What are the electrical requirements for an electric fireplace?

Depending on the model, electric fireplaces will operate on either 120 volts or 240 volts or electricity.  Most common is 120 volts and they plug into a standard wall outlet.  Although some codes may not require it, most dealers and electricians will recommend installing a designated circuit from your electrical distribution panel.  A 240 volt requirement will definitely need a separate line from your circuit breaker panel.  Always check local codes and the owner’s manual for your specific model.
