FAQ's

View All

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.

What maintenance is required for ethanol fireplaces?

Clean your EcoSmart Fire unit after you have used 50 liters [13.20 Gal.] of fuel or as soon as you notice black deposits on or near the burner of the ethanol fireplace. Black marks can be removed from the stone, solid surfaces or stainless steel with a mild abrasive washing product such as JIF or similar. It is recommended to test a small area first to ensure the cleaning product chosen is appropriate and will not mark or damage the surface. Burners can be washed as required in hot soapy water (even in your dishwasher) from time to time and the internal mechanics won’t deteriorate like some other brands as all internal parts are stainless steel.

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.

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.

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.

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.

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.
