WHAT IS THE DIFFERENCE BETWEEN CO AND CO2?
Is it dangerous to fall asleep with a fireplace on?
Are combustion products toxic?
Is there a risk of asphyxiation in your sleep?
To give these questions a proper answer, we first have to clarify what combustion products are.
Bioethanol combustion occurs through the consumption of oxygen and the emission of CO2 (carbon dioxide or carbon dioxide).

WHAT IS CO2:
Carbon dioxide, or CO2, is a gas present in nature in large quantities: we emit it ourselves while breathing and it is part of the atmosphere.
When the level of oxygen drops in an environment and that of CO2 rises, our body is equipped to recognize the situation: this happens when there is a smell of stale air.
If the CO2 level drops while we are sleeping, we wake up feeling the need to change the air of the room.
It is important to remember that a bioethanol fireplace generally has a limited autonomy of a few hours.

WHAT IS CO:
Carbon monoxide, or CO, on the other hand is very dangerous: it binds to the hemoglobin instead of oxygen, deceiving our body.
For this reason, if asleep we do not wake up and there is a real risk of asphyxiation.
CO is typically produced by the incomplete combustion of gas appliances, such as heaters and boilers, that often lead to serious domestic accidents.
CO is typically produced by the incomplete combustion of gas appliances, such as heaters and boilers, that often lead to serious domestic accidents.
In bioethanol fireplaces the production of CO is infinitesimal, therefore negligible.
A cycle with zero emissions:
Furthermore, the bio-fireplace does not increase the greenhouse effect, since it is a fuel obtained from the fermentation of vegetables (sugarcane, beet or corn), it returns the CO2, once removed from the atmosphere by plants, to the environment. A closed circle with zero emissions.
So now you will understand why the answer to the questions mentioned at the beginning of this in-depth study is NO.
