There are a few drawbacks to consider. The unit is designed specifically for natural gas, so if you're looking for a propane option, you would need to check compatibility or consider other models. Additionally, being a floor-standing unit, it may take up more space than wall-mounted options, which could be a concern in smaller rooms. While the safety features are commendable, the lack of advanced digital controls or smart technology may limit its usability for those who prefer modern features.
