Frequently Asked Questions

1. What Is a B-Vent Fireplace?

A B-vent gas fireplace (also called "natural vent") works like a traditional fireplace but runs on gas. It pulls air from your room, burns gas, and vents exhaust up through your roof. You get realistic wood-fire flames without chopping wood or cleaning ash.

2. How Much Heat Will It Produce?

B-vent fireplaces heat 1,000-1,500 square feet effectively. Best for one room, not whole-house heating. You'll feel noticeable warmth in 15-20 minutes. Perfect for zone heating (warm just the rooms you use) and cutting heating bills.

3. Can I Install Without an Existing Chimney?

Yes, but you need to install a metal pipe through your roof. B-vents must vent vertically (straight up), not horizontally.

Costs:

  • With existing chimney: $1,500-$3,000 installed
  • Without chimney (new vent): Add $500-$1,500+

Get a professional inspection first—roof structure affects installation.
