Frequently Asked Questions (FAQ)

What is the best space heater for a large room?

A lot depends on your needs and your budget. Some heaters are meant to take care of an entire single floor while others to take care of one room. So, you’ll need to decide whether you’re looking for a heater to warm up your entire home, or just one specific room.

There are trade-offs regarding the size of the heater as well. A smaller heater may have fewer features, but it’ll cost less to use, so it may make sense to buy several smaller heaters than a single giant unit. However, there are a number of other factors to consider as well, such as noise, design, and safety features.

What are the best heaters to heat a room?

While there are many different kinds of heating elements, the most popular ones to heat entire rooms are fan convection heaters and stove-top heaters. They are both safer than other options, such as baseboards heaters, space heaters, and radiators. They are also more efficient and cost-effective than forced-air heating.

Fan convection heaters are very user-friendly. They use a fan to distribute the heat from one source and distribute it out to the room. They are typically used in one room, although there is an option to have them vent into another room. They are best for those with pets because they are safer than electric heating.

Stove-top fans are commonly used in open floor plans. They are attached to a stove and a fan blows the heat that is produced by the stove. The heat produced by the stove is then distributed out to the room.

Can a space heater heat a whole room?

Even though space heaters are primarily used as portable heat to escape cold, drafty rooms, there are a few true portable space heaters on the market which can heat large rooms. True space heaters use an internal fan to efficiently heat, circulate and distribute hot air into a room, whereas the majority of portable space heaters on the market simply radiate heat in all directions.

How do I make my large room warmer?

Before you do anything else, check vents and make sure they’re closed tightly. You don’t want your warm air supply going somewhere else! Next, turn off electronics like your TV, computer, and cable box. The more devices you have on, the more energy you’re using and the harder your thermostat has to work to keep your room at the temperature you’ve set. Keep lights dim to make it feel warmer. Don’t open a window. Too much cold air on a cold day will bring your temperature down faster. Turn your space heater on and aim it toward the coldest wall or corner in your room to warm it up and keep your heating costs lower.

Conclusion

A lot of different space heaters are available on the market for you to choose from, but if you're looking for the best kind of heater for you to use in the living room, then you can't go wrong with a forced air heater. They're able to do an excellent job of spreading heat to the entire room because they utilize a forced air system.

However, if you're looking for the best heater for a smaller or enclosed area, then you might want to consider using a radiant heater. These heaters use infrared or ceramic heat technology that can heat a smaller space without you having to move the heater around.
