Why Trust Forbes Vetted
At Forbes Vetted, we want to help you and your family stay comfortable during the winter—without spending an arm and a leg on heating costs. We carefully researched the different types of space heaters available today to figure out which options will work best in large rooms, and also consulted with two heating experts to ensure that our findings were accurate.
Our expertise isn’t limited to outside knowledge, either. Members of our team have tested (or personally used) products from many of the brands included on this list, as well as a variety of fans and air purifiers.
How We Chose The Best Space Heaters For Large Rooms
After thorough research and consulting with experts, we looked for space heaters that are powerful enough to provide warmth in large rooms. We prioritized models that can effectively be used in spaces of 300 square feet or more, and some of the options listed can heat rooms as large as 1,000 square feet. We also selected options in a variety of styles, including tower, oil-filled and wall-mounted space heaters, allowing you to select the option that will work best in your home.
What To Look For In The Best Space Heaters For Large Rooms
There are several types of space heaters that you’ll encounter as you shop, including ceramic, fan, infrared and oil-filled heaters:
- Ceramic Heaters: This type of space heater works by heating up ceramic plates inside the unit, and typically, a fan then blows the warmth out into your room. “Ceramic heaters are the most common heater types because of their safety and versatility,” says Rukky Ojakovo, business unit director of heaters at Lasko. They’re also generally compact and heat up quickly.
- Infrared Heaters: While ceramic heaters warm the air in your home, infrared heaters actually warm up the objects around them. These heaters emit electromagnetic rays that warm up furniture, walls and even people around them. Infrared heaters are the most energy-efficient option, but they can only send heat in one direction.
- Fan Heaters: This type of space heater is generally the most affordable, and they operate similarly to ceramic units. The main difference is that they use a metal filament or coil to produce heat, not a ceramic plate.
- Oil-Filled Heaters: As their name suggests, oil-filled space heaters (often called oil-filled radiators) have fins that are filled with oil, and the fuel is warmed up via electric heating elements. These units produce radiant heat, and they often stay warm for longer periods after the heater is turned off, making them fairly energy efficient. Oil-filled heaters are also silent, as they don’t have a fan component, but they’re generally bulky and get hot to the touch.
You’ll want to consider the size of your room when selecting a space heater—if you buy a unit that’s too small, it may not be able to warm up the space.
“For larger spaces, consider a tower or whole-room heater to effectively heat the entire area,” recommends Ojakovo. “These heaters distribute heat more effectively across larger areas with larger blower systems and oscillation features, making sure every corner is receiving adequate warmth. This approach will ensure that you get the most out of your space heater for both comfort and efficiency.”
Some space heaters do list their recommended coverage area in square feet, but unfortunately, this isn’t standard across product specifications. If coverage isn’t listed, you’ll want to look at the unit’s size and wattage to get a sense of its heating abilities.
When selecting a space heater, there are a variety of features you may want to prioritize: “Look for safety features such as tip-over protection and overheat shutoff, as safety is paramount,” says Roberson. “Features like adjustable thermostats and timers can enhance convenience, too.”
For large rooms, space heaters with powerful fans and oscillation can help increase their efficiency, moving the warmth around the space.
What Is The Safest Space Heater For A Large Room?
If used incorrectly, space heaters can be dangerous and are a common cause of house fires each year. To safeguard your home and family, it’s crucial to select a model with safety features and ETL certification. Our top recommendation for heating large rooms is the Vornado VMH600 Whole Room Heater. This model boasts a cool-touch exterior, tip-over protection and a 2-stage automatic safety shut-off. Additionally, its low center of gravity enhances stability, reducing the likelihood of accidental tipping.
Nevertheless, even the most reliable space heaters can be hazardous if mishandled. Therefore, it is essential to adhere to safety guidelines when operating these devices. As advised by Roberson, place the heater on a level, non-flammable surface away from walls and objects. Never leave heaters unattended and turn them off when not in use. Keep the surrounding area clear, ensuring that children and pets stay away to prevent accidents.
What Size Space Heater Do I Need For A Large Room?
Our experts advise selecting a space heater that provides 10 to 15 watts of power per square foot of space. However, this becomes a challenge for extra-large rooms, as most residential space heaters typically cap at around 1,500 watts. In such instances, it’s recommended to opt for a unit equipped with oscillation and a powerful fan, enhancing the heater’s ability to warm up a larger area.
For those dealing with the heating needs of an extra-large room, it’s crucial to recognize that even the most potent space heaters have limitations. According to Roberson, “In larger spaces, the heat generated by a space heater might not be distributed evenly, making it challenging to maintain a comfortable temperature throughout the area. If you need to heat a significant space, it’s often more efficient and practical to rely on central heating systems or consider multiple space heaters strategically placed throughout the room.”

Are There Heaters That Last 24 Hours For A Large Room?
Some space heaters come equipped with 24-hour timers for continuous operation. The Dreo Radiator Heater, for example, allows programming to automatically shut off after 24 hours.
Nevertheless, it’s important to note that leaving a space heater unattended, especially while sleeping, is not recommended. If you opt to run your space heater for extended periods, ensure the presence of smoke and carbon monoxide detectors in close proximity. These detectors will alert you to any issues that may arise during operation.
