Although fireplaces have fallen out of favor as the main heating choice for homes, many homeowners still love the atmosphere a warm fireplace can create. Ventless gas fireplaces are easy to use and very clean, and this makes them a favorite with homeowners in small and large houses. You may also hear them called vent-free or unvented, but ventless gas fireplaces work by piping propane or natural gas into a gas unit and they have flames running through artificial logs. Since it can be challenging to install a traditional fireplace due to venting, a ventless gas fireplace is a welcome alternative.
This is an excellent solution to your problems. Not only are ventless gas fireplaces much easier to install than vented gas or wood fireplaces, but they’re also powerful enough to heat smaller rooms in your home while giving you that warm and cozy ambiance you want. No matter if you’re building your new home or looking to remodel, here are 10 of the best ventless gas fireplaces available on the current market.

Best Ventless Gas Fireplace Buying Guide
When you start sifting through products to find the best ventless gas fireplace, what do you really want to keep an eye on? How does this product work and it is a good idea for you to invest in one? No matter if you have a large or small room to heat, making sure that you pick out the best product for your wants and needs is critical to ensuring how efficient it is.
Understanding How Ventless Gas Fireplaces Operate
Contrary to popular belief, you won’t need a lot of time, effort, or tools to install a ventless gas fireplace in your home, and this is the beauty of this product. With this product, the gas unit comes with its own control panel that controls both the flames and the pilot light. It features noncombustible artificial logs with holes drilled into them that slot together in a precise manner. Instead of venting like a traditional fireplace would through a tube or chimney to the outside, this type of fireplace will direct the spent gasses into the room.
The ventless gas fireplace directs the oxygen in a U-shaped path, and the oxygen will then enter through the bottom of the fireplace before venting back into the room through the top. This will help to feed the flames, and there are no emissions to worry about when it runs.
What to Look for in Your Ventless Gas Fireplace
When you start shopping for your new ventless gas fireplace, there are several key features you want to consider. Doing so will ensure that it is powerful enough to heat the area size you want, and that it fits nicely into your space.
The BTUs are a measure on how powerful the fireplace is. The higher the BTUs are, the more powerful your unit is. It’s common for ventless gas fireplaces to have BTUs somewhere in the 20,000s, and it’ll usually list the proper room size right on the box. You can match this to your room and see if it’ll provide enough heat to keep you comfortable.
Most fireplaces list the room coverage capabilities in square feet, and it’s relatively easy to find this measurement for your room. All you’ll have to do is measure the width and the length of the room. Multiple these two numbers together to get the total square footage, and compare what you find to the recommendations on the box. This will give you a good idea on whether or not one product will work for you, and this helps you narrow down your options much quicker.
Remote with Temperature Control Suite
Not all ventless gas fireplaces come with remotes, and this makes it harder to set your desired temperature and control the fluctuations in the room. Look for a unit that has a temperature control suite with a built-in thermometer and a remote that lets you change or set it from anywhere in the room. Check and see if it needs any batteries to run and make sure you buy them when you get your fireplace so you’re not stuck and waiting when you want to use it.
Ease of Installation
Most of the products on my list are very easy to install once you get them. Pay attention to the width and height when you shop, but also pay attention to the depth. You don’t want a product that sticks way out into your room and creates a tripping hazard. It also shouldn’t be too large. If you want to put it in your teen boy’s room, make sure you have adequate space around it for ventilation to prevent fire hazards.
The safety features on your ventless gas fireplaces are key, and this is especially true if you plan to leave it running when you’re not in the room to monitor it. Look for things like an oxygen depletion sensor because this will shut the product off when it senses a lack of oxygen or carbon monoxide buildup. A push-button ignition switch is nice too because it keeps your hands away from the fire.
Ventless gas fireplaces are a nice alternative for anyone who doesn’t have the space or time to install and maintain a traditional fireplace. I’ve showcased 10 great options that will effortlessly heat a broad range of room sizes, and they feature different colors, styles, and sizes. Look and see which one will work best for you, compare products, and have your final choice shipped straight to your door to keep you warm all season long.
