FAQ's

What is an ethanol fireplace insert?

EcoSmart Fire’s fireplace inserts are ready to install heating appliances that include single or multiple ethanol burners within a designed zero-clearance enclosure. Choose from over 219 single sided, double sided, bay, peninsula, island, and bench fireplace styles at multiple lengths. 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. Simply secure the ethanol fireplace insert in the framework, finish the surround, and it’s ready for use. EcoSmart Fire’s ethanol fireplace inserts can be installed virtually anywhere - in walls, cabinets, small spaces, high rise buildings, commercial spaces, indoors and outdoors.

How large of an area will my ethanol fireplace heat?

The heat output of our indoor and outdoor ethanol fireplaces vary based on the model selected. When used indoors, EcoSmart Fire’s ethanol fireplaces comfortably heat between 215 sq feet and 700 sq feet.

Do EcoSmart Fire ethanol fireplaces give off any fumes or gases?

Bioethanol fuel is made of fermented plants like sugarcane or corn and is essentially a liquid alcohol. To safely make “de-natured” and unfit for consumption, substances have been added. The burning of these substances may cause a slight smell upon initial lighting and when the flame is extinguished – similar to when you blow out a candle. Clean burning and eco-friendly, ethanol fuel releases heat, carbon dioxide (the same stuff we exhale) and steam.

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

How do I clean my EcoSmart Fire ethanol burner?

Cleaning of the ethanol burner should be done only after you have used 50 litres of fuel or as soon as you notice a black residue forming around or on the burner. Before starting, make sure the burner is off, empty of ethanol, and at room temperature. Spray a multi-purpose cleaner on the surface of the burner and wipe with cloth, making sure to wipe in the direction of the grain. If material has fallen into the ethanol fireplace burner use a vacuum cleaner to remove debris through the burner opening. If your burner smells unusually strong after extensive use, remove the empty and room temperature burner from its surround and wash in hot, soapy water. Rinse thoroughly under running water and wait until the burner is completely dry before placing it back into its surround and reusing. View this video of the simple cleaning process here: https://youtu.be/VqHg9mXOc0U

Note: Stainless steel will rust or corrode over time if contamination or debris is not cleaned or removed immediately. When not in use, we recommend that you protect your ethanol fireplace from water damage or corrosion with a protective cover and the regular use of the burner lid included with your model.

Where do I buy ethanol fuel for my ethanol fireplace?

e-NRG is the only bioethanol fuel recommended for your ethanol fireplace. e-NRG has been produced for the lowest odor, most vibrant flame, and longest burn time on the market. e-NRG has undergone rigorous third party testing with all EcoSmart Fire ethanol fireplaces. Use of any other fuel may damage your unit and void your warranty. You can purchase e-NRG ethanol fuel at e-nrg.com for fast and free shipping.

Are EcoSmart Fires easy to install?

EcoSmart Fires are designed to be easily installed and operated. Without the need for a flue or pipe connection, EcoSmart Fires are extremely flexible and can be incorporated at any stage of your interior decorating, renovating or building works. For detailed specifications please contact your local distributor.

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
