Adding a Fireplace to an Existing Home
A complete guide to retrofitting a fireplace into your current living space. Learn about the best options, installation requirements, and how to choose the right type for your home.
Start Your ProjectRetrofit Made Simple: Adding a fireplace to an existing home is more achievable than ever. Modern ventless and electric options eliminate the need for a traditional chimney, making it possible to install a beautiful fireplace in almost any room.
Why Add a Fireplace to Your Existing Home?
Adding a fireplace is one of the most impactful home improvements you can make. It creates a natural focal point, adds warmth and ambiance, and can increase your home's appeal. For many homeowners, the desire to add a fireplace stems from a wish to create a cozy gathering space or to add a touch of luxury to a living room or bedroom.
Before you begin, it's helpful to understand the fireplace buying guide and the types of fireplaces available. The right choice for a new construction home is often different from the best option for a retrofit. In an existing home, you'll need to consider factors like available space, venting options, and whether you have access to a gas line.
Best Fireplace Types for a Retrofit
When you are adding a fireplace to an existing home, not all types are created equal. Some require major construction, while others are designed specifically for easy installation. Here are the most practical options:
Electric Fireplaces
The most flexible option for a retrofit. They require no venting, no gas line, and often no major structural changes. You can plug them in and enjoy them immediately. Many models, like a fireplace insert, are designed to fit into an existing firebox.
- Installation: Simple, often DIY-friendly
- Venting: None required
- Best for: Apartments, bedrooms, and rooms without a chimney
Ventless Gas Fireplaces
These models burn gas and vent directly into the room, eliminating the need for a chimney or flue. They are highly efficient and provide real flames. However, they require a gas line and proper ventilation. A ventless natural gas heater is a great example of this technology.
- Installation: Requires a gas line, no chimney
- Venting: Ventless (direct vent into room)
- Best for: Homes with gas access but no existing chimney
Direct Vent Gas Fireplaces
A direct vent model uses a sealed combustion chamber and a horizontal vent kit that goes directly through an exterior wall. This makes it a great choice for homes without a chimney. Installing a direct vent gas fireplace is a common retrofit project.
- Installation: Requires a gas line and wall venting
- Venting: Direct vent through wall
- Best for: Homes where a wall vent is possible
Wood Burning Inserts
If you already have an old, inefficient masonry fireplace, a wood burning fireplace insert can transform it into a powerful heater. This is a great way to upgrade an existing feature without a full rebuild.
- Installation: Requires a professional and a chimney liner
- Venting: Uses existing chimney (with new liner)
- Best for: Upgrading an existing masonry fireplace
Comparing Retrofit Options at a Glance
| Fireplace Type | Venting Requirement | Installation Complexity | Best For |
|---|---|---|---|
| Electric | None | Low (DIY-friendly) | Any room, apartments, quick upgrades |
| Ventless Gas | None (vents into room) | Moderate (requires gas line) | Rooms with gas access, no chimney |
| Direct Vent Gas | Horizontal wall vent | Moderate to High | Homes where exterior wall venting is possible |
| Wood Insert | Chimney liner required | High (professional install) | Upgrading an existing masonry fireplace |
Key Considerations Before You Install
Before you commit to a project, it's important to plan carefully. Here are the most critical factors to evaluate:
Venting & Chimney
Do you have an existing chimney? If not, you'll need to choose a ventless or direct vent model. Understanding if you need a chimney or vent is the first step. A DIY ventless fireplace is a popular choice for this reason.
Gas Line Access
If you want a gas fireplace, you'll need a gas line. If you don't have one, you'll need to hire a professional to install it. This is a significant factor in the overall fireplace cost breakdown.
Electrical Requirements
Electric fireplaces need a power source. Some models can be plugged into a standard outlet, while higher-output models may require a dedicated circuit. Always check the installation requirements.
Space and Sizing
Measure your space carefully. You'll want to choose a fireplace that is proportional to the room. Use a fireplace sizing guide to determine the right BTU output for your square footage.
The Installation Process: What to Expect
The installation process varies greatly depending on the type of fireplace you choose. For an electric model, you might be able to complete the project in a single afternoon. For a gas or wood-burning unit, you will almost certainly need to hire a professional.
If you're considering a DIY approach, read our guide on DIY vs professional fireplace installation. For gas and wood installations, it's crucial to work with a certified technician to ensure safety and compliance with local codes. You will also likely need a fireplace permit.
