In general, it will take about 90 minutes to burn the creosote sweeping log by itself, allowing it to work its magic. This may be longer or shorter depending on the conditions of your chimney.

Modern gas fireplaces are relatively efficient and don't burn excessive amounts of gas, especially compared to older models. A gas fireplace might use between 10,000 to 40,000 BTUs per hour; the total amount of gas used depends on the fireplace's size, heat output, and how often it's in use. To help keep your running costs down, consider using a thermostat and turning off the fireplace when not needed to minimize gas consumption

A liter of bioethanol costs $11 and burns for around four hours, making it cost around $2.75 per hour to keep your bioethanol fireplace running. For comparison, natural gas costs around $0.50 per hour, and propane costs around $1.60 per hour. 

How much it costs you to run your bioethanol fireplace largely depends on how often you use it. Hypothetically speaking, if you run your fireplace for four hours a week year-round, you’ll go through one liter of biofuel per week or about $570 per year to run the fireplace.

The National Fire Protection Association (NFPA) says that chimneys and their associated elements like fireplaces, vents, or stoves should be cleaned at least once a year before the start of seasonal use. According to the Chimney Safety Institute of America, a chimney should be cleaned when there is 1/8 inch of soot buildup. If there’s more than that, creosote—a flammable byproduct of burning wood—can form and increase the risk of a chimney fire.
