The Best Electric Heater for Large Room – Comparisons and Reviews

When the weather gets cold, finding energy-efficient and effective heating methods can be challenging, especially when you want to warm a larger-sized room. Whether it’s your large bedroom, living room, or even your office, you want to create a warmth that’s evenly spread and maintainable.

Electric heaters are a good alternative to central heating for heating large rooms. You can isolate one room at a time for cost efficiency, and focus on creating the warm environment you want in the room where you’ll be at a specific time.

But not any electric heater will do for a large room. To find the best electric heater for a large room, you need to search for heaters that offer some of the following features:

Quick Look

Infrared Heating

One of the most effective features to search for when you want to heat a large room is infrared heating technology. Many electric heaters work by producing warm air that mixes with the room’s current air to raise the temperature. This is generally effective, but may not always work evenly or strongly enough for a larger room.

Infrared heating works by warming the objects and people in your large room. By working this way, warmth is spread evenly throughout the whole room, and can be maintained more evenly.

Another good reason to use infrared heaters is that they do not dry out the air like many other electric heaters. The humidity in your large room will not be affected when using infrared heating, so you can avoid unnecessary discomfort.

Oil-Filled Radiator

If you want to explore other options besides infrared heating, oil-filled radiator heaters are another good choice. Many of these heaters are sealed with permanent oil that does not need to be refilled, making them very convenient.

Oil-filled radiators work well for heating up large rooms. Although they take longer to warm large spaces than some other types of heaters with fans, for example, the warmth they produce covers the whole room evenly without cold or hot spots.

You can even find many oil-filled radiator models that are thin and sleek enough that they won’t interfere with the decor of your large room.

Built-in Fan and Oscillation Option

Maybe you’re really set on sticking to a more classic type of electric heater for your large room. That’s fine, too. You will be able to find many heaters that will sufficiently heat larger rooms.

The features to search for when looking at more classic heaters are fan settings and an option for oscillation. These features will greatly contribute to the spreading of warm air throughout your large room faster and more evenly.

When you’re heating a large room with a standard electric heater, fan settings will allow the warm air that has been produced to be pushed throughout the whole room rather than only in the immediate area around the heater. Without fan settings, warm air will not spread far enough in a large room.

The oscillation option ensures that the warmth that is produced in your large room will be evenly spread. There’s nothing more annoying than using an electric heater in a large room and finding that you’re sitting in a cold spot because the heat hasn’t spread evenly!

Adjustable Thermostat

While you’re trying to heat a large room you want to be able to make it warm, not too cold and too hot. This is why it is helpful to find a heater that has an adjustable thermostat because it will afford you finer control over the temperature in your large room.

The great thing about many heaters with adjustable thermostats is that they have automatic control settings, which work in order to maintain the desired temperature in your large room once it has been met. They do this by automatically turning off and on, depending on what is necessary for the maintenance of warmth in your large room.

Remote Control

So you’ve turned your heater on in your large room and you go to sit down. Chances are that you might end up sitting somewhere far enough away from your heater that you need to stand up to adjust the settings. That does not sound convenient or pleasant, right?

I suggest that you invest in heaters that come with remote controls for your larger rooms. It is a simple luxury that will create a greater sense of relaxation in your everyday life. You don’t want to have to stand up any time you want to adjust temperature or turn your heater on and off!

Do yourself a favor and search for heaters with remote controls for your convenience.

Long Power Cord

If you are searching for a heater to use to heat a large room, then you also want to ensure that your heater will be positioned in a spot where it has the most convenient access for properly distributing air.

The situation of your electrical outlets is something that you won’t be able to change. But if you find a heater that has a long power cord, you are allowing yourself more options in where you place your heater. Perhaps your outlet is in a hidden corner of the large room. If you have a heater with a long power cord, you can situate your heater toward the center of the room.

Simply put, having a longer power cord grants you flexibility to better control aesthetic and functional placement of your heater.
