| Supplemental heating | An electric heating element converts electrical energy into heat. Many units also use a fan to circulate warmed air. | Adds localized supplemental warmth. Heating performance and suitable room size depend on the unit, room conditions, and the manufacturer’s specifications. |
| Typical electrical demand | Many North American models offer a high setting around 1,500 watts. At that output, the heater uses about 1.5 kWh for each hour it runs continuously. | Actual energy use depends on the selected heat setting and how often the thermostat cycles the heater on and off. Check the product label and manual for the exact electrical requirements. |
| Flame effect | Lights—often LEDs—illuminate simulated logs or other materials. Depending on the design, moving light patterns or optical components create the appearance of flickering flames. | Enjoy a fireplace-like visual effect without a real fire, combustion, or chimney. Flame appearance and controls vary by model. |
| Flame-only operation | Many consoles let the visual flame effect run with the heater switched off. | Use the ambiance in warmer weather. The flame display still uses electricity; its exact consumption depends on the unit. |
| Separate heat and flame controls | On models with independent controls, the heater and flame display can be operated separately. | Choose heat, flame effects, or both, according to the controls included with the console. |
| Thermostat and heat settings | Many units provide adjustable temperature settings or more than one heat level. A thermostat can cycle the heater to help maintain its set temperature. | Controls can help manage comfort and runtime, but features differ. Consult the manual for the specific thermostat range and settings. |
| TV-console format | The fireplace insert is built into a piece of furniture designed to support or accommodate a television and provide storage. | Combines an entertainment center and electric fireplace in one footprint. Confirm the console’s dimensions, TV-support limits, and ventilation requirements before installation. |
| Installation and safety | Most electric inserts need an appropriate electrical outlet and clear airflow around their vents. They do not produce combustion exhaust. | Follow the unit’s clearance and electrical instructions. Keep vents unobstructed, and do not assume the console can share a circuit with other high-power appliances. |
