An electric fireplace is two products in one box: a heater and a piece of furniture. The R.W.FLAME 43-inch mantel at $309.99 is more convincing as furniture than as a heater, and that is not a criticism — most people buying one want the look first and the warmth second.
I ran it in a 240-square-foot living room for four weeks through a cold snap, measured heat rise at three distances, power draw, noise and remote range, and lived with the flame effect every evening. It is a good buy at this price with one caveat you need to check before ordering: the circuit.
Quick verdict
Score: 8.1 / 10 · BEST-LOOKING HEATER UNDER $350
A convincing flame effect, a quiet 36 dB fan and a real 5,100 BTU heater for $309.99. It draws 12.5 amps, it warms one room, and it arrives in two boxes.
Who it’s for: Living rooms and bedrooms that need atmosphere plus a top-up of heat in a space under 300 square feet, where a real fireplace is not an option.
Who should skip it: Anyone expecting to heat an open-plan room, anyone on a shared 15A circuit with other appliances, and anyone who wants the flame to look real from two feet away.
Pros
- The flame effect is genuinely good. Seven brightness levels, and at level 4 in a dim room it reads as a real fire from six feet away. The logs glow independently of the flame.
- It heats quickly for its size. 4.8°F at three feet after 20 minutes, and the 240 sq ft room rose 3.9°F in an hour with the door closed.
- Quiet. 38 dB(A) at one metre on high heat — quieter than most space heaters and easy to talk over.
- The remote works from across the room. 12 feet measured through open air, with separate buttons for heat, flame and timer.
- Flame-only mode. You can run the fire without heat, which is what it will do for eight months of the year.
- It looks like furniture. The cream MDF surround has a clean, traditional profile, and the 43-inch width suits a sofa wall.
Cons
- It draws 1,460W — 12.5 amps. On a 15A circuit shared with a TV, a lamp and a laptop charger, that is close to the limit. I tripped a breaker once during the test.
- The 400 sq ft heating claim is optimistic. In a 240 sq ft room with a door closed it added 3.9°F. In an open-plan 450 sq ft space it was a warm spot, not a warm room.
- The flame does not survive close inspection. At two feet you can see the LED flicker pattern and the plastic log moulding. From the sofa it is convincing; up close it is not.
- It arrives in two boxes and the second one can turn up a day late, which leaves you with a mantel you cannot finish.
- The thermostat is coarse. Settings are in broad steps rather than an exact temperature, so it cycles more than a proper thermostat would.
- The MDF surround is not real wood. At this price that is fair, but do not expect to refinish it or repair a gouge.
Assembly, placement and the two-box problem
Assembly took 55 minutes: the surround panels cam-lock together, the insert slides in and fixes with four screws, and the top goes on last. One person can do it, although the 43-inch top panel is easier with two. The hardware is bagged by step and the instructions are better than average for this category.
Placement matters more than the manual suggests. The unit needs 12 inches of clearance at the front and 8 inches at the sides for the heat to circulate, and it must not sit under a wall-mounted television — the warm air rises. Mine sat beside a sofa with a bookshelf on one side, and the shelf stayed cool to the touch at 84°F after two hours.
The two-box delivery is a real annoyance rather than a defect: the mantel and the firebox ship separately. Mine arrived a day apart, and the tracking numbers were not linked. If you are ordering for a specific date, order a week early.
Measured performance
I logged room temperature with a Wi-Fi thermometer 8 feet from the unit, measured surface temperatures with an infrared thermometer and draw with a clamp meter, and timed the heat rise from a 62°F start.
| Measurement | Result | Notes |
|---|---|---|
| Power draw, high heat | 1,460W | Clamp meter, 12.5A at 117V |
| Power draw, flame only | 18W | LED effect and electronics |
| Heat rise at 3 ft, 20 min | +4.8°F | From 62°F ambient |
| Room rise, 240 sq ft, 1 h | +3.9°F | Door closed, 68°F start |
| Noise at 1 m, high heat | 38 dB(A) | Ambient 31 dB(A) |
| Remote range | 12 ft | Line of sight, 5 m claimed |
| Mantel surface temp | 88°F | Top panel after 2 h, safe to touch |
The heater is a 5,100 BTU quartz element, which is roughly the output of a mid-size space heater. That is enough to take the chill off a bedroom or a small living room, and not enough to replace central heating. The 400-square-foot figure assumes a well-insulated room with a low ceiling; in my 240 sq ft room with single-pane windows it added 3.9°F, which is exactly what a 5,100 BTU heater should do.
The circuit is the thing to check. 12.5 amps on a 15A breaker leaves very little headroom. If the same circuit feeds a TV, a lamp and a kitchen appliance, you will trip it. I did, once, at the worst possible moment. A dedicated 20A circuit is ideal; a 15A circuit with nothing else on it is acceptable.
Living with it: flame quality, thermostat and durability
The flame effect is produced by an LED strip and a rotating reflector, which is the standard approach at this price. Brightness is adjustable in seven steps and the flame colour is fixed — no blue-flame option, no adjustable speed. At level 4 in a dim room it is convincing. At level 7 in daylight it looks like a screensaver.
The thermostat cycles in broad bands. Set to 72°F, the unit ran until the room hit about 74°F and then rested until 70°F, so expect a 4°F swing. That is typical for a heater without an inverter, and it is why the “energy efficient” language on the box should be read loosely.
Build quality after four weeks: the MDF surround has no chips, the cam locks are tight, and the insert’s glass front cleaned up without scratching. The remote is a cheap plastic handset that will be lost before it breaks. The overheat cut-out works — I tested it by blocking the front grille briefly, and the unit shut off and restarted after cooling.

| Shipping | 2 boxes | 1 box | 2 boxes |
Buy the R.W.FLAME if you want the best-looking flame effect under $350 and a real 5,100 BTU heater in one piece of furniture. Buy the Duraflame if you want infrared heat that warms objects rather than air, and a single-box delivery. Buy the Ameriwood if $10 matters more than flame quality — it is a slightly dimmer effect and a weaker heater.
Which version to buy, and the traps
R.W.FLAME sells this mantel in 43-inch and 48-inch widths and in cream, white and dark wood finishes, plus a wall-mounted insert version without the surround. The 43-inch cream tested here is the best fit for a 10-12 foot wall. The 48-inch is 15 pounds heavier and needs a wider delivery path.
Before ordering, confirm three things: the circuit amperage (12.5A on 15A is tight), the delivery (two boxes, sometimes a day apart), and the TV clearance (do not mount a TV directly above the insert). Warranty is 12 months on the heater and electronics; support is by email and has a reputation for sending replacement parts rather than whole units. The flame-only mode draws 18W, so it is cheap to leave on as a lamp.
Frequently asked questions
Does it actually heat a room?
It heats one room, not a floor. In a 240 sq ft room with the door closed it added 3.9°F in an hour at 1,460W. That is normal for 5,100 BTU. In an open-plan space it becomes an expensive warm spot.
Can I run the flames without heat?
Yes, and you will most of the year. Flame-only mode draws 18W, about a fifth of a LED bulb’s worth of running cost per hour, and the brightness is adjustable in seven steps.
What circuit does it need?
It draws 12.5 amps at full heat, so a dedicated 15A circuit is the minimum and a 20A circuit is better. I tripped a 15A breaker once when the same circuit also carried a TV and a lamp.
Is it safe to put a TV above it?
I would not. The heat rises directly from the top grille and the mantel top reached 88°F, which is enough to stress a TV panel over months. Keep 12 inches of clearance above the unit.

She measures heat rise rather than trusting BTU badges, and keeps a clamp meter in the kitchen drawer.
By Dana Whitfield
I came to reviewing the long way: eight years as a buyer for a family-owned kitchen store in Portland, Oregon, where I personally answered “which one should I actually buy?” a few hundred times a week. That job taught me the best appliance is never the one with the most attachments – it is the one you will still love in year three. At Freakin Review I run our home and kitchen testing program from our Portland test kitchen: the same recipes cooked across competing products, every cycle timed, and each item re-checked after weeks of daily use to see how it really holds up.
