If you use a space heater in your home, please be aware that using a space heater can cause a significant increase in your monthly bill. A 1,000-watt space heater operating 12 hours a day will add about $40 to your monthly bill. If the cost does not deter you, remember how important it is to use space heaters safely.
One small space heater plugged in 8 hours a day can add about $50 to your monthly electric bill. Space heaters are a great way to increase the temperature in one room for a short period of time, but keep in mind that they can be costly to run and will result in a higher bill.
Savings using a space heater for 8 hours per day
Those with electric heat save less -- about $72 respectively -- and folks with natural gas, which is currently cheap, would pay about $36 more than if they ran a space heater.
It might be cheaper to heat one room with an electric heater. But it depends on the size of the room and how long you need to heat it for. Although gas costs about four times less than electricity per kWh, it will usually be heating more than one room through the central heating system.
Using a space heater 8 hours per day will use about 84 kilowatt-hours of electricity per week. It costs an average of $51.65 to run a space heater for a month and $258.26 to run for a year.
Most use 1,500 watts when on the highest heat setting, which costs about $2 per 8-hour day or over $50 a month based on the average cost of electricity nationally (local costs vary).
Space heaters usually consume between 400 and 1500 watts of electricity, and the majority use around 800-1000 watts. If an electric heater is used for 3 hours a day, then it could add up to 90 kWh of electricity to your monthly electricity bill, which could be an additional 5-10% of your total monthly electricity cost.
The amount of savings depends on various factors, including the heater's energy efficiency, the room size, and your local utility rates, but it can range from a few dollars to significant savings in colder months.
Oil-Filled Heaters
Oil-filled heaters use oil that's heated by electricity to create comfortable, radiant heat. Once the oil is heated, these can continue to provide warmth for a while, even after you turn them off, so they use less electricity overall.
Electric baseboard heaters are generally more energy-efficient for long-term use because they convert nearly all the electricity they use into heat and can be controlled to heat specific areas. Space heaters can consume more electricity, especially when used for prolonged periods.
What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
Con: Fire and Burn Risk
The National Fire Protection Association warns that space heaters account for more than 40% of all home heating-related fires. Space heaters are also responsible for most fire-related deaths during winter, and they account for thousands of burn-related injuries each year.
These higher costs may lead you to wonder about the most efficient way to heat your home. Many people debate whether it's better to use a space heater to warm individual rooms or rely on central heating with a thermostat. While both have benefits, central heat is generally a better choice.

Example (you can use an electric heater running cost calculator below for different wattages/kWh prices): If we assume the price of electricity is $0.1319 per kWh, a 1,500-watt electric space heater will cost; $0.20 to run per hour. $4.80 to run per 24 hours (day). $11.20 to run per week (8h/day).
You Should Not Leave Space Heaters on Unattended
We do not recommend using space heaters at all because of this risk, but you definitely should not use them at night. If your home is too cold at night, you may want to consider adjusting your thermostat to better meet your needs.
Running a space heater overnight increases the risk of fire. If the unit is left unattended or placed too close to flammable materials, such as curtains or bedding, it can ignite and lead to a devastating fire.
Greater Use of Home & Devices
Working from home increases energy usage. You may run your air conditioner more or keep your heat higher to be comfortable. Your computer, printer and other electronics will draw energy all day. You may need brighter lighting, too.
Adjust Your Thermostat
According to the DOE, reducing the thermostat setting by 7-10 degrees for 8 hours every day can reduce your average heating bill by up to 10%. Drop the temperature as low as you can without impacting pets and plants; this could be anywhere from 60 to 68 degrees Fahrenheit.
As mentioned, the power of an AC distributes heat throughout a room in minutes, and, up to three times more efficiently than electric heaters.
