When choosing a wood stove chimney pipe, there are a few things that you should consider. Design and mode of installation is an important factor. Since smoke is generated by an incomplete combustion, you should take into consideration the design of the stove that will provide a complete combustion. Other factors that are undesirable when using a wood stove is low burning temperature so make sure when choosing a wood stove that it is important to have good oxygen flow and a high burning temperature. This way all the fuels are burnt well, without the hassles of smoke.
Baffles is another thing to consider. This increases the efficiency of your stove by increasing turbulence. With low turbulence, wood fuel isn’t burnt properly and becomes just a waste of energy or firewood. The function of baffles is that it holds gases inside the firebox longer and directing them back into the fire so they will burn more fully and make the temperature of the wood stove much hotter. There is also an insulated baffle in which makes the gas temperature higher to produce a much higher temperature.
Air supply is also important. Inside the wood stove chimney, the pipes allow preheating of the primary and secondary air which can fire up to give another form of combustion and ensure that combustion is complete.
Check your wood stove chimney pipe for firebox insulation, also known as firebricks, which stores heat and keep combustion temperature much higher and stable. This insulation keeps your home warm, even after the finger has gone out. When your firebox temperature is higher, this also promotes a more complete combustion.
Certifications and Emission Standards
Also take into consideration certification and emission standards of your wood stove. A household cannot just install any wood stove chimney pipe because this can be a fire hazard and might be emitting more smoke or dangerous gases than it is supposed to. Wood stoves’ exhaust has to be well regulated because it comes with a lot of hidden dangers that one may not be aware of.
The U.S. Environmental Protection Agency, or EPA, regulates wood stoves in the United States. All wood stoves must be tested for the quality of their emission to know the level of particulates they produce. Though a lot of people still makes their own wood stoves, there are stoves that cannot be sold to the public if the level of particulates are not up to par with the EPA standards.
Since secondary combustion is an important factor for a wood stove to be efficient, most wood stoves in the market already have this feature. And because of this, most wood stoves in the market now have a feature wherein dangerous chemicals and toxic substances are eliminated inside the firebox, before it is exhausted into the heating vents of the homes.
Always remember that the 3 keys features to look for in a wood stove chimney pipe are its adequate oxygen supply, high burning temperature and enough time for the gases to burn before they cool down.
