Electrical Problems: If your heater is tripping the circuit breaker, there's an underlying issue. It's safest to stop using it until the problem is addressed.
Using the heater too often could lead to undesirable consequences like leaving out skin or nasal passages dried out. It Can Cause Carbon Monoxide Poisoning-It's important to keep your space heater in good working order so you don't have any accidents or health problems.
But when is the right time to flip the switch? Start by shutting off your heating system when temperatures are consistently above 50 degrees Fahrenheit. While that temperature might seem cold, it can take days for your whole home to cool down to that temperature. So you can turn the heat off and see how you feel.
Space heaters are designed to run for a few hours and warm a small space. These units aren't intended to run all day or night, operating without stopping for eight hours or more.
At least 3 feet of clearance must be maintained around the heater at all times. Combustible materials like paper, plastic, and cloth must be kept away from the heater. Electric cords must be kept out of foot traffic paths to prevent tripping.
The duration for which you can leave a space heater running depends on the time of day and your specific needs. During the Day: It's safe to leave your heater on for 6-8 hours if you're in the room. If you're busy or moving between rooms, consider using a timer to automatically shut it off after a few hours.
Using a space heater can be a good way to boost the temperature in a small, drafty room—and it could be less expensive than cranking up your central heating system. But a space heater is economical only if you use it judiciously.
Overusing the heater or using an oversized heater can result in elevated levels of carbon monoxide or nitrogen dioxide fumes in the air. These fumes can cause cold or flu-like symptoms, headaches, and eye, nose and throat irritation.
What is the safest heater to leave on overnight? While it's not recommended to leave any space heater on if you're not monitoring it, oil-filled, radiant space heaters are considered safer than ceramic convection (hot air) types, according to Roberson. Both of these options are safer than open-coil heaters.
Never leave a space heater running for long periods of time, and especially not overnight; it is best to use them intermittently; depending on your situation, a suggested practice would be to turn it off/unplug it for 10 minutes every hour if you depend on its use for longer periods.
Space heaters can take anywhere from 750 watts to 3,000 watts to operate. Large space heaters take immense amounts of energy to run. However, those are most likely used only in commercial and industrial settings. The average residential space heater has two main heat settings, low and high.
We recommend turning off your heating system whenever the temperature consistently reaches 50° F outdoors. This doesn't mean you must shut off your heating system entirely. Instead, it simply means that you should be able to at least shut it off throughout the daytime hours to help save money on your energy bills.
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.
Room heaters can cause dryness in the air, which can result in dry skin, dry eyes, and dry throat. This can further lead to respiratory issues, nasal congestion, and increased susceptibility to infections.
CPSC estimates that space heaters, including both fixed and portable heaters, are associated with about 21,800 residential fires every year. About 300 people die each year in fires started by these heaters.
Recommended Usage Times. During the Day: It's generally safe to run your space heater for 6 to 8 hours during the day while you're home and active.
Maintained Comfortable Room Temperature:
By leaving your heating on overnight, you can maintain a consistent and comfortable room temperature, keeping you and your family warm all night. This can result in better sleep, better health, and a more pleasant living environment.
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.
Portable space heaters can get very hot and ignite nearby objects, by either tipping over or being in close proximity to these objects. The heater's exposed heating coils or elements can spark a fire in seconds. Overloading an outlet may cause an electrical fire or lead to the appliance overheating.
The estimated life expectancy of these heaters ranged from 5 to 12 years with an average of about 8 years of useful life.
Most home heating deaths happened because a space heater was too close to furniture, clothing, mattresses, or bedding. Make sure your heater is at least three feet from anything that can burn.
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.
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).
