Vented vs Ventless Gas Logs - US Fireplace Store

Vented vs Ventless Gas Logs

Which one should you choose and why?

If you love to try the warmth of a real fire, but with a touch of modernization (no hassle of managing and stoking natural burning wood), then a gas fireplace is what you should probably start shopping for. 


Like everything nowadays, there are always options, options, and options that you must choose from. In this case, you must pick between a vented or ventless gas fireplaces. 


Fear not! We here at US Fireplace Store would love to help you out. Let us discuss the pros and cons, and hopefully, by the end of this article, you would already be able to choose which one suits you and your home best. 


Vented Gas Logs Pros


Vented Gas Logs has a lot of stars on its advantage columns. Let us discuss what we think are the top three reasons why it is a great choice:


  • Easy Installation for Those That Already Has A Fireplace and Chimney
  • Customers who already got a working fireplace and chimney would choose a vented gas log since it can be installed with no further construction or remodeling needed. The installation process is easy-peasy! 

    Of course, it is essential to note that the chimney must be working since vented gas logs make carbon monoxide. If you choose this type, you must make sure that the fumes are vented outside for safety. 


  • Aesthetically Pleasing
  • If you wish to have a fireplace that looks like it was taken directly out from Pinterest, then vented gas logs would be best for you. The fire it produces looks so realistic but without the mess of the wood version fireplace. It also adds to the allure that the vented gas log’s flame mimics the same dancing motion fire does on natural burning wood. 


  • It Won’t Break the Bank
  • Market prices show that vented gas logs are much more affordable than ventless gas logs. As mentioned above, if you already got a working fireplace and chimney, the installation is a breezy process, meaning the labor cost for installing it is much cheaper. So, for people who don’t want to spend much on upgrading to a gas fireplace, the vented gas logs are the better choice. 


    Vented Gas Logs Cons


    Since we discussed the advantages, we must also tackle the disadvantages of buying vented gas logs. Here are the top three: 


  • Working Fireplace and Chimney Is Not an Option – But a Must
  • Previously, we discussed how vented gas logs can save a lot of money and time for people who already got a fireplace and a chimney. Well, how about those who don’t have them available already? They cannot have a vented gas log set unless they have a fireplace and chimney built and installed from scratch, which would be expensive and time-consuming. 


  • Vented Gas Log Is Not for Efficiency 
  • Unfortunately, for people whose primary reason for getting a fireplace is for it to be a primary source of warmth for their place, then the vented gas log would disappoint them. A good portion of the heat that it produces goes out the chimney. 


  • It Consumes More Gas
  • As mentioned previously, a vented gas log uses a chimney, and a lot of the heat it produces gets wasted, so it needs more gas than its counterpart. In the long run, it can be pretty expensive. 


    Ventless Gas Logs Pros


    Since we already discussed the pros and cons of the Vented Gas Logs, it is time to talk about its rival in the market. Here are the best reasons why one should choose vent-free or ventless gas log sets:


  • No Need for A Chimney 
  • You don’t need a working fireplace and chimney to install a ventless gas log. It can be installed in a wood-burning fireplace or even in those factory-made fireplaces. Honestly, all you need is a gas line, and you can start enjoying a warm and cozy time in your place. 


  • Quick and Efficient 
  • According to research, Ventless Gas Logs burn so hotly that almost if not all 100% of the fuel is combusted. Due to this, it does not need a chimney or a flute, leading to more heat that provides more warmth. Despite being much more efficient than its counterpart, it is also good to note it consumes less gas, leading to more financial savings in the long run. 


  • Friendlier to Mother Nature
  • I mentioned above that Ventless Gas Logs is extremely hot, that the fuel burns almost completely, which means it produces much less pollution. That’s a significant checkmark on the pro’s column. 


    Ventless Gas Logs Cons


    And now let’s talk on aspects about Ventless Gas Logs that can be a dealbreaker for some:


  • Some Places Can Be Strict About It
  • States like Massachusetts got codes and rules that need to be explicitly followed for Ventless Gas Logs before installation. Meanwhile, in California, ventless gas logs are outright prohibited. So before buying, make sure to check in first the legalities in your state about it. 


  • It is Not as Aesthetically Pleasing
  • Compared to vented logs that look like it belongs to Pinterest, Ventless Gas Logs produce somewhat less realistic looking flames. The color of the fire looks more like the blue you see on the stovetop counter rather than the yellow-looking fire you see on a campfire or fireplace. 


  • Can Trigger Health Concerns
  • Unfortunately, due to its system and how it works, Ventless Gas Logs can irritate the lungs. People with bad allergies and chronic lung issues are much more susceptible to its harmful effects. It can also irritate the eyes and trigger coughing. 


  • Possibility of Grave Risk
  • Ventless fireplaces have sensors specifically for oxygen levels. It will automatically shut off the system if the oxygen in your place gets depleted to the point of being unsafe. Due to this, people must face the fact that it can be dangerous if the system encounters an error or malfunctions. As a fallback, it is recommended to avoid using Ventless Gas Logs longer than an hour and if that is not possible, make sure to crack a window or door for more oxygen access on the place.


    So, which is which? Ventless or Vented Gas Logs?

    After reading about the pros and cons of both options, have you already made up your mind? Is it the ventless or vented gas logs? Remember, to make the best decision, you must weigh in your situation, wants, and needs. 

    Does your place already come with a working fireplace, or is it a modern apartment where there is no chimney and fireplace available? 

    Do you prefer a good source of warmth, or does the ambiance matter more for you? Where do you live? What’s the law about gas logs in your state? There are quite a lot to consider. So, I suggest you take your time and think about it carefully.
