Many homeowners depend on wood-burning stoves for heat. And if your heating stove is more than 15 years old, you are probably wondering when it will need to be replaced. Keep an eye out for one or more of the following warn signs that indicate it’s time to replace your wood stove.
It was manufactured before 1995
If you have a wood stove that was manufactured before 1995, its time to consider a replacement, older wood stoves are not as efficient and produce a lot more pollution than newer models.
In 2015, the EPA made the most significant changes since 1988 with the introduction of Step 1 of the revised performance standards. The new rule requires manufacturers of wood-burning stoves and heaters to emit no more than 4.5g of smoke per hour.
It was a significant reduction in pollution compared to old stoves that release up to 30 grams of smoke per hour. And to meet these strict new government standards, wood stove manufacturers made significant changes to its internal design. As a result, more modern EPA-certified wood stoves are more efficient, burn cleaner, and are easier and safer to use.
Signs of warping or cracking
Many wood stoves are built to perform for decades. But the lifespan of your wood stove will largely depend on the quality of materials. While most woods stoves are made from steel or iron, the grade of these materials and quality of workmanship will largely determine the life expectancy of your model. In the last 20 years, imports have flooded the market. Many of these imports use lower grade materials. Although wood stoves that are made from iron or steel are designed to withstand a regular wood-burning operation, the repeated heating and cooling can eventually cause warping. Also, excessive creosote inside the stove can cause a fire. The extremely high temperatures can also cause the stove to warp, and you may notice some cracks near the bolts or welding.
If your wood stove is showing signs of warping or cracking, it is no longer safe to use and should be replaced.
It produces a lot of smoke
A small amount of smoke is reasonable, especially when starting a fire. But if your wood stove is producing more smoke than normal, your stove may have problems that need a total replacement. The baffle plate or catalytic combustion may be damaged, and there could be water leaks or other damages. A smoky stove is also very inefficient to operate and produces much less heat. Since smoke also causes excessive pollution, including creosote, it’s a sign that it’s time to replace your heating appliance.
Older wood stoves are not clean burning devices and require frequent cleaning to prevent the accumulation of creosote and other residues. And if it’s been quite some time since your last stove cleaning, there may be an excessive accumulation of creosote, soot, and other debris in the stove, stovepipe, and vent. Creosote is the primary cause of residential fires. A fire that starts in your stove can quickly spread to your stove pipe and other combustibles throughout your home. So, if you have a lot of creosote in your stove, it’s time to switch to a cleaner-burning EPA-certified wood stove.
You need to use more wood fuel than in the past to get the same level of heat
If your stove is consuming more wood fuel than before to maintain the desired heat, then there may be issues with its heating efficiency. The performance of your wood stove can degrade over time due to warping, air and water leaks, and other problems. Replacing an inefficient wood stove with a newer model will reduce your energy costs. Newer EPA-certified models produce up to 50 percent more heat while consuming 1/3 less fuel.
