Clean-Burning Ethanol Fireplace, a Luxury Upgrade for Any Indoor or Outdoor Space

Redecorating your home can be a time-consuming, expensive, and exhausting affair. You’re stuck with the same interior from years ago and you need to make a statement that suits the modern world.

Adding a fireplace to an indoor or outdoor space is a great way to inject life back into your home or outdoor area, but vented fireplaces are expensive and costly to maintain.

Discover the EcoSmart Fire Flex Single-Sided Ethanol Firebox; an eco-friendly unvented fireplace with clean, smokeless flames that will have everyone talking! Not only does it offer an easier and more practical installation, but its minimalistic design will complement any room.

Although this ethanol fireplace produces less heat than gas fireplaces, it doesn't require gas lines or electricity; nor does it require chimneys or vents! Its steady-burning orange ethanol fire is lit with liquid bioethanol, a more sustainable source of fuel. With no expensive renovations required, just have it recessed into a wall, pour some fuel, light it up, and enjoy beautiful real flames without any smoke, fumes, or mess.

Great for any home, big or small, 9 sizes are available, from 15" to 159" viewing areas! Take out all the mess and fuss from enjoying the warmth and ambiance of a real flame in your home. Shop now and take advantage of our free shipping offer.
