Are Electric Fireplaces Safe? Fire Risks, Clearances and the Features That Matter
Electric fireplaces appeal for one reason. They give the look of a fire with no chimney, smoke or gas line. There is a catch, though. The flame is only light. The heater behind it is a real resistance heater that can draw around 1,500 watts, and it can start a fire if it is crowded, plugged in wrong or defective.
So, are electric fireplaces safe? This article answers that with maker manuals, CPSC recalls and federal fire data. It also looks at what is worth powering when the grid goes down.
The Short Answer: Safe When Installed and Plugged In the Way the Maker Says
An electric fireplace has no open flame, no combustion and no flue. That removes the chimney fires and gas risks tied to other fireplaces. What remains is an electric heater with hot parts inside.
Are electric fireplaces safe for everyday use? Generally, yes. Most of the safety story comes down to how the heater is placed, powered and maintained.
Can electric fireplaces cause fires?
Yes, and the heater is the usual source. Three sources show how.
A federal recall: The CPSC recalled about 14,670 Twin-Star infrared quartz electric fireplaces sold at Lowe's (recall 24-023, Nov. 9, 2023). The agency said the units can overheat, posing a fire hazard. It cited 24 reports of overheating, fire or smoke, including two cases of property damage and no injuries.
A maker warning: The Dimplex manual states that "All electrical heaters have hot and arcing or sparking parts inside." Those parts are normal. They are also why space and care matter.
Federal fire data: A 2021 USFA report on heating fires found heating was the second leading cause of residential building fires, after cooking. For portable heaters from 2017 to 2019, USFA data lists a heat source too close to things that burn as the leading factor, at 48%. USFA does not break out electric fireplaces, so this is portable heater data, not electric fireplace data.
Electric fireplaces don't burn fuel, so they avoid the carbon monoxide risks that come with gas generators and fuel-burning heaters. Since the heater is where the risk lives, placement is the first thing to get right.
Placement, Clearance and Outlet Rules From the Makers
Clearance rules differ by model, and makers do not all publish the same distances. Federal guidance sets a baseline. The manual sets the rest. Here is what the sources say.
Rule | Source | What it says |
Combustibles in front | Touchstone Sideline Elite manual (rev. 2025-03-12) | Keep combustible materials at least 36 inches from the front and 8 inches from the top to a mantel |
Anything that can burn | Keep anything that can burn at least 3 feet from heat sources, including fireplaces | |
Air intake and front | Dimplex DF series manual | Do not partly or fully cover the front, and keep intake slots clear |
Wall outlet only | Dimplex Essence and DF manuals | Plug directly into a wall outlet, never an extension cord or relocatable power tap (power strip) |
No surge protector | Touchstone Sideline Elite manual | Never plug into a surge protector, extension cord or relocatable power tap |
Circuit | Dimplex Essence manual | 120V, 12.5A, 1,500W, with a dedicated, properly fused 15A circuit recommended |
Wet rooms | Dimplex manuals | Not for use in bathrooms, laundry areas or similar indoor locations |
Dimplex's manuals list only rear and underside clearance, at least 1/2 inch behind the unit. They give no front distance. That is why reading the manual for the exact model matters.
Hardwired units need extra care. Touchstone says a qualified electrician must remove the cord connection if the unit is hardwired.
Wall-mounted and insert models
Recessed and wall-mounted units add mounting and wiring questions. Follow the installation section of the manual. Use a licensed electrician for any hardwired or new-circuit work. Because these units sit inside walls or cabinets, spacing and circuit details are easy to get wrong.
Some owners assume a surge protector makes a fireplace safer. Yet the power strip vs surge protector difference does not matter here, since Touchstone's manual rules out both.
Placement covers the owner's part. The fireplace's built-in features cover the rest. When the power goes out, those features do not all need the same amount of energy.
Flame Effect vs Real Heat: What's Worth Powering in an Outage
The glowing flame and the heater are two separate loads. On Dimplex models, they "operate independently." The flame uses slightly under 300 watts, while flame plus heater pulls about 1,500 watts. That gap decides what backup power can sensibly run.
Flame-only mode varies: Not every fireplace has one. The Touchstone Sideline Elite manual lists a heater-off setting (H0) and says the flame stays on until the unit is powered off. The heater needs the flame on, but the flame does not need the heater. Check the model’s controls and nameplate first.
The heater is resistance heat: Dimplex rates it at roughly 5,115 BTU at 1,500 watts. That takes the chill off a room. It is not whole-house heat.
Some units should stay unplugged: Never power a fireplace that has tripped its overheat cutout repeatedly, has a damaged cord or is under recall.
Once the owner knows which mode the fireplace offers and what its label says, the backup can match the job.
For flame-only ambiance on models that allow it, the load is small. A flame display and a lamp draw far less than a heater, so a compact battery fits.
Heater mode is a different job. A 120V plug-in heater needs a unit whose output covers both the rated and startup demand, plus enough stored energy to run for a few hours.
How the two products divide the job
The EcoFlow DELTA 3 Classic suits low-power tasks. That means the flame display and lighting, but only on fireplaces whose maker lets the flame run apart from the heater.
The EcoFlow DELTA 3 Ultra Plus suits the heater mode of a 120V plug-in fireplace. Both the rated and startup demand must fit within the unit's output. It provides limited hours of warmth.
Neither power station raises the fireplace's safety rating. Plug the fireplace directly into the power station, as makers require for wall outlets. Never power a faulty unit. Do not expect overnight or whole-home heat.
Runtime estimates (labeled examples)
The planning formula is simple: capacity (Wh) x 0.85 for conversion losses, divided by load (W).
Example | Load used | Estimate |
EcoFlow DELTA 3 Classic, flame effect only | Just under 300W (Dimplex FAQ), so 300W is used | 1,024 x 0.85 = 870Wh; 870 / 300 = about 2.9 hours |
EcoFlow DELTA 3 Ultra Plus, flame plus heater at full draw | 1,500W (Dimplex Essence nameplate) | 3,072 x 0.85 = 2,611Wh; 2,611 / 1,500 = about 1.7 hours |
EcoFlow DELTA 3 Ultra Plus, heater cycling about half the time | About 750W average (Dimplex's own cost example assumes 50% cycling) | 2,611 / 750 = about 3.5 hours (example only) |
Actual time depends on the thermostat setting, how cold the room is and what else is plugged in. Dimplex says its flame uses slightly under 300 watts, but its Essence and DF manuals do not list LED flame wattage. Owners should check their own label.
Before sizing backup for heat, it helps to see how heater and power station compatibility works for running watts and runtime. Back in everyday use, the built-in safety features are worth understanding, because they work only when the fireplace is set up right.
Electric Fireplace Safety Features, Explained
Most electric fireplaces include an overheat cutout, and many add timers and thermostats. These features reduce risk, but they do not replace clearance and correct wiring. Here is what each one does, based on makers' own descriptions.
Overheat cutout: Dimplex says an automatic cutout turns the heater off if it overheats. It stays off until reset by unplugging for 5 minutes. Touchstone describes a similar automatic shutoff at an unsafe temperature.
Sleep timer: Dimplex manuals describe a built-in sleep timer. It helps limit run time if the heater is left on by mistake.
Certification: Dimplex Essence says it is "certified to meet UL Standards." Touchstone says its unit was tested to CSA Standards. USFA advises choosing a heater tested by a recognized testing laboratory.
Tip-over switch: USFA recommends heaters with automatic shutoff if they tip over. Wall and built-in fireplaces may not have one, so it should not be assumed.
A fireplace heater's 1,500 watts makes a modest amount of heat, and converting watts to BTU shows why it cannot replace a furnace. Features help. Daily habits do most of the work.
Electric Fireplace Safety Tips for Every Day
A good routine takes a minute and covers most of the risks in recall reports and fire data. Pin this list near the fireplace for the first winter. Then it becomes a habit.
Keep a 3-foot zone: Anything that can burn should stay at least 3 feet away, per USFA. Use more distance if the manual says so.
Plug into the wall: Skip extension cords, power strips and surge protectors. Dimplex and Touchstone both require a direct wall outlet.
Give it its own circuit: Do not plug other appliances into the same circuit. Touchstone says this, and USFA says the same for space heaters.
Turn the heater off when leaving or sleeping: This is USFA's advice for portable heaters, so it applies most to heater mode.
Supervise children: Dimplex and Touchstone both call for close supervision around the unit.
Retire damaged cords: Dimplex says not to run the unit with a damaged cord or plug. USFA says to replace cracked cords, not repair them.
Check for recalls: Search the model on CPSC.gov and stop using it if it is listed.
Test smoke alarms: USFA found alarms were present in only 41% of portable heater fires in occupied homes. Working alarms are cheap backup.
These habits fit into a broader winter storm outage plan that also covers food, water and staying warm without heat.
Conclusion
So, are electric fireplaces safe? Mostly, when the maker's rules are followed. Electric fireplaces avoid combustion risks, but their 1,500W-class heaters can still overheat if crowded, plugged into a power strip or defective, as recent recalls show.
The fix is simple. Follow the manual's clearance and wall-outlet rules, check recalls, and turn the heater off when leaving or sleeping.
For outages, the EcoFlow DELTA 3 Classic suits flame-only ambiance on compatible models. The EcoFlow DELTA 3 Ultra Plus can run a plug-in heater mode for a few hours.
FAQs
Can an electric fireplace start a fire?
Yes. The heater can overheat, as in a 2023 CPSC recall of about 14,670 units. Federal data also shows that placing portable heaters too close to things that burn is the leading factor in their fires, at 48%. Clearance matters.
Are electric fireplace heaters safe to leave on overnight?
Follow the manual first. Federal guidance for heaters is to turn them off when leaving the room or going to bed. Heater mode falls under that advice, so it should not run while everyone sleeps. Check whether flame-only use is allowed.
Can I plug an electric fireplace into a power strip?
No. Dimplex and Touchstone both say to plug directly into a wall outlet. Neither allows an extension cord or power strip, because the heater draws about 1,500 watts and can overload them. A surge protector is ruled out too.
Does an electric fireplace work without heat?
Many do. Dimplex says its flame and heater work independently. Touchstone's Sideline Elite also allows the flame effect to stay on with the heater set to H0 (off). Check your model's controls and manual for its flame-only settings.
How much power does an electric fireplace use?
About 1,500 watts with the heater on, per Dimplex. Dimplex says its flame alone uses slightly under 300 watts, so flame-only use draws far less than heater mode. The nameplate on each unit lists its own rating, which should guide backup sizing.
