know-it-all cost his boss 26 tubes on a year old boiler! Conductivity was at 15,000! The water was black with iron.
