How To Choose The Most Efficient Electric Heater
There are many factors that can affect your space heater’s electricity consumption.
The size of your room
There is no need to go for a big-sized space heater when your room is under 300 square feet. Usually, a fan-forced or a micathermic panel space heater is designed for small to medium rooms while a oil-filled or an infrared heater is capable of heating a larger area. So depending on the size of your room, you can opt for a suitable type of heater to optimize its performance and save your energy bill from surging.
Energy Efficiency Features
Look for an electric space heater that has at least one of the features we mention below.
Multiple heating setting feature can save you a lot of money. When you don’t want your room to be too hot, you can set your heater at the lowest setting or adjust it to your desired temperature.
Some space heaters also come with eco/ energy saving mode which switches back and forth between low and high settings to maintain your desired temperature.
For example, a space heater has 750W & 1500W settings, you set the heater thermostat to 72°F and turn on the eco mode. The space heater will use 1500W to warm the room to 72°F, then switch to 750W setting to maintain the temperature, when the temperature drops, it will automatically switch back to 1500W.
Also look for a heater that has a timer function. If you often forget to turn off your space heater or wake up in the middle of the night because of the overheated room, this function is a perfect solution for you.
An adjustable thermostat coming with the space heater can keep your bill from skyrocketing. Simply crack down the thermostat a few degrees and you can save as much as 3% for each degree you sacrifice.
Space heaters may look small but they are really dangerous. According to the National Fire Protection Association, space heaters are responsible for one third of winter house fire and more than 80% of the winter heating fire deaths. So it is be wise and safe to choose a space heater that has tip-over safety switch and overheat protection. They help automatically turn off the space heater when it falls on the ground or when overheating is detected.
Moreover, you can opt for some model that have seal of nationally recognized testing laboratory such as ETL (Edison Testing Laboratories) or UL (Underwriter Laboratories).

How much does it cost to run a 1500 watt heater for a month?
The wattage (power) of a 1500 Watt heater is 1500 Watts (quite obvious), also written 1.5 kiloWatt (kW). (1,000 Watt = 1 kiloWatt) Let’s assume the heater is actually heating 8 hours a day. So, for a 30 days month, the heater will be running 30x8=240 hours.Then, the average electricity rate in the US in August 2019 is of 13.19 cents per kWh consumed, which is 0.1319 $/kWh.
The formula to calculate the cost is : power x duration x electricity pricing. The units have to be the same. We will use dollars, kWh, kW and hours. So, our formula becomes: power (in kW) x duration (hours/month) x electricity pricing (kWh) = monthly cost ($/month)
1.5 x 240 x 0.1319 = 47.5 $/month
To conclude, a space heater running 8 hours a day will monthly cost you $47.5.
Contact us if you require help for this calculation. Note that, it’s theoretical. You might not be using the whole wattage of the heater or using less… Anyway, you now know how to calculate.
Are oil filled heaters more efficient?
Even though oil filled heaters are sometimes called ‘radiators’ because of the fact that they look and heat like steam and hot water radiators, they actually heat by convection. Since they operate at relatively low temperature, they give off a pretty small amount of heat by infrared radiation. They also take time to heat up, but take time to cool down (hence providing heat for a while after turning them off).
Consequently, oil filled heaters are a wise choice to heat rooms entirely. However, they will not not warm you up until the entire room is warmed up - they warm you up by making the room warmer. Infrared heaters, on the other hand, heat by infrared radiation. This makes them a nice choice when you want to warm people quickly despite the surrounding air might still be cold. Infrared heaters are also a good choice in areas that cannot really be heated. Therefore, they are a solution for garages, workshops, or even outdoors.
To conclude, consider what you want to do with your heater. To warm rooms, go for an oil filled heater. To warm people in cold areas which cannot easily be heated, choose a infrared heater.
Which is more efficient space heater or central heat?
The answer depends on how large of the area you want to warm up. In general, electric space heaters are more cost-effective when they are used to heat one or two rooms/areas or to supplement inadequate heating in one room.
However, when it comes to heating larger areas or every corner of the house, gas furnaces only cost 43% of the total cost of using a space heater to warm up the same area.
How do you make your home more heat efficient?
Insulate your attic and walls
This DIY project may take you the whole weekend and yet it adds up a significant amount to your savings every year. According to the Department of Energy, a properly insulated attic can cut down 10-15% on your electricity bills, whether you are using a central heating system or a space heater. The maps and the table below show how much of insulation you should add to your home according to the particular region you are living in.
Upgrade or replace windows
If your windows are old and leaky, it’s high time to replace them with more energy-efficient models or add weather-stripping to boast their efficiency. If you go for the first option, in many areas, the cost of Energy Star-rated replacement windows is reasonable, about $15 each, which is initial cost-effective and profitable in the long-term too.
Install insulated curtains and blinds
Curtains and blinds will definitely reduce the heat loss from your windows by up to 25%, prevent chilly drafts getting your cozy home and dampen sound too.
Plant shade trees and shrubs around your house
Here is a good news for any landscapers and gardeners. A properly designed landscape can increase your home’s energy efficiency and reduce air pollution. It can also cut down your heating and cooling bills up to 40%.
Plant some large deciduous trees on the south and west-facing sides of your home. They can block the radiant heat from the sun that overheat your home in the summer and let the sun shine through your home in the winter when the leaves are gone. Also plant evergreen trees and shrubs to the north and northwest of the home to provide your home natural windbreak that prevents the winter from stealing heat away.
Clean your space heater
Dust generated by the fan or the fins can make your space heater less efficient. make sure that you clean it regularly and at the same time, check if there is any problem and have it repaired by a qualified expert as soon as possible to prevent any unfortunate accident.
Lower the thermostat
You can save as much as 3% on your heating bills for every degree you crack down the thermostat. You can easily save money by setting the thermostat at 68 degrees when you’re awake and setting it lower when you’re asleep or away.
When you return home, the first thing you probably feel is the cold inside your home. However, don’t just turn the thermostat all the way up to 75 degrees, it won’t warm your home quicker. Instead, set the thermostat back to 68 degrees, and put on some clothes, socks or blanket.
How about putting on more warm clothes instead of increase your heater setting? It definitely saves you a lot of money.
Heating can be costly if you don’t insulate your home properly and without a energy-efficient space heater. We hope that with our buying guide and list of most efficient electric heaters, you will have a warm and toasty winter without worrying about paying the bills at the end of each month.
