Never Operate Boiler at Temps Below 140 F

Never Operate Boiler at Temps Below 140 F

Since even the most seasoned hardwood contains 20 percent moisture, burning wood requires eliminating this moisture. In normal operations, we want that moisture to exit the furnace harmlessly in the form of steam. 

However, some of that steam will condense if ash levels get deep, and most critically, if the water jacket temp drops below 140F, then substantial amounts of condensation form, which leaves a thick layer of creosote. Learn more by watching the video on this topic HERE.

Use Properly Seasoned Wood 

Your firewood should be seasoned. Green wood contains far too much moisture (up to 50%) and does not burn well. High moisture content wood requires up to 40% of the heating value of your wood just to burn off the moisture and convert it to steam. This is heat that otherwise would go into your home.

To properly season firewood, it must be cut, split, stacked, and covered on top, but not on the sides so air can flow through the woodpile. Many customers report that after 6-9 months, their wood is properly seasoned. This means that you must prepare your wood NOW for the upcoming 2022-2023 heating season.
