kerosene heaters

I think y'all are confusing C2O2 with CO2. Any flame will use oxygen and produce carbon dioxide. OTOH, carbon monoxide is poisonous. I'd like to hope there would be a gov ban on them for if they were spewing that inside homes.

As for the OP's question, it may affect your pH as O2 levels fall and CO2 rises, but you're probably in more danger than your fish if your house is well-sealed. I wouldn't run it long-term without cracking a nearby window.

 

Mr. Bill i have to respectfully disagree with ya on this one!
What is carbon monoxide (CO) and how is it produced?


Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. It is produced by the incomplete burning of various fuels, including coal, wood, charcoal, oil, kerosene, propane, and natural gas. Products and equipment powered by internal combustion engines such as portable generators, cars, lawn mowers, and power washers also produce CO.
How many people are unintentionally poisoned by CO?


On average, about 170 people in the United States die every year from CO produced by non-automotive consumer products. These products include malfunctioning fuel-burning appliances such as furnaces, ranges, water heaters and room heaters; engine-powered equipment such as portable generators; fireplaces; and charcoal that is burned in homes and other enclosed areas. In 2005 alone, CPSC staff is aware of at least 94 generator-related CO poisoning deaths. Forty-seven of these deaths were known to have occurred during power outages due to severe weather, including Hurricane Katrina. Still others die from CO produced by non-consumer products, such as cars left running in attached garages. The Centers for Disease Control and Prevention estimates that several thousand people go to hospital emergency rooms every year to be treated for CO poisoning.

 

That being said, it;s still probably a good idea to have one as a back up! i may go get one! I do have carbon monoxide detectors in my home though as i have an OLD gas furnace and fireplaces!
