There are several different types of modern ventless outdoor fireplaces: electric, ethanol, and gel. Electric fireplaces use electricity as a source of heat and flames. They present beautiful, realistic LED flame imitation. The heater is included with most fireplaces and is optional, meaning that you can enjoy beautiful flames with or without the heat - this feature is especially great for those who live in warm climates but still want to enjoy the ambiance an outdoor fireplace creates. Outdoor electric fireplaces are usually recessed into a wall and include a cover that protects them against the elements when not in use.
