How does a ventless gel fireplace work?

A ventless gel fireplace operates by utilizing gel fuel canisters to create heat and a realistic-looking flame. The fireplace is designed with a burner unit that can be placed inside a safe enclosure, such as a decorative fireplace or a specially designed cabinet. Gel fuel, made from isopropyl alcohol, is poured into the burner unit and ignited using a long lighter or matchstick. The flames produced by the gel fuel create warmth and a cozy ambiance without the need for a chimney or venting system. The heat generated is purely radiant, meaning it directly warms the surrounding area. Ventless gel fireplaces are easy to use, as they require no gas lines or electricity, provide instant heat, and only produce minimal smoke and odors.
