The Science Behind Ethanol Fireplaces

What is Bioethanol Fuel?

Bioethanol Fuel

Bioethanol fuel is a type of ethyl alcohol made from fermented agricultural products like corn, sugarcane, and wheat. As a form of renewable energy, it produces fewer emissions compared to fossil fuels such as coal, petroleum, and natural gas.

The only byproducts are water vapor and minimal amounts of carbon dioxide. You can see a sample of bioethanol fuel in the picture above, and it’s available for purchase along with ethanol fireplaces at US Fireplace Store.

How is it used in the Fireplace?

In a standard ethanol fireplace, there is a burner reservoir where the fuel is poured. This fuel is then ignited with a long lighter or match. Depending on your fireplace model, you can adjust the flame using a remote control, slider, or lid to meet your needs.

      Ethanol fireplaces are known for their efficiency in fuel and heat handling, as well as ease of installation and maintenance.

      Since bioethanol fuel burns cleanly, it produces minimal byproducts. Nearly 97% of the fuel’s energy is converted into heat, with very little soot, ash, or smoke. This makes ethanol fireplaces very consumer-friendly, as they do not require major home renovations like adding a chimney or venting system. Additionally, they need fewer maintenance checks due to the lack of emissions.

      In contrast, wood-burning fireplaces have an efficiency rate of 10-30%, with a lot of heat lost through the chimney. Gas fireplaces offer a better balance between efficiency and convenience, with an efficiency rate of 70-90%.

      Heating Capabilities

      Before discussing heating capabilities, keep in mind that ethanol fireplaces are mainly designed for decorative and supplementary heating. They should not replace your primary heating source.

      The heating capabilities of a bio-ethanol fireplace depend on its design, operation, and purpose. On average, a manual ethanol fireplace generates between 2,000 and 9,000 watts of heat. Automatic models, which have features for easier refueling and flame adjustment, can produce between 2,000 and 15,000 watts of heat. High-end models can even output up to 50,000 watts, suitable for large spaces.

      The heating power of these fireplaces can also be measured in BTUs per hour, with various models ranging from 1,400 to 50,000 BTU/hr.

      Below is a table that shows different types of bio-fireplaces along with their estimated heat output in watts and BTU/hr:


      Heat Output in Watts (W)



      2,900 - 9,000

      10,000 - 30,000


      2,900 - 15,000

      10,000 - 50,000


      1,400 - 9,000

      5,000 - 30,000


      2,300 - 9,000

      8,000 - 30,000

      What are BTUs?

      British Thermal Units (BTUs) is a measure of heat that indicates the energy required to heat or cool one pound (roughly 0.45 kilograms) of water. To calculate how many BTUs you need to warm up your room, simply multiply the square foot area of your space by 20 BTUs.

      Area Coverage

      Bio-fireplaces can be used both indoors and outdoors, but they are best for heating smaller areas.

      The size of the area a bio-fireplace can heat depends on the model and capacity of the fireplace. Factors like room size, layout, ambient heat, and insulation also affect how well the fireplace distributes heat.

      Always follow your manufacturer’s recommendations for minimum room size, usually starting at around 400 square feet, to ensure adequate heat dissipation and personal safety.

      Below is a table that shows the approximate size of the area that different fireplaces can cover:


      Area of Coverage (sq. ft.)


      500 - 1,500


      500 - 2,500


      250 - 1,500


      400 - 1,500


      The cost of bioethanol is approximately $60.51 for 20 liters, with bulk purchases reducing the price by $7.44 per 20 liters.

      How much do you exactly need to use?

      The amount of fuel you need depends on your fireplace model, usage frequency, and flame size. Typically, a small burner uses about 1 to 1.3 liters of fuel to burn for up to 6 hours.

      Below is a table that shows each type of fireplace, how many liters you need, its burning time, and its running cost:


      Fuel Needed in Liters (L)

      Burning Time in Hours (h)

      Cost per hour in USD ($)


      1 - 1.3 L

      3 - 6 h

      $0.99 - $1.80


      1.5 - 3 L

      3 - 5 h

      $1.24 - $2.48


      2 - 4 L

      4 - 7  h

      $1.61 - $3.10


      1.5 - 3 L

      3 - 5 h

      $1.24 - $2.47
