What to Consider When Choosing the Best Energy Efficient Space Heater

Now that you have checked some of the best energy-efficient space heaters on the market today, it’s time to learn how to choose the best heater for your home or office. We highly recommend that you begin by assessing your needs and matching them with the following features:


When choosing a space heater, the first factor you need to consider is how the heater produces heat. Most space heaters use convection to heat and maintain warm air. You can choose oil-filled, ceramic, micathermic or infrared space heaters. Infrared heaters are most popular, but micathermic and ceramic are also becoming popular in the market. Let your seller know your needs and explain how each type will benefit your home before making a purchase.

Safety Features

Some space heaters become hot and may heat the floor, walls, and other items close by. That means they can be dangerous if left unattended for a significant amount of time. If you have children or pets, you might want to invest in a space heater that is cool to touch to prevent accidents. There should be overload protection to protect against overheating and tip-over protection to turn off the heater once it’s knocked over. Be sure to check for the Underwriters Laboratory sticker that shows that the heater meets the current US Department of Energy safety space heaters.

House Size

The more space, the bigger the space heater. For instance, if you’re heating a 100-square foot room, you need a space heater with over 1000-watts. Study rooms and office spaces can use 200 or 400 watts.

Energy Efficiency

Your space heater should help you save a substantial amount of money on power. An excellent energy-efficient heater should have multiple energy-saving features, such as a thermostat to regulate heat based on the ambient environment to avoid wasting energy. They should come with specific settings to automatically turn off after the pre-set period. Some space heaters can be controlled via WIFI, which allows you to turn on the heater to heat the house before you return from work or school.

Noise Level

Space heaters can be loud. Therefore, it’s necessary that you pay attention to the level of noise the heater produces to avoid distractions or noise pollution. This is particularly important if you have a patient or elderly person living in your house. If noise is a concern for you, avoid space heaters that use fans as they can be particularly loud and go for infrared space heaters that produce little or no noise.

It depends on how you use your heater. It’s essential that you get the right size of space heater to avoid overheating your house and check for UL or ETL listings that certify efficiency and safety.

To get the most out of your space heater, you can mount it on a wall or position it in a corner with no obstruction to heat the entire room.
