Do I need to service my ethanol fireplace in any way?
Yes, normal maintenance and care is very important! Instructions are included in the Installation, Operating and Maintenance Manual supplied with your EcoSmart Fire product.
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.
Do bioethanol fireplaces produce heat?
Yes, although it does depend upon the size of the fireplace and also the size of the room itself. But a fire of an appropriate size can produce a good level of heat when considered properly in terms of its actual output and how it is positioned in the space. Bioethanol fires are a secondary source of heat that deliver a myriad of lifestyle benefits that can’t be achieved from primary heat sources such as radiators or reverse cycle air conditioning.
How long will my ethanol fireplace burn?
Burn times for our ethanol fireplaces vay based on flame size and fuel capacity of the burner. EcoSmart Fire’s ethanol fireplaces will burn between 8-13 hours when full.
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

Why use bioethanol?
Bioethanol, a renewable energy, is the cleanest and most efficient fuel on the market, which means there are no emissions and no soot or ash to clean up.
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.
