What is the maximum allowed BTU for unvented space heaters in a bedroom?

The maximum allowed BTU for unvented space heaters in a bedroom is capped at 10,000 BTU per hour. This regulation is in place primarily to ensure safety and prevent the accumulation of dangerous levels of carbon monoxide and other harmful gases in confined spaces like bedrooms. The limit is designed to address the potential risks associated with using unvented heaters, which can potentially deplete oxygen levels in small areas and lead to serious health hazards if not properly monitored.

This safety regulation encourages the use of unvented space heaters in lower capacities, as higher output would pose a greater risk. Understanding these regulations is crucial for ensuring the safe operation of heating appliances in residential settings.
