Thank you for your feedback. It is very important to us.
There will always be a smell with gas heaters. Gas is being burned inside the unit, the combustion process is happening. It all depends on how it would affect you. If you have had gas heaters before, you will not notice it. If you have not, we would advise visiting someone who has one before purchasing.
“The heater is very dangerous because it is producing a lot of carbon monoxide gas. I have to open windows to bring in fresh air which is cold air which defeats the purpose. I wouldn't recommend it to other people.”
Thank you for your feedback.
All gas heaters will produce carbon monoxide. It is the offset of the gas being burned inside the heater. This is why all gas heaters have minimum room size requirements.
All gas heaters are fitted with an oxygen depletion sensor as a safety feature, so they are not dangerous. If the carbon monoxide builds to an unsafe level inside a smaller room, the heater will turn off and not allow it to restart until the room has been ventilated.
Smaller rooms may need a window or door open to draw in ventilation for the heater. This is why you are always advised to check the minimum room size requirements before ordering a gas appliance.
