Most Economical Space Heater: Consumer Reports | Top at $75

For the full breakdown, see our best Economical Space Heater guide.

Nearly half of the top-rated space heaters in Consumer Reports’ latest tests cost $75 or less, proving that high performance and a reasonable price go hand in hand. The most energy-efficient choice is a radiant infrared heater, which warms people and objects directly instead of heating the air, wasting less electricity in the process. All standard plug-in models draw 1,500 watts — the safe limit for a 15-amp household circuit — and .

What Consumer Reports Reveals About Price and Performance

Consumer Reports tested space heaters ranging from $18 to $500 and found no connection between a high price and strong performance. Many of the highest-scoring models clustered near the low end of that price range. The lesson is straightforward: you do not need to spend hundreds to get a heater that performs well and keeps your electricity bills manageable. Focus on the heater’s type, efficiency, and safety certifications rather than the dollar amount on the tag. One of the most common and costly mistakes shoppers make is assuming a higher price guarantees better heating performance — Consumer Reports’ data shows this assumption is simply wrong.

Why Infrared Heaters Are the Most Economical Choice

Infrared heaters convert electricity directly into radiant heat. Instead of warming the air and letting it rise toward the ceiling, they warm the surfaces, furniture, and people in the room. This direct transfer wastes far less energy, which means your electricity bill stays lower over time.

For spaces like garages or workshops, gas heating is often more cost-effective than any electric option. But inside your living areas, an infrared electric heater is the most economical way to lower monthly heating costs without sacrificing comfort.

Buying an Economical Space Heater: What to Check First

Always confirm the heater carries a certification label from UL Solutions, ETL, or CSA. These marks mean the unit has passed independent U.S. safety testing — something your home insurance policy may require. Never exceed 1,500 watts on a standard 15-amp household circuit; a higher-wattage heater can trip the breaker or create a fire hazard. Place the heater on the floor, never on a table or shelf where it could tip over. Keep it at least three feet clear of curtains, bedding, furniture, and anything flammable. Plug it directly into a wall outlet — extension cords and power strips overheat easily under the draw of a space heater. Inspect the power cord for fraying or damage before each use. Turn the heater off whenever you leave the room, and never run it while you are asleep.

FAQs

Is infrared the most economical type of space heater?

Yes. Infrared (radiant) heaters are the most energy-efficient option available because they warm people and objects directly rather than heating the air. This direct method wastes less heat and lowers your electricity costs compared to fan-forced or ceramic models.

How much does it cost to run a 1500-watt space heater per day?

Your actual cost will vary depending on your local rate per kilowatt-hour and how often the heater cycles on and off during use.

What size room can an infrared space heater effectively warm?
