No, ceramic space heaters do not produce carbon monoxide.
Yes, ceramic space heaters are widely considered one of the safest options for indoor heating. They utilize self-regulating ceramic plates that eliminate the need for exposed, red-hot heating coils. When operated correctly, they present a significantly lower risk of burns and accidental fires than traditional alternatives.
The heaters that can produce carbon monoxide include the following: Gas heaters, whether fueled by propane or natural gas. Kerosene heaters. Wood stoves.
While ceramic heaters are generally considered safe due to internal heating elements and cool-touch exteriors, fire safety experts and government agencies do not recommend leaving them on overnight while you sleep. Unmonitored heating poses severe fire and electrical hazards.
The greatest sources of CO to outdoor air are cars, trucks and other vehicles or machinery that burn fossil fuels. A variety of items in your home such as unvented kerosene and gas space heaters, leaking chimneys and furnaces, and gas stoves also release CO and can affect air quality indoors.
It is also a good idea to know the signs of a potential CO problem:
Carbon monoxide (CO) is widely known as the "silent killer" gas. It gets this name because it is completely invisible, tasteless, and odorless, meaning it can build up to lethal levels in a room without the victim ever realizing they are breathing it in.
No space heater is 100% safe to leave completely unattended for long periods. However, oil-filled radiators and modern infrared heaters are the safest options. They do not use exposed heating coils and run cooler, but must always have built-in safety features like tip-over shutoff and overheat protection.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
It is generally not recommended to sleep with a space heater on. While modern electric models with safety features are much safer than older units, leaving a heater running unattended poses severe fire hazards, carbon monoxide risks (for fuel-burning models), and can dry out your airways.
The safest small space heaters are ceramic heaters with built-in safety features like tip-over switches, overheat protection, and cool-touch exteriors.
Carbon monoxide is called the silent killer. You can't see it or smell it, but it can make you very sick or even be deadly. This November, take simple steps to protect your home and family: Check your CO detectors, inspect appliances, and never use generators or fuel-burning tools indoors.
Do Space Heaters Give Off Toxic Fumes? Space heaters that use kerosene or gas as a fuel give off carbon monoxide. This type of space heater is generally not recommended for indoor use.
While ceramic heaters are excellent for quickly warming small, localized areas, they have notable drawbacks. Their primary disadvantages include a lack of heat retention, a limited heating range, noise from built-in fans, and safety hazards if misused.
Are infrared heaters safer than ceramic heaters? Yes. Infrared heaters have no exposed heating elements or fans, reducing fire hazards. Also, since they don't circulate air, they don't circulate allergens.
The Risk of Space Heater Fires
One third of fires in the home are caused by space heaters.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
Heating and energy expert Stephen Hankinson said that one "big energy cost saver" is to make sure you have your heating off when you're not at home. For instance, if you typically arrive home from work at around 6pm on weekdays, you could set your heating to activate just as you walk through the door.
A detailed study from the National Renewable Energy Laboratory found residents preferred a wintertime heater setting between 67 °F and 70 °F (19 °C to 21 °C). The Department of Energy recommends a winter heat setting of 68 °F (20 °C), which matches up very well with the temperatures most of us are comfortable with.
Consumer Reports tests space heaters primarily on room heating ability, spot heating, and strict fire and safety criteria, such as overheat protection and tipping tests. Highly rated models often cost around $75 to $100 and feature auto-climate control and tip-over shut-offs.
Portable propane heaters are one of the most effective ways to provide heat during a power outage. Many models are designed for indoor use and equipped with safety features like oxygen depletion sensors and tip-over switches.
To heat a room without a heater, trap existing warmth and insulate your space. Block drafts under doors using a rolled-up towel or Draft Stoppers, cover drafty windows with bubble wrap or clear film, and use Thermal Curtains to block the cold.
Carbon monoxide poisoning is the suspected cause in the death of 76-year-old Dayle Haddon, a Canadian supermodel best known for being the face of the makeup brand L'Oréal. Haddon died Friday at the Solebury Township, Pennsylvania home of her actor son-in-law, Marc Blucas.
Cyanide is one of the deadliest poisons, which can cause death to those who come into contact within a few minutes or hours of exposure, depending on the level and route of exposure.
Medical professionals widely recognize hypertension (high blood pressure) as the number one "silent killer". It is dubbed "silent" because it rarely produces noticeable symptoms while internally damaging the body, and a "killer" because it is the leading primary risk factor for fatal conditions like heart attacks and strokes.
