Fuego Flame prides itself on offering one of the most fuel efficient and high heat producing fireplaces on the market. The key to a Fuego’s efficiency lies in the adjustable damper and fireplace design that provides the proper air-flow without the use of noisy and expensive blowers. Air flow is controlled to provide ultimate burning conditions. The Fuego engineers designed the fireplace for optimum operation without the use of electricity. The Fuego Flame’s natural convection blower circulates heat up to 250 cfm - the highest heat output on the market with or with a blower.
