Staying warm in the winter can be a real challenge, especially if you don’t have an HVAC system. On the one hand, even if you do have central air and heat, you’ll risk incredibly high electricity costs (not to mention wasted power!). On the other, many space heaters won’t warm you up enough, and you’ll have to pile on the blankets.
Luckily though, there are options: Energy-efficient space heaters. You can warm up quickly and easily without turning on the heat throughout the rest of your home, leading to less energy and lower bills.
Which kind of space heater should you go for? Most safety-certified heaters are electric, which include oil-filled radiators, ceramic heaters, and infrared space heaters. Oil-filled radiators are the oldest kinds, the ones you probably imagine your grandparents lugging around—but they provide long-lasting warmth. Ceramic heaters are the most popular since they’re light, effective, and can quickly warm up a space. Finally, infrared space heaters work via “line of sight,” which means you’ll save energy in empty rooms—but they can also use more energy.
Ultimately, you’ll want to compare your needs and preferred heating style with the options out there, but we’ve found five energy-saving space heaters that are a great starting point. This list includes all three types (oil-filled radiator, ceramic, and infrared), and we’ve noted the eco-features, safety certifications (i.e., CSA, UL, or ETL), and the room size capacity of each one.
Finally, if you need some quick ‘n easy ways to maximize heat if a space heater isn’t an option, consider thermal curtains, draft guards, and window insulation. Stay warm this season.

Out of the many heater options out there, Lasko was the one we’ve seen again and again (and have in our own homes!). The Lasko Ceramic Tower Heater is our favorite energy-saving pick since it comes with AutoEco technology. The AutoEco feature is an automatic thermostat that “maintains comfort while using less energy,” perfect for warming up a room but not overusing electricity. There are three heat settings, optional oscillation to spread the warmth, and built-in safety features as well as a remote control so you can snuggle in without having to get up.

Filled with oil, this portable space heater can keep a room warmer longer than most ceramic or infrared heaters. Best yet, the ECO Plus technology “selects the ideal power level based on the difference between the current room temperature and the set temperature.” (Uh, yes, please.)
