Space heaters are a great way to add warmth to a single room, without heating up the entire house. These portable small appliances can be placed in any room that needs some extra heat. Space heaters utilize three different types of heating elements: radiant, convection, and combination. A radiant space heater will gradually raise the ambient temperature of a room, while convention space heaters immediately distribute warmth to people and objects in the room.
When shopping for space heaters, be sure to take features into consideration. An automatic tip-over shutoff, protection from overheating, and a cool-touch exterior are ideal safety features—especially in a household with children and pets. Conveniences like an easy-to-read temperature display, digital touchpad, and remote control will certainly enhance the user experience.
Another thing to consider before buying a space heater is the amount of heat it produces. Most 120-volt space heaters crank out up to 1,500 watts of power, ideal for heating rooms between 150 and 300 square feet. However, some models—particularly those with a higher BTU rating—can effectively warm up a larger area.
Here are the best space heaters on the market right now.
Best Overall: Lasko Bladeless Ceramic Heater with Remote Control
Heating Element: Ceramic | Voltage: 120 | Wattage: 1,500 | Power Source: Electric | Dimensions: 8.1 x 27.17 x 9.16 inches | Weight: 9.8 pounds
Easy to use
Remote control for convenience

Does not heat a large room effectively
If you’re looking to heat a small- to medium-sized room, this tower-style heater stands out for its sleek design. Offering 1,500 watts or 1,000 watts of power, it’s recommended for use in rooms up to 300 square feet. The adjustable temperature ranges from 70 to 85 degrees. I tested the Lasko Ceramic Heater and found it easy to use. Thanks to its slim, space-saving profile, I could use it almost anywhere in my house. I appreciated the nice selection of features, which include oscillation, a timer, and a remote control.
The Lasko heater lacks one key safety feature—an automatic tip-over shut-off. However, the tower design is very stable and the plastic housing remains cool to the touch when in use. While this heater did an excellent job warming up the smaller rooms of my home, I would opt for something more powerful to heat my large open-concept living room or basement.
"One of my favorite features is the timer, which allows you to specify the amount of time you want the heater to run. I never had to worry about accidentally leaving it on when I left the house."—Sage McHugh, Product Tester

The adjustable temperature can be set between 50 and 85 degrees. I tested the Dr. Infrared Heater and was very impressed with its performance. It was able to heat my open-concept living area and primary bedroom evenly and efficiently. With its more industrial look and large heating capacity, it’s also well suited for a basement.
If you’re using the heater in a room that’s not monitored consistently, safety features are an important consideration. This unit will shut off automatically if it overheats, tips in any direction, or if the inlet air duct is obstructed. It comes with a remote control, but the heater must be turned on manually.
"I was very impressed with its performance and its ability to heat my large primary bedroom evenly. I set the temperature at 70, and the room heated up in less than a half-hour, even with outdoor temperatures near freezing."—Sage McHugh, Product Tester

What to Look for in a Space Heater
There are many types of space heaters, but the most common, least expensive, and safest models are compact space heaters with fans. Other relatively safe compact space heaters have ceramic plates or coils. Models with ceramic plates are self-regulating to avoid overheating. Models with coils are often exposed and get very hot, posing a safety risk, especially to those with children and pets. Some floor standing space heaters run off infrared heat or oil. Infrared heats up very quickly but does not stay hot. Oil models are very effective, but large, heavy, and more expensive.
Nearly all 120-volt space heaters are rated up to 1,500 watts at the maximum setting, which is suitable for approximately 150 square feet. Avoid models with less wattage — the price is often comparable and they are much less effective. To heat a larger room, you’ll need to purchase multiple space heaters or consider a larger, more professional-grade heater.
Look for models with automatic shut-offs or temperature regulators, particularly if your space heater will be running frequently or overnight. Always buy models that meet U.S. safety standards. Look for labels that indicate the unit has been tested by recognized labs like UL, ETL, or CSA. And never use an extension cord with an electric heater — choose a model with a longer power cord if proximity to an outlet is an issue.
