Ranked #2 in Best Electric Fireplaces

Duraflame 3D Infrared Electric Fireplace Stove (DFI-5010)

4.5

5 sources3 derived$259.99

This is the freestanding stove that every major home publication ends up recommending, and it earns it on heat rather than looks. Family Handyman actually ran it as a backup when their oil tank went dry and reported the living and dining rooms noticeably warmer half an hour after setting the thermostat to 70F. The infrared quartz element is rated at 5,200 BTU for zone heating up to 1,000 square feet, which is the highest figure here, and there is no installation beyond screwing on the legs. The compromises are physical: it is short, the legs are plastic, and the remote will not change the temperature.

Strengths

— Family Handyman's tester set the thermostat to 70F and felt the living and dining rooms change within thirty minutes
— Infrared quartz element rather than a bare coil, which Duraflame credits for keeping more natural humidity in the room
— Assembly is fitting four legs with a Phillips screwdriver, about five minutes start to finish

Watch-outs

— Stands just under two feet tall, which Family Handyman's tester wished were taller so the top could hold anything
— The remote switches the heater on and off but cannot change the thermostat setpoint, which has to be done at the panel
— Popular Mechanics flags plastic legs on an otherwise metal body, and Reviewed's con list reads "Not all metal"

Ranked #3 in Best Electric Fireplaces

PuraFlame Klaus 33-inch Electric Fireplace Insert

4.5

3 sources2 derived$419.99

The Klaus is Bob Vila's overall pick for the category and Popular Mechanics' best traditional insert, and both awards come down to the front face: double glass doors, a mesh curtain, and a three-sided brick liner behind a resin log on a grate. It is a conversion product, meant to drop into a hearth or a framed cutout, and the flat bottom means it can sit straight on the floor of an opening with no hearth built under it. Popular Mechanics puts the output above 5,000 BTU for rooms up to 400 square feet. The reservations are consistent across both publications: the crackling audio does not convince, the control panel sits where you can see it, and there is no hardwire option.

Strengths

— Double glass doors and a mesh curtain in front of the fire, so the front face reads as a real firebox rather than a lit panel
— Flat bottom lets it sit directly on the floor of a hearthless opening with no plinth to build
— Three-sided brick liner behind a resin log on a grate, which is what Bob Vila built its overall pick around

Watch-outs

— Bob Vila's single con is that the crackling sound effect is not very realistic
— Popular Mechanics calls the front-mounted control panel conspicuous on an insert designed to look traditional
— Cannot be hardwired, so the cord has to be planned for or hidden

How they stack up

Duraflame 3D Infrared Electric Fireplace Stove (DFI-5010)

Rated for more than twice the floor area of the Touchstone Sideline 50-inch (80004) while costing a fraction as much, and it needs no framing at all — the trade is a much smaller fire and no app or voice control. Against the PuraFlame Klaus 33-inch Electric Fireplace Insert it is a portable appliance rather than a firebox conversion, and it is the only unit in this lineup you can move between rooms.

PuraFlame Klaus 33-inch Electric Fireplace Insert

Shares its width with the PuraFlame Western 33-inch Electric Fireplace Insert but is about four inches shorter and closes the fire behind glass doors and a mesh screen instead of leaving the hearth open. Unlike the Touchstone Sideline 50-inch (80004) it needs an existing opening rather than a stud wall, and it has none of the app or voice control the Touchstone Sideline Elite 50-inch (80036) offers.
