Space heaters provide that extra warmth you 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 many models that look good and work well. You’ll find many good choices in our ratings that cost $100 or less.

Before you buy, ask yourself what 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.

More on Space Heaters

Think twice about turning down your thermostat and using a space heater to warm certain areas. You may see modest savings by supplementing the heat in just one room and keeping the others cooler, but that could be impractical.

Safety is another consideration. It’s safest to keep space heaters on the floor rather than on a table. That means a remote control can come in handy, especially if the knobs and dials are on the bottom of the unit (less stooping over and squinting at the settings). Then there’s noise. A machine that makes a racket can be annoying if you’re running it while trying to watch TV. Most of the space heaters in our ratings earn a Very Good or Excellent rating in our noise test, and those that did worse typically had other shortcomings.

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 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.
