Water heaters must be certified by which of the following?

Water heaters are required to be certified by a third party to ensure they meet safety and performance standards set forth by regulatory bodies. This third-party certification process typically involves rigorous testing and evaluation to verify that the water heater complies with various codes and standards, including safety, efficiency, and environmental impact guidelines.

Having an independent entity conduct this certification helps consumers and professionals trust that the equipment is reliable and safe for use. While manufacturers may create products that meet certain standards, the third-party certification adds an additional layer of verification, ensuring that the products are not only designed for compliance but have also been tested in real-world conditions. This system helps enhance consumer protection, ensuring water heaters operate as intended while adhering to legal and safety requirements.
