We're about to deep-dive into wood-burning stoves and the wonders of the catalytic combustor. Stick with us, and by the end, you'll have all the info you need to make a choice that's tailored to you.

What Are Catalytic Wood Stoves?

Catalytic wood stoves are a modern type of stove designed to get more heat out of wood while reducing smoke and pollutants. They achieve this with the help of a special component called a catalyst.

Catalytic Wood Stove

How Catalytic Wood Stoves Work:

Regular Burning: Just like traditional stoves, they burn wood to create heat. This burning process releases smoke and gases.

Introducing the Catalyst: As the smoke rises, it passes through a unique part called a catalyst. Think of this as a special filter made from materials like platinum.

Second Round of Burning: This catalyst helps the smoke burn again, but at a much lower temperature than usual. So, instead of the smoke needing a super-hot 1100 degrees to burn, it now burns at around 500 degrees.

Benefits of this Second Burn:

  • More Heat: This process pulls out more heat from the wood, meaning your room gets warmer without using extra logs.
  • Cleaner Air: By burning the smoke a second time, fewer pollutants go out the chimney, making it better for the environment.

In simple terms, catalytic wood stoves give you more warmth for your wood and are kinder to the environment.

Pros and Cons of Catalytic Wood Stove


  1. Higher Efficiency: Catalytic stoves are renowned for their efficiency. They utilize a catalyst, often made of platinum or palladium, to lower the ignition temperature of wood gases. This process ensures almost complete combustion, resulting in more heat from less wood.
  2. Cleaner Burn: Due to their ability to ignite the smoke and other byproducts of combustion at a lower temperature, catalytic stoves generally produce fewer emissions. This means a cleaner burn, making them environmentally friendlier.
  3. Extended Burn Times: The thorough combustion process allows catalytic stoves to sustain longer burn times. Some models can maintain a fire for up to 40 hours, ideal for sustained warmth during cold spells.


  1. Maintenance: The catalyst in these stoves can wear out and eventually requires replacement. Additionally, the catalyst can be sensitive to impurities, which means users must be careful about the type of wood and starters they use.
  2. Complexity: Operating a catalytic stove can be slightly more complex due to the need to engage and disengage the catalyst at specific times.

What Are Non-Catalytic Wood Stoves?

In the realm of wood-burning stoves, non-catalytic variants stand as a testament to tradition fused with modern innovation. These stoves employ a straightforward wood-burning process, capturing the essence of classic fireplaces while benefiting from current design enhancements.

Non-Catalytic Wood Stoves

Core Functionality:

  • Primary Combustion: Once the wood is ignited, it undergoes primary combustion in the stove, giving off the initial wave of warmth.
  • Secondary Burn: Modern stoves introduce a fresh wave of air into the chamber, re-igniting lingering gases and producing a secondary combustion. This not only increases the heat output but also delivers a lively and mesmerizing flame display.
  • Firebox Design: The interior, especially the firebox, of these stoves, is crafted to maximize efficiency. By reflecting heat back into the combustion chamber, these stoves ensure that the wood's energy is optimally utilized.

But what about the missing catalyst? This design choice comes with its set of perks and considerations:

Catalyst-Free Design:

  • Durability: With fewer parts that can wear out, non-catalytic stoves typically promise longer life spans and reduced maintenance.
  • Simplicity: For many users, the absence of a catalyst means a more intuitive wood-burning experience without the fuss of managing additional components.
  • Efficiency and Emissions: While they boast commendable efficiency levels, especially the contemporary models, they might fall short of the ultra-high efficiency marks set by some catalytic stoves. Nevertheless, they adhere to EPA guidelines, marking them as an environmentally considerate option.
  • Aesthetic Appeal: The flame patterns and overall ambiance offered by non-catalytic stoves often resonate with those seeking a genuine wood-burning experience.

Pros and Cons of Non-Catalytic Stoves


  1. Simplicity: Non-catalytic stoves, without the added component of a catalyst, are often simpler to use and understand, especially for novices.
  2. Durability: With fewer parts that can degrade over time, non-catalytic stoves may have a longer lifespan with less frequent maintenance needs.
  3. Ambiance: Many homeowners prefer the flame pattern and overall look of a non-catalytic stove, praising its authentic and traditional wood-burning appearance.


  1. Efficiency: While modern non-catalytic stoves are still efficient, especially compared to older wood stove models, they typically don't achieve the peak efficiency of catalytic stoves.
  2. Shorter Burn Times: These stoves can't generally match the extended burn times of catalytic models.
Pros and Cons Non-Catalytic Wood Stoves

Which is Better Catalytic or Non Catalytic Wood Stove?

The answer isn't as straightforward as one might hope. The "better" choice largely depends on what you value most in a wood stove.

  • For Maximum Efficiency: If you prioritize getting the most heat from the least amount of wood and desire longer burn times, a catalytic stove might be your ideal choice.
  • For Simplicity and Tradition: If you want a stove that's easier to operate, requires less meticulous maintenance, and offers a traditional wood-burning experience, a non-catalytic stove might be the way to go.

In conclusion, both catalytic and non-catalytic wood stoves have a rightful place in the homes of many. Your specific needs, preferences, and willingness to maintain the unit will determine which is the better option for you. Whichever you choose, both types promise the cozy warmth and ambiance that only a wood stove can provide.

FAQs: Catalytic vs. Non-Catalytic Wood Stoves

Should I opt for a catalytic feature on my wood stove?

Whether you choose a catalytic wood stove depends on your heating needs. Catalytic stoves excel in providing consistent, long-lasting primary heating. On the other hand, non-catalytic stoves shine as occasional or supplementary heat sources. It's noteworthy that non-catalytic stoves dominate about 80% of the market, attributed to their affordability and commendable average efficiency of 71% (though this can vary between 60-80%).

Do catalytic wood stoves reduce creosote formation?

Absolutely! Catalytic wood stoves are designed for efficient combustion, which translates to more heat output, minimized creosote accumulation, and reduced external smoke emission. This efficiency leads to longer and more even burns. In contrast, non-catalytic wood stoves don't incorporate a catalyst, which can influence their combustion profile.

Do catalytic wood stoves operate at higher temperatures?

Not necessarily higher, but they make better use of lower temperatures. A distinguishing feature of catalytic stoves is the catalytic combustor, reminiscent of a honeycomb structure. This catalyst drastically cuts down the ignition point of smoke: instead of the usual 1100 degrees, smoke combusts within the stove at a milder 500 to 550 degrees, promoting a more efficient burn.

Final Thoughts

Janet H shea - March 25, 2024

We have burned wood as our main source of heating for over 50 years. We have had a Waterford Stanley for 35 years as our only source of heat in our 1500 sq.ft home.
We would like to purchase another cookstove. We live in New York State where there are new regulations regarding wood heating.
Do we limp along with our old stove (we are 75 yrs old) or is there an efficient cookstove that we would feel comfortable purchasing for under $5,000. Do you have a preference or recommendation if what stove we might buy?
Thank you for considering our situation.
