Water treatment?

Does anyone add anything to the water in their storage tank? I have hard water and am worried about clogging up the flat plate heat exchanger. Would water softener salt help?

Should I be worried about corrosion? I have aluminum fin tube and copper heat exchangers submersed in hot water-that sounds like a recipe for some type of corrosion but I don't know what to do about it. I've thought about a zinc sacrificial anode like they use for outboard motors.

Any ideas would be appreciated.

PH is critical. Make sure your water is between 8.2-8.8. If not, you can add 2 lb.s of baking soda to a tank of 600-1200 gal. Watch out for electrolysis. An annode would help. The only real way to know is to have your water analyzed professionally.

Reggie your gonna give you family leprosy.

I bought a couple small anodes and put them in the tank. I'll keep an eye on them to see if they get eaten up. One was magnesium, one was zinc.

ABG-
They may get leprosy, but they'll be the warmest lepers around.

hehe a warm leper is a happy leper
