Customer Review: “Had others I bought years ago. But couldn’t find them. So glad Amazon had another. They work extremely well and are safe. They have an overheat plug that will shut it down. The temp is accurate. Not noisy. Doesn’t dry out air. I have used these for my parrots at night so I didn’t have to jack up the heat. I did notice they remember settings after a power outage—huge plus!” – Maria G.
Customer Review: “These are exceptional heaters—they provide great heat using up very little space. What I consider one of the best features is unlike others, if the power goes out when it comes back on they start back up and remember the temperature setting. I’ve used these for years and they have a long service life.” – Robert H.

Frequently Asked Questions
Q: Can a 1500W space heater really heat 700 square feet?
A: Yes—if it has efficient airflow (like oscillation) and a quality PTC element. Most 1500W heaters are rated for 300–700 sq ft, but results depend on insulation, ceiling height, and outdoor temps.
Q: Is it safe to leave a space heater on overnight?
A: Only if it has tip-over protection, overheat shutdown, and is placed on a stable, flat surface away from flammable items. Models like the Dreo and duraflame meet these safety standards.
Q: Do space heaters increase your electric bill significantly?
A: A 1500W heater running 8 hours uses about 12 kWh—roughly $1.50–$2.50 per day, depending on your rate. Using ECO mode or timers can cut usage by 30–50%.
Q: What’s the difference between ceramic and infrared heaters?
A: Ceramic heaters warm air quickly and are great for enclosed spaces. Infrared heaters warm objects directly and work better in drafty areas—but most models here use ceramic tech for balanced performance.
Q: Should I buy a heater with a remote or app control?
A: Remotes add convenience for adjusting settings from bed or couch. App control is nice but often unnecessary unless you want scheduling or voice integration.
