Room heaters are a popular solution for staying warm during the colder months. However, many people aren't aware that certain types of room heaters, especially those using combustion, can emit harmful carbon monoxide (CO) if not properly used or maintained.
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. If these types of heaters are in use, it is recommended that a working CO detector be used to indicate the presence of high-level CO gas.
The soot stain can have a black, brown or even yellow color. Smell: While carbon monoxide doesn't emit odor, it may get accompanied by other exhaust gases that produce an odor. A yellow burner flame: The pilot flame may produce an unusual yellow flame instead of the normal blue one.
Do Electric Space Heaters Produce Carbon Monoxide? No. Only heaters that burn a combustible fuel to create heat can cause carbon monoxide build-up in your home. An electrical heater works by having electricity flow through a metal heating or ceramic heating element to produce heat.
Sleeping with the heater ON increases the levels of carbon monoxide in the room above the safe level. The risk of asphyxia (sleep death) is high when using gas heaters. The excessive carbon monoxide in the room chokes the supply of blood to the brain, which can lead to hemorrhage and eventually death.
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.
Not too close. 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.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
Carbon Monoxide sources in the home
Homes with fuel-burning appliances or attached garages are more likely to have CO problems Common sources of CO in our homes include fuel-burning appliances and devices such as: Clothes dryers. Water heaters. Furnaces or boilers.
Don't leave the heater unattended for long
Always remember to switch off and unplug the appliance before leaving the room or going to bed. Prolonged usage of heaters in closed rooms can be dangerous as it can create carbon monoxide poisoning which can cause headache, dizziness, nausea and weakness.
Small carbon monoxide leaks can fill every room in your house with poisonous gas within eight hours. Severe leaks can cause this problem in just five minutes. The EPA states that exposure to concentrations of nine ppm or more for eight hours is enough to produce harmful health effects for at-risk individuals.
If your boiler is switched off at the mains, your boiler will not be burning fuel and therefore no waste carbon monoxide gas will be produced.
According to the CDC, carbon monoxide is a silent killer that takes hundreds of lives per year. Unfortunately, you cannot tell just by looking at your furnace whether it is leaking carbon monoxide. You need a carbon monoxide detector or other special equipment to test the levels yourself.
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.
Oil filled radiator space heaters are some of the safest on the market. 1500W is all the juice an outlet will provide (Roughly 5,000 btus).
If you experience symptoms that you think could be from CO poisoning: DO GET FRESH AIR IMMEDIATELY. Open doors and windows, turn off combustion appliances and leave the house.
If a refrigerator is an electric plug-in fridge, it cannot release carbon monoxide. However, some refrigerators run by burning gas such as propane, which can release carbon monoxide. RV refrigerators have this possibility, as do certain home fridges commonly found in off-grid homes.
Gas stoves. Generators and other gasoline-powered equipment. Automobile exhaust from attached garages.
Appliances that run on electricity do not produce carbon monoxide. CO can build up indoors and poison people and animals.
Go to the Home app on your iPhone or iPad. , then tap Home Settings. Tap Safety & Security. Tap Sound Recognition, then turn on Smoke & CO Alarm.
If you have a carbon monoxide detector chirping and then it stops, it's important to take the situation seriously, even if the alarm is no longer sounding. Even if the alarm has stopped, get everyone out of the home to a place with fresh air.
On a carpet, rug or flammable surface
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. You should also avoid using them on more delicate hardwoods or meltable vinyl, especially for long periods.
The CPSC calls it the “3-foot rule,” and it's pretty simple: Avoid placing a space heater within 3 feet of anything flammable. Some manuals list curtains, papers, furniture, pillows, and bedding as objects to stay away from.
Electric heaters of any type are unsafe to leave running overnight because they carry a significant amount of risk. 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.
