The Designer's Guide to Specifying the Right Fireplace: Wood, Gas & Electric
Share
For interior designers and architects navigating the growing demand for statement hearth installations.
Why Fireplace Specification Matters More Than Ever
Fireplaces have moved well beyond functional heating. Today's clients expect a fireplace to anchor a room — a sculptural focal point that defines the entire design language of a space. As a designer or architect, your specification choice between wood-burning, gas, and electric will shape not just aesthetics, but structural requirements, permitting timelines, and long-term client satisfaction.
Here's what you need to know before you spec.
Wood-Burning Fireplaces: Authenticity & Atmosphere
Best for: Rustic, transitional, and high-end mountain or cabin projects where authenticity is non-negotiable.
Wood-burning fireplaces deliver an experience no other fuel type can replicate — the crackle, the scent, the organic flame behavior. For clients who want the real thing, nothing else compares.
Key specification considerations:
- Chimney & venting: Requires a full masonry or factory-built chimney system. Plan for vertical clearances and roof penetrations early in the design phase.
- Structural load: Masonry units add significant weight — coordinate with your structural engineer.
- Air supply: Modern builds require dedicated combustion air intakes to meet building codes.
Designer tip: Wood-burning inserts can retrofit existing masonry openings — a strong option for renovation projects where the client wants an upgrade without a full rebuild.
Top wood-burning pick: Invicta® Aaron 36" Double-Sided See-Through Cast Iron Wood Burning Stove — 99,000 BTU, made in France, and a perennial bestseller for open-plan and double-sided applications.
Gas Fireplaces: Precision, Convenience & Design Flexibility
Best for: Urban residences, high-rise condos, contemporary builds, and clients who prioritize ease of use.
Gas fireplaces are the workhorse of modern residential specification. They offer consistent flame output, remote or smart-home integration, and a wide range of linear and traditional formats that suit virtually any design direction.
Key specification considerations:
- Fuel source: Natural gas or propane — confirm availability at the project site before specifying.
- Venting options: Direct-vent (sealed combustion, most common), B-vent (open combustion), or vent-free (check local codes — not permitted in all jurisdictions).
- Linear vs. traditional: Linear gas fireplaces dominate contemporary and transitional projects; traditional box formats suit classic interiors.
Designer tip: Many gas units now support two-sided or see-through configurations — ideal for open-plan spaces where you want the fireplace to serve multiple rooms simultaneously.
Top gas picks:
- Malm Zircon Direct Vent Gas Fireplace — MCM Cone — A mid-century modern icon with a sealed direct-vent system. One of our top sellers.
- Malm Zircon B-Vent Gas Fireplace — NG or LP — Flexible fuel options in the same striking cone silhouette.
Electric Fireplaces: Maximum Flexibility, Zero Constraints
Best for: Apartments, rental properties, commercial hospitality spaces, and projects where venting is impossible.
Electric fireplaces have shed their reputation as a compromise option. Today's high-end electric units feature sophisticated flame simulation, adjustable color temperatures, and zero emissions — making them viable in spaces where gas and wood are simply not an option.
Key specification considerations:
- No venting required: Install virtually anywhere with a standard electrical connection. Ideal for interior walls, bedrooms, and upper-floor applications.
- Heat output: Electric units heat supplementally — they are not a primary heat source for large spaces.
- Smart integration: Most premium electric units support app control and integration with home automation systems.
Designer tip: Electric fireplaces are your fastest path from specification to installation — no gas line, no chimney, no permit delays in most jurisdictions.

Working With a Hearth Specialist
The best fireplace specifications happen early — ideally at schematic design, before framing begins. Engaging a hearth specialist at this stage ensures your chosen unit fits the structural, venting, and clearance requirements of the space without costly redesigns later.
At Smokey Mountain Fireplaces, we work directly with designers and architects on project specifications, providing CAD files, clearance documentation, and lead time estimates to keep your project on schedule.
