Though water vapor fireplaces look realistic, you can actually reach out and touch the flames, as they are cold to the touch. However, Modern Blaze does offer water vapor fireplaces that come with a heat receptacle, to get the clean emission-free flame with the benefit of warmth, like the popular Dimplex Opti-Myst Pro 1000 Firebox.
All other water vapor fireplaces don't come with a heater, however, the heater can be purchased separately and added to Dimplex Opti Myst Pro Cassettes, Opti-Myst Pro 500 and Opti-Myst Pro 1000.
