Comparison · Types
They cost the same per hour and produce the same heat. The difference is where that heat goes — and which one you want is decided entirely by the room.

Ceramic heaters warm the air and circulate it with a fan, so the whole room comes up evenly over ten to twenty minutes. Infrared heaters emit radiant heat that warms you and nearby surfaces almost instantly, but only where they point. Both cost the same per hour at the same wattage.
Ceramic (PTC). Current passes through a ceramic element with a positive temperature coefficient — its resistance rises as it heats, which naturally limits its own temperature. A fan draws room air across it and pushes the warmed air out. You are heating the air, and the air is heating you.
Infrared quartz. Current heats a quartz tube, which emits in the infrared band. Infrared passes through air without warming it much and is absorbed by the first solid thing it hits — you, the floor, the furniture. Those surfaces then warm the air around them slowly. It is the same mechanism by which sunlight through a window warms your face on a cold day while the room stays cold.
| Ceramic (PTC) | Infrared quartz | |
|---|---|---|
| Heats | The air, then you | You and surfaces directly |
| Time to feel it | 10–20 minutes for the room | Seconds, if it is pointing at you |
| Directional? | No — the fan distributes it | Yes, strongly |
| Noise | Fan noise, typically 45–55 dB | Silent if fanless; many cabinet units have blowers |
| Best room shape | Enclosed, normal ceiling | Large, drafty, high-ceilinged, or open |
| Persistence after switch-off | Short — warm air disperses | None — but surfaces stay warm |
| Moves dust | Yes, it is a fan | No, if fanless |
| Efficiency | ~100% | ~100% |
| Cost per hour at 1,500 W | 27.5¢ | 27.5¢ |
Cost computed at 18.34¢/kWh (EIA, June 2026). The identical bottom two rows are the point.
Dust and allergies. A ceramic heater is a fan, and a fan in a room moves whatever is on the floor into the air. People with dust sensitivities notice this within a day. Fanless designs — infrared panels, oil-filled radiators, mica panels — do not do it.
Shadowing. Radiant heat does not go around things. Sit with your back to an infrared heater and your front is cold. Put a coffee table between you and it and your legs are cold. This is obvious in retrospect and surprising in practice.
Surface temperature. Quartz elements run extremely hot and glow. Cabinet-style infrared units enclose that behind a grille and a housing; bare-element units do not. The three-foot clearance rule is not negotiable with either, but it is especially not with an exposed element.

Coverage computed at 10 W/sq ft, average insulation, 8 ft ceiling. Draw computed as watts ÷ volts. Neither figure is a manufacturer claim.
Top pick · A whole living room
The rare heater whose published coverage claim survives the arithmetic: 1,500 W is a genuine 300 sq ft at 10 W/sq ft, and Dreo publishes that number rather than implying more.

Who it is for
A living room, bedroom or den at or under 300 sq ft with average insulation and an 8-foot ceiling, where you want to set a temperature and stop thinking about it.
What it is not for
A garage, an uninsulated basement, or anything over about 300 sq ft. It is not under-powered — 1,500 W is the plug-in ceiling — the room is simply too big for one outlet.
2 · The published numbers
The one listing in this category that publishes its amp draw and its noise level, which is exactly the arithmetic everyone else leaves you to do — 12.5 A and 39 dB, both stated.
| Published specification | |
|---|---|
| Rated power | 1,500 W at 120 V |
| Current draw | 12.5 A (published) |
| Noise | 39 dB (published) |
| Element | Infrared quartz tube plus PTC |
| Thermostat | Electronic, 50–85°F |
| Other | 12-hour auto-off timer, IR remote, caster wheels, 19 lb |
| Heat type | Infrared quartz |
| Maker’s coverage claim | None published — the coverage figure above is ours |
| Safety listing | No listing mark published in the listing text; check the cabinet's rating plate for the UL or ETL mark. |
Who it is for
A reader who wants to compute the load rather than trust a claim: the published amp draw and decibel figure make it the easiest unit on this site to check.
What it is not for
A 15 A circuit shared with anything else, and not a small room where a 19 lb cabinet on wheels is in the way.
3 · A large room on a budget
A long-running 1,500 W tower with a digital thermostat, an 8-hour timer and a remote — the cheap end of the category without the missing-safety-feature problem the cheap end usually has.
| Published specification | |
|---|---|
| Rated power | 1,500 W at 120 V |
| Maker's coverage claim | None published — listed as “for large rooms” |
| Controls | Digital thermostat, remote, 8-hour auto-off timer |
| Height | 29" |
| Safety | Cool-touch housing, overheat protection |
| Heat type | Ceramic (PTC) |
| Maker’s coverage claim | None published — the coverage figure above is ours |
| Safety listing | Lasko does not publish a listing mark on the Amazon listing text; check the unit's own rating plate for the UL or ETL mark before you use it. |
Who it is for
Someone heating one main room who wants a thermostat and a timer and is not willing to pay a premium for a metal cabinet.
What it is not for
A room with a toddler or a curious pet. Without a child lock, the controls are one press away from full output at floor height.

4 · Getting the heater off the floor
Wall-mounted, which removes the entire tip-over failure mode rather than mitigating it — and Wi-Fi scheduling means it can heat a bathroom before you get in it.
| Published specification | |
|---|---|
| Rated power | 1,500 W at 120 V |
| Published output | 5,200 BTU/h |
| Mounting | Wall-mounted |
| Control | Wi-Fi app, remote scheduling |
| Element | Infrared quartz |
| Heat type | Infrared quartz |
| Maker’s coverage claim | None published — the coverage figure above is ours |
| Safety listing | No listing mark published in the listing text; check the rating plate for the UL or ETL mark. |
Who it is for
A bathroom, a small bedroom, a workshop corner — anywhere floor space is gone and a heater on the ground is a hazard.
What it is not for
Renters who cannot drill, and rooms where you want the heater to move with you.

Neither in general. Infrared warms you and nearby surfaces almost instantly and suits large, drafty or high-ceilinged spaces. Ceramic warms the air evenly and suits enclosed rooms. At the same wattage they cost the same to run.
Not per hour. Both are about 100% efficient, so 1,500 W is 1,500 W. Infrared can result in lower consumption because you may be comfortable at a lower setting without raising the room's air temperature.
Infrared makes you feel warm faster — within seconds if it points at you. Ceramic raises the room's actual air temperature faster, because a fan distributing warm air heats the volume more effectively than radiant heat does.
Yes, with the same rules as any heater: three feet of clearance, direct wall plug, tip-over and overheat cutoffs. Quartz elements run very hot, so enclosed cabinet designs and wall-mounted panels are preferable where children or pets are around.
How a PTC element self-limits its temperature, and which rooms ceramic heaters actually suit.
Heats you rather than the room — excellent where every other type struggles, and the shadowing problem.
Heating the air versus heating the things in it — the distinction under every other comparison.
A two-car garage needs about 9,000 W. An outlet gives you 1,500. What to do instead.
The four units that get closest to a 300 sq ft room — and the two-heater arithmetic nobody publishes.
A correction, not a product pick: equal wattage means equal cost, and here is what actually varies.
