Yes, many electric fireplaces support 240V wiring, delivering up to 10,000 BTUs of heat—double the output of standard 120V models. These high-voltage units are ideal for heating larger spaces (up to 800–1,000 sq. ft.) and often require hardwiring by a licensed electrician. Options include built-in, linear, and insert models with dual-voltage compatibility for flexible installation.
Key Takeaways
- 240V fireplaces generate 8,500–10,000 BTUs vs. 5,000 BTUs for 120V models.
- Heat areas up to 800–1,000 sq. ft., perfect for open-concept rooms.
- Most 240V units must be hardwired to a dedicated circuit for safety.
- Some models switch between 120V (plug-in) and 240V (hardwired).
- 240V units draw ~2,500–2,700 watts but heat more efficiently per watt than 120V.
120V vs. 240V: What’s the Difference?
- 120V Fireplaces: Standard household outlets; max 1,500 watts (~5,000 BTUs). Best for small rooms (400–500 sq. ft.).
- 240V Fireplaces: Heavy-duty circuits; max 2,500–2,700 watts (~10,000 BTUs). Ideal for large spaces (800–1,000 sq. ft.).
Pro Tip: 240V wiring is common for appliances like dryers or ovens. If your home already has a 240V outlet, installation may be simpler.
Types of 240V Electric Fireplaces
- Built-In: Recessed into walls for a seamless look; requires professional hardwiring.
- Linear: Modern, wide designs (33″–100″) with high heat output; popular in open living areas.
- Inserts: Fit into existing fireplaces; some offer dual-voltage options.
- Freestanding Stoves: Mimic wood stoves but with 240V power for whole-room heating.
Installation & Electrical Requirements
1. Dedicated Circuits: Why They Matter
A 240V fireplace must be on a dedicated circuit to prevent overloads. Test your circuit by turning off the breaker—if other outlets/lights turn off, it’s not dedicated.
2. Hardwiring vs. Plug-In
- Hardwired: Required for most 240V models; involves direct wiring to the electrical panel.
- Plug-In: Rare for 240V; if included, the cord must be removed before hardwiring.
Safety Note: Always hire a licensed electrician for 240V installations to meet local codes.

Final Thoughts
240V electric fireplaces are a game-changer for homeowners needing robust, efficient heat. While installation is more involved, the payoff—warmer rooms, lower energy waste, and sleek designs—makes them a top upgrade. Always consult an electrician and check product specs to ensure compatibility with your home’s wiring.
FAQs
Can I convert a 120V fireplace to 240V?
No—unless the manufacturer explicitly states dual-voltage compatibility. Most units are designed for one voltage only19.
Do 240V fireplaces cost more to run?
Not necessarily. While they draw more power, their higher efficiency means faster heating and lower long-term costs for large spaces.
Are 240V models safer than 120V?
Both are safe, but 240V units often include advanced safety features like auto shut-off and thermal overload protection.
Can I install a 240V fireplace myself?
Hardwiring requires an electrician to ensure compliance with building codes and prevent fire risks19.
