The installation of a water heater that relies on combustion for heat is strictly prohibited in a bedroom due to safety concerns. Bedrooms are considered sleeping areas, and the presence of a combustion appliance can pose significant risks, such as carbon monoxide poisoning and fire hazards. When fuel is burned for heating, it produces byproducts, including carbon monoxide, which can accumulate in enclosed spaces, especially if ventilation is inadequate.

The safety codes and regulations are designed to minimize these risks by restricting the locations where these types of water heaters can be installed. Areas such as garages, kitchens, and basements may have more ventilation and access to safety features that mitigate these risks, but bedrooms typically do not have the same safety considerations. Therefore, the prohibition of combustion-fueled water heaters in bedrooms is a precautionary measure to ensure occupant safety.
