Get the size wrong and you pay twice. Buy a heater rated for 1,000 square feet for a 300-square-foot bedroom, and most of that heat leaves through the doorway while the furnace still runs all night.
The models below are the ones worth your money, chosen for room coverage, honest heat output and safety certification rather than flame colors alone. If you want the same comparison in a single ranked list with more units, start with for best electric fireplace heaters. The duraflame freestanding stove shows up most often in searches for electric fireplaces, and it earns attention with a glass door that actually opens and infrared heat for rooms up to 1,000 square feet.

Electric Fireplace Space Heaters: What Actually Sets Them Apart
Electric fireplaces mostly run on 1,000 to 1,500 watts, which translates to roughly 3,400 to 5,100 BTU of heat output. You get about 3.412 BTU per hour from each watt of resistance heat, so a 1,500 W unit delivers around 5,100 BTU/hr; a 1,400 W model hits close to 4,800 BTU, and a low 750 W setting yields about 2,560 BTU.
Room coverage claims depend heavily on how heat is delivered. Convection heaters (like models 2, 4, and 5) warm the air circulating in the room and are sized by floor area—good for evenly heating a small to medium room. Infrared models (products 1 and 3) focus warmth directly on people nearby, which feels immediate but doesn’t warm the whole space as much.
Most electric fireplaces let you run just the flame effect without heat, which many buyers appreciate for year-round ambiance. Every product here (1 through 5) offers flame-only mode. If you want ambience all spring and fall, that feature is often the main reason to pick one.
Controls vary more than you might expect and affect daily ease of use. Remote controls with timers (products 1 and 4) let you turn the heater off without getting up. Thermostat dials (products 2 and 3) allow easy temperature adjustment, especially with cold hands. Mechanical knobs (product 5) are simple but less precise.
Flame realism is mostly a finishing touch. All these fireplaces use LED-lit logs or crystals to simulate burning wood, so judge the flames by their color range and animation speed rather than vendor claims of “realistic” flames.
Quiet operation matters, especially in bedrooms. You won’t find noise ratings on specs sheets, but expect some fan noise when heating is on. Infrared models tend to be quieter since they don’t rely on fans as much. If you want whisper-quiet warmth, expect to pay attention to user reviews or test units in person.

Before buying an electric fireplace, take three key measurements: the width of your wall opening or free space, the height from finished floor to mantel or shelf above, and the depth from wall to front edge. Add a few inches clearance beyond the listed unit depth for air circulation.
Freestanding stoves (products 1, 2, 3, and 5) sit directly on the floor and need clearance around them. For example, the 23-inch ZAFRO stove measures 22.83″ wide by 11.02″ deep by 20.08″ high. The R.W.FLAME stands 17″ tall, and the OLIXIS is a compact 19″ unit at 14″ wide by 7.8″ deep by 18.9″ high.
| Model | Width (in) | Depth (in) | Height (in) | Heat Settings (W) |
|---|---|---|---|---|
| R.W.FLAME | 17 | varies | varies | 750/1500 |
| ZAFRO | 22.83 | 11.02 | 20.08 | 1000/1500 |
| duraflame freestanding | varies | varies | varies | varies |
| OLIXIS | 14 | 7.8 | 18.9 | varies |
| 60-inch insert | 60 | varies | varies | 1400 |
Built-in fireplace inserts like the 60-inch model (product 4) require a framed opening in the wall and a clearance to combustibles. The manufacturer specifies these minimum clearances and the unit draws about 1,400 W, covering up to 400 square feet. Keep those clearance numbers handy during installation.
If you want a 20-inch electric log set with heater, your best bets are the 19-inch OLIXIS and the 17-inch R.W.FLAME. Both combine glowing logs behind glass with a working heat mode, but no exact 20-inch log set with heat is widely available.
Mantels and surrounds affect heat clearance. MDF or painted wood mantels are common and fine if you follow the minimum clearance to combustibles the unit requires. Keep clearances visible during installation to avoid heat damage.
For low-profile shelf or media console installations, consider smaller electric fireplace space heaters detailed in our guide to small fireplace space heaters.
What an Electric Fireplace Costs to Run in January
Electric fireplaces use electricity, typically between 500 and 1,500 watts, to produce heat and simulate flames. The power requirement depends on the model and heat setting, with 1,500 watts being common for maximum heat output.
To calculate heat output, you can convert watts to BTUs using the rule that 1 watt equals about 3.41 BTU per hour. For example, a 1,500-watt heater delivers roughly 5,100 BTU per hour.
Running a 1,500-watt heater for 8 hours uses 12 kilowatt-hours (kWh) of electricity (1,500 W ÷ 1,000 × 8). At 17 cents per kWh, that adds up to approximately $2.04 per night. A 1,400-watt insert consumes 11.2 kWh in the same period, costing about $1.90. Smaller 750-watt or 500-watt settings cut usage and costs accordingly.
| Heater | Watts | Per hour | Per day (8 h) | Per month (30 days) |
|---|---|---|---|---|
| 1,500 W heater | 1,500 W | 26¢ | $2.04 | $61.20 |
| 1,400 W insert | 1,400 W | 24¢ | $1.90 | $57.12 |
| 750 W low setting | 750 W | 13¢ | $1.02 | $30.60 |
| 500 W flame-only mode | 500 W | 8.5¢ | 68¢ | $20.40 |
Zone heating pays off if you lower your central thermostat by three to four degrees and heat only the room you’re in. Otherwise, heating just one space while the rest of the house remains cold won’t save much energy.
The flame-only mode uses about 500 watts for visual effect with minimal heat. Running this feature costs little and is why many keep their electric fireplace plugged in year-round.
Large built-in units like the 60-inch model should ideally be on their own dedicated circuit to prevent overload.
Safety, Certification and the Clearance You Cannot Skip
Certified electric fireplaces carry ETL, UL, or CSA marks showing they meet safety standards for tip-over, overheating, and temperature limits. If you don’t see a certification mark on the product, it’s best to avoid it.
You can surround most electric fireplaces with drywall or sheetrock safely, but the wall’s framing and clearances must follow the manufacturer’s instructions exactly. Drywall itself isn’t combustible, but improper clearance or framing can create fire risks.
Clearances come in two kinds: the fire-safety minimum distance to combustibles like walls and furniture, and the recommended operational clearance around air outlets. Freestanding stoves commonly require 3 to 4 inches clearance on sides and rear just for safety.
Overheat cutoffs on models like Products 1, 2, and 5 protect against fire hazards. Avoid stacking magazines or blankets near or on top of the heater, especially over air outlet vents usually found at the top.
Keep electric fireplaces out of children’s reach, never place them on shelves above head height, and avoid use in bathrooms or damp areas. Make sure pets or kids can’t tip a freestanding unit onto soft materials like blankets.
Retiring a Gas Fireplace for an Electric Insert
Replacing a gas fireplace with an electric insert is straightforward when the gas unit no longer works. The existing flue, damper, and masonry stay in place behind the finished wall. Since electric inserts don’t burn fuel, they need no venting or chimney connection.
If your gas fireplace still works, you can’t just swap it out yourself. A licensed plumber must shut off and cap the gas line, and most places require a permit to keep it legal. Ignoring that risks leaks and code violations.
Measure the existing opening before buying an insert. Electric inserts come in set sizes, so you size the surround and finish to the unit, not the other way around. The 60-inch electric fireplace offers a built-in style with two flame displays, while freestanding stoves suit odd or small openings better.
Electrical needs vary by model. Most 120 V inserts plug into a standard wall outlet. Hardwired 240 V units demand an electrician and a permit. Confirm the unit’s power requirements before framing your wall or building the surround.
Building an accent wall around your insert means following the unit’s listed clearances and temperature ratings for mantel materials. Use heat-rated MDF or other approved surfaces to avoid damage or fire risk. Keep the required gap between the unit and any combustible finish.
When the Flames Work but the Heat Doesn’t
If your electric fireplace shows flames but no heat, start with the easiest fixes. Check that it’s not set to flame-only mode, the thermostat isn’t set below room temperature, and the power switch on the unit is on, not just the remote responding.
| Code | Meaning | What To Do |
|---|---|---|
| E3 | Over-temperature fault; heater overheated and shut off | Unplug unit, wait 30 minutes to cool, clear airflow obstructions |
| E5 | Temperature sensor or thermistor fault | Call a technician for sensor repair; not resettable |
| EE | Control or communication fault between main board and display | Unplug and replug; if persists, professional service needed |
The E3 error is the most frequent and means the heater shut down after overheating. It usually clears if you unplug the unit and let the elements and fan cool for half an hour. Make sure nothing blocks the vents or fan before restarting.
An E5 error points to a problem with the temperature sensor circuit—either a faulty thermistor or a loose connection. This isn’t something you can reset; a service call is in order. If your own thermometer shows the unit is hot but the code persists, trust the sensor fault.
EE errors signal a communication glitch between the control board and the display or remote. Power cycling may clear it, but persistent problems require replacing or repairing the control board or wiring.
Remote controls often use symbols to show mode: a flame icon means flame-only, a heater icon means heat mode, and a snowflake or fan icon means the fan is running. If the remote doesn’t respond, replace the batteries with fresh ones, making sure polarity is correct.
For deep cleaning or repainting, unplug the fireplace, remove the front glass and logs, and vacuum inside gently. Paint only the cool, external surfaces—never the glass, heating elements, or vents. Opening the unit means photographing cable routes and expecting the glass and logs to lift out without tools. Avoid wiring or element repairs unless you’re qualified.
