FAQ's
View AllCan EcoSmart Fires be installed everywhere?
Almost everywhere! EcoSmart Fires cannot be installed into small rooms that are less than our minimum room size which is burner specific. For all other installations, you must comply with our compulsory clearances and installation instructions. Approval from building authorities may be required prior to installation in your area. Please make sure you contact appropriate parties before installing your EcoSmart Fire.
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.
What is the difference between gel and EcoSmart Fire’s ethanol fireplaces?
There are key differences between gel fireplaces and ethanol fireplaces in terms of operation and performance. Gel fireplaces are operated by inserting and lighting tin cans filled with gel. The cans act as the burner mechanism. Gel fireplaces do not produce a long coherent flame as known from ethanol fireplaces and can be difficult to extinguish. EcoSmart Fire’s ethanol fireplaces use a clean burning liquid fuel made with fermented plants. The fuel is housed in a ethanol burner that allows for safe and easy operation. Ethanol fireplaces produce a beautiful, vibrant dancing flame. Gel fuel should never be used within an ethanol fireplace.
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.
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
Why use an ethanol fireplace?
An ethanol fireplace is an eco-friendly and cost-effective alternative to gas fireplaces and wood burning fireplaces. Enjoy the warmth and aesthetic benefits of a traditional fireplace without the smoke, soot or ash in your home. 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.
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.
Can I extinguish my ethanol fireplace before the fuel has burnt?
Yes, you can turn your EcoSmart Fire ethanol burner off at any given time, even if there is ethanol still left in the burner. It is recommended however, that you leave it to burn until it completely runs out. The shut off mechanism is there for security and safety for those times when you need to leave the house, as it is not safe to leave a fire unattended. You need to wait until your appliance cools to room temperature (60 minutes) before re-igniting, this is because hot vapours are a hazard and may cause a strong, initial ignition if the ethanol has not cooled long enough. This is also to ensure that the flame has been totally extinguished and that the appliance is safe to refuel if the amount of fuel in the burner at that time is insufficient for your next ignition / use.
