Buying Guide
- What space will you heat? Consider square footage and how well your room retains heat. Pellet inserts perform well in larger areas, while electric options suit medium rooms and apartments without venting.
- Fuel and maintenance: Wood inserts require regular cleaning and ash disposal. Pellet inserts need a steady fuel supply and hopper upkeep. Electric inserts need a power source and periodic filter cleaning.
- Install considerations: Zero-clearance designs simplify installation in existing masonry or framed walls. Check venting requirements, clearances to combustibles, and professional installation needs.
- Heat distribution: Look for fans or blowers that help distribute warmth. Larger inserts often include built-in blowers for better room circulation.
- Appearance and ambiance: Select a model with a realistic flame or glass front that matches your decor. Some options provide year-round flame visuals without heat.
