Editor’s Recommendation: Top Five Heater for 500 Square Feet

What to Look for Before You Buy?

There are different types of heaters, so it’s very important to consider your requirements as well as the features of the heaters themselves before buying. Here are some of the things that you should look for in your heater.

Type of Heater

The type of heater that you need might differ from another. There are convection heaters, conduction heaters, and radiant heaters. Each of them uses different methods of heating, and their efficiency also varies. So, you should go to one that you prefer to be the most useful.

Heater Capacity

The capacity of the heater is extremely important. You should find out exactly how many square feet the heater can cover before buying.

Naturally, a heater with the capability of covering 150 square feet won’t be able to cover a room of 500 square feet. Energy will be wasted if a machine with the ability to cover 1500 square feet is used to handle a room of 500 square feet. So, it’s essential to match the capacity with your needs.


You wouldn’t obviously want your heater to make your electric bills to skyrocket! So, when choosing an electric heater, make sure to choose an energy-efficient one. A lot of the heaters offer energy-saving modes. They’ll save a lot of your money for sure!


A heater increases the risk of fire hazards if not monitored properly. So, you have to be extra cautious in using them. Certain advanced safety features can reduce these risks greatly.
For example, some heaters always remain cool to the touch. The automatic power-off feature that powers the heater off when knocked over is another amazing feature. Overheat protection is probably the most useful one among them all. Make sure your heater has decent safety features before buying.
