How long does ethanol fireplaces burn?
Its time to answer a question that I get all the time when giving potential customers advice on bioethanol fireplaces. Exactly how long does ethanol fireplaces burn?.
It is very difficult to answer the question with one definitive answer as many factors influence the burning time, listed according to importance, these factors include:
- The fireplace (size of flame and fuel tank)
- The fuel (some fuels are more flammable than others, which increases fuel consumption)
- Draught (exposing the flame to draught can increase fuel consumption as the flame gets bigger)
The Quick Answer: 4-6 Hours of Flames
In general an ethanol fireplace (excluding table top models) can burn between 4-6 hours regardless of size. The reason is that 4-6 hours is quite convenient, it is a bit more than most customers actually need. If it only burned 2 hours, it would cause problems in most cases.
A short note on tabletop fires
The models usually contain a small amount of fuel (0.5 liter) and can burn everything between 2-6 hours. As the burningtime and quality vary quite much, it is impractical to use these as an explanation of the burningtime.
Burningtime & Fuelconsumption
That being said, there is a difference between burningtime and fuel consumption. Some models burn 5-7 hours on 2 liters, where others with a larger flame require 4 liters to obtain the same burningtime.
For your convenience I’ve listed a number of models, their fuel capacity and minimum burningtime. Thereby you get a clear idea of how long bioethanol fireplaces burn.
- Globe – 2 liters – min 5 hours
- Divider – 3 liters – min 5 hours
- Cupola – 2 liters – min 5 hours
- Edge/Shadow – 2 liters – min 4 hours
- Gaya – 2.3 liters – min 6 hours
- Riviera – 2 liters – min 5 hours
- Curva – 2 liters – min 4 hours
- Carré – 2 liters – min 4 hours
- Zeta (BK5) – 5 liters – min 4 hours
- Fusion (BK2) – 2 liters – min 3 hours
- Citi (XS340) – 2.5 liters – min 4 hours
- Ghost (AB3) – 2.5 liters – min 6 hours
The fireplaces I have chosen are random, but still models that I would consider substitutes of a traditional woodburning stove. Thereby I can give you a more general response based on real numbers, and not guesstimates.
Total burning time (55) / Amount of fires (12) = Average minimum burning time 4.6 hours
My experience usually is that the Vauni products can obtain 8 hours of burningtime if you decrease the size of the flame. This generates lower heat, and decreases the fuel consumption – thus giving longer burning times. This applies for all models that comes with the possibility to regulate the flame size. Models like Ghost from EcoSmartFire and Gaya from Safretti does not have this option (to my knowledge), but the rest does.
Most models list a maximum burning time, but it really depends on the fuel. I would say that an average maximum burningtime for the same models would be around 6-7 hours.
