Since you’re relying on this ceramic heater to help keep your large room livable, you definitely want to make sure that the product at which you are looking actually works. While all of the different electric heaters on this list work incredibly well, this space heater for large rooms really feels like a lot of extra effort was put in to make sure that it keeps running in a way that will not only heat up your room but that won’t interrupt your life. 

The electric heater unit, like so many other electric heaters, starts with the heating element. Able to reach a warm temperature in only a few moments, it gets to the hard work of heating up large rooms without requiring you to leave it on for a long time. You can actually set the heat on this one for one of three different options, allowing you to determine exactly how you’d like your room to be and to change things around during the day.

TaoTronics PTC 1500W Fast Quiet Heating Ceramic Tower Heater

Fast and quiet. Those are two of the large terms that get thrown around when talking about large room space heaters and they’re honestly both quite important. You want a space heater that gets up to maximum heat quickly so that you can start using it as soon as possible, but you don’t want that speed to come at the expense of your hearing. That’s why a heater like this ceramic heater from TaoTronics is so popular – it manages to be both quick and quiet at the same time. 

The first selling point of this unit is the quick heating capacity. It takes less than three seconds to reach seventy degrees so users can start experiencing the warmth they need to work or relax in mere seconds. The is actually designed with precision heat in mind as well – you can set it to one of three different temperatures so that your room reaches the perfect heat at the time that makes the most sense to you.

A remote control is a convenience that is often overlooked. This is really one of the more user-friendly models on the market as well as one of the more reliable large room heaters. 

Comfort Zone Oscillating Space Heater

One of the most common complaints about space heaters is that they’re really only good for heating up a specific space. Even those that are meant for larger rooms often seem to only really deal with a cone of space that is in front of the unit, allowing users to feel warm only if they are in a very specific area. Fortunately, oscillating heaters have helped to solve that problem by moving the heating element around enough to better distribute heat. One of the better heaters that rely on oscillation is this unit from Comfort Zone. 

Oscillation is one of those simple mechanical movements that you think would’ve become common in space heaters years ago. Just like a fan helps to move cooler air around a room by moving from side to side, so too does this space heater help to distribute the warm air with the same pattern of motion. What this means for the average space heater user is that the heat is going to be better distributed throughout the entire room, making the device something that can be used to keep more than one person in the room warm at a time. 

Oscillation isn’t the only feature here, though. The unit does a great job of heating up the large room such as a living room quickly, both through the use of a relatively high-powered element and the aforementioned oscillation. It also features an eight-hour timer so users can turn the element on during the beginning of a workday and still not have to worry about turning the unit off when they leave at night. This little extra safety feature can mean quite a bit, especially if you’re the type who has avoided space heaters because of fire-related fears. 

PELONIS PH-19J 1500W Fast Heating Tower Heater

Safety is a really big deal when it comes to space heaters for a large room. If you’ve ever met anyone who has used an older model, you’ve probably noticed how careful they are to make sure that the unit is turned off whenever it is not in use and that it is kept far away from anything that is flammable. Even then, those heaters can still feel like they’re a danger to use for anything other than short stretches. Thankfully, modern space heaters are a lot safer than those made in years past. If you’re looking for a safe and reliable heater, you’ll want to look at this compact unit from Pelonis.

This heater attacks the problem of safety from a few different angles. On one hand, it has features that are transparently there to solve old problems – the unit automatically shuts off if it gets too hot and the unit will turn off if it gets tipped over. While both of these features are really solid, there are also other features that do a lot to solve old problems in new ways. As an example, the unit hits its maximum heat quickly, which means that it’s much harder to leave on for too long and then forget about it. 

The good news is that while this unit focuses strongly on safety, it also manages to put a lot of focus on being useful. The fact that it reaches a reasonable temperature quickly isn’t just a safety feature, but one that’s going to let you use your large room more quickly. At the same time, this unit also manages to be quite compact while still putting out a lot of heat, allowing you to place it almost anywhere. If you’re looking for an efficient unit that’s safe to use, this one is a great choice.

Heat Storm HS-1500-PHX-WIFI Infrared Heater

Let’s talk bells and whistles for just a moment. While those aren’t usually the selling points for something like a space heater, there’s something to be said for having any kind of tool that’s on the cutting edge of modern design. Though it’s absolutely vital that your space heater actually serves the purpose for which it was designed, you can absolutely look for something that goes above and beyond.

You can even pick it up and go whenever you like, as the unit is designed to be portable. It’s easily one of the most convenient heaters on the market today. 

Aikoper Space Heater

Consistency is one of the keys to maintaining the level of comfort in a room. While having heat is good, it’s only useful if you can keep the room at the right temperature. If you experience wild fluctuations all throughout the day, you’re eventually going to need to make a change. Fortunately, this unit from Aikoper helps to solve the problem of inconsistency by providing a space heater that not only manages to keep the heat at a room level, but that’s very easy for users to adjust to their liking. This is one space heater that really makes a large room more comfortable. 

The big feature for most is the fact that this unit is easy to adjust to a consistent temperature. Unlike most space heaters that can only be adjusted to a general temperature, this unit allows users to set the temperature to the specific degree – and even better, the unit does its best to keep the room at that temperature. This means fewer giant fluctuations and more of a chance for the unit’s owner to stay comfortable. Though most are going to find it easy to set this unit to a single temperature and keep it there, it is nice to know that there are options. 

In addition to the consistent heat, the unit also provides for peace of mind through a number of safety features. Like most of the modern heaters on the market right now, it has an auto-shutoff function for overheat protection once it hits a certain temperature. The unit also has an eight-hour timer, which is just long enough for users to keep it on during the workday without having to worry about it staying on at night. If you’re looking for something safe and consistent, this might be the unit for you. 

TaoTronics Space Heater

Even heating really matters when you’re in a large room. The last thing anyone wants is to relegate someone to the one cold spot in a room, and those who have to move throughout the day usually dread having to move out of a tiny cocoon of heat. If you’re in the market for a space heater, it’s generally best to find one that can handle heating a large space evenly. TaoTronics has made an excellent space heater for large room applications that not only accomplishes that goal, but that does so in a way that doesn’t cut the corner on other features.

The even heating is what most people are going to love about this unit, especially since it’s one of the main features promoted by the designer. Consistent, evenly-distributed heat can be a major bonus if you are trying to heat a large office space but it’s also lovely to have if you are just trying to keep the main room of an apartment warm. This feels as close to central heating as you are going to get with this type of heater, a major bonus for anyone who has tried to rely on unreliable space heaters in the past. 

There’s more to this unit that consistency, though. It’s got the usual safety features, including those that shut the unit off when it gets too hot or when it gets tipped over. The unit also features a great timer that allows you to run it for precisely as long as needed without making your worry about turning it off later. If you are in the market for an excellent space heater that’s useful, consistent, and that actually warms up a large room well, you’ll definitely want to give this one a shot. Once you get used to consistent heat, it will be hard to go back to anything else. 

Lasko 751320 Ceramic Tower Space Heater

What does it mean when a space heater is meant to work in a large room for you? For some, it means that it’s going to be effective enough to put out heat farther than a single desk and that’s absolutely fine. For others, though, the goal is to heat a space in much the same way a central heater would. There are unfortunately not a lot of heaters that work well in rooms over two hundred square feet, with the exceptions being held to fairly high standards. Luckily, this unit from Lasko is legitimately able to heat spaces of up to three hundred square feet.

Three hundred square feet is a huge amount of space for anyone, yet this one tends to perform admirably even when the space is drafty.

Safe, efficient, and easy to use, this is one space heater that’s going to handle the vast majority of your needs without requiring much in exchange from you. 

De’Longhi Oil-Filled Radiator Space Heater

While the vast majority of space heaters are electric, there’s still a fair number that uses oil. These heaters tend to be much more energy-efficient than their counterparts but there’s also something of a reputation that surrounds them. What goes into making the best oil-filled heater?

Frequently Asked Questions

What type of space heater is best for large rooms?

The best space heaters for large spaces are those models specifically made for a large room. Though there are some great personal heaters out there and is always the option to go with something smaller, they aren’t going to do much for those who are looking for the best option to heat a large room. Instead, you’re going to want to make sure that you focus solely on those that are rated for big, open spaces. 

Beyond that, there are so many types of space heaters for large rooms that your personal preference is really going to come into play. There are oscillating heaters that work like hot-air fans, consoles that radiate heat, and even wall-mounted heaters that feel more like a radiator. Regardless of what you pick, though, one of these dedicated units will help to keep your large room a little bit warmer. 

How big of a room can a space heater heat?

Space heaters tend to heat up rooms of many different sizes. A personal space heater, for example, is probably only going to work in a space that’s around the size of a very small bedroom or even a cubicle. Larger space heaters, on the other hand, can do a very good job of heating up larger spaces. There are space heaters for large rooms on the market right now that can deal with spaces in excess of three hundred square feet, with even more than can comfortably work in spaces of up to two hundred square feet. As always, the amount of space that can be efficiently heated is going to come down to the individual model chosen as well as the construction of the room in which the device is situated. 

How do you heat a large open space?

Heating a large, open space is usually a matter of finding the right kind of space heater. While there are plenty of heaters on the market that are made for personal use, it’s best to look specifically for those models rated for a large room. Most of them will be advertised as large-room electric models, though there are a few high-end pieces that will only reveal the total square footage that they can heat when you look at the specifications sheets. As a rule, the best way to heat a large, open space is to ensure that you have a large space heater that is rated for a space that’s at least as big as the space in which you are operating. There are also those that are more aesthetically pleasing but still very effective such an LED electric fireplace

Which type of space heater is the most energy-efficient?

The most energy-efficient space heaters for large rooms are usually those that have some kind of energy-efficient mode and surely keep electricity costs down. While you can certainly look around for heaters that have an Energy Star sticker on them, it’s even better to take a look at the modes that are available on the heater for large room applications. It’s fairly common to find an ‘Eco’ mode in most modern units, modes that put out heat a little more slowly but that ultimately have much less of an impact on your electrical bills. 

Space Heater for Large Rooms Buying Guide

Let’s face it – you’ve probably not spent a lot of time looking at space heaters in your life. While it’s great to want to go to the store and to pick up something that just works, the truth is that you need to know a little bit more about the electric heaters before you should feel comfortable picking one up. Below are some of the most important factors at which you need to look when you’re trying to find the best space heater for your large room in your home or office. 

Usage

Before you even start to look at electric space heaters, you have to think about how and why you are going to use those heaters. Is your plan to heat up a large room or are you just worried about the area directly around the heater? Is this heater going to be the only source of heat in space or is it going to supplement another heating system? Do you have specific needs insofar as heating is concerned, or are you just looking for something that’s going to work in a general way?

If you can’t answer all of these questions, you can’t make the right choice. Usage is a huge factor because it’s going to play into all of the other factors discussed below. Try to think about exactly how, when, and where you are going to use your heater so that you can make an informed choice. Once you do that, all of the other pieces should fall into place fairly easily. 

Heat Output

This is the big one for most people who choose to buy electric heaters. When they’re looking for this kind of product, what they’re really looking for is something that will keep them warm and supplement their home heating system. Though the vast majority of space heaters have at least some kind of output, you’re looking for something that’s going to be able to effectively deal with a large space. Your goal isn’t just to find a space heater that can reach a specific temperature, but rather one that can deal with a specific room.

Large room space heaters tend to work best in spaces between one and three hundred square feet. It’s best to look at the individual product to figure out its exact range in order to determine whether or not it is a good fit for the room you’re looking to heat. Note that most of these heaters can deal with even larger rooms than what’s on the box, but the efficacy of the heater does drop beyond the stated range. Try to find something that’s going to at least hit the minimum space in which you live or work. 

Room Coverage

If the ability of an electric heater to heat up space and supplement a home heating system is the primary concern of most buyers, the secondary concern definitely has to be the unit’s ability to actually deliver that heat. If you’ve ever used on an old-fashioned space heater, you know that it’s never really a problem to get warm when you’re standing right in front of the heater – the real problems come when you’re more than a few feet away. When a device is advertised as being able to heat a large room, it usually does so in one of two ways.

The first major way is just through standard forced hot air. The unit will put out enough heat and air to disperse throughout a room, warming the whole area at the same time. The end result here is that the spaces nearest the heater and in front of the heater will get warm first, followed by the outlying areas. The other option is through oscillation. Like a fan, the heater will turn back and forth to push out the heated air. This gives a more even distribution of warm air throughout the room, albeit one that might not be quite as quick in the space directly in front of the heater. 

Controls

Controls do a lot for space heaters. Good controls tend to make a space heater safer, while many of the safety features of a space heater tend to be tied to the control scheme. The vast majority of space heaters use some kind of analog control scheme that will allow you to set a basic heat level and turn the unit on and off. There are, however, other units that allow you to do a little more. They might have digital thermostats that allow you to set a specific heat or remote controls that allow you to adjust the heat from afar. How the controls are set up will always have a huge impact on how you use the heater, so give this factor some thought. 

Safety

Space heaters don’t have the best reputation, largely due to old and cheap models that didn’t have the right safety features. Today’s space heater is an incredibly safe device but you can feel even safer by scouting out the features used to ensure that the units won’t start a fire. Try to make sure that your heater will automatically turn off if it gets too hot or if it falls over, for example, and you might feel safer if you find one that has a timer so it automatically shuts down. Even these small features can make a huge difference when it comes to your peace of mind. 

Add-ons and Extras

There are dozens of other features that can be found in space heaters, ranging from the obvious practical to tiny technological marvels. When you see an extra feature in a space heater, try to stop and think about whether you’ll actually use it in case you are on a fence with it as opposed to a permanent installation. If so, it might be worth considering if the other factors discussed above are sufficiently met. If not, the extra features will end up nothing as fun novelties on a device that you probably won’t ever use.
