Best Energy Efficient Electric Heaters for Lower Bills and Steady Warmth
The best energy efficient electric heater is the one that heats the space actually in use, holds that heat, and runs on smart controls instead of a fixed dial. This roundup covers five models that approach that goal from different angles: a budget ceramic fan, two smart wall and panel units, a classic oil-filled radiator, and a mica infrared panel. It suits renters who want plug-in warmth, homeowners willing to mount a heater on the wall, and anyone replacing a drafty room’s space heater with something smarter. The overview below puts the specs side by side so a choice can be made in a minute; the reviews explain the trade-offs behind each one.
Overview of the Picks

|---|---|---|---|
| DREO Space Heater, 1500W | 70° oscillation, 12H timer, ECO mode | Fast spot heat in a large room | Budget |
| IP24 Wall Mounted Heater | 28dB quiet, app and Alexa control | Quiet, permanent wall heat | Budget |

DREO Space Heater with Thermostat, 1500W
Type: Portable electric space heater
Power: 1500W
Oscillation: 70°
Timer: 12 hours
Modes: ECO mode, thermostat control
Safety: ETL-certified
Controls: Remote control
DREO Space Heater with Thermostat, 1500W
This is the value pick of the group. A 1500W ceramic element plus 70° oscillation spreads warm air across a large room quickly, and the ECO mode lets the thermostat take over once the target temperature is reached so the heater is not running flat out the whole time. The 12-hour timer and remote make it practical for a bedroom or living room, and ETL certification covers the basic safety box. It is the most popular model here for a reason: it does the fast-heat job at the lowest entry point.
It suits renters and anyone who wants heat that follows them from room to room. The trade-off is that a fan-driven heater makes audible noise and dries the air slightly, so it is a weaker fit for light sleepers or a study where quiet matters.
Trade-off: Fast fan heat comes with fan noise, and the plastic housing reflects the budget price.
DREO IP24 Wall Mounted Heater
Type: Wall-mounted electric heater
Heating: 11.5 ft/s air output
Noise: 28dB quiet operation
Controls: App, remote, digital thermostat
Modes: ECO mode
Smart home: Works with Alexa
Mounting this unit on the wall frees floor space and puts the heat where it is needed without a cord across the room. The 28dB rating is the headline: it is quiet enough to sit in a bedroom or home office without competing with conversation. App and Alexa control plus a digital thermostat and ECO mode mean schedules and temperature changes happen from a phone rather than a dial, which is the practical side of efficiency.
It suits homeowners and long-term renters who can drill a mount and want permanent, discreet heat in a large room. The trade-off is installation: a wall-mounted heater is not something to move between rooms, and the initial setup is more involved than unboxing a portable unit.
Trade-off: Wall mounting is permanent, so the heater is tied to one room once installed.
Dr Infrared Heater DR-968 Portable Space Heater
Type: Portable infrared space heater
Power: 1500W
Finish: Cherry
Form factor: Floor-standing portable unit
Heating style: Infrared radiant heat
Dr Infrared Heater DR-968 Portable Space Heater
Infrared heat warms objects and people rather than the air, so this unit feels warm quickly without waiting for a whole room to come up to temperature. The 1500W draw is standard for the class, and the cabinet-style build with a cherry finish reads more like furniture than an appliance. It is a good fit for a living room or den where the heater stays put and people sit within its line of sight.
It suits buyers who want a portable heater that looks presentable and delivers radiant warmth to a seating area. The trade-off is that infrared heat is directional: it warms what it faces, so a large open-plan space will not feel evenly heated the way it would with a convection or oil-filled unit.
Trade-off: Radiant heat is directional, so the warmth fades once a person moves out of its path.
De’Longhi Oil Filled Radiator Heater EW7707CM
Type: Oil-filled radiator heater
Power: 1500W
Form factor: Portable floor unit
Heating style: Full-room radiant and convection heat
Safety: Built-in safety features
Best rooms: Office and bedroom
De’Longhi Oil Filled Radiator Heater EW7707CM
Oil-filled radiators are the quiet option: there is no fan, so the only sound is the oil warming and the metal ticking as it expands. This 1500W model heats a room steadily and keeps radiating after the element cycles off, which is where the energy-saving reputation of the category comes from. The sealed oil reservoir never needs topping up, and the portable cabinet design with safety features suits a bedroom or office where silence matters.
It suits light sleepers, night-shift workers, and anyone who wants background warmth rather than a blast of hot air. The trade-off is warm-up time: an oil radiator takes a while to reach full output, so it is a poor choice for quick, on-demand heat.
Trade-off: Slow to heat up and heavy to move, so it rewards planning ahead rather than instant comfort.
Ballu Mica Infrared Space Heater
Type: Mica infrared panel heater
Mounting: Portable stand or wall mount
Controls: WiFi app, programmable thermostat
Smart home: Works with Alexa
Heating style: Mica infrared
Finish: White
Ballu Mica Infrared Space Heater
This is the most flexible unit in the group. A mica infrared panel can sit on its stand as a portable heater or be mounted on the wall, so the same purchase covers a rental today and a permanent install later. WiFi app control, a programmable thermostat and Alexa support put scheduling and setback in easy reach, which is where most real savings come from. The white panel finish keeps it visually quiet in a living room.
It suits buyers who want smart controls and mounting flexibility in one unit and are willing to pay for both. The trade-off is price: it costs noticeably more than the other picks here, and the premium buys control and versatility rather than more raw heat output.
Trade-off: The highest price in the group, so the smart features have to earn their keep over a cheaper heater.
Before You Buy
- Wattage and circuit load: Every pick here draws 1500W at full output. A dedicated circuit or an outlet not shared with other high-draw appliances avoids tripping breakers.
- Heating style: Fan and ceramic heaters warm air fast; infrared warms people and objects; oil-filled radiators warm a room slowly and silently. Match the style to how the room is used.
- Room size: A large-room rating assumes an open space. A heater placed in a small, closed bedroom will cycle off sooner and use less power.
- Mounting: Wall-mounted and convertible panel units need a suitable wall and, in some cases, a licensed install. Portable units need only floor space and a clear margin around them.
- Controls and scheduling: A programmable thermostat or app schedule does more for efficiency than raw wattage, because it stops the heater running in an empty room.
- Safety features: Look for tip-over protection on portable units and keep all heaters clear of curtains, bedding and furniture.
- Noise: Fan-driven models are audible. Bedrooms and studies usually favor oil-filled or panel heaters.
Frequently Asked Questions
-
What makes an electric heater energy efficient?
Efficiency here is about control and heat retention, not a special element. A thermostat, ECO mode or schedule that stops the heater cycling at full power in an empty room saves more than any single spec. -
Is infrared or oil-filled heating cheaper to run?
Both draw 1500W at full output, so running cost depends on how long each stays on. Oil-filled radiators hold heat after switching off, while infrared heats people directly and can feel effective at a lower setting. -
Can a 1500W heater run on a normal household outlet?
Yes, on a standard 15-amp circuit, provided nothing else heavy is drawing from the same circuit at the same time. Older wiring should be checked before adding a second heater. -
Which pick is quietest for a bedroom?
The oil-filled radiator is silent apart from the oil warming, and the wall-mounted DREO is rated at 28dB. Fan heaters are the loudest option. -
Do smart heaters need WiFi to work?
No. App and Alexa control are conveniences layered on top of manual controls, so the heater still runs from its own panel if the network drops.
Bottom Line
For most buyers, the DREO Space Heater with Thermostat is the best energy efficient electric heater to start with: 1500W of fast heat, a 12-hour timer, ECO mode and a remote at the lowest price in this group. Those who want silent overnight warmth should step up to the De’Longhi oil-filled radiator, while the Ballu mica panel earns its premium for anyone who wants WiFi control and the option to wall-mount later.
