If you’re looking to enjoy the outdoors before the cold really sets in, space heaters can make gathering outside more comfortable. “Outdoor space heaters are a great way to warm up areas of your yard or patio so that you can still get together with friends and family even as the days get cooler,” said Bailey Carson, head of cleaning and home improvement at Handy.

Ideal for the bedroom or other small spaces, this space heater has three quiet options — high, low and fan mode. “There are 11 different temperature settings and a convenient carry handle,” added Natalie Barrett, service quality supervisor at Nifty Cleaning Services. “The safety features are also great.” Lasko's newer Electric Cyclonic Ceramic Console Heater includes a multi-function remote and two different quiet heat settings, as well as a sleep timer and other notable features.

Van Tuijl’s overall top pick for bedrooms goes to the KopBeau indoor propane space heater. This oil-fueled convection model has four heating modes, a remote and modern safety features.

For large spaces, Van Tuijl recommends the Lifesmart infrared space heater with a maximum 1500-watts high setting.

Other space heaters to consider

Lasko Electric Tower Heater

Rather than a traditional fan design used in many of the options above, this Lasko space heater features a bladeless design like that of Dyson models. It's equipped with a slew of safety features, including a safe touch surface and an automatic shut-off switch. With its quiet oscillating mode, the sleek tower can evenly distribute heat in rooms up to 300 square feet.

This space heater can reach up to 70 degrees Fahrenheit in three seconds and features side to side oscillation for increased heat distribution. Additionally, it comes with three heating modes and includes overheating protection sensors, as well as an automatic off switch.

What is a space heater and do you need one?

Space heaters are portable devices designed to heat single rooms rather than entire houses, explained Arie Van Tuijl, a licensed home inspector and founder of Home Inspector Secrets. “The great thing about space heaters is that homeowners can use them on an ‘as-needed’ basis without turning up their HVAC thermostat,” he said. “In fact, homeowners may want to lower the thermostat if you only want to heat up a single room and save on energy costs.”

Space heater benefits

In addition to their main function of heating things up, space heaters could prove their value in a variety of other ways.

Space heaters work faster. A space heater takes less time to distribute heat and warmth within an area compared to an HVAC system, explained Wiseman. “Central heating often takes some time to reach a set temperature,” he said. “It's a convenient way that you can quickly raise the room temperature and add warmth to any space needed.”

Space heaters are consistent. Space heaters can also maintain the same temperature in a space for as long as you want, allowing you to easily and quickly turn it off and cut off the heat.

They come in many options to answer many needs. From indoor and outdoor space heaters to a range of available sizes and styles available, myriad space heater models can allow you to keep warm in different ways — and at different price points.

Space heaters might save you money. Instead of paying to heat up an entire house and keep it warm, space heaters act as a supplement to your main HVAC system to increase the temperature in the specific area you’re spending time in.

“The main advantages of a space heater are that it will cut down your utility expenses and provide you with the right room temperature when you need it,” Barrett said.

Types of space heaters

There are three main types of space heaters, each designed to heat up your space through a different method. Radiant heaters are usually used to warm up people, convection heaters warm the actual air in a room and a combination heater gives you a bit of both options, explained Carson.

Radiant. Rather than warming the air in an entire room, radiant heaters quickly turn electricity into radiant energy to heat objects or people in front of it. “They are best if you want to heat an area very quickly, and are usually used as ‘spot heaters,’ meaning they would only heat a specific area [they] pointed at,” said Wiseman.

One relevant advantage of these heaters for anyone working from home is that they are silent, designed with minimal moving parts . That also means they are less likely to break down. Having said that, they can also be a fire hazard as they get hot — and they might not be the best for your sleeping situation. “Unfortunately, they usually have an orange glow and may not work well in bedrooms,” added Van Tuijl.

Convection heaters. Convection units rely on hot air rising and cold air falling to silently disperse the heat without a fan. Although these space heaters take the longest to warm a room, they are ideal if your goal is even heat distribution. Common convection models include baseboard and oil-filled heaters. “However, convection heaters may not be suitable for homes with small children because they get hot to the touch,” Van Tuijl noted. “These units also usually come with remotes and can oscillate direction.”

Combination heaters. These heaters utilize a fan to disperse heat so they work on the faster side but aren’t silent. “The nice thing about these heaters is that they don't get hot enough to become a fire or burn risk and there is no annoying orange glow,” said Van Tuijl. “ However, a big negative of fan-based space heaters is that they can dry out the skin while making a background noise.”

How to shop for a space heater

The first step when shopping for a space heater is figuring out the size of the area you plan to warm. For smaller rooms (which are typically considered 120 square feet or less), Van Tuijl generally recommends buying a space heater that is in the 500-1000 watts range, and between 1000 and 1500 watts for larger rooms. Some other key features to look out for while shopping include:

  • Energy efficiency. You’ll want to compare efficiency between models to help ensure you don’t increase your electricity bill too much.
  • Noise level. Some units are louder than others. If you’re shopping for a bedroom or where you’ll be working during the day, that’s something to keep in mind. One resource for finding devices that are especially quiet is Quiet Mark, which tests and awards products based on their noise output.
  • Safety features. Space heaters can be potential fire hazards so don’t overlook any built-in features designed to lessen that chance. “Make sure to buy one that has protective grills as well as auto-shut off capabilities [in case] the heater tips over or overheats,” said Carson.
  • Warranty. Don’t forget to look into warranty options. “This way, you can protect your investment in case anything happens,” added Wiseman.
