Description
AUTHORIZED DEALER The Kozy Heat Osseo Insert Electric Fireplace is designed for one specific job: dropping into an existing fireplace cavity (wood-burning fireplace that’s no longer used, older gas unit being replaced, or new construction cavity sized for the Insert) and delivering modern flame ambiance plus modest supplemental heat without the complexity of gas line work or venting. Available in two sizes — Osseo e29 and e34 — the Insert Series turns an unused or outdated fireplace into a clean, customizable, plug-and-play feature in a single afternoon.
Why electric? Three big advantages over gas: No gas line required (plug into a standard 120V outlet, or hardwire), no venting required (no chimney work, no exterior wall vent), and dramatically simpler installation (typically a DIY afternoon project rather than a multi-day certified-installer job). The trade-off: electric fireplaces produce ambiance + supplemental heat, not primary heating. If you need real heat as a primary heating source, see our gas fireplace collection. If you want a fireplace that looks beautiful, runs anywhere there’s an outlet, and adds 5,000 BTU of supplemental warmth — the Osseo Insert Series is purpose-built for exactly that.

- Birch Log Set — lighter coloring with white-bark detailing, suits contemporary, Scandinavian, and minimalist styles
- Alternative Decorative Media — instead of logs, you can use:
- Driftwood — coastal/cottage aesthetic
- Small or Large Crystals — contemporary glass-bed look
- Lava Rock — modern volcanic-stone aesthetic
- River Rock — natural smooth-stone look
- Flame Color Options
- Traditional Orange — classic warm fire appearance
- Blue Flame — striking contemporary cool-tone look
- Orange + Blue Combination — blended dynamic effect
- 13 Glowing Ember Bed Colors — LED-illuminated ember bed colors that can be set independently from the flame, allowing extensive mood customization
- 7 Downlight Accent Colors — LED accent lighting that washes the firebox interior with selectable colors
- Chaska Decorative Screen Fronts — adds a decorative metalwork screen in front of the viewing glass for an additional layer of visual customization
