How Many Amps Does an Electric Fireplace Use?

Electric Fireplace amperage at 120 V and 240 V

Same 1,400 W load: the current halves when the voltage doubles. Electric Fireplace is typically a 120 V appliance in US homes.

Breaker and circuit for an electric fireplace

At 12 A, an electric fireplace fits comfortably on a standard 15 A or 20 A household circuit. For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations), sized at 125% of the running current because it runs 3+ hours at a time (NEC 210.20).

Guidance only: actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.

Measure what an electric fireplace actually draws

The figures above are typical ratings. A plug-in power meter between the outlet and the cord shows the real amps and watts with nothing opened up. A clamp meter reads one conductor at a time, so it is the tool for hardwired and 240 V circuits; clamped around a whole cord it reads close to zero.
