The answer to 'how does water heater installation work' is that installing a new water heater typically involves several key steps. First, the old water heater must be disconnected from the gas or electric supply, as well as the cold water inlet and hot water outlet pipes. The old unit is then removed, and the area is prepared for the new water heater. Next, the new water heater is positioned in the designated location, and the connections are made to the gas or electric supply, as well as the water pipes. Finally, the water heater is filled, and the system is tested to ensure proper operation.
The entire process can take several hours, depending on the complexity of the installation and any additional work required, such as upgrading electrical service or modifying plumbing. It's important to follow all manufacturer instructions and local building codes to ensure the water heater is installed safely and correctly.
