New Gas Fireplace Installation (Vented vs. Ventless)

If you’re considering a new gas fireplace, one of the first decisions you’ll need to make is choosing between a direct vent fireplace and a ventless fireplace.

Vented Fireplaces

Traditional vented fireplaces are fueled by natural gas or propane, utilizing vent pipes or flue to operate safely. They are an exceptional alternative to a wood-burning fireplace, offering the beautiful aesthetics of a roaring fire. Many homeowners add a vented fireplace to complement their home’s interior rather than use it as a primary heat source. The heat from its logs escapes through the vents, requiring more time and gas to heat larger rooms.

Ventless Fireplaces

Ventless fireplaces are popular because they burn at nearly 100% efficiency, according to the International Association of Certified Home Inspectors. They work by drawing air for combustion directly from your room and heating that air. Since they don’t require ventilation, the majority of the heat stays in your home.

Many modern systems are thoroughly inspected and tested to national standards. Some models also come with built-in oxygen depletion sensors to regulate the amount of oxygen present. When it gets too low, the fireplace automatically shuts off. 

Ventless fireplace installations are quite straightforward, and you can place them throughout your home.

Gas Fireplace Installation FAQs



Yes, gas fireplaces have greater energy efficiency than wood-burning fireplaces. Heat tends to escape through the chimney of a traditional wood-burning fireplace, whereas gas fireplaces are designed to retain the majority of the heat they generate inside the home.

A gas insert is a complete system that inserts into your existing fireplace for whole-room heating, and gas logs are realistic-looking logs that provide supplemental heat output. A gas insert is the best option if you want efficient heating, while gas logs are better if you want a more decorative fireplace.

The pros of a direct vent gas fireplace are:

  • Enhanced safety due to fumes and byproducts venting directly outdoors
  • Beautiful, realistic flames that resemble a traditional wood-burning fireplace
  • Flexible installation that allows you to install it in various locations

A direct vent fireplace can also present cons such as:

  • Higher installation costs
  • Lower efficiency

You can enjoy the following pros of a ventless gas fireplace:

  • Strong supplemental heat output for greater warmth
  • High efficiency
  • Lower installation costs

A ventless gas fireplace can also present the following cons:

  • Potential for moisture buildup
  • A greater need for adequate ventilation in the home
  • Less realistic flames

Ventless gas fireplaces are safe when you install and maintain them properly. However, they can present some safety concerns because they release combustion byproducts into the home. You can take the following precautions to enjoy your ventless gas fireplaces safely:

  • Trust a professional to install your fireplace
  • Schedule regular gas fireplace maintenance
  • Install carbon monoxide detectors throughout your home
  • Use them as supplemental heat sources, not your main heat source
  • Ensure adequate room ventilation

Each ventless gas fireplace is equipped with an oxygen depletion sensor that automatically turns the fireplace off if oxygen levels lower too much.

No, you do not need an existing chimney or fireplace to install a gas fireplace. Many gas fireplaces can be installed without venting or through an exterior wall.
