If you’ve ever worked in an office or lived in a building that stays drafty all year long, you’re likely familiar with the search for a great space heater. Along with keeping you warm and cozy, these small devices are a great way to cut down your heating costs, and save energy while you’re at it. Rather than adjusting your entire building’s heat system, the best energy-efficient space heaters will add warmth just to the rooms you use the most.

Not sure what to look for in an energy-efficient space heater? We spoke with home health and safety experts and we’re sharing their advice below, plus their most helpful tips on how to warm up your space, and our top picks for the best energy efficient space heaters.

What to look for in an energy-efficient space heater.

In general, space heaters can be divided into two main types: convection and radiant. Convection heaters warm the ambient air by passing it over a heating element, whereas radiant heaters emit infrared radiation to warm people and objects nearby, not the surrounding air. In general, radiant space heaters, commonly referred to as infrared heaters, are among the most energy-efficient options, because it takes less energy to emit radiation than heat the air.

There are certainly energy-efficient convection heaters, too, but the EPA doesn’t currently label space heaters as an ENERGY STAR-qualified product–which can make choosing an energy-efficient space heater a bit difficult.

Experts recommend taking a few key features into consideration. First, it’s important to pay attention to the heater’s wattage rating. The higher the wattage, the more electricity or energy it will consume. As a rule of thumb, space heaters with a fan tend to consume more energy than those without.

“Look for a space heater with multiple heat settings, and ideally an energy saving or ECO-mode. That way, you can use less energy by only heating the room to the temperature you need,” says Cate Walter, Director at Rhino Safety, experts in health, safety, and fire risk management.

Home fire safety expert and director of the Fire Risk Assessment Network, John Smith, adds that features such as overheat protection and an adjustable thermostat can help you safely heat your space, while ultimately saving energy by maintaining your desired room temperature.

Lastly, you’ll want to find a space heater designed specifically for the room size you plan to use it in. This will help ensure that you get the most efficient heating for your needs.

How we picked:

Some space heaters are naturally more energy efficient based on the type of heater, others offer energy-saving and ECO settings. We prioritized heaters with these features.


We dove into the reviews (the good and the bad) to be sure we are recommending quality products that customers tend to love.


We know everyone’s budget is different, so we included options at a variety of price points.

If you’re in the market for a quality and durable space heater this is a great option, as ceramic heaters are generally a more efficient type of convection heaters.

Another wall-mountable option, this energy-saving space heater automatically adjusts the temperature and power settings to maintain a consistent and comfortable temperature. The dual-lateral fan offers improved heat distribution to warm any small room quickly and evenly. It’s also more aesthetically pleasing than many others on the market, so you can keep your home the sanctuary that it is.

Most commonly praised for its design, effectiveness, and (lack of) sound, this heater gets a lot of positive reviews on Amazon. One reviewer says, “dead silent 99.999% of the time, but uses a fraction of the electricity” versus other electric radiators.

This heater’s maximum electricity output is only 400 megawatts, compared to other space heaters with outputs of 1,500 megawatts or more. As a result, this space heater can provide consistent warmth in small spaces, using less energy at a lower cost.

The EconoHome convection heater is designed to be mounted to the wall and can even be painted to match the room aesthetic. Although it’s lacking digital temperature control, it does offer a plug-in thermostat to help you customize the heat settings to your liking.

While it does get a lot of positive feedback on Amazon, the overall rating is a bit lower than we’d prefer: 3.7 out of 5 stars. It seems any negative reviews are all regarding a smell, but the majority of customers argue that there is no such odor. One person writes, “I was a little nervous buying this because of all the negative comments about the strong odor, as I consider myself to be somewhat sensitive to such things, but I unpacked it, plugged it in and waited for the worst and it’s completely fine! No strong odor at all and it seems to heat up quite nicely!” and others who notice the smell say it goes away fairly quickly.

There aren’t a ton of reviews yet on the company’s website, but they’re almost all positive. Customers love that this heater warms their space and say it’s so quiet they almost forget they have it on. A couple of people note that it takes a bit longer than they’d like to warm up.

Who should buy a space heater

Space heaters are a great way to quickly and easily heat a smaller room in your home. They can be especially helpful if you have a drafty space, or want to save on energy costs by only heating the rooms you use the most.

On the other hand, if you’re looking to heat a large space, or multiple rooms throughout the house, our experts advise that space heaters are not the best option.

Below are a few other options to consider if you’re looking to heat your home this winter:

Electric fireplace heaters: Electric fireplace heaters are a great way to add extra warmth to your home. Not only do they provide heat, but they also add a cozy ambiance. Many electric fireplace heaters come with remote controls, so you can easily adjust the temperature from anywhere in the room.Wood burners: Wood burners are environmentally friendly and can help you save on energy costs. While they require some maintenance, like regular cleaning, they’re a great way to add extra warmth to your home.Pellet heating stoves: Pellet heating stoves are a great alternative to wood burners. They’re easy to operate and require very little maintenance. Pellet heating stoves are also environmentally friendly and can help you save on energy costs.

More tips to keep your space warm.

“Making sure your home is effectively insulated can be an effective way to ensure that heat remains in the home. Invest in attic insulation, weatherstripping or caulking around windows, window insulation sheets, draft excluders and more to help better regulate temperature at home,” says Walter.

When home updates aren’t an option, there are other ways to give you some warmth without breaking the bill.

“Ultimately, the best way to keep warm in your home will depend on your individual preferences and comfort level,” says Smith. So find what works best for you and your family, and prepare to snuggle in during these chilly, winter months.


Do space heaters raise electric bills a lot?

In general, space heaters are best to warm a person or a small space–not an entire house. They can raise your electric bills quite a bit, if you don’t make other changes at home. To utilize these devices as an energy-efficient option, lower your thermostat and use a space heater in the room you spend most of your time in.

Is it cheaper to turn up the thermostat or use a space heater?

The cheaper option will depend on the size of your home and the number of people. If you are trying to warm an entire home, it may be cheaper to turn up the thermostat, but if you are focusing on one or two spaces in a larger home, a space heater will likely be the most cost-effective option.

Are there any dangers or safety risks associated with space heaters?

Space heaters are a leading cause of home heating equipment fires, according to the National Fire Protection Association (NFPA). Other potential hazards include burn risk to young children and pets, and carbon monoxide poisoning for certain types of space heaters, says Walter.

The takeaway.

Energy efficient space heaters are an easy, eco-friendly way to warm up a small space. Whether you’re looking for a model to take the chill out of your home office or bedroom, or you want to sit outside on a chilly night, this list has got you covered.
