Gas Insert or New Fireplace? Choosing the Right Marquis for Your Home

October 20, 2026 · HeatSavers Team

If your home already has a fireplace, the first question we hear in the showroom is whether to convert it or start fresh. Both routes end with a clean, efficient gas fire, but they suit different homes, budgets and timelines.

When a gas insert makes sense

A gas insert slides into an existing masonry or factory-built firebox and vents up through the chimney with a flexible liner. You keep the surround and mantel you already have, and the work is usually done in a day. The Marquis Capella and Capri are built for this job.

• Your existing fireplace is structurally sound
• You like the current surround or mantel
• You want a quicker, less disruptive project

When a new fireplace is the better choice

A zero-clearance fireplace is framed into a wall and finished with whatever surround you like. It gives you a larger viewing area, more design freedom and the option to put fire in a room that never had one, from a classic Bentley to a long linear Infinite.

• There is no fireplace in the room yet
• You are renovating and want a modern, built-in look
• You want a wide linear or multi-sided view of the flame
