Best Space Heater for Large Room

If you live in a cold climate, getting a space heater might be a really good idea because these devices combine portability and efficiency to provide a very interesting alternative to central heating. Of course, they are not going to completely replace your whole-house heating, but they can help you heat up a large space without breaking the bank and you can move them all over the place without being attached to a certain spot. Because of that, space heaters may fit into the interior of your living room much better than an immobile central heating radiator with its bland white look.

If you don’t frequently use central heating in your home, space heaters may be an altogether better solution because they don’t require as much maintenance as central heating. And since you can move a space heater from the living room to the bedroom in the evening and from the bedroom to the kitchen in the morning, your heating system is going to be a lot more flexible and likely save you some money in the long run.

General Space Heater Information  

If you’re not very familiar with the devices and systems that bring heating and other utilities to your home, you may not really know what space heaters are. This is why we have decided to start off our review with an explanation of what space heaters are and how they work. If you’re already familiar with that information, feel free to skip this section and continue your search of the best space heater for a large room with the help of actual product reviews below.

The Purpose of a Space Heater  

Obviously, space heaters are meant to provide heating. They are normally used to supplement whole-house heating systems in cold climates, to heat up small spaces that are not suitable for central heating, or even to provide some warmth outside (provided there’s a power outlet available).

Different Types of Space Heaters

All space heaters more or less share the same mechanism of action (more on that below), but they use different heating elements to provide their effects. The most popular space heater types are convection ones (rely on wire elements to provide the heat) and infrared ones (emit radiative heat). There are also micathermic, electric, and oil space heaters, but these are less common and might be harder to find depending on where you live.

How Do Space Heaters Work?  

Different types of space heaters rely on different mechanisms to provide their effects, so we’re only going to take a quick look at the two most popular types. Convection space heaters use wire elements to produce heat and fans to distribute it, as wire elements are unable to pass the heat directly into the air. Infrared space heaters don’t warm up the air around them either; they emit radiation that is absorbed by the people, animals, and objects in their vicinity.

Now that you’re more familiar with space heaters, it is time to find the answer to your “best space heater for large room” question!

Tips and Hacks

Tip #1

Unless you clearly need to resort to a space heater as a main heating system, it is always a good idea to use it to complement your whole-house heating. Otherwise you risk overloading the space heaters which would lead to auto shutdown in most models. In addition, running space heaters is quite costly, so don’t count on them as the main source of heat in your home.

Tip #2

Go for a space heater model that imitates a fireplace to add that extra bit of charm to your house or even apartment. You don’t need to worry about having open fire in your home or paying high fireplace maintenance costs, just plug your space heater in and enjoy.

Tip #3

When choosing the best electric space heater for your large room, try to go for models that offer additional features such as auto shutdown and a programmable timer. You will not only get a much more comfortable user experience, but also feel safer using a space heater that will automatically shut down even if you forget to turn it off.

Space Heater FAQ

How much electricity does a space heater use?

Most space heaters use around 1500 Watts of power every hour. This means that if you have a typical space heater and use it for around 4 hours every day, it will end up consuming around 180 kWh per month.

How much does it cost to run a space heater?

While a space heater is often a relatively inexpensive purchase, it will accumulate costs as you use it. Using an average space heater for around four hours a day will result in additional $20 in your monthly electricity bill. This is why we recommend that you get a space heater model with a power preservation mode that will help you save some dollars every month.

How much does a space heater cost?

Most space heaters will only set you back a hundred dollars or even less, but you have to take into account the future costs that will inevitably come up once you start using the device. Depending on your use scenario, you can expect to factor in another 10 to 50 dollars for every month of using your space heater.

What is the best space heater type?

If you’re trying to figure out what the best type of space heater for a large room is, we can save you the trouble by telling you this: there’s no “best” or “ideal” space heater that is a foolproof solution for everyone. To find out which space heater type would be the best for you, you need to know the following things:

  • how often will you be using the heater
  • how big is the to-be-heated room
  • how fast do you need the heater to warm the room

Once you know enough about your future space heater use scenario, it should be easy to see which type of space heater would work best for you.

How hot can a space heater get?

Depending on the type of your space heater, it can always be cold to the touch or get pretty hot after working for a few hours. Of course, space heaters are designed to not get too hot on the outside so that they wouldn’t cause injuries and fires, but we still advise you to get a model with an auto shutdown feature so that the heater never gets hot enough to cause trouble.


Space heaters can be really helpful when you need a versatile, portable source of heat for your home, office, or garage. In cold climates, they can be used to supplement the main heating system, while in milder ones they can be used on their own to provide warmth during evenings and nights.

Whatever your space heater needs and preferences are, we hope that our review has helped you choose the best space heater for large rooms that is going to meet all your expectations and keep you warm and cozy!
