Whoever said water and electricity don't mix never saw the Aqueon in action. The electrolysis-fueled fireplace passes an electrical current through water to separate the hydrogen from the oxygen. This ignites the hydrogen to produce a flame and releases the oxygen into the room. Because hydrogen combustion doesn't produce pollutants, the flame doesn't require venting. The Aqueon's fuel core fits into nearly any décor and can be placed wherever a proper electrical hookup exists. Heat & Glo, 888.427.3973
