Where are gas water heaters not permitted to be installed?

Gas water heaters are not permitted to be installed in a bathroom primarily due to safety concerns related to the potential for gas leaks and the presence of flammable materials in such enclosed spaces. Bathrooms often have limited ventilation, which increases the risk of gas accumulation if a leak occurs. Additionally, bathrooms are usually damp environments where humidity can interfere with the proper functioning of the water heater and create hazards, especially when combined with gas combustion.

In contrast, garages and workshops may have different safety specifications and can be designed with adequate ventilation or safety measures to accommodate such appliances. While installations in laundry rooms can also be done safely, they must adhere to local codes. Therefore, the prohibition of gas water heaters in bathrooms is aimed at ensuring the safety and health of occupants by minimizing the risk of accidents associated with gas appliances.
