Shop Gas Fireplaces by Type: Vented, Vent-Free & Inserts

Buying a gas fireplace isn’t about picking a flame you like and checking out.

The type of gas fireplace you choose determines everything:

• How safe it is in your home
• Whether it’s allowed by local building codes
• How much heat it actually delivers
• What installation will cost
• And how satisfied you’ll be long-term

This page exists for one reason: to help you buy the right gas fireplace type the first time.

Gas fireplaces fall into three main categories:

• Vented gas fireplaces
• Vent-free gas fireplaces
• Gas fireplace inserts

Each solves a different problem. Let’s break them down clearly so you can shop with confidence.

Vented Gas Fireplaces

The safest, most universally approved option

Vented gas fireplaces remove all combustion gases from your home through a chimney or direct-vent system.

They are designed for permanent installation and are approved in virtually all jurisdictions.

This category includes:

• Direct-vent gas fireplaces
• B-vent gas fireplaces
• Built-in vented gas units

Why Homeowners Choose Vented Gas Fireplaces

Vented systems are preferred when:

• Indoor air quality is a priority
• The fireplace will be used frequently
• Long-term safety matters more than maximum heat efficiency

Key advantages:

• Combustion gases are fully exhausted outdoors
• No oxygen depletion inside the room
• Stable, predictable flame behavior
• Approved for bedrooms and living spaces
• Strong resale appeal

What to Expect with Installation

Vented fireplaces require:

• A chimney or exterior wall access
• Professional installation
• Vent pipe routing (horizontal or vertical)

Installation costs are higher than vent-free units, but the trade-off is maximum safety and compliance.

Choose a Vented Gas Fireplace If:

• You want a long-term, permanent solution
• You’re building or remodeling
• You have children, elderly family members, or respiratory concerns
• You want the most code-friendly option

Vent-Free Gas Fireplaces

Maximum heat with minimal installation

Vent-free gas fireplaces operate without a chimney. All heat stays inside the room, making them one of the most efficient heating options available.

They are designed for supplemental heating, not whole-house heating.

Why Buyers Choose Vent-Free Gas Fireplaces

Vent-free fireplaces are popular because they deliver nearly 100% of heat into the room.

• Require no venting or chimney
• Cost less to install
• Produce strong radiant heat quickly
• Operate during power outages

They’re often used as:

• Zone heaters
• Supplemental heat sources
• Solutions for homes without venting access

Important Considerations Before Buying

Vent-free fireplaces:

• Use room air for combustion
• Release moisture and trace byproducts indoors
• Are regulated or restricted in some states and cities

You must verify local code approval before purchasing.

Choose a Vent-Free Gas Fireplace If:

• Your local building codes allow vent-free units
• You want strong heat without venting construction
• The fireplace will not be used continuously
• You want a lower upfront cost

Gas Fireplace Inserts

The smartest upgrade for existing fireplaces

Gas fireplace inserts are designed to fit inside an existing wood-burning fireplace opening. They turn inefficient open hearths into sealed, high-efficiency heating systems.

Why Inserts Are One of the Best Investments

Open fireplaces lose most of their heat up the chimney. Inserts solve this by:

• Sealing the firebox with glass
• Using a dedicated vent liner
• Actively circulating heat into the room

Benefits include:

• Dramatic efficiency improvement
• Cleaner operation
• Better heat control
• Modern appearance without demolition
• Lower energy waste

Installation Requirements

Gas inserts typically require:

• A compatible existing fireplace opening
• A stainless steel chimney liner
• Professional installation

While installation costs more than a vent-free unit, inserts often pay for themselves in efficiency gains.

Choose a Gas Fireplace Insert If:

• You already have a wood-burning fireplace
• Your current fireplace wastes heat
• You want modern convenience without rebuilding
• You plan to heat the room more efficiently

👉 Browse gas fireplace inserts sized to your existing opening.

Which Gas Fireplace Type Is Right for You?

Here’s a quick decision breakdown:

• No existing fireplace + highest safety → Vented gas fireplace
• No venting + strongest heat output → Vent-free gas fireplace
• Existing fireplace opening → Gas fireplace insert
