WHY DO YOU NEED TO PUT WATER TREATMENT?

Outdoor Wood Boiler Water Treatment - Liquid Armor: Protect your investment! Keep your warranty valid! Treating the water in your outdoor boiler with safe and effective Liquid Armor water treatment is the most important thing you can do to protect your furnace. Liquid Armor is the #1 Outdoor Boiler water treatment because it has been specially formulated to protect the exact grade of steel in your outdoor boiler!

Includes four (4) gallons of treatment, and two (2) water testing kits per gallon (8 kits) so you can submit a water sample to our laboratory for a FREE water analysis and test report.  Each kit includes written instructions, a water sample bottle with lid, and a shipping box with a pre-addressed shipping label. 

All water samples received (regardless of furnace brand) will be tested and a full analysis report will be provided via email within 4 weeks. This report includes instructions for further treatment/testing, but only if required based on your local water conditions.

You may submit as many water samples as you wish, but it is recommended to submit at least one sample every 12 months. If you do not receive a "SATISFACTORY RESULT", please follow the instructions in the test report, and then send another sample. You must have at least one "SATISFACTORY" test result every 12 months to maintain your warranty. Keep a copy of your test results.

Most outdoor boiler warranties require annual testing. This laboratory test report is evidence that you are properly protecting your investment in case you ever have a warranty claim during the life of your outdoor boiler.
