In-Wall Bioethanol Fires Unlike gas and electrical fires that require an external connection to utilities, bioethanol fires run solely on fuel. This makes them a lot simpler and more affordable to install than their equivalents. Ethanol fireplaces don't require a chimney or flue, and they can be moved from room to room as your spatial requirements change.
