The Aqueon
The Aqueon doesn't just look cool, it is cool. It runs using tap water. The Aqueon works by passing an
electrical current through water to separate the hydrogen and oxygen, using the hydrogen to create the flame. The
fireplace puts oxygen back into the house and doesn't need to be vented. It stands about 60" tall and uses around
1/2 gallon of water per hour.
