Would an anode in a hw boiler work?
Would it help prevent any corrosion?

    Hello, I'm a big fan of anodes for water heaters using potable water. The water in your boiler should have little to no oxygen it it however, so I'm not sure an anode would do much good. Anodes produce corrosion byproduct as they get consumed. Also hydrogen gas is generated. I'm guessing those would not be good things to be making in a boiler. ;)

    Yours, Larry

    Makes sense.
    So in a closed hydronic system, that doesn't take on much new water with air mixed in it, an anode is not necessary? it's useful in hw heaters due to the continual addition on fresh water which includes air?

    If you are worried about corrosion assuming it's a closed loop put in an additive. Sentinel makes some great products

    I have used Deionized water in my closed loop systems for years (Chemical free as per the VDI 2035 and the new ANSI H 1001.1)...Generally with Deionized water the PH drops and that is when sacrificial anodes will help keep things balanced..
