(and Have Peace of Mind!)

Would You Drive Your Car Without Oil?

Of course not! So you should never operate your outdoor wood boiler without water treatment. You will NOT realize how badly you are damaging your outdoor wood burning boiler without corrosion inhibitor water treatment UNTIL IT IS TOO LATE!

You won't know whether your water is properly treated without sending a water sample to our Lab for your FREE Water Testing and Analysis.

We have a special section of our website dedicated to answering questions about the FREE Water Test and why you MUST do this. You can access this info from our home page HERE:

Here are a few excerpts from the "Free Water Testing Info" section of our website:


The OutdoorBoiler.com Laboratory has expensive testing equipment that provides a sophisticated analysis of your outdoor wood burner water. Those test results are then run through a computer algorithm that provides you with a customized report so that you can have peace of mind knowing that your investment is properly protected.

If your water test results are not satisfactory, this algorithm will give you specific instructions on what needs to be done. In some cases, more water treatment is needed, and in other cases, some sediment may need to be flushed from your system.

Regardless, you will be provided specific and simple instructions on what steps to take.

Why should I use Water Treatment?

Good question! Remember that water starts to eat holes in steel immediately upon contact (through rust corrosion) UNLESS the water is properly treated with a special chemical that has been formulated to protect the exact grade of steel in your furnace -  Outdoor Boiler Certified Liquid Armor Water Treatment! 

You have made a major investment in your outdoor wood furnace, and you want it to last! Liquid Armor Water Treatment helps you protect your investment so that you can save thousands of dollars each year on your heating bills for decades!

What happens if I don't use Wood Boiler Water Treatment?

You have made a major investment in your Outdoor Wood Stove. Just like when you purchased your car, you made this big investment expecting to get many years of benefit from it. Of course, you would never drive your car without oil in the engine... But yet some people are killing their furnaces by operating them without properly protecting the steel from corrosion. 

Untreated furnace water will start to eat holes in steel immediately upon contact UNLESS the water is properly treated with a special chemical that has been formulated to protect the exact grade of steel in your furnace - Liquid Armor Outdoor Boiler Water Treatment! 

This is bad news because if you don't use the proper water treatment, your furnace steel will quickly corrode and become paper-thin. Then, in just a short time, the steel will deteriorate and begin to leak, and your investment will be lost.

It would be like buying a new car, and driving it without oil in the engine...it is only a matter of time and the investment will be worthless.

Here is some good news: If you have not been using the proper water treatment, it is never too late to start protecting your investment!! Start now and extend the life of your furnace.
