Can a natural draft water heater be installed in a bedroom?

Natural draft water heaters are designed to vent combustion gases through a flue that relies on natural airflow to operate effectively. Installing these types of heaters in a bedroom is generally not permitted due to safety concerns. The primary risk stems from the potential for carbon monoxide buildup, as natural draft systems may not provide sufficient ventilation in enclosed spaces.

Bedrooms typically lack the necessary airflow required to safely disperse combustion gases, making it dangerous for occupants. Local codes and regulations often specify that combustion appliances, like natural draft water heaters, should be installed in areas with adequate ventilation and air exchange, such as basements or utility rooms. Thus, the prohibition against installing a natural draft water heater in a bedroom is based on health and safety considerations, ensuring that harmful gases do not accumulate in living spaces where people sleep.
