Are Ventless Gas Fireplaces Safe?

All ventless gas fireplaces are rigorously tested in laboratories to ensure they meet federal health and safety requirements before reaching the market. 

Most ventless gas fireplaces come equipped with built-in ODS, short for oxygen detection sensors, and carbon monoxide (CO) detectors. The oxygen sensor can automatically shut off your fireplace should the oxygen levels in your room dip to a dangerously low level. The CO detector will also shut off the fireplace if it picks up carbon monoxide. 

Pro Tip: While ventless gas fireplace safety requirements are highly regulated by government agencies and come with built-in monitors, installing a third-party carbon monoxide detector in your home is recommended.

Ventless Gas Fireplace Safety Tips

1. Keep Combustible Materials Away From The fireplace

Do not allow Combustible Materials adjacent to or in contact with the fireplace. Combustible materials include wood, compressed paper, plant fibers, or other materials that will burn. These materials are considered combustible even when treated with fire-retardant chemicals.

2. Alert children and adults of hot surfaces.

 

Warn children and adults to stay away from the fireplace to avoid burns and clothing ignition

3. Supervise children.

Keep an eye on your children when they are in the same room as the fireplace.

4. Do not place flammables on the fireplace.

Do not place clothing or other flammable material on or near the fireplace.

5. Install a Carbon Monoxide Detector

While ventless gas fireplace safety requirements are highly regulated by government agencies and come with built-in monitors, installing a third-party carbon monoxide detector in your home is recommended.

Ventless Gas Fireplaces vs. Other Types of Fireplaces

As temperatures begin to dip and leaves start to fall, few things create a warm and inviting atmosphere faster than gathering around a fireplace. Fireplace lovers have more options than ever before, so we've put together a brief guide to walk you through the different types of fireplaces available. 

Wood-Burning Fireplaces

Traditional wood-burning fireplaces have been around for hundreds of years. They usually consist of a brick or metal firebox and a chimney, though specific models use a vent in place of the conventional design. Unlike ventless gas fireplaces, they do produce smoke, smell, and emit dangerous particles into the air. 

Pros:

• Fires are long-lasting if they are fueled properly
• It's easy to find wood chips and logs
• The scent of a traditional fire is comforting
• They are commonly found in many older homes

Cons:

• Most of the heat created by the fire will be lost, so they are not energy-efficient
• They require regular maintenance to remain safe and functional
• The smoke and emissions produced can be harmful
• Some homeowners associations have banned the use of wood-burning fireplaces

Electric Fireplaces

While they don't produce a real flame, electric fireplaces add warmth and ambiance to your home. Some even come equipped with the option to change the color of the electric flames depending on your mood or seasonal changes. However, many ventless gas fireplaces have an advantage over electric fireplaces because they work during power outages. 

Pros:

• More affordable to buy and install
• No cleanup or maintenance required
• Some models can be moved from room to room
• No smell or air pollution because hey don't burn any form of fuel
• Great for zone heating and capable of heating small rooms
• Flames work without heat for year-round use
• Safe for pets and small children because they stay cool to the touch and there is no real flame

Cons:

• They can cause an increase in your electricity bill
• They won't provide heat or light during a power outage

Vented Gas Fireplaces

Like ventless gas fireplaces, vented fireplaces require a gas line connecting to natural gas or a propane reservoir. Because they need a vent, they are better suited to homes with pre-existing chimneys and vents, as the cost of installing one is high. 

Pros:

• The cost of fuel is relatively inexpensive compared to solid fuels like wooden logs
• They can warm your entire home depending on its size 
• Many different designs are available, so you'll find something to suit your style
• There are remote controlled and continuous flame options available

Cons:

• As with wood-burning fireplaces, they lose heat through the vent and aren't energy-efficient
• Chimneys and vents need regular inspections to remain operational
• Unless your home has a pre-existing venting system, one will have to be installed
• More expensive installation, not possible in hi-rises, some condos or brick homes

Alcohol (Ethanol & Gel) Fireplaces

One of the cleanest burning fuels available, alcohol produces a substance similar to human breath, as it consists primarily of water vapor and carbon dioxide. Like ventless gas fireplaces, alcohol fireplaces don't require a vent or chimney. 

Unlike with ventless gas fireplaces, there are no gas lines, which means alcohol fireplaces can be installed literally anywhere. However they do require additional fuel to operate. Alcohol fireplace fuel comes in gel or liquid form, and it is made of Isopropyl alcohol and Ethanol alcohol. 

Pros:

• Alcohol is a clean-burning fuel, so they are eco-friendly
• They do not require a vent or chimney
• Since they don't require vents or gas lines, they are portable
• They don't produce any waste like ash or creosote

Cons:

• Alcohol based fuel is more expensive than natural gas
• You will need to use more alcohol to heat your space because it doesn't get as hot as gas
• Alcohol gels and liquids are not as readily available as other fuels

Water Vapor Fireplaces

Like ventless gas fireplaces, water vapor (also called steam) fireplaces don’t require a vent or chimney.  They operate using simple tap water and electricity to release a fine mist into the air. Perfect for homes with pets and small children, the realistic flames produced by a water vapor fireplace are cold to the touch.

Pros:

• They can be installed anywhere because they don’t require a vent 
• They produce the most realistic imitation flames
• Because the flames are cool to the touch, they are safe for pets, children, and commercial spaces
• Water vapor fireplaces don’t produce harmful emissions

Cons:

• Because they run on electricity, they can’t operate during power outages
• They slightly increase air humidity which can be a concern in already humid climates

Pros and Cons of Ventless Gas Fireplaces

A 20,000 BTU fireplace can heat up to 1,200 square feet, and because most don't require an electric pilot light, they're a fantastic addition to your home during power outages. 

However, there are a few potential downsides to consider before installing a ventless gas fireplace in your home. We'll review the pros and cons below.

Pros:

• Because no heat escapes through a chimney, they have up to a 99% efficiency rating
• Ventless gas fireplaces can be installed in basements, newer homes and condos where chimney or venting is not an option 
• Aside from an optional annual checkup, which shouldn't cost more than $150, they require very little maintenance
• They can be installed both indoors and outdoors
• Ventless gas fireplaces don't produce any waste like ash or creosote
• Modern models come equipped with built-in oxygen and carbon monoxide sensors

Cons:

• Some people are sensitive to gas fumes
• Some  states and municipalities have banned the use of ventless gas fireplaces
• If your ventless fireplace uses propane, refills can be quite costly
• Because gas burns hot, they may not be suited for small  spaces

Can Ventless Gas Fireplaces Be Installed Outdoors?

Yes, ventless gas fireplaces can be installed outdoors! We offer several sturdy, weather-proof units that were crafted specifically for outdoor installation.

How to Choose the Right Ventless Gas Fireplace

Before you install a ventless gas fireplace in your home, you should ask yourself a few questions. 

• Where are you planning to install your new fireplace? In the living room? Outdoors? In your bedroom? Some states, such as North Carolina, strictly prohibit ventless gas fireplaces from being installed in smaller spaces such as bedrooms and bathrooms, so you'll need to review the laws in your area before deciding on a location.
• Do you want to be able to heat your entire home in the event of a power outage? Make sure that ignition comes with a battery ack up and look for recommended BTU guidelines per square feet to find out what you'll need to heat your home. 
• Are you installing your fireplace in a brand new construction, or are you renovating a prefab home? These factors can help you decide on the placement.
• Do you have enough space outdoors for a fireplace? If so, there are several attractive options. If not, don't give up yet. Some ventless gas fireplaces can be installed in a shared wall, half indoors and half outdoors. 
• What is the style of your home? Are you looking for something modern and visually lightweight? Or do you prefer more traditional designs with added visual weight from details like a mantel? Taking your overall style into account creates a more cohesive, aesthetically pleasing home. 
• How large is your space? Depending on the size of your rooms and your personal decorating style, a massive fireplace might not be your best option. Similarly, a slim, low-profile fireplace might not fit as well on a large wall. 
• Last, but certainly not least, what is your budget? Vented gas fireplaces are an affordable option, but some have higher price points than others. You can stick to your budget and still have the fireplace of your dreams.  

Thanks to their cost and energy efficiency, ventless gas fireplaces are an attractive addition to your home. Unlike traditional wood-burning fireplaces, which are inefficient for heating your home and produce waste and smoke, ventless gas fireplaces are a cleaner alternative for a much lower price.

Most modern units feature carbon monoxide and oxygen detectors that will switch off your fireplace if oxygen levels drop too low or carbon levels exceed the naturally occurring trace amounts in a room. Because they are required to meet federal guidelines before they can be sold, you can trust that ventless gas fireplaces are safe when they are used correctly.
