1. Add Chimney Extension
A chimney extension slows air flow through your outdoor boiler and thus improves efficiency because heat stays in the boiler longer. These items are available at our online store by clicking this link HERE. We recommend the 8x48 for HE models and the 6x48 for GX models. Remember that HE furnaces require a chimney adapter to add the extension.
2. Replace Blower Fan
Blower fans that are older than 5 years old will begin to lose their effectiveness and may not be performing at their optimal power or CFM (cubic feet of air per minute). We recommend replacing the blower fan if you are experiencing poor efficiency for undiagnosed reasons.
AT LEAST, we recommend having a spare blower fan on hand for when your fan dies, which will inevitably happen during the first 10-20 years of your furnace life. Click HERE for our blower fans and learn more.
3. Cover Your Wood
If your wood pile is not covered, you likely have snow, frost, and ice all over your wood. As temps rise above freezing, there may be considerable rain making your wood moisture content high. It is never too late to cover your wood pile with a tarp, which enables the wood to dry and make your burn more efficient.
Wet wood will burn in your boiler, but many of the BTUs produced from the burning of your wood fuel are wasted because that energy is required just to burn off the water and convert it to steam.
Cover only the top of your wood pile so air can flow through it from the sides and dry out the wood.
4. Completely Clean the Ash and Creosote From Your Boiler
To get the most out of your wood fuel, you want the heat from the wood to transfer into your water jacket. But a dirty furnace is less efficient.
If the walls of your boiler are covered with thick black creosote, much of the heat from your wood will not transfer to your home, but will just go out the chimney and be wasted.
This can be prevented by putting a creosote stick on your fire once per week. These cost only $3.75 and are available in a 5-pack HERE.
Also, deep layers of ash will prevent heat transfer of BTUs from your wood fuel into the water jacket. So, keep the ash layer to one inch or less.
Also, make sure your chimney, heat exchange tubes and deflector plate area are clean - deep layers of ash in these areas will prevent proper air flow which reduces efficiency also. Cleaning brushes are available at the "Cleaning Supplies and Tools" section of our website HERE.
These TIPS will not only help you conserve wood, but this also helps you save more MONEY, and WORK LESS so you have more time with your family and hobbies!
