Will the Dimplex flame operate without heat?

Yes! The Dimplex flame and heater operate independently of each other. This means you can enjoy the ambiance of a realistic flame all year round! In many gas units, the flame cycles off as the room temperature rises and you lose the flame effect until the room cools down again. In smaller rooms, gas fireplaces can be off a lot of the time and in the warmer climates they may not come on at all unless the thermostat is set higher than the room temperature.
