The best bedroom heater depends on your sleep preferences, but oil-filled radiant heaters and ceramic fan heaters are the top choices.
For a bedroom, the safest space heaters feature no glowing elements and include automatic shut-off and tip-over protection. Oil-filled radiators (like those by De'Longhi) and modern ceramic convection heaters with cool-touch housing (such as the Dreo Solaris) are generally considered the safest options for overnight use.
Best Room Heaters for Good Health
Infrared heaters provide direct, targeted warmth to people and objects using radiant heat (similar to sunlight), making them highly efficient for drafty spaces or personal use. Ceramic heaters use convection, heating the air and circulating it around the room with a fan, which is better for warming an entire enclosed space.
Most indoor heaters tend to dry out the air, lowering indoor humidity levels. Dry air can cause irritation to the respiratory tract, leading to symptoms like dry throat, cough, and nasal congestion. For individuals with chronic respiratory diseases like asthma or COPD, low humidity can exacerbate symptoms.
Infrared heaters directly warm objects and people in a "line-of-sight" manner. While highly efficient for targeted heating, their main drawbacks include a lack of retained warmth once turned off, vulnerability to blocking by furniture, and ineffective heating in uninsulated spaces.
How Much Does It Cost to Run a 1500W Infrared Heater? (Real Examples & Calculations) A 1500W infrared heater costs between $0.18 and $0.24 per hour to run in the U.S., depending on your electricity rate. That equals roughly $1.80–$2.40 per day (if used 10 hours), about $55–$72 per month, or $650–$870 per year.
The best heater for a bedroom is the Dreo Solaris Slim H3 Space Heater or the Lasko 1500W Ceramic Tower Heater. Both are safe, quiet, compact, and feature built-in thermostats and tip-over auto-shutoff, making them ideal and budget-friendly for small-to-medium bedrooms.
Are ceramic space heaters safe? Yes, like any listed space heater, ceramic heaters are safe as long as you operate them safely. These heaters warm up your space by blowing air across heated ceramic plates instead of metal coils, so keeping the area around the space heater unobstructed is important.
The best room heater depends on your space and heating needs. The Dreo Solaris Slim H3 is the best overall for fast, quiet heating. For energy efficiency, the Envi Smart Wall Heater is top-tier. If you want budget-friendly performance, the Amazon Basics Ceramic Heater is ideal.
Again, using a heated blanket or mattress protector can help give an extra boost of warmth. If your bedroom gets very cold in the winter, a fan heater can make it warmer fast. You should also check to see if there are any drafts in your home, and seal these up to stop heat from escaping.
Consumer Reports tests space heaters primarily on room heating ability, spot heating, and strict fire and safety criteria, such as overheat protection and tipping tests. Highly rated models often cost around $75 to $100 and feature auto-climate control and tip-over shut-offs.
Sealed combustion heaters are much safer to operate than other types of space heaters, and operate more efficiently because they do not draw in the heated air from the room and exhaust it to the outdoors. They are also less likely to backdraft and adversely affect indoor air quality.
A 1500-watt heater typically heats a room up to 150 square feet (as a primary heat source) or up to 250 square feet (if used as supplementary heat alongside a central system). This capacity is ideal for small to medium-sized bedrooms, home offices, or dorms.
Never leave a space heater running for long periods of time, and especially not overnight; it is best to use them intermittently; depending on your situation, a suggested practice would be to turn it off/unplug it for 10 minutes every hour if you depend on its use for longer periods.
Cheapest ways to heat your home
While ceramic heaters are excellent for quickly warming small, localized areas, they have notable drawbacks. Their primary disadvantages include a lack of heat retention, a limited heating range, noise from built-in fans, and safety hazards if misused.
Are infrared heaters safer than ceramic heaters? Yes. Infrared heaters have no exposed heating elements or fans, reducing fire hazards. Also, since they don't circulate air, they don't circulate allergens.
The safest indoor heaters are oil-filled radiant heaters and modern ceramic heaters with smart safety features (like tip-over auto-shutoff and overheat protection). They eliminate the danger of exposed glowing coils and pose no fire risk from carbon monoxide, making them ideal for bedrooms, children, and pets.
Similarly, “convector heaters warm the air which then circulates around the room, making them effective for heating the whole space”. For smaller spaces, Horne recommends fan or halogen heaters: “Fan heaters blow hot air directly at you, offering a quick burst of warmth when needed.
6 Important Things to Consider Before Buying a Room Heater
The best indoor heater depends on your room size and heating style. For large rooms, the Dreo Space Heater is a top-performing, quiet ceramic option with wide oscillation. If you want safe, gentle, long-lasting heat, the DeLonghi Dragon oil-filled radiator is highly recommended. For a budget-friendly pick, the Lasko 754200 is a classic.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
If your home uses electricity for central heating, the cost is likely still cheaper than running space heaters. According to Scerbo, “Buying a space heater for every room would increase the electricity bill more than if you had just bumped up the thermostat.”
An electric space heater rated at 1,500 watts will put out the same amount of heat regardless what you pay for it.
