Features to Consider When Buying A Energy Efficient Space Heater

Energy-saving heaters are suitable when used close to a lounge chair or underneath a desk. The space heater you intend to go for should suit the room size or have the capacity to produce and distribute heat that will circulate the entire room evenly. Below we shared some of the basics you need to look out for before making a purchase.

Your Heating Needs

The rule of thumb is to go for space heaters designed to produce 10 watts of energy power on each square foot.

For example, if the space you intend to use the heater on is a 100-foot by 12-foot room, then you will need a 1200-watt space heater. The larger the room you intend to heat, the stronger the heater recommended.

Other considerable factors that may influence a heater’s performance include the number of windows, the nature of the wall, the height of the ceiling, and the number of furniture. 


Of course, safety should be your ultimate priority, especially for homes with kids and pets. Stats has it that over 25,000 American homes are exposed to fire outbreaks caused by space heaters each year.

So, it’s smart to go for a space heater with an additional safety layer to reduce potential risk. Most brands are built with an extra safety layer to play once the heater unit gets overheats or knocked over.

Additionally, there are space heaters with exterior cases designed to secure and keep the units cool. Some of these models have motion sensors that automatically turn off the heater once a kid or pet comes close.

Energy Efficiency 

One of the most important features to look out for before buying a heater is efficiency. The fact is no one wants to rack energy bills. Unlike most heating appliances, a space heater is not tested by the Environmental Protection Agency (EPA) nor rated by Energy Star; these are among the major reasons why the device is recommended to supply heat energy with less power consumption.

Noise Level 

Comfort goes a long way too! Most space heaters are designed to run with less noise; however, if you go for space heaters that use oil emit or infrared, they emit zero noise, unlike most conventional space heaters that come with fans and emit noise when used indoors. 

Also, you can check best kerosene heaters to heat your home in winter.

How to Stay Safe When Using an Energy-efficient Electric Space Heater?

1. Position Heaters on the Right spot

Place the space heater in the right position, ensure it on a sturdy and flat surface three feet from upholstery, bedding, furniture, rugs, or anything flammable. Avoid using heaters on high-traffic areas like doorways; this will help reduce the risk of getting your child or pet burnt.

2. Plug on a Powered Outlet

Plug the heater directly on an electrical outlet with enough capacity to power the device. Avoid using an extension cord; this can lead to overheating, electric shock, and fire.

3. Regular Maintenance and Inspection

Regular maintenance and inspection are required occasionally; clean and maintain the device to ensure it is working properly. Once it shut down, unplug it and allow its parts to cool off. Use a cloth to wipe off the exterior to remove dust and allergens that are likely to disperse in the room.

4. Turn Off and Unplug

It is important to turn off the space heater and remove it from its plug. However, some models come with a self-timer program that automatically turns off it once you are away.

Tips for maintaining a Space Heater

Heater, when used rightly, can be of great benefit to the entire family, but the reverse is true when handled with less care. Below, we shared some effective tips on how to maintain a space heater.

Don’t leave Heaters Running Alone

Most space heaters are designed to be self-operated, but one of the best ways to prevent fire outbreaks is to check out the performance when the heater is running. Ensure your pet and kids are three feet away from the device; this will help prevent them from accidents.

Avoid Flammable Objects

Observe the “three-foot rule.” Avoid placing flammable objects close to the heater; this can take the form of bedding, furniture, papers, paint, matches, curtains, and other objects.

Keep It Away From Water

Water blending with electricity is extremely dangerous. So it’s advisable to keep space heaters away from bathrooms and kitchens.

Always on the Floor/Wall

Except you’re lying on the floor; avoid placing heaters in different positions aside from the floor. Avoid placing it on a stool, shelf, or bench made from wood. Placing the device on these surfaces increases the risk of the heater tipping over, which can most times lead to a fire outbreak.

Energy Efficient Space Heaters vs. Normal Space Heaters

The answer here relatively depends on the size of the room you intend to heat. If you want to heat one or two rooms, space heaters will be more economical than a central heater. However, if you want to heat the entire room, we suggest going for a conventional heater recommended by the United States Department of Energy.
