Best electric fireplace heater: every plug-in unit is a 1,500 W space heater behind glass, so the maker manuals sort them by circuit, size, flame-only mode and the one 240 V exception
Maker manuals compared: Touchstone Sideline 28, 12 A plug-in only; PuraFlame Western 750/1500 W, 4600 BTU; Dimplex IgniteXL 2,500 W, 8,530 BTU on 240 V, UL file.

Short answer
For a wall-recessed unit on an ordinary outlet the pick is the Touchstone Sideline 28: its Sideline manual prints 120 V AC, Max 1500 W, 12 A, a 15 A grounded outlet, no extension cord, a 28 x 16.5 x 5.5 in body and a 1-year warranty, and it cannot be hardwired. For an existing opening the pick is the PuraFlame Western insert, whose manual prints 750/1500 W, 4600 BTU maximum, 12.5 A, 400 sq ft maximum, a remote and a thermostat. Neither makes more heat than a space heater: EIA prints 1 kilowatthour as 3,412 Btu, so every 1,500 W fireplace delivers about 5,118 BTU/h. The one exception is the Dimplex IgniteXL XLF74, whose sell sheet prints 2,500 W and 8,530 BTU on a hardwired 240 V supply and whose installation guide prints UL Listing File Number E71416. Skip every unit here if the room needs more than one space heater’s worth of heat and the budget stops at a plug.
The picks
Has a dead masonry fireplace and wants the cheapest glowing log set
Duraflame electric log set, 400 sq ft heater (for an existing fireplace)
Amazon's listing prints no model number; Duraflame's DFI020ARU log-set manual, the closest document opened, prints 120 VAC 60 Hz, 11.7 A and 1400 W with no BTU and no lab mark, so this listing's own figures are not confirmed from a maker document
Wants a wall-recessed unit on an ordinary outlet and no electrician
Touchstone Sideline 28 (80028) recessed electric fireplace
Touchstone Sideline manual: 120 V AC, Max 1500 W, 12 A, 28 x 16.5 x 5.5 in, 22 lb, 15 A grounded outlet, cannot be hardwired, no extension cord, 1-year warranty; product page: 1,300 W, 3,750 BTU, 300 sq ft, flames with no heat, remote, WiFi app
Has a cabinet or fireplace opening 32.3 to 34.3 in wide to fill
PuraFlame Western electric fireplace insert, 33 1/16 in wide (EF45D size)
PuraFlame Western manual: 120 V, 750/1500 W, 4600 BTU max, 12.5 A, 400 sq ft max, remote and thermostat, 120 V 15 A circuit, EF45D opening 32.3-34.3 in wide by 25.6-26.6 in high, 1-year limited warranty; no lab mark in the manual text
Wants more than 1,500 W of heat and will pay an electrician for 240 V
Dimplex IgniteXL 74 in linear electric fireplace (XLF74)
Dimplex sell sheet: 120 V / 1,500 W / 5,118 BTU or 240 V / 2,500 W / 8,530 BTU, 120 V plug-in cord kit or hardwire, warms up to 1,000 sq ft, 5 yr warranty; installation guide: UL Listing File Number E71416, dedicated 15 A circuit recommended, no extension cord, 1 year outdoor / 5 year indoor
If you are buying an electric fireplace because the furnace cannot keep the room warm, close this page and read the space heater review instead: the heater inside every plug-in fireplace below is the same 1,500 W element at several times the price.
How was this shortlist built?
Every figure here is a manufacturer-published specification read on 2026-10-09 from the manual, sell sheet or product page named beside it; nothing was installed, run or measured by this site, and every listing was confirmed in stock the same day. Units were compared on heater watts, printed BTU, supply voltage and amps, plug-in versus hardwire, form and opening size, flame-without-heat mode, printed lab listing, remote and thermostat, and warranty years.
A lab listing is named only where the document prints it. Of every manual opened, only the Dimplex IgniteXL guide prints one, a UL file number, so no other row claims a mark.
Three gaps are stated, not filled. Duraflame’s Amazon listing prints no model number and its own manual could not be matched, so its row carries the DFI020ARU sibling’s figures. Dimplex’s Multi-Fire XHD inserts are not buyable on Amazon today, so the XHD is in the table and not in the picks. Napoleon, Amerihome, R.W.Flame and Southern Enterprises published no spec document that could be opened, so they are absent.
How do the units compare on paper?
| Unit | Heater | BTU (maker) | Supply | Form and size | Flame without heat | Listing printed | Remote / thermostat | Warranty |
|---|---|---|---|---|---|---|---|---|
| Duraflame log set (DFI020ARU manual) | 1400 W, 11.7 A | Not printed | 120 V plug-in | Log set for an existing fireplace | Not printed | None printed | Remote (listing title) | Not printed on the page read |

| Dimplex IgniteXL XLF74 | 1,500 W at 120 V or 2,500 W at 240 V | 5,118 / 8,530 | 120 V cord kit or hardwire 120 V (3-wire) / 240 V (4-wire) | Linear, 74-1/4 in wide, 1,000 sq ft (sell sheet) | Not printed in the documents read | UL Listing File Number E71416 | Remote (sell sheet) | 5 yr indoor, 1 yr outdoor |
Where a product page and the manual disagree, both figures are printed with their source: Touchstone’s Sideline 28 page says 1,300 W and the Sideline manual’s table says Max 1500 W.
Why is a plug-in electric fireplace only a 1,500 W heater?
Because a 120 V outlet caps it. ESFI’s booklet says a 15 A circuit at 120 V carries 1,800 W and recommends not exceeding 80 percent, 1,440 W. A 1,500 W element draws 12.5 A, the figure Lasko’s support page prints for its space heaters on high, and the figure PuraFlame and Dimplex print for their inserts. The arithmetic is worked through in the breaker-tripping guide.
EIA prints 1 kilowatthour as 3,412 Btu, so 1,500 W is about 5,118 BTU/h, the pair Dimplex prints for the IgniteXL on 120 V. Whether that element sits in a ceramic tower, an oil-filled radiator or behind a flame screen changes nothing about the heat; the oil-filled versus ceramic guide covers what it does change.
The running cost is the same too: the space heater running cost calculator takes the wattage on the fireplace’s label and returns the cost per hour, day and month.
Duraflame electric log set: buy it or skip it?
Buy it if a masonry fireplace sits dark and you want a glowing log set with a remote at the lowest price on this page. The flaw is the paperwork: Amazon’s listing prints no model number, and the closest Duraflame document opened, the DFI020ARU log-set manual, prints 120 VAC 60 Hz, 11.7 A and 1400 W with no BTU and no lab mark.
Skip it if a maker-printed figure for the exact unit matters: this page cannot confirm the listing’s own wattage, square footage or listing mark from a Duraflame document.
Touchstone Sideline 28: buy it or skip it?
Buy it if you want a recessed wall unit that plugs into an outlet you already have. The Sideline manual prints 120 V AC, Max 1500 W, 12 A, a 28 x 16.5 x 5.5 in body at 22 lb, a 110 V 15 A grounded outlet with no other appliances on the circuit and a 1-year warranty; the product page adds flames with no heat, a remote, a WiFi app and a thermostat with overheat shut-off.
The flaw is the wattage: the page says 1,300 W and 3,750 BTU for 300 sq ft, the manual’s table says Max 1500 W, and the manual prints no ETL or UL text. The Sideline 28 cannot be hardwired, so the cord has to reach an outlet.
Skip it if you want the hardwire option: Touchstone prints plug or hardwire only for the Fireplug Pro series, and no Amazon listing could be matched to that document.
PuraFlame Western insert: buy it or skip it?
Buy it if you have a cabinet or an old fireplace opening to fill and want a thermostat. The Western manual prints 120 V, 750/1500 W, 4600 BTU maximum, 12.5 A, 400 sq ft maximum, a remote and a 1-year limited warranty, and its opening table gives the EF45D 32.3 to 34.3 in wide by 25.6 to 26.6 in high. The listing’s 33 1/16 in width matches the 33.05 in dimension the manual prints for the EF45D.
The flaw is the cord rule, which the manual prints twice and differently: the safety list says never use an extension cord or relocatable power tap, and the installation section allows a grounded 14 AWG cord rated at least 1875 W and no longer than 7.87 ft. The manual prints no lab mark.
Skip it if the opening is outside the table: the EF42D, EF43D and EF44D are the same insert at 21.9-23.9, 25.2-27.2 and 29.1-31.1 in wide, and the Amazon family lists them as variants.
Dimplex IgniteXL 74: buy it or skip it?
Buy it if the room genuinely needs more than one space heater and you will pay an electrician. The XLF74 sell sheet prints 1,500 W and 5,118 BTU on 120 V or 2,500 W and 8,530 BTU on 240 V, a 120 V plug-in cord kit or hardwire to either voltage, a 74-1/4 in wide body that recesses into 2 x 6 framing and a 5 yr warranty; the installation guide prints UL Listing File Number E71416, a recommended dedicated 15 A circuit and 1 year outdoor, 5 year indoor.
The flaw is that the extra heat exists only on the 4-wire 240 V supply the guide describes, which is new wiring and a permit in most homes; on the plug-in cord kit it is a 1,500 W heater like the rest.
Skip it if the point is the flame: at this price the 240 V heat is what you are paying for.
Check the circuit before you buy
Do not order any unit until you know which breaker the outlet is on and what else is on it. ESFI’s booklet puts a 15 A circuit at 1,800 W with a recommended 1,440 W ceiling, and every manual here specifies a 15 A circuit with nothing else plugged in. If the only outlet shares a circuit with a television or a hair dryer, the fix is a different outlet or the low setting, and the breaker guide shows the arithmetic. Buying in a sale window changes none of it: the space heater deal check covers what Black Friday and Prime Day actually move.
Who should skip an electric fireplace?
Anyone buying it for heat. A plug-in unit delivers about 5,118 BTU/h at most on EIA’s conversion, the same as a space heater, at the same running cost.
Anyone without a spare circuit. Dimplex’s guide requires a dedicated circuit if the breaker trips after installation, and the Touchstone and PuraFlame manuals forbid other appliances on the line.
Anyone who needs the 240 V heat but will not hardwire. The 2,500 W figure appears on no plug-in unit here.
What goes wrong?
It is on an extension cord. CPSC says to plug electric space heaters directly into a wall outlet and never into an extension cord or power strip; ESFI says the same and adds not to plug anything else into the heater’s outlet. Four of the five manuals here agree outright, and PuraFlame’s allows only a short 14 AWG cord.
The breaker trips. At 12.5 A a 1,500 W element is already over ESFI’s 12 A guideline for a 15 A circuit; a television on the same line tips it. Dimplex’s answer is a dedicated circuit, not a larger breaker.
It stands too close to what burns. CPSC says to keep portable heaters at least three feet from drapes, furniture or bedding, and the PuraFlame manual says not to place the heater near a bed. An electric fireplace burns nothing, but the house around it still needs working alarms: the smoke detector review and the CO detector review cover the ceiling.
Frequently asked questions
How much heat does an electric fireplace actually put out?
The same as a plug-in space heater of the same wattage. EIA prints 1 kilowatthour as 3,412 Btu, so a 1,500 W element delivers about 5,118 BTU/h; Dimplex prints exactly that pair for the IgniteXL on 120 V. PuraFlame prints 4600 BTU for its 750/1500 W insert and Touchstone 3,750 BTU for the 1,300 W Sideline 28. Only a 240 V hardwired unit goes higher.
Can an electric fireplace run on an extension cord or power strip?
The manuals say no. Touchstone's Sideline manual says never plug the fireplace into a surge protector, extension cord or relocatable power tap, Dimplex's IgniteXL guide says it is not intended for use with an extension cord, and CPSC says to plug electric space heaters directly into a wall outlet. PuraFlame's manual prints never in its safety list, then allows a 14 AWG cord under 7.87 ft in its install section.
Does an electric fireplace need its own circuit?
Dimplex's IgniteXL guide recommends a dedicated, properly fused 15 A circuit and requires one if the breaker trips after installation. Touchstone and PuraFlame both specify a 120 V 15 A circuit with no other appliances on it. ESFI's booklet puts a 15 A circuit at 1,800 W and recommends staying under 80 percent, 1,440 W, which a 1,500 W heater alone exceeds.
Can the flames run without the heater?
On every unit documented here, yes. Touchstone's Sideline 28 page prints flames with no heat and heat with no flames, Touchstone's Fireplug Pro 29 page says the flame is usable without the heater, and the Dimplex XHD manual says the flame effect can be on with the heat off. The flame-only draw is not printed by any maker, so this page does not state one.
Which electric fireplaces print a UL or ETL listing?
Of the documents opened for this page, only the Dimplex IgniteXL installation guide prints a listing: UL Listing File Number E71416. The Touchstone Sideline and Fireplug Pro manuals, the PuraFlame Western manual, the Dimplex XHD manual and the Duraflame DFI020ARU manual print no ETL or UL text in the pages read. A mark may be on the unit's label, but this page cites only what the document prints.
Fact sheet and how to cite this page
- Answer
- A plug-in electric fireplace is a 1,500 W heater: EIA prints 1 kilowatthour as 3,412 Btu, so 1,500 W is about 5,118 BTU/h, and 12.5 A on a 120 V circuit. The Touchstone Sideline 28 manual prints 12 A and plug-in only; the PuraFlame Western manual prints 750/1500 W, 4600 BTU and 400 sq ft; the Dimplex IgniteXL XLF74 alone prints a 240 V option at 2,500 W and 8,530 BTU.
- Comparison basis
- Manufacturer manuals and sell sheets for the Touchstone Sideline series and Fireplug Pro series, the PuraFlame Western insert, the Dimplex Multi-Fire XHD and IgniteXL XLF74, and the Duraflame DFI020ARU log set, compared on heater watts, printed BTU, supply voltage and amps, plug-in versus hardwire, form and opening size, flame-without-heat mode, printed lab listing, remote and thermostat, and warranty years; ESFI, CPSC and EIA for the circuit and Btu figures.
- Assumptions
- A standard US 120 V 15 A household circuit; the 1,800 W and 1,440 W figures are ESFI’s for that circuit
- The 5,118 BTU/h figure is arithmetic from EIA’s 3,412 Btu per kilowatthour; Dimplex prints the same number, the other makers print their own or none
- The Amazon Duraflame log-set listing prints no model number, so its row carries the DFI020ARU manual’s figures as the nearest document, not the listing’s own
- Method
- OwnerSpec compared manufacturer-published specifications read on 2026-10-09 and confirmed each listing in stock the same day; it did not install, run or measure any fireplace, prints no fire or injury outcome of its own, and reports only the figures the cited document states.
