What type of room heater may be installed in a bathroom?

Natural draft
Direct fired
Forced draft
Direct vent

The correct answer is: Direct vent

The direct vent type of room heater is suitable for installation in a bathroom because it uses a sealed combustion system that draws air from outside the home for combustion and then vents the exhaust directly outside. This design ensures that no indoor air is used for combustion, making it more efficient and safer for use in smaller, potentially humid spaces like bathrooms. Additionally, direct vent heaters have a lower risk of gas leaks or combustion byproducts entering the living area, which is particularly important in areas with limited ventilation. Given the high humidity levels in bathrooms, maintaining air quality and safety is crucial, and direct vent heaters accomplish this effectively. Natural draft, direct fired, and forced draft heaters could present safety hazards or inefficiencies in a bathroom setting due to their reliance on indoor air for combustion or their ventilation methods, which may not be suitable for a confined space.
