FAQ's

What is bioethanol fuel?

Bioethanol (also known as methylated spirits or simply ethanol) is a form of renewable energy. It’s a clear, colourless liquid that’s commonly made from fermenting the sugar and starch components of plant by-products like sugarcane and grain crops.

Is their heat output similar to a gas heater?

Burning bioethanol is similar to gas, but the room doesn't dry out like it does with gas - a more gentle, softer heat is created. Heat-wise, it depends on the models being compared. Some of our bioethanol burners output 15,000 BTU and can heat up to 60sqm of living space. Bioethanol is not, however, on an adjustable thermostat. Some may be turned up and down, but you can't control the room temperature in the same way as you do with gas on mains

How does an ethanol fireplace work?

EcoSmart Fire’s ethanol fireplaces are self-contained, burning bioethanol fuel that is housed within the stainless steel container. A flame regulator controls and stabilizes the flame. With a designated filling area, and easy shut off mechanism, you can ignite the flame and turn it off in a matter of seconds. View this quick demonstration video to help illustrate the process.

What is the difference between gel and EcoSmart Fire’s ethanol fireplaces?

There are key differences between gel fireplaces and ethanol fireplaces in terms of operation and performance. Gel fireplaces are operated by inserting and lighting tin cans filled with gel. The cans act as the burner mechanism. Gel fireplaces do not produce a long coherent flame as known from ethanol fireplaces and can be difficult to extinguish. EcoSmart Fire’s ethanol fireplaces use a clean burning liquid fuel made with fermented plants. The fuel is housed in a ethanol burner that allows for safe and easy operation. Ethanol fireplaces produce a beautiful, vibrant dancing flame. Gel fuel should never be used within an ethanol fireplace.

Why use an ethanol fireplace?

An ethanol fireplace is an eco-friendly and cost-effective alternative to gas fireplaces and wood burning fireplaces. Enjoy the warmth and aesthetic benefits of a traditional fireplace without the smoke, soot or ash in your home. Unlike gas fireplaces or traditional wood burning fireplaces, EcoSmart Fire’s ethanol fireplace inserts require no venting, no gas line, no electricity - eliminating the need and cost of three sub contractors.

Are ethanol fireplaces good for the environment?

EcoSmart Fire’s ethanol fireplace burners and fireplace inserts, when paired with our e-NRG bioethanol fuel are clean burning with the only byproduct being heat, steam and carbon dioxide (the same stuff we exhale). Unlike gas fireplace inserts and wood burning fireplace inserts, EcoSmart Fire’s ethanol fireplaces do not produce messy pollutants like soot, smoke, and ash.

How to install a TV or AV equipment above an ethanol fireplace?

This design can be achieved as long as the TV is protected. You have 3 possible solutions:

Solution 1: The TV needs a non-combustible mantel/ledge to act as a heat shield

Solution 2: The TV needs to be recessed in a niche

Solution 3: The TV needs to sit back off the level of the flame

How to position your TV

What are some key benefits – compared to other heating options?

When you choose ethanol as your fuel source over gas or wood, you are totally simplifying your installation requirements and costs. There's no flue or chimney required when burning ethanol, which means that you have the ultimate in design flexibility to achieve an open fire in so many more areas of your home - both indoors and out.
