Enjoy an alluring flame from any angle you look at it.

Specifically designed for a single room application, the Flex Single Sided Fireplace Insert features one open side, enabling the flame to be viewed from the front.

FAQ's

View All

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.

Are ethanol fireplace inserts difficult to install?

Unlike gas fireplaces or traditional wood burning fireplaces, our ethanol fireplace inserts require no venting, no gas line, no electricity - eliminating the need and cost of three sub contractors. They are simply mounted into the constructed main wall framework with the appropriate opening size for the fireplace insert selected. EcoSmart Fire’s ethanol fireplace inserts are extremely flexible and can be incorporated at any stage of your interior decorating, renovating or building works. For detailed specifications please contact us.

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 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

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 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.

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.

How long does it take to assemble?

There is virtually no assembly. Our Freestanding and Fireplace Grates ranges are designed to be placed into the desired location, secured into position, and operated immediately. Our Fireplace Inserts are designed to slot into place, secured and built around with your preferred finish – again a quick and easy installation – so your builder or interior designer will love you!

The longest part of the setup process is trying to figure out where you want to place it – be sure it complies with our clearance requirements particularly with regard to moving objects like curtains, tree branches and so forth.
