Top 3 "Steel Eaters" and How To Stop Them

By:Warren Walborn

My Outdoor Boiler is LEAKING!
And the Steel is Paper Thin! Why??


This is the worst news. We hate hearing this news. Sometimes it means that the outdoor boiler's life is over, and it could have been prevented! 

(We never want to hear this. Our goal at Outdoor Boiler Care is to help you get the longest life possible out of your outdoor boiler. Let us help you EXTEND the life of your outdoor boiler!)


What is a "Steel Eater"?

There are three things that EAT STEEL. These things will make your boiler steel paper thin, shorten the life of your boiler, and PREVENT you from being able to save money by burning wood.  

1. Moist Ash - Ash is harmless when dry and powdery. But if you allow your ash to get deep in your boiler, it will absorb moisture from the wood, and become acid paste. This will eat your steel.

Don't be foolish and think that your wood is different. Some say "I only use seasoned wood." That is great, but even the most seasoned hardwood contains 15-20% moisture - that is a lot of water. A thick layer of ash in your boiler will absorb that moisture, become caustic, and slowly eat your steel.

Solution? Keep your ash level to less than 2 inches at all times. Remove a small amount of ash every day. And once or twice a month, remove ALL the ash and scrape out the firebox bottom with a spade. If you discover ash that appears moist and steamy, your ash level was too deep and you are damaging your steel. KEEP ASH LEVELS LOW!

2. Uninsulated Chimney Extensions - This is the FASTEST way to eat holes in your steel. Again, wood fuel contains moisture and you want that moisture to exit the boiler harmlessly in the form of steam. However, an uninsulated chimney cools the steam and it will condense on the walls of the chimney - this creates the most caustic acidic creosote!  This acidic creosote drips back down into your boiler and eats holes in your boiler very quickly. 

Solution?  NEVER use an uninsulated chimney extension - if you have one, remove it TODAY!  We all have chimney extensions on our boilers and love them - but they must be INSULATED chimney extensions.Click HERE for more info on insulated chimney extensions. They are nice to increase draft and to get the smoke up and away.

3. Untreated Water - Whenever water and steel touch, the steel begins to rust immediately. Steel companies have a spray they apply to their inventory, or else rust forms in one day. 

Your water jacket steel begins to rust the moment water touches it, UNLESS the water is properly treated with Liquid Armor water treatment.

Solution?  It's simple - use Liquid Armor. See below for more details. THEN take advantage of the FREE water analysis and testing by sending a water sample to the lab. Click HERE for the address where to send the sample.
