No one should use an unvented combustion heater. It is an unwise choice.

This is what I found....
CO alarms are made to go off at the maximum 24hour exposure level NOT the the long term exposure levels that OSHA set.
A 9000BTU Mr.Buddy heater emits 1 cup of water into the air every hour it runs. With a family of 4 + a dog + a heater we'll have mold everywhere.
Once proper ventilation is provided there is no heat being added.
