FAQ's
View AllWhere is the best place to install an ethanol fireplace?
Our ethanol fireplaces can be installed virtually anywhere - in walls, cabinets, high rise buildings, commercial / residential / hospitality spaces, indoors and outdoors. Because EcoSmart Fire’s ethanol fireplaces are ventless, they require no gas line, no electricity, and no chimney for a hassle free and cost effective installation. Our ethanol fireplaces have been designed and tested with safety as our top priority. We have outlined requirements for each ethanol burner, ethanol fireplace insert, and ethanol freestanding fireplace in our collection. These guidelines include minimum room size requirements and clearance recommendations for flammable materials and movable objects. Please refer to our manual for more information.
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

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.
What is a bioethanol fireplace?
A Bioethanol fireplace is an open fireplace that is fueled by bioethanol. A real flame is produced by the lighting of bioethanol, with a by-product being heat in the process. It is a fireplace that needs no flue for exhausting emissions, no utilities such as electricity or gas connection, and it uses a sustainable fuel source.
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.
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.
Can I extinguish my ethanol fireplace before the fuel has burnt?
Yes, you can turn your EcoSmart Fire ethanol burner off at any given time, even if there is ethanol still left in the burner. It is recommended however, that you leave it to burn until it completely runs out. The shut off mechanism is there for security and safety for those times when you need to leave the house, as it is not safe to leave a fire unattended. You need to wait until your appliance cools to room temperature (60 minutes) before re-igniting, this is because hot vapours are a hazard and may cause a strong, initial ignition if the ethanol has not cooled long enough. This is also to ensure that the flame has been totally extinguished and that the appliance is safe to refuel if the amount of fuel in the burner at that time is insufficient for your next ignition / use.
