How We Chose the Best Space Heaters for Bedrooms 

We researched the most sought-after space heaters for bedrooms in their respective categories and discovered that the best models are determined by their type, fuel source, wattage and British thermal units (BTUs), coverage area, and other special features included by top brands. (For a more detailed discussion of BTUs, read the Heating section that appears after our product reviews.)

To satisfy a range of preferences, we included fan, convection, micathermic, and infrared heaters. While a few select heaters are nonelectric and rely on propane and kerosene for fuel, many are electric and low-maintenance. No matter the type, these top picks emit heat outputs of 5,100 to 10,000 BTUs, and the electric models rely on 900 to 1,500 watts to function. And since our top picks can heat between 144- and 750-square-foot spaces, finding the right size unit for each bedroom should be easy.

When it comes to safety, many of these heaters have tip-over and overheat protection features to prevent burns and fires. For convenience, many models boast digital control panels or remote controls to adjust the oscillation, heat settings, and air speed to suit user preferences and save energy. And select picks in this lineup can be adjusted via Wi-Fi connection with a smartphone or tablet.

What to Consider When Choosing a Space Heater for Bedrooms

Before purchasing a space heater for a bedroom, keep some important considerations in mind. Give each point some thought to help choose the best space heater for bedroom warmth in your home.

Type 

Several types of space heaters are on the market, each of which produces heat differently. These include convection, infrared, micathermic, and fan heaters.

  • Fan heaters have electric coils that produce heat and spinning fan blades that push warm air into the room. Position these electric heaters on a desk or dresser and aim them toward the bed while you sleep.
  • Convection heaters produce heat with electric coils, ceramic plates, or oil-filled fins. As the heat rises, it pushes cold air down toward the heater. Convection heaters then warm the cold air, which rises and pushes colder air back down.
  • Infrared heaters warm objects in front of the heater, not the air around it. Once those objects warm sufficiently, they become like small, radiant heaters themselves, releasing heat energy into the space. Infrared heaters are excellent for producing localized heat, but some models struggle to produce a uniform amount of heat. Moreover, the bright glow of the coils can affect light sleepers.
  • Micathermic heaters use electric coils to warm a sheet of mica sandwiched between them. They produce both convection and radiant heat.

Safety

Safety is the most important consideration when using a space heater, especially overnight in a bedroom. For example, a heater placed too close to a curtain, bedspread, or other combustible object could cause a fire. It’s critical to keep space heaters away from objects. Also, ensure that smoke and carbon monoxide detectors are working.

To help mitigate danger, many manufacturers install safety features on space heaters, the most important of which may be the tip-over switch, which shuts off the unit if it falls over. Also, space heaters that use combustible fuels sometimes feature low-oxygen cutoffs that disable the unit when enough oxygen isn’t available for safe combustion. Prior to using any type of space heater, read and understand the manufacturer’s instructions.

It’s also worth noting that a space heater should not be plugged into an extension cord. The heaters draw too much energy, which can overheat the cord or trip a breaker. They need to be plugged directly into a wall outlet, and some may require you to unplug other items on the same circuit to avoid tripping a breaker.

Heating

Nearly all heaters complete some type of convection cycle, which means they can heat most rooms if sized correctly. Luckily, most bedrooms are relatively small compared to wide-open great rooms or the primary living space, which means nearly any space heater will do.

Space heaters come in either watt ratings (labeled “W”) or British thermal units (BTUs). Almost all electric space heaters are rated for either 750 or 1,500 watts; the smaller size is suitable for small rooms like a bedroom or home office, and the larger size accommodates larger spaces. As to BTUs, a heater that produces 9,000 BTUs is typically plenty for even a large bedroom.

Energy Efficiency

Whether a portable heater uses electricity, a fossil fuel, or some other type of fuel source, ideally a space heater should be energy efficient. While heating an entire home with space heaters would not be an efficient use of energy, using one to heat a bedroom while the rest of the house stays at a lower temperature can actually save money.

In homes without heating zones, the temperature throughout the entire home might need to be quite high to make the bedroom comfortable overnight. With a space heater, the rest of the home’s heating system can hover at energy-efficient temperatures while the bedroom stays toasty warm.

Noise Level

Any extra noise in the bedroom can affect a light sleeper’s rest. On a space heater, typical fan levels measure about 35 to 45 decibels, equivalent to a quiet background conversation. Oil-filled heaters usually make bubbling sounds that are clearly audible within the room.

Product labels don’t often list noise level, so if absolute silence is necessary, a micathermic heater might be the way to go. This type of heater doesn’t use a fan or oil, so the heat is produced quietly and comfortably.

FAQs

Now that you’ve learned a bit more about using space heaters to heat the bedrooms in your home, some new questions may have popped up. Ahead, we answer some of the most frequently asked questions about the best space heaters for bedrooms.

Q. Can a space heater catch fire?

It’s highly unlikely that the space heater itself will catch fire, but a fire can result from a space heater touching combustible materials. Make sure space heaters are kept away from any combustibles.

Q. Do space heaters create carbon dioxide?

Kerosene or propane heaters can create carbon dioxide, but if running properly, they don’t pose a threat of poisoning. However, users should have operational carbon monoxide detectors in their homes.

Q. Is it safe to leave a space heater on all night?

Yes, as long as the area is clear of combustible materials, and carbon monoxide and smoke detectors are installed, running a space heater at night is safe. Installing a wall-mounted space heater may be one of the best ways to control the risk, as you’ll know to keep that area free of dangerous items.

Q. How long does a space heater last?

Generally speaking, space heaters are only used for a few months a year, so they can last for years. Maintain them by cleaning any filters and coils and keeping them free of moisture.
