Keeping your home warm in the winter can be tricky, I know. This is especially true if you have large and open rooms in your home, which can make it really difficult to heat. By investing in the best space heater for large room, you can easily keep your home warm without a ridiculous power bill.

Selecting the Best Space Heater for a Large Room

The most important thing to consider when you are shopping for a space heater for a large room is how many square feet a heater can easily heat up. You do not want to choose a heater that is designed for a smaller room, as these will really struggle to provide you with the heat that you need to be comfortable. It’s better to opt for a heater that is oversized, as you can easily turn it down.

Additionally, I recommend that you consider the safety features on the heater you think you may want to buy. While it’s easy to assume that your heater won’t ever be knocked over or covered up with a towel or blanket by accident, these things can happen, and can cause a fire.

When you opt for a heater that will automatically turn off if it tips over or overheats, then you won’t have to worry as much about the safety of your family and your home.

Additionally, consider if you want a heater that is attached to the wall or one that sits on the floor. Wall heaters have the benefit of being lifted off of the ground, but you can easily move a floor heater to a new space in your home.

Finally, think about if you want your heater to run on oil or only on electricity. While oil filled heaters take a little longer to heat up a space, they tend to stay warmer for longer, even when you have turned them off.

Benefits of having a Great Space Heater for a Large Room

Space heaters are great for heating up a certain area of your home without you having to turn on your whole-house heater. This is perfect for saving money on your heating bills and also allows you to selectively heat certain parts of your house.

They generally have very low maintenance and tend to cost a lot less than larger heaters do, which means that you can easily buy one for multiple areas in your home, if desired. Since they don’t require regular maintenance, they can be used for years without any worry over major parts breaking and requiring expensive repair.

Features to Look For

One feature that I love is a remote control. While not all space heaters have this great feature, it really does make it easier to control the temperature of your room without having to move. If you want to be able to adjust the temperature from your bed or sofa without moving, then this is a feature you will want to consider.

Another great feature to look for is oscillation. It can be tricky to find a space heater that will oscillate, but I think that it’s worth the search. When you buy an oscillating space heater, then you can rest easy knowing that it will do a great job heating up your entire space evenly.

How to Use Your New Space Heater for a Large Room

I think that one of the best ways that you can use your new space heater is to heat a specific room or area of your home, but seal off the rest of the house to keep it cooler. This allows you to focus the heat from your heater in a specific area.

I like to close the doors to my bedrooms or even hang a sheet to block the hallway so that we’re only heating the area of the house where we are spending time. This ensures that our space heats up evenly and that our heater works efficiently.


While space heaters are a great way to heat up your house, you have to be careful when using them so that you don’t put your family or your home in danger. You shouldn’t ever use your heater if there is a danger of overloading your circuits. Never use a power strip or an extension cord, as this can cause a major problem.

I also recommend that you check the cord on a regular basis to ensure that it is not frayed or damaged. If there is any sign of damage, then you won’t want to use your heater.

It’s never a good idea to use the space heater when you are away from your home. No matter how safe you think that your unit is, there can always be a problem when you are gone, and this can be disastrous.

Finally, keep all soft items away from the space heater and don’t let them touch the front. Any blankets, towels, or stuffed animals that are too close to the heater can be a real fire hazard.
