Dear Cleavin,
We appreciate your positive feedback and are glad to hear the product works perfectly for you.
To help extend the duration of your bioethanol burn, you might consider adjusting the burner opening using the sliding mechanism or closure plate—reducing the size can slow down the burn rate. Additionally, adding ceramic wool or fiber inside the burner can help absorb and distribute the fuel more evenly, resulting in a more stable and longer-lasting fire. If you need further assistance or tips, feel free to reach out!
