Best Space Heaters of 2021
CR's tests reveal the speediest and safest models
Space heaters provide that extra warmth you may want in a drafty room or chilly office. It’s a product category that hasn’t seen much innovation over the past few years, but in Consumer Reports’ space heater tests, we found some nonboxy models that look good and work well. And you’ll find many good choices in our ratings that cost $100 or less.
First question: What do you want the space heater to do? Heat just you—or warm up your family room? Our tests have found that not all models do both well.
Another thing space heaters don’t do well? Save you money.
Most models are unlikely to produce the cost savings that some manufacturers claim. In fact, they’re less efficient than central heating systems. So while a space heater is relatively small, it can leave you with a big utility bill if you don’t use it wisely.
How We Test Space Heaters
We test space heaters for heating a standard-sized room in 15 minutes and directly heating a person—spot heating—in the same amount of time. “Our spot-heating test uses a mannequin wired with sensors,” says test engineer Chris Regan, who oversees our space heater lab. “We want to know how your body will feel when you’re sitting within 4 feet of the appliance."
We also test space heaters for safety, including how hot the surface gets (so that you don’t burn your fingers) and whether they get so hot that they can ignite a piece of fabric (imagine your curtains). In the past, we’ve called out space heaters that did poorly on our fire-safety test.
Below, grouped alphabetically by task, are ratings and reviews of space heaters that excel at both heating a room and directly heating a person, as well as models that aced either one task or the other. For more choices, see our full space heater ratings.
