Bio Ethanol Fireplaces Heat Output
What is the heat output that bio ethanol fireplaces produce? Find out right here in this article. We review the three different factors influencing the heat output, and give you a general idea of how much heat you can expect from an ethanol fireplace.
The heat output of bioethanol fireplaces is the result of three factors:
- The fireplace
- The quality of the bioethanol
- The size of the flames
If you don’t want to read all the details, you can skip right to the conclusion which is the last paragraph in the end of the article.
The ethanol fireplace & heat output
Let’s face it – there are many ethanol fireplaces out there, and their heat output vary between 1-7 kW depending on model. Some ethanol fireplaces come with a really (and sometimes too) long burner thus making the flames, and thereby heat output, very large. The fireplaces from Vauni on average produce 2.5 kW which is quite sufficient for any home. It is often the case that higher levels of heatoutput is a undesirable as it will get too hot in the room where the fire is located.
Other factors also weigh in with the different fireplaces. Some burners are produced in a way that results in the burner itself reaching high temperatures. This results in an extra amount of heat – but also consumption of fuel. Personally I don’t feel that the product has same control over the fire when the burner gets too hot. Other burners which are based on a ceramic core, keeps the burner and rest of the fuel at a safe temperature.
The quality of bioethanol & heat output
Besides the manifold of ethanol based fireplaces, we also find many different types of bioethanol. In general, bioethanol should have a clear liquid form and have a percentage of minimum 96%. The higher the percentage, the more flammable the fuel is – resulting in larger flames. This not only increases consumption of the fuel, but it also leads to a slight increase in heat output (although, there is not a significant difference).
The Size of the flames
A last factor is the size of the flames (not to confuse with the first point). Most of the safe and high quality ethanol fireplaces in the market has the option to regulate the flame size. It is simply done by sliding a lid over the opening in the burner from where the flames flow. By decreasing the opening with the lid, the flames will decrease in size resulting in a lower heat output.
So how big is the heat output from ethanol fireplaces?
After weighing in the different factors, I would say that most ethanol fireplaces produce between 2-4 kW heat output. There are some outliers which can produce up to 7 kW, and you should ask yourself whether this would be too much.
I always try to talk clients out of having super long flames (which most people want having seen gas fires) as they won’t be happy with the fire in the everyday use due to excessive heating. Another factor to remember is the running cost of running the fire can be significantly higher than other models, not to mention the time it takes to ignite the fire. Reaching nice and yellow flames with long burners can take op to 15 minutes.
