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.
Do ethanol fireplaces smell?
All heating appliances have their own smell be it gas, wood or electric - ethanol fireplaces are no different. e-NRG ethanol 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. e-NRG ethanol fuel is the only fuel recommended for your EcoSmart Fire ethanol fireplace. e-NRG ethanol fuel has the lowest odor and longest burn time on the market. The nice thing about using ethanol is that it’s not dry like gas or smokey like wood.
What are the benefits of using a bioethanol heater compared to heating your house with a reverse cycle air conditioner?
It’s important to understand the difference between “foundation” heating and occasional heating. Quite often these are two completely different yet complementary systems that work hand in hand. Reverse cycle air conditioning doesn't give you a beautiful flame and lifestyle benefits of an EcoSmart Fire. However, By combining reverse-cycle air conditioning and an EcoSmart Fire within your home you can have the ‘best of both worlds’ - effective heat and ambiance.
How do I fill my ethanol fireplace?
With EcoSmart Fire’s proprietary tools and procedures, filling your ethanol fireplace with e-NRG bioethanol fuel is fast and easy.
Step 1: Remove the bottle nozzle cap and carefully insert into the filling point
Step 2: Push and hold the green button. The nozzle will automatically stop filling once the reservoir is full.
Step 3: Replace the nozzle cap.
You can view a step-by-step filling video.
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.
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

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.
