Portable space heaters that use a fuel source such as propane or kerosene can release toxic fumes and gases, such as carbon monoxide. To avoid the risk of carbon monoxide poisoning, use only electric space heaters and never place a fuel-burning space heater in an enclosed space (such as an apartment).
According to the Consumer Product Safety Commission, space heaters are involved in more than a thousand home fires every year.
Long-term use of heaters in enclosed spaces can be hazardous because it increases the risk of carbon monoxide poisoning, which can lead to headaches, nausea, dizziness, and weakness.
Heaters must be kept at least three feet away from anything that can burn, including papers, clothing and rugs. Locate space heaters out of high traffic areas and doorways where they may pose a tripping hazard.
Most properties have guidelines that restrict the use of open-flame appliances due to their high risks. The restrictions are meant to protect other tenants and the property.
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.
Best Space Heater Safety Tips
These appliances are intended to sit on the floor, not on a table. Establish a 3-foot kid- and pet-free zone around the heater, and never put a space heater in a child's room. Keep the space heater at least 3 feet away from combustible materials, such as furniture, bedding, and curtains.
Sleeping with a room heater on in a closed room can increase carbon monoxide levels, reduce oxygen, and disrupt blood flow to the brain, potentially leading to brain hemorrhage or death.
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.
According to the National Fire Protection Association (NFPA), space heaters account for 43% of home heating fires and 85% of home heating deaths. They can also be a hazard in the workplace. While there are no federal safety rules prohibiting space heaters at a worksite, you should follow local rules and regulations.
According to the CDC (Centers for Disease Control), at least 430 people die annually in the U.S. from accidental carbon monoxide (CO) poisoning. While electric space heaters do not produce carbon monoxide (CO), non-electric space heaters (propane gas, natural gas, kerosene, wood) can if incomplete combustion occurs.
Space heaters can pose potential risks if not used properly. They have the potential to cause fires if placed too close to flammable materials or left unattended. Additionally, using extension cords that are not rated for the heater's power can increase the risk of overheating and electrical hazards.
If there is ductwork or plumbing to spread the heat of a sufficiently large heater, a building can be heated from a single electric source. I would not try to heat a four room apartment with a single 2500W “space” heater.
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.
If a space heater falls over or becomes too hot from running for too long of a period of time, that can lead to a fast-moving fire that occurs while you are asleep and cannot act fast enough. We do not recommend using space heaters at all because of this risk, but you definitely should not use them at night.
Space heaters can't sit on any surface that can easily scorch or catch on fire. That means you can never place one on a carpet or rug.
The U.S. Consumer Product Safety Commission estimates that more than 1,700 residential fires every year are associated with the use of space heaters, resulting in more than 80 deaths and 160 injuries nationally.
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.
That being said, ceramic space heaters are safe to leave on all night because the outside shell does not heat up and thus remains cool, posing no harm to you or your family. Ceramic heaters are among the safest heaters to use throughout the night.
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.
