Comments on: Can space heaters emit CO2? ?

CH is slightly misinformed about fuel-burning space heaters. Initially, they do produce CO2, not CO. However, they do require a fresh supply of O2. In a sealed space, they will eventually use up so much O2 and fill the room with so much CO2 that the CO2 is all they have left to consume for oxidizing the fuel. In that case, they start producing CO.

Built-in gas heaters will also produce CO if you cut off the flow of fesh air to their combustion chambers. So replace dirty filters and don’t pile boxes in front of them.

CO is deadly and odorless, but if you can smell the CO2, you can be pretty sure that CO is also present at a dangerous level.

If it’s electric, it shouldn’t produce any gases whatsoever. However, if it burns something like methane, then yes, it produces CO2 gas.

EDIT: CO2 is something you breathe out, though. It won’t kill you. CO would kill you, but hydrocarbons produce CO2, not CO.

if it does burn hydrocarbon type fuel .It does not produce Carbon Monoxide.

An electrically-powered space heater will only give off CO2 if you burn it, from the paint, insulation, and so on. Mind, if the rheostat (or thyristor) has failed, you should have it checked over to ensure that there isn't an electrocution (or fire!) risk.
