Three-sided gas fireplaces create a visual statement that standard single-sided units simply cannot match. Heatilator, one of the longest-running names in the hearth industry, offers several peninsula and see-through models designed to be viewed from multiple angles. These fireplaces serve as architectural centerpieces while delivering real heat to your living space.
What Makes a Three-Sided Fireplace Different?
A three-sided fireplace, sometimes called a peninsula or bay-style unit, features glass on three faces. It projects out from a wall, allowing visibility from the left, right, and front. See-through models, by contrast, are installed within a wall and are viewable from two rooms. Both configurations turn the fireplace into more than a heat source. They become a design element that defines the flow of your floor plan.
Design Uses and Room Dividers
One of the most popular applications is using a three-sided fireplace as a room divider. In open-concept Las Vegas homes, a peninsula fireplace can separate the living room from the dining area without blocking sightlines. The flame is visible from both spaces, adding warmth and atmosphere to each room simultaneously.
Designers also use these units in master bedrooms, positioning them between the sleeping area and a sitting nook. In commercial settings like restaurants and hotel lobbies, three-sided fireplaces create focal points that draw guests in.
Multi-Room Heating
Beyond aesthetics, Heatilator three-sided models provide practical heating across multiple zones. Because the firebox is exposed on three sides, heat radiates in more directions than a traditional front-facing unit. This makes them effective for warming larger, open spaces. Direct vent technology ensures combustion air is drawn from outside, which keeps indoor air quality high and improves efficiency.
Heatilator Models to Consider
Heatilator offers several three-sided options at different price points. Key features to compare include:
- Viewing area dimensions, which determine how prominent the flame display will be in your room.
- BTU output, which should be matched to the size of the space you plan to heat.
- Ignition system type, including standing pilot and electronic ignition options.
- Interior finishing options such as reflective glass, matte black panels, or ceramic fiber logs.
Installation Considerations
Three-sided fireplaces require careful framing because the firebox extends into the room rather than sitting flush with a wall. A licensed installer should handle the gas connection, venting, and structural support. In Las Vegas, permits are typically required for new gas fireplace installations, and Hearth and Home Specialties can coordinate the entire process from selection to final inspection.
If you are building a new home or remodeling an existing one, a Heatilator three-sided gas fireplace is worth considering. Visit our showroom to see these units in person and discuss which model fits your space. Call us at (702) 474-4099 to schedule a consultation.
