Fireplace & Hearth

Gas Fireplace

A gas fireplace delivers the warmth and visual appeal of a traditional hearth with the convenience of instant ignition, adjustable flame height, and zero ash cleanup. Fueled by natural gas or propane, these units range from realistic log sets that mimic a wood fire to contemporary linear burners with glass media and clean geometric frames. Gas fireplaces have become the most popular fireplace type in new construction thanks to their efficiency, ease of installation, and consistent heat output. Modern units achieve remarkably realistic flame patterns while meeting strict emissions standards, making them a practical choice for homeowners who want ambiance without the labor of hauling and splitting firewood.

Placement & Usage Tips

Direct-vent models offer the most flexibility in placement because they can vent horizontally through an exterior wall, eliminating the need for a vertical chimney. This allows installation on interior walls, below windows, or in rooms where a traditional chimney isn't feasible. For maximum design impact, consider a linear model set into a feature wall with floor-to-ceiling stone or tile. Position seating within 8 to 10 feet of the fireplace to create a cozy conversation area.

💡 Pro Tip

When choosing between direct-vent and ventless, consider that direct-vent units are safer for bedrooms and tightly sealed homes because they draw combustion air from outside. Ventless models deliver more heat to the room but add moisture and require adequate room volume. Always have a gas fireplace professionally installed and serviced annually—carbon monoxide detectors are a non-negotiable safety companion for any gas appliance.
