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

The maximum allowed BTU for unvented space heaters in a bathroom is specified as 6,000 BTU/hr. This limit is in place primarily for safety and health reasons. Unvented space heaters release combustion gases directly into the room, and higher BTU ratings could increase the risk of elevated carbon monoxide levels and other safety hazards.

This regulation helps to minimize the risk of creating an unsafe environment, especially in smaller, enclosed spaces like bathrooms where ventilation may be limited. Such restrictions are essential to ensure that there is a balance of heating needs without compromising air quality or safety.

It's worth noting that while other BTU ratings may apply to different types of installations or use cases, the key here is the specification for unvented space heaters in specific areas like bathrooms, thereby keeping safety at the forefront of heating solutions.
