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. If you want to enjoy winter as a couch potato, you’ll want to look for this feature in the heater you purchase.

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 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.

Care Level: Since all heaters operate differently, they may require distinct care methods. Think about how much time you have to maintain a heater before deciding on one. If you’re a little forgetful, it might be best to purchase a heater with automatic shut off features.

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].

Overcoming Heating Struggles

When you’re on a mission to find a suitable space heater for a large room, the struggle to make sure you don’t make any mistakes is real. Lucky for you, our guide will tell you everything you need to know before you go ahead and splurge on something you’ll never use.

There are some things you should consider when buying a space heater, including your usage and budget. If you only need a heater when you’re in a room with low heat for an hour or two, it doesn’t make sense to spend a fortune. But, if you plan to spend a large amount of your time in a low heat room, you might need to give yourself a space heater for Christmas. There’s no feeling like sitting in the warmth of your home without a worry about how to keep your body from freezing!

There are many benefits of having a space heater, including the cost you save from letting the central heating system do all the work.

On the contrary, if you’re looking for a heater for a small room, you might not have to do as much digging to come across the right product. Read some of the best small space heaters review to make your decision process smoother.

Heating Other Types of Rooms


A space heater is particularly helpful when you work from home. Think about which room you’ll be working in when choosing a space heater for your office to ensure that the heater is efficient. The last thing you want is to call in sick and tell your boss you can’t work because your room is too old. That’s not going to get you the employee of the month reward!


Doesn’t matter where you are, the need for heat doesn’t end! Whether you’re working at the barn or trying to keep the animals safe, you need to find one of the best space heaters for your barn before making a purchase.


The last thing you want is to run out of the bathroom shivering in the winter. You may need to find a heater that covers small areas to keep your bathroom cozy. Make sure you don’t place the heater near water to avoid hazards. Since the bathroom is a small area compared to the rest of your home, the air quality might be a concern. You can use some products to improve your home air quality by starting from the bathroom.

Baby Room:

As a parent, you probably spend most of your time worrying about your child’s safety. When winter approaches, you’d want to make sure your baby is cozy at all times. You want to enhance space heater safety in your baby’s room before you make a purchase. Luckily, some heaters offer multiple safety measures to ensure your mind is at peace as your child sleeps in the comfort of a heated room.

How To Heat A Large Room With High Ceilings

Even if you have a functioning heating system, when you’re in a room with high ceilings, the heater might be underperforming. If you’ve settled for a cold room where you have to tippy toe until you run to your room that has a warm blanket, it might be time to make some changes. You deserve a home where you don’t have to shiver every time your foot gets out of the blanket.

Luckily, your only option isn’t to spend the entire winter wondering when warm weather will kick in and give you relief.

The Best Ceiling Fan Direction

Using a ceiling fan in the winter when you’re already suffering in the cold might be counterproductive. However, ceiling fans can help manage the interior climate in the winter. Even if you’ve got a great space heater for your room, the ceiling fan direction might impact the air circulation.

When you’ve got your fan on, you’re probably not too focused on the direction it’s in, as long as it’s working efficiently. But, the trick to ensuring its maximum potential is by switching it to the right direction. Ceiling fan direction should be clockwise in the winter and running at the lowest speed. The fan pulls cool air closer to the ceiling, displacing the warm air trapped on the top of the room, creating a warmer environment.

Purchase A Space Heater

If you’re having trouble with finding the right temperature to keep you warm, it might be time to invest in one of the heaters listed above. You need to stop overrunning your central heating system to save the costs you’ve been bearing. The best electric space heater for a large room will ensure that you don’t have to stress over unnecessary expenses throughout winter.

Partially Shut Unused Vents

Sometimes, the best type of space heater for a large room can’t do its job if there are partially used vents draining your heater’s energy and slowing down the heat process. Before choosing a space heater for your office make sure you go around your home and close any vent you don’t use. If a vent is open and unable to circulate air, you’re better off shutting it down.

Use Natural Sunlight

Even if you have the best space heater for a large drafty room, a dark area might take away its benefits. Open your curtains and blinds, allowing natural sunlight to come into your home. While you utilize the golden hour to take a few cute selfies, the natural sunlight will do its job and warm up your space.

In addition to sunlight, look into the Dyson Pure Hot + Cool HP04 Air Purifier, Heater + Fan for a complete home temperature and air quality makeover. You can remove allergens, unpleasant odours, cool down, or heat up the room through a single product. Sounds like a win-win!

Which Room Heater is Best for Big Rooms?

Finding the right heater for a big room is one of the key factors contributing to a cozy winter. The last thing you want is for your heater to work on half of your room while you’re shivering on the other side. Luckily, there are some heaters created to work efficiently in larger spaces. The Dr Infrared Heater Portable Space Heater generates more heat than most models, allowing you to enjoy the warmth in the comfort of your bedroom. Since this space heater puts out the most heat, it can be a great addition to your bedroom or living room.

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]. Since one watt of electricity produces 3.4 BTUs of heat, 10 watts of power equates to 34 BTUs of heat output for each square foot of room area. In simple terms, the watts required to heat a room depends on the size and shape of the room.

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. Since the outside plate of a ceramic heater stays cool, they are safe to leave on overnight as well. So, if you’ve got a ceramic heater running in the back, you don’t have to worry about it being unsafe.

How to Find the Right Size Heater?

When determining how big a room a 1500w heater will heat, it is essential to do the measurements and figure out the size of the space you want to heat. When you’re figuring out how big of a space a heater can cover, you need to consider the heater wattage output. You will need approximately 10 watts of heating power for every square foot of floor area in the room. So, a 1,500-watt heater can cover up to 150 square feet. So, you need to measure your space before finding a heater and choose the wattage output that can efficiently cover the entire area.

What Does a 1500W Heater Mean?

If you’re not familiar with the terms used to describe the features of a heater, it can be challenging to make a final purchase decision. When heaters mention they are 1500w, they indicate that a 1500W space heater uses 1.5 kilowatts of electricity per hour or 1.5 kWh. 

Do All 1500W Heaters Heat the Same?

You may notice a variety of heaters with 1500w. Sometimes, the wattage output might be the deciding factor among multiple products. Since the top brands create products with safety and efficiency in mind, many 1500w heaters will provide similar heat. However, it is essential to consider other factors such as the size, portability, and safety features when deciding which heater to purchase. Two different products with 1500w may provide similar heat, but one could be significantly better than the other.

What is the Cost of Running a 1500W heater for 24 Hours?

Running a heater for 24 hours may not be the ideal thing to do as it would consume a lot of energy, raising your electricity bill. It can also be a health hazard if the heater tips over. Fortunately, many heaters come with several safety features to ensure that the heater automatically shuts off if you forget to turn it off. 

If you live in a frigid space and a space heater is your only saviour, you may need to run the heater for 24 hours. When you use the heater for long hours, give it some break in between to cool down. 

The cost of running a 1500w heater for 24 hours can vary based on your location, but you can use a general equation to calculate the estimated running cost of electric heaters:

Heating Running Cost (per hour) = Power (W) * Price Of Electricity ($ per kWh) / 1,000

The running cost of all the electric space heaters depends on heater wattage and the price of electricity in your area. To determine the exact cost of running a 1500w heater in your home, find the price of electricity per kilowatt-hour in your area. Then, use the equation above for an estimate.

What Size Room Will a 2000W Heater Heat?

To calculate the correct wattage for a space heater, you need to measure your room’s length and width to determine the square footage. You can use a BTU calculator to estimate the heating needs of a typical room or house. The British thermal unit (BTU) measures the heat content of fuels or energy sources. 

A 2000W heater can generally heat a room between 180-240 square feet, although the right level depends on your specific room, ceiling height, and other factors. Since a 2000-watt heater is powerful, it is an efficient choice for large rooms.

Do Space Heaters Use a Lot of Electricity?

The first question that pops into many minds during a space heater purchase is its energy consumption. The fear of a high electricity bill steers many people away from space heaters, leaving them with a cold home and layers of blankets to feel warm. 

The reality is that whether or not space heaters increase the electric bill depends on the type of heater you purchase. Some space heaters, despite their size, use a lot of energy and can spike your bill. However, some might be more energy-efficient than a central heating system.

However, you can control your electric bill by being mindful of how much and how often you use your space heater. Many heaters come with an auto shut-off option, but if you keep an eye on the heater and make it a habit to turn it off when you don’t need it, you will save some costs. 

Is Infrared Heater Better Than Electric?

Infrared and electric heaters both come with their pros and cons. If your biggest concern is energy efficiency, infrared heaters are suitable. Infrared heaters are cheaper to run, more silent, and the heat lasts long even if you’re heating a space where you have to open the door, letting cool air come inside constantly. However, it can be challenging to control the temperature, and the surface can be hot when running on high power. If you have children or pets who can reach the heaters and you cannot place them on walls or out of reach of them, you may want to avoid infrared heaters.

On the contrary, electric heaters come with a heavier price tag in energy efficiency, but the products themselves can be cheaper since they are mass manufactured. They also come with more options and are safer for a home with kids and pets since they aren’t overly hot to the touch. But, electric heaters can lose heat quickly as they rely on spreading heat through the air. So, if you do have to open the door or windows constantly, you will lose the heat quickly, and it may take time to warm up the room again.

Choosing between an infrared and electric heater will be easier when you think about the type of room you will place the heater in, the people that live in the home, and your expectations from the heater.

What Happens if You Plug a Space Heater Into An Extension Cord?

Plugging a space heater into an extension cord can overheat the space heater and be harmful to your home and the people in the room. According to The Electrical Safety Foundation International (ESFI), plugging a space heater into a power strip can cause a fire. Avoid plugging a space heater into a power strip and plug them directly into a wall outlet for your safety. Wall outlets can handle a higher wattage, and since heaters take up a lot of power, it can be unsafe to use an extension cord.

Extension cords can also lower the heater’s efficiency and leave you with an unexpectedly high electric bill. When you plug a heater into an extension cord, the power supply has to increase its power to reach the space heater, which puts pressure on it and leads to unnecessary costs.
