Ethanol fireplaces have carved out a niche for themselves in homes where a traditional chimney isn’t an option. They offer the ambiance of a live flame without the need for venting, and they’re relatively easy to install. But the fuel you choose matters more than you might expect. Roundfire Premium Ethanol Fuel, sold in a pack of three 1-liter bottles, is one of several options on the market. This review takes a closer look at what it offers, where it falls short, and who it’s actually for.
First, a bit of context. Ethanol fuel for fireplaces is typically sold as a liquid that’s poured into a burner can or tray. It’s available in different grades, and the purity of the ethanol affects how cleanly it burns. Roundfire markets its fuel as “premium,” which generally implies a higher ethanol concentration and fewer impurities. The product comes in three separate 1-liter bottles, which is convenient for storage and handling. Each bottle is resealable, so you can use what you need and keep the rest fresh.
In real-world use, this fuel is designed for ventless ethanol fireplaces, whether they’re freestanding units, wall-mounted models, or tabletop burners. It’s also suitable for some outdoor fire pits that are specifically made for ethanol. The 1-liter bottle size is manageable; you can pour directly into the burner without decanting into another container, though a funnel helps. The fuel ignites readily with a long lighter, and it burns with a visible flame that’s similar to what you’d get from other ethanol fuels. There’s no strong odor during combustion, which is a plus for indoor use.
One of the key functional features is the claimed purity. Roundfire states that its fuel is made from renewable resources and burns cleanly, producing primarily water vapor and carbon dioxide. In practice, any ethanol fuel will produce some odor when extinguished, and Roundfire is no exception. The smell is brief and not unpleasant, but it’s there. The burn time depends on the fireplace’s burner size and the amount of fuel used. A 1-liter bottle typically lasts several hours in a standard burner, but don’t expect it to last all evening if you’re running a larger unit.
Compared to generic ethanol fuels, Roundfire’s premium positioning might justify a slightly higher price for those who prioritize consistent quality. However, it’s worth noting that ethanol fuel is a commodity, and the differences between brands are often marginal. Some users might find that a cheaper, non-premium ethanol works just as well, especially in well-ventilated spaces. On the other hand, if you have a sensitive nose or are particularly concerned about indoor air quality, paying extra for a cleaner-burning fuel could be worthwhile.
One limitation is the packaging. While the 1-liter bottles are convenient, they’re made of plastic, which some environmentally conscious consumers may take issue with. Also, the bottles are not designed for long-term storage once opened; ethanol is hygroscopic, meaning it absorbs moisture from the air, which can affect burn quality over time. It’s best to use an opened bottle within a few months. Another trade-off is the cost per liter compared to buying ethanol in larger quantities. If you use your fireplace frequently, you might be better off purchasing a larger container to save money, though that comes with storage considerations.
In terms of performance, Roundfire burns consistently, with a steady flame and minimal soot. It doesn’t produce the popping and crackling of a wood fire, but that’s inherent to ethanol. The flame is clean and bright, and it doesn’t leave residue on the burner, which makes cleaning easier. However, like all ethanol fuels, it’s not a source of significant heat. It’s for ambiance, not warmth. Don’t expect it to replace a space heater.
Who is this for? It’s suitable for someone who uses an ethanol fireplace occasionally and values the convenience of smaller bottles. It’s also a good choice for those who want a fuel that’s labeled as premium and are willing to pay a bit more for perceived quality. It’s not ideal for heavy users who burn through fuel quickly, as the cost adds up. Nor is it for those on a tight budget who are comfortable with standard ethanol. And if you’re looking for a fuel that’s completely odorless, you’ll be disappointed—no ethanol fuel is entirely without some scent upon extinction.
Overall, Roundfire Premium Ethanol Fuel is a solid option that does what it promises. It burns cleanly, lights easily, and comes in a convenient size. The premium label may be more about marketing than a dramatically different product, but for many users, the consistency and peace of mind are worth the extra cost. Just be aware of the limitations: the plastic packaging, the need to use opened bottles relatively quickly, and the fact that it’s not a budget-friendly choice for frequent use.
