Can I use an extension cord or power strip with an electric fireplace?
No — plug an electric fireplace directly into a wall outlet, never an extension cord or power strip. On heat it draws about 1,500 watts and 12.5 amps, right at a circuit's limit, and cords and strips aren't built for that sustained load — they overheat and become a fire hazard. Every manufacturer we carry prohibits it.
Why the manufacturers draw a hard line
An electric fireplace on high heat is a 1,500-watt appliance — the same class as a space heater. Extension cords and power strips are sized for lamps, chargers, and electronics, not a continuous 12.5-amp heating load. Push that current through undersized wire or a strip's internal contacts and the weak point heats up, the insulation degrades, and you've got a melt or a fire.
That's why the manual on every unit we carry — Dimplex included — says plug directly into a grounded wall outlet with nothing in between. Surge strips are no exception; their thin conductors and switch contacts are the exact failure point.
The real fix when the outlet's in the wrong spot
The usual reason people reach for a cord is a wall-mount or recessed fireplace going where there's no outlet behind it. The right answer isn't a cord snaking up the wall — it's an outlet where the unit lives.
When we plan an electric fireplace install, we position it so the cord reaches a proper receptacle, or we bring in a licensed electrician to add a receptacle in the wall cavity before the fireplace goes in. Adding or moving a circuit is electrical work, their trade — we coordinate it so the finished wall is clean, code-correct, and cord-free.
One honest reminder for WNC
Even wired perfectly, an electric fireplace is ambiance and light supplemental heat — up to roughly 400 square feet — and it goes dark the instant the power does. We saw what days without power looked like after Helene.
If backup heat is any part of why you want a fireplace, don't lean on electric; a gas unit with battery-backup or millivolt ignition, or a wood stove, is the heat that keeps working when the grid doesn't. Plug the electric in safely for the glow, and let fuel carry the cold nights. Call (828) 545-0525 and we'll help you plan both.
