Dr Infrared Heater Portable 1500W
After testing a dozen space heaters for my drafty living room, the Dr Infrared Heater Portable Space Heater has earned its spot as the best electric heater for 800 sq ft. This cherry-red unit isn’t just another pretty appliance; it’s a legitimately powerful dual-system machine that actually warms up my entire open-concept area without sounding like a jet engine.
Pros
The real magic is in its dual heating system, combining an infrared quartz tube with PTC technology. It throws serious, comfortable heat—rated around 5200 BTU—and I felt it quickly. The super quiet 39 dB blower is a game-changer for watching TV, and the handy remote lets me adjust everything from the couch. I also love the safety peace of mind from its tip-over and overheat protection, plus the convenience of caster wheels and a 12-hour auto shut-off timer.
Cons
The main catch is its power appetite. At 1500 watts and 12.5 amps, you need to be mindful of what else is on the same circuit to avoid tripping a breaker. While the wheels help, at 24 pounds it’s not exactly feather-light to carry up stairs. The electronic thermostat works well but has a limited range from 50 to 85 degrees, so if you like a very specific temperature outside that window, you might be slightly disappointed.

COSTWAY PTC Ceramic Tower Heater
Finding the best electric heater for 800 sq ft often means choosing between raw power and thoughtful features. The COSTWAY PTC Ceramic Tower Heater, positioned at number two in our ranking, makes a compelling case by blending serious heating performance with a surprisingly cozy aesthetic.
Pros
- Rapid, widespread heat distribution is a major strength. The 1500W PTC ceramic element heats up almost instantly, and the 80-degree oscillation effectively pushes warmth across a large room.
- The three-dimensional flame effect is genuinely realistic and can be used independently of the heat, creating ambiance year-round.
- Operation is incredibly convenient thanks to a full-featured remote control and a simple touch panel, enhancing its user-friendly design.
- It feels secure with robust safety features including tip-over and overheat protection, all backed by CSA certification.
Cons
- While powerful, its effective heating area is listed for 250 sq. ft., so it may struggle as the sole heat source in a true 800 sq. ft. open space without strategic placement or supplemental heating.
- The remote control requires two AAA batteries, which are not included—a minor but notable omission.
- The cooling fan function is basic; it’s fine for air circulation but isn’t a substitute for a dedicated floor fan on hot days.
This COSTWAY heater excels as a versatile and stylish supplemental heat source. It delivers fast, oscillating warmth for sizable rooms and its unique flame feature adds wonderful atmosphere. For consistent primary heating in very large, open 800 sq. ft. areas, you might need to pair it with another unit, but for most large bedrooms or living rooms, it performs admirably.

Dreo Portable Space Heater
Finding the best electric heater for 800 sq ft can be a challenge, but the Dreo Portable Space Heater stands out as a strong contender for effectively warming larger personal spaces and open floor plans.
Pros
The heater’s primary strength is its impressive airflow and rapid heating. It pushes warm air across a room noticeably faster than many compact models. The wide-angle oscillation does an excellent job of distributing that heat evenly, preventing hot and cold spots. For a unit with this power, its low operational noise in the quieter modes is a significant benefit, making it suitable for bedrooms and home offices. The included remote and clear digital interface offer convenient, precise temperature control, which is essential for maintaining consistent comfort.
Cons
While powerful, this heater truly excels in areas up to 300 square feet; very large or drafty 800 sq ft spaces may require supplemental heating on the coldest days. Its taller, slim profile is generally stable, but the design feels slightly more top-heavy compared to some squatter ceramic heaters, so careful placement is advised. The gold color option is distinctive, but it may not blend seamlessly with every home decor style.
The Dreo heater delivers robust performance for its size, combining effective heating power with user-friendly features. It represents a solid value for those needing reliable warmth in medium to large rooms.

Smart Mica Convection Heater Wifi Control
The market is flooded with electric heaters promising to warm large spaces, but the Smart Mica Convection Heater with WiFi Control stands out by delivering silent, app-enabled comfort in a remarkably slim profile.
Where It Excels
- This model is significantly quieter and more compact than traditional oil-filled radiators or blower-based convection heaters, making it ideal for bedrooms and home offices.
- Its smart app integration is more advanced and user-friendly than many basic programmable thermostats found on competitors, offering true remote control from anywhere.
Where It Lags
- It offers fewer physical control options than some simpler models from s like De’Longhi, relying more on the touch panel or app.
- The heating range, while excellent for its size, may require more time to fully stabilize temperature in a full 800 sq ft open area compared to a more powerful dual-fan ceramic heater.
Pick this if silent operation and smart home integration matter most. For the fifth spot in our ranking, this heater is a perfect match for tech-savvy users who want set-and-forget warmth with zero noise and a sleek, space-saving design that can be mounted on the wall. Its combination of mica convection heat and granular app control is tough to beat for modern, comfortable living.
