How Does a Water Vapor Fireplace Work?
Water vapor fireplace runs on water and electricity. It uses tap water to emit fine mist into the air. The light of LED lights gets reflected by this mist creating a realistic 3-dimensional illusion of flame and smoke.
Water Vapor Flame
The newest technology manages to create an extremely realistic flame look without the presence of a real fire. Flame imitation is so realistic, you’ll be surprised to learn you can actually touch this “fire.”
Realistic cool-to-the-touch flame is created by energy-efficient LED lights and water vapor. These cold mist artificial fire fireplaces run on electricity and regular tap water. All you need to do is plug them into a standard household outlet (or hardwire), add water (or connect to a water line) to the tank and enjoy!

Do Water Vapor Fireplaces Give Off Heat?
Though water vapor fireplaces look realistic, you can actually reach out and touch the flames, as they are cold to the touch.
Most water vapor fireplaces do not come with a built-in heater.
