ChemWorld Boiler Rust Inhibitor - Wood Boiler Chemical - 1 Gallon - Treats 250 to 500 gallons of Fresh Water

I have a 9 year old outdoor wood boiler. I've been using this product for a few years with the convenience of ordering from Amazon. I drain and flush the system every couple years and begin by adding about 1/2 gallon of treatment to the system. Every year, I add another 1/2 gallon or so to the system when I top off the water level. I seem to get much less rust and corrosion coloring when I drain and flush the system.

I like that we paid less than half what our dealer sales it for. If you have an outdoor wood stove this is a must have. You test your water every year, by sending a sample to the company and the company that produces your stove lets you know when you must add more chemical. This keeps your 12,000-dollar stove from rusting from the water it needs to operate. So glad we found this on Amazon. Will definitely buy more when we need it. High quality chemical and yes it turned pink. Great value and I highly recommend.

Works great been using for year's

I like this product very much, it was use in my outdoor wood boiler.

Our outdoor woodstove needs drained and rust inhibitors added as maintenance and the name brand rust inhibitors has gotten so pricey, want to keep up on maintenance to keep it running smoothly so looked for another option. This is the first year of using so can’t speak for longevity of it m, guess only time will tell but so far so good.

Works good

Works as it supposed

I am a science teacher and taught chemistry for several years. I looked for a while about the "magic" ingredients in anti corrosion agents for wood burner/boilers. I couldn't find what was used and certainly don't want to damage a very expensive wood burner to save a few bucks. This was a cheaper product, that I am trusting will do what is says. In reading the reviews, I'm not sure how someone can rate it high without testing how much corrosion has taken place over a certain period of time. This is one of those products that requires independent testing and reporting like Consumer Reports. My system cost me 10 grand 15 years ago. That was also the last time I added anti corrosion agent. I have never noticed rusty water, so I am assuming all is well. I am confident this product will do the same.

Good

Expensive so I hope it works
