We’ve placed the Dr Infrared Heater Portable Space Heater at the top of our list of the best space heaters for large rooms for a good reason. Although the heater uses the same wattage as others on the market, it generates more heat than any other model.

Easy Controls: One of the best features of the Dr Infrared Heater Portable Space Heater is that, even with all of its bells and whistles, it’s easy to control. You can control the heater at a distance, as you can turn it off, change your desired temperature, and program your heating settings without having to leave your couch. You won’t even need to get up to turn off the heater as you can program a 12-hour timer so that it turns off automatically. 

Noise: The unfortunate thing about space heaters is that they are often pretty noisy while running — but you should have to sacrifice quiet for warmth. When this heater is on, you’ll barely hear it, thanks to its state-of-the-art 7-inch blower. 

This blower generates high pressure to move more air at a lower speed and reduce sound levels. Because this is a corded model, you can plug it into just about any electric source with its 72-inch long cord.

Stand out: Although the Dr Infrared Heater Portable Space Heater has many great features, what makes it stand out as the best portable space heater for large rooms is the safety features that make it ideal for families.

The Duraflame 3D Infrared Electric Fireplace Stove is unique in ability and design as it is a space heater for large rooms, but doesn’t share the same aesthetic as others on the market. Instead of looking like a small machine or electronic device, this heater is designed as a fake fireplace to create ambience and cozy vibes.

Heating: In addition to being a stunning addition to any living room, this 5,200 BTU electric fireplace heater can heat up to 1,000 Sq. ft. While other heaters with a smaller radius can heat a bedroom or home office, this model is one of the best living room heaters. The only downside is that the heater does make noise when it runs. 

This heater has a remote to change the temperature, but this remote is the only way to update the heat settings. You’ll want to keep this remote charged and in arm’s reach.

Size: This is a very compact and portable model, but at 4.1 lbs, it is significantly smaller than the standard heaters on the market. Because this model uses zone heating, it only heats the zones you want warm and toasty. This prevents the machine from generating unneeded heat and using excess and expensive energy. 

Safety: This heater is safe for the family and your air quality. Its infrared quartz heat can work with your favourite air purifier humidifier to maintain your air’s natural humidity to avoid drying out space. Simultaneously, the machine’s overheat protection ensures that the heater will automatically turn off before overheating. Homeowners will love the adjustable and digital thermostat that will allow you to tweak your room’s temperature without having to move out from under your blankets.

The Stand Out Feature: The stand out feature of this heater has to be its patent-pending 3D flame effect technology. The heater features realistic flames with five adjustable colors, brightness, and speed settings. You can even have the flames going without heat if that’s your thing! This is the best heater for living rooms because it’s aesthetic and functional. The flames may be noisy, but they bring the warm and cozy vibes in more ways than one.

The Standout Feature: This heater’s standout feature is a toss-up between its wide-angle oscillation and energy-saving ECO mode.

If your house gets too chilly in the winter, you’ll want to call in the Lasko 758000 as your reinforcement 

Ease of use: The Lasko 5538 Ceramic Tire Heater is great for low-tech individuals because the electronic controls are easy to use and the adjustable thermostat works like a charm. There’s a seven-hour timer included, as well as two heat settings. If you don’t feel like controlling the settings yourself, you can just let the thermostat control setting take over.

Heating & Functionality: This heater boasts two heating settings to keep you toasty in the colder months. The heater’s louver is great for directing air up and out but has a hard time directing air downwards because of its location.

Buying Guide

What to Consider When Buying a Space Heater For Large Rooms

Physical Size: Space heaters are available in a wide range of sizes, so it’s essential to determine the right size heater for you. The dimensions of the room or area you’re planning to use the heater will determine where you need a small space heater or a large room space heater.

Ease of Setup: How much time do you want or have to spend setting up the heater? Electric heaters for large rooms generally come ready to use out of the package (or at least require minimum effort to set up), but gas heaters often demand the purchase of additional fixtures to make them work. Consider how easy the system is to set up. 

Mounting: Some heaters come with fixtures that let you mount them on the wall or ceiling, which can be highly useful in small spaces. That said, some may prefer a heater on the floor to keep their feet warm and toasty while they work or watch TV.

Temperature Controls: The space heaters on the market offer a huge spectrum of control levels. Determine whether you just want low and high comfort settings or are interested in more specific degree levels.

Thermostat: It’s always a good idea to look for a heater with a thermostat. Some heaters include a built-in thermostat that will keep track of the room temperature and adjust its output levels accordingly.

Safety Features: Safety features like an automatic shutoff if the machine gets tipped over or overheating prevention are essential for stress-free use. After all, when heaters overheat or don’t have these safety features, they can cause harm and injury.

Heat Level of Casing: Sometimes, the heater’s outer casing can get very hot to the touch while it is in use. If you have pets or small children, you will want to invest in a heater that boasts protection to prevent the casing from heating. 

Timer: If you often forget to turn off appliances, find a heater with a built-in timer that will turn the machine off for you in case you forget. Various models offer different timer settings or have a programmable timer. After all, leaving your heater on for too long can be a fire hazard [1].

Noise Level: Many space heaters are noisy when they run because of the fan. If you are sensitive to noise, try to find a heater that doesn’t have a fan, or read our reviews to identify the quieter ones. A helpful hint is that radiative heaters tend to be less noisy because they don’t use fans. 

Remote Control: Some models include a remote control that allows you to adjust temperature settings from across the room. This is especially convenient when you are in bed or watching TV.

Aesthetics: There is a wide selection of heaters on the market that vary in shape, size, and colour. Decide on the type of aesthetic you are looking for. For example, tower-shaped heaters are sleek and less of an eyesore than propane burning devices. You can even find heaters that look like fireplaces or old-fashioned radiators!

Range: Some models have a better radius than others and can better heat larger rooms. Consider your room’s size and the heater’s capacity to fill to heat the entire area.

Power: How powerful is the machine? How much heat can it give off at a given time? The larger your room, the more powerful you will want your heater to be.

Types of Space Heaters

There are different types of space heaters that you can choose from. Each of these heaters uses different methods to heat the air in a room: 

Convection Space Heaters: Convection or oil-filled space heaters use a heating element to heat the air or oil. A fan may be used to move this heated air into the room. The heater may also oscillate to spread the heated air around. Oil-based convection heaters take a while to heat up, but their surface temperatures stay much lower.

Radiative Heaters: Radiative heaters operate like a halogen light bulb but give off heat in the infrared spectrum. This means that instead of heating the air in a room, it can heat the objects around it. These heaters are very efficient since they heat objects directly, but often, they do not look as attractive as convection heaters [2].

Electric Space Heaters: There are a wide array of electrically powered space heaters available. These machines simply plug into any standard electrical outlet, making them ideal to use in the home. These heaters come in several sizes, styles and output levels.

Gas Space Heaters: These heaters are powered by gas, usually propane or butane. Because this type of power produces carbon dioxide, it can be dangerous to use these heaters in poorly ventilated areas [3]. Instead, they’re best used outside in work areas or on back porches. In this environment, they are superior to electric variants since you can easily move them from place to place. They also give off more heat [4].

Frequently Asked Questions About Space Heaters For Large Rooms

The watts needed to heat an entire room will ultimately depend on the size of the space. Generally speaking, a whole room heater will take roughly 10 watts of heating power per square foot of an area to heat it [5].

Ceramic space heaters are convection heaters and are incredibly efficient because they run on electricity. They don’t release carbon monoxide or other toxic emissions [6]. They also use less electricity than different types of space heaters. 

Space heaters are designed to use for shorter periods as they are not meant to substitute the central heating in your home. It’s also important to note that these heaters can pose electrical and fire hazards if left on too long. 

According to the Department of Energy, the U.S. Consumer Product Safety Commission projects that 25,000 residential fires are associated with space heaters each year [7]. You should be turning off your heater and not letting it run overnight. The good news is that many of these heaters have timers to shut off automatically.

Since infrared heat is comparable to the sun’s heat, many think infrared heaters are bad for a person’s health. The reality is that infrared radiation does not have adverse health effects like x-radiation and microwaves do.

In Conclusion: Space Heaters For Large Rooms

Whether you live in a warm or cold climate, space heaters are a great way to heat the large rooms in your home. The vast range of sizes, styles, and power levels ensures there is a perfect heater for everyone.
