Ventless, or vent free, fireplaces are low-cost alternatives to traditional fireplaces with flues and chimneys. Many of these freestanding units are easy to install and more energy efficient than their traditional counterparts because heat is better contained and does not escape out the flue and up the chimney. While ventless fireplaces may heat more efficiently, the units require good ventilation. Baaroq ventless fireplaces are powered by natural fuel. Newer models may have a convenient automatic ignition feature, as well as an automatic thermostat to help control the heat output. #ventlessfireplace
