There are several different types of modern ventless outdoor fireplaces: outdoor electric fireplaces, ethanol fireplaces, and gel fireplaces. All these types are eco-friendly, smell and smoke-free, and don't require a chimney or a flue.
Outdoor Electric fireplaces run on electricity and present beautiful, realistic LED flames without any danger of fire. Safe for kids, pets, and people with asthma or allergies. They don't require any special installation permits and are usually recessed into a wall.
Outdoor ethanol or gel fireplaces use alcohol-based eco-friendly clean-burning ethanol or gel fuel and come in many different shapes and sizes. If you are looking for a unique design, modern ethanol fireplaces are your best bet to find it. Outdoor ethanol fireplaces can be mounted on the wall, set on the floor, table, or other leveled surface.
