So lately Ive been helping several buddies build water pole fed window washing machines, they consist of a big R.O filter, a carbon filter, a couple gauges and a D.I setup like the caleffi hydrofill.
My research on the Hydrofill has me a little confused hoping you guys can straighten me out. So D.I basically strips the water of many things, and works like R.O in the sense that the water will be quite hungry after it goes through the Hydrofill and will eat copper, steel and other things. So why do we want that in the boiler system?
One thought was maybe on initial fill its ok and it will eat until its happy then stop, but I am a little confused. Hoping someone can dumb this down with lots of word pictures so even I can get it.
Thanks all
Tom
