I built my own outdoor hotwater wood heater from mild steel and I am looking for something to add to the water for anti corrosion. To buy the commercial stuff is 30 dollars a gallon. My stove holds 275 gallons.

Would auto anti-freeze work? I don't know, just an idea. Or maybe one of those anti-rust additives you add to antifreeze. Antifreeze is about $3 a gallon, not $300 and a 50/50 mix should stop rust.

Talk to you later.

Sorry, meant to write $30, not $300 in the last line of my post.

I am asuming that this water is going to be used for domestic needs so any additave would need to be human friendly. There might be an alternative to rust via an electrical source. There is some kind of device that gives off a micro currant used to protect billboard signs from corrosion (sp)but you will need to get the info from someone more versed in electronics than me.

I've got this stuff that costs $10 for enuf to treat 250 gallons. Its a powder that you mix in the water. Its an oxygen scavenger and rust preventative.

I sell a line of outdoor wood furnaces and 1 gallon of boiler treatment will treat 300 gallons, I would recomend you flush your system yearly and retreat for best protection.
