Space heaters are a fast and economical way to warm up your home when temperatures dip — and they can be a beneficial tool to keep on hand in case of emergencies. Whether it’s a drafty bedroom or outside on the patio during a cool night, these portable devices allow you to bring an effective boost of heat wherever you need it.

To determine the best space heater for you, I spoke to home and safety experts about the benefits of space heaters, what features to look for when shopping for one and how to use them safely.
How I picked the best space heaters
There are several factors to consider when choosing a space heater. Here’s everything I kept in mind when making this list:
- Type: The main types of space heaters are radiant, convection and combination. Radiant heaters primarily warm what’s directly in front of them with infrared heat rather than your entire home or room. A convection heater is more suited to heating a room or large space. A combination heater has a fan that propels hot air outward to heat a home — they’re louder than radiant and convection ones, but less of a fire hazard, according to our experts. All three types of space heaters are included in the list below.
- Testing: Like with many home appliances, space heaters are tested by independent quality assurance agencies, mainly the Underwriters Laboratories (UL) or the Electrical Testing Laboratories (ETL), to ensure they meet the agency’s safety requirements. All of the space units below have either UL or ETL certification.
- Wattage: The power of a space heater is measured in watts. The higher the wattage, the more powerful it is and the larger of a space it can heat, according to Arie Van Tuijl, a licensed home inspector and founder of home-maintenance website Home Inspector Secrets. Tuijil generally recommends buying a space heater that is in the 500-1,000 watts range for smaller rooms (which are typically considered 120 square feet or less), and between 1,000 and 1,500 watts for larger rooms. The list below includes space heaters with wattage ranging between 500 and 1,500.
- Safety features: Space heaters can be potential fire hazards, so it’s important that they include safety features like protective grills and an auto shut-off feature. Many of the space heaters listed below have an auto shut-off feature, tip-over safety feature or protective grill.
- Warranty. Most space heaters come with a warranty so you can be sure that the product is returnable or replaceable if something happens to it, according to Glenn Wiseman, sales manager of Top Hat Home Comfort Services in Ontario. I included all of the warranties for the units below, where possible.

How to shop for a space heater
Once you’ve decided that you want a space heater, factor in the aspects below to choose the exact one that’s best for your space and situation.
Decide on a type
Choose between a radiant, convection or combination space heater. Depending on your living situation, one may be better for you than the other. If you have a small space, choose a radiant heater and if you have a large space to warm up, a convection may be best. Additionally, if you don’t mind the noise, a combination space heater is good for families with small children since they’re less of a safety hazard, according to our experts.
Consider where you’ll put it
In addition to the type of space heater you want, you should consider where you’ll put it, which will determine what size and shape is best. Plus, if you’re only getting one to heat a small room, this will further make it easier to decide on a type.
Noise level
Some space heaters tend to make a lot of noise, some more than others. Keeping this in mind, I made sure to include units from brands that mention minimal to moderate noise. units are louder than others. If you’re shopping for a bedroom or home office, 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.
Take energy efficiency into account
Space heaters are generally more energy efficient than central heating since you’re only heating up the room and some space heaters are also more energy efficient than others. Since space heaters don’t have Energy Star ratings — which independently certifies a product’s energy efficiency — the easiest way to determine if your unit conserves energy is by checking whether it has features like an adjustable thermostat and auto shut-off option that can maintain a certain temperature and prevent a room from overheating, according to the Department of Energy.
What should I know about space heaters and safety?
The U.S. Consumer Product Safety Commission estimates more than 25,000 residential fires are associated with the use of space heaters every year, and an estimated 6,000 people go to the emergency room for burn injuries associated with contacting the hot surfaces of heaters.
To prevent fires and injuries, many experts recommend looking for space heaters that are tested by independent safety laboratories, like Intertek (ETL) and Underwriters Laboratories (UL). Joel Hawk, principal engineering manager for small appliances at UL, tells us that these laboratories test space heaters based on nationally recognized safety standards, and add that space heaters can be very safe as long as they’re used per the instructions.
While the features that can certify products as “reasonably safe” vary from one space heater to the other, Hawk says his engineers typically look at whether the product adequately responds to overheating conditions or a malfunction (and if it permanently shuts down in unsafe conditions) and whether there are features that prevent electric shock, like suitable insulation and heat-resistant cords. Another important attribute that’s tested is what Hawk calls “personal injury” — UL tests to ensure the unit won’t catch fire and that there aren’t surfaces hot enough to cause a thermal burn or moving parts that may cause injury if they’re touched.
While independent testing and built-in safety features from the manufacturer can mean a space heater is functionally safe, our experts note that common sense also plays a big role in safety. The CPSC recommends the following safety tips to minimize the risk of fire:
- Never leave a heater operating while unattended or while you are sleeping.
- Keep combustible material like papers, clothes, beds and curtains at least 3 feet from the front, sides and back of the heater.
- Avoid powering the heater with an extension cord or power strip.
- Place the heater on a stable, level surface where it won’t be knocked over.
To prevent electrical shocks, always keep electric heaters away from water, and never touch an electric heater if you’re wet.
