FAQ's
View AllAre 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.
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.
Do bioethanol fireplaces produce heat?
Yes, although it does depend upon the size of the fireplace and also the size of the room itself. But a fire of an appropriate size can produce a good level of heat when considered properly in terms of its actual output and how it is positioned in the space. Bioethanol fires are a secondary source of heat that deliver a myriad of lifestyle benefits that can’t be achieved from primary heat sources such as radiators or reverse cycle air conditioning.
Do ethanol fireplaces give off heat?
EcoSmart Fire’s indoor ethanol fireplaces are ventless, meaning all the heat stays in the room rather than escaping up a flue or chimney like it would with a traditional wood burning fireplace. Increased heat retention also means increased fuel efficiency. EcoSmart Fire’s collection of ethanol fireplaces offer a heat output ranging from 5,000 BTU - 20,000 BTU’s.
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 are the benefits of a zero clearance ethanol fireplace insert?
EcoSmart Fire’s Flex Fireplace Series has the necessary clearances to combustible frame components already built-in meaning they can be framed with wood studs. This gives you the freedom to install your ethanol fireplace insert in small and unique spaces. When selecting a location for the fireplace it is important to consider the required minimum room sizes and clearances. Please reference our Flex Series installation manual.
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.
