Outdoor Furnace: Why Everyone Loves and Needs Chimney Cap
Using Chimney caps on outdoor wood boilers is NOT optional. These chimney caps are a very high-tech designed product that provides three critical functions:
1. Keep the rain out - This one is obvious.
2. Spark arrester - Depending upon the wood you burn and local wind conditions, you do not want sparks leaving your outdoor boiler and igniting your woodpile or anything else nearby. The chimney cap is a spark arrester and knocks down any sparks that get out the chimney.
If you have combustibles near your outdoor wood furnace, we also recommend at least one length of "Chimney Extension" and an "Extension Adapter" to further eliminate the risk of having a fire.
3. Prevent downdraft - If you ever have high winds (and who doesn't!), the special design of the chimney cap will prevent high wind from sucking heat out of your boiler and adding air to the fire, particularly when the furnace is in the idle mode when you don't want the fire to burn.
This can severely damage your outdoor wood burner steel if the furnace fire continues to burn when it should not.
So please remember that chimney caps are NOT optional equipment for outdoor wood burning boilers. They are required and provide very important functions that enable you to continue to save money on your heating bills for decades!

SOME FREQUENTLY ASKED QUESTIONS:
Can I burn green wood?
- Green wood has more moisture than seasoned wood. The more moisture in the wood the more water the furnace must work to eliminate. The water accumulates on the walls of the furnace which allow creosote to build up quickly in the furnace.
Why do I need a water filter?
- The water filter removes particulates from the water. These can build up in the heat exchangers, causing them to work less effectively, & can clog the exchangers.
Water cleanliness is important to reduce erosion within your water system. Debris such as dirt or rust particles should be filtered or flushed from the water system.
Why is water treatment important?
- The chemical (water treatment) coats the inside of the furnace to reduce the effects of corrosion on the metal.
What do you mean by proper ash management?
- If the ash becomes wet it is corrosive to the metal of the furnace. If the level of ash is too thick in the water box it does not allow for efficient heat transfer to the water in the water jacket of your outdoor wood burner. The temperature of the water in the jacket is used to heat your house.

Free Water Testing
One of the most important steps in prolonging the life of your outdoor boiler is to ensure that the water in your boiler is not corroding the steel. Water starts to eat holes in steel immediately upon contact (through rust corrosion) unless properly treated. We test your outdoor boiler water for free! Learn more.
