Best Space Heaters

Space heaters are a category where reviewer consensus actually matters — output, real-world noise, and safety features vary widely between models that look identical on a spec sheet. The picks below synthesize what RTINGS-adjacent testers, mainstream tech publishers like CNET, retailer verified-purchase reviews from Best Buy and Home Depot, and long-running threads on r/BuyItForLife and r/Appliances have said about the current top sellers. The DREO lineup dominates the candidate pool, so we surface where individual DREO models meaningfully differ rather than treating them as one product.

Frequently asked

5 questions
What's the safest type of space heater for a bedroom?
Across the reviewers we read, ceramic PTC heaters with tip-over protection, overheat shutoff, and a programmable thermostat are the most commonly recommended for bedrooms. r/BuyItForLife and r/Appliances threads also call out oil-filled radiators as the quietest option for overnight use, since they have no fan. Whichever style you pick, reviewers across sources stress plugging directly into a wall outlet — never a power strip — because of the 1500W draw.
How many square feet can a 1500W space heater actually heat?
Most experts we surveyed (CNET, TechGearLab, and DREO's own retailer listings) describe 1500W ceramic heaters as effective for roughly 150–300 sq ft of well-insulated space. Reddit users in r/KitchenStack and r/candidconsumer report meaningful warming in a typical 200 sq ft room, but multiple sources caution that drafty rooms, high ceilings, or open floor plans will significantly reduce that effective coverage.
Are DREO space heaters actually quiet enough for a bedroom?
Retailer reviews on Best Buy and Walmart and a CNET write-up of the larger DREO tower models repeatedly cite quiet operation, with DREO citing ~34 dB on lower settings. r/BuyItForLife users comparing DREO to De'Longhi note DREO is the quieter of the two on fan settings, though anyone sensitive to fan noise tends to gravitate to oil-filled radiators instead.
Is a more expensive space heater meaningfully better than a $25 model?
Reviewers are split. Budget units like the GiveBest 1500W earn 4.4 stars across 80,000+ Amazon reviews and do the basic job, but high-trust testing from TechGearLab and CNET points to better thermostat accuracy, quieter fans, oscillation coverage, and more robust safety sensors on mid-tier ($50–$90) models. The consensus is that cheap heaters heat fine, but pricier units hold temperature more precisely and run quieter.
Can space heaters trip a circuit breaker?
Yes — this is one of the most consistent warnings across r/AskElectricians and r/Appliances threads. A 1500W heater pulls about 12.5 amps, which is close to the limit of a standard 15-amp circuit. Reviewers and electricians both recommend running the heater on a dedicated outlet, never daisy-chaining it on a power strip or extension cord, and checking the outlet for warmth during use.
