I recently had a customer who wanted a fireplace in their bedroom separating their bedroom from their sitting room. As we discussed the options available for their fireplace they had a desire to minimize the size and space used by the fireplace, especially in the wall above the fireplace. They asked if there was an option that allowed for no flue or ventilation, but was still a gas fireplace with a real flame. I wasn’t aware of an option that would allow for a ventless fireplace. I decided to do some research to find out what was available and code restrictions surrounding their use.

Vented Vs. Ventless Fireplaces:

When it comes to adding a fireplace to your home, you have two options to choose from: vented and ventless fireplaces. Understanding the differences between these two types of fireplaces and the building code requirements for each is crucial in making an informed decision. In this article, we’ll explore the pros and cons of vented and ventless fireplaces, and provide you with all the information you need to choose the right one for your home.

Vented Fireplaces

Vented fireplaces are traditional fireplaces that require a chimney or flue to vent smoke and harmful gases outside the home. The chimney or flue acts as a pathway for smoke to escape, preventing the buildup of harmful gases inside the home. Vented fireplaces are known for their realistic flames and traditional look, making them a popular choice for homeowners.

Pros of Vented Fireplaces:

  1. Realistic Flames: Vented fireplaces offer the most realistic flame patterns and fire effects, making them a great choice for homeowners who want an authentic, traditional look for their fireplace.
  2. Better for the Environment: Vented fireplaces are better for the environment because the chimney or flue vents the release of harmful gases and smoke into the home.

Cons of Vented Fireplaces:

  1. Chimney or Flue Required: Vented fireplaces require a chimney or flue, which can be expensive to install and maintain.
  2. Lower Efficiency: Vented fireplaces are typically less efficient than ventless fireplaces, as they release a lot of heat through the chimney or flue.

Building Code Requirements for Vented Fireplaces:

Vented fireplaces must meet local building codes and regulations, including codes for chimney or flue construction and clearances. These codes ensure that the chimney or flue is safe and secure, and prevents the release of harmful gases into the home.

Ventless Fireplaces

Ventless fireplaces, also known as unvented fireplaces, do not require a chimney or flue. Instead, they use a closed combustion system that recycles the air in the room. This makes them a more convenient and cost-effective option for homeowners who want a fireplace but don’t want to pay for a chimney or flue.

Pros of Ventless Fireplaces:

  1. No Chimney or Flue Required: Ventless fireplaces do not require a chimney or flue, making them a more convenient and cost-effective option for homeowners.
  2. High Efficiency: Ventless fireplaces are highly efficient, as they do not release heat through a chimney or flue.

Cons of Ventless Fireplaces:

  1. Safety Concerns: Ventless fireplaces can produce harmful gases if not properly maintained and used, and pose a safety risk to homeowners.
  2. Building Code Restrictions: Ventless fireplaces may be restricted or prohibited in some areas due to local building codes and regulations.

Building Code Requirements for Ventless Fireplaces:

Ventless fireplaces must meet local building codes and regulations, including codes for proper installation and use. These codes ensure that the fireplace is safe and secure, and prevents the release of harmful gases into the home.

In conclusion, vented and ventless fireplaces each have their own pros and cons, and it’s important to consider these factors when choosing the right fireplace for your home. Whether you choose a vented or ventless fireplace, make sure to follow all local building codes and regulations to ensure the safety and efficiency
