What should be paid attention to when installing an electric water heater?

The installation quality of an electric water heater directly affects its safety and lifespan. It needs to be strictly controlled from multiple aspects such as location selection, pipe connection, and safety device configuration, and follow professional specifications.

Location selection needs to take into account both load-bearing and environment. The installation wall must be a solid load-bearing wall that can withstand the weight of the water heater when it is full of water. Avoid installing it on a lightweight partition wall or hollow brick wall to prevent the risk of falling off. At the same time, it should be kept away from flammable materials and kept at a distance of more than 1.5 meters from gas stoves and power sockets. A well-ventilated location can reduce the impact of moisture on the circuit. For bathroom installation, a model with a waterproof rating of IPX4 or above should be selected.

Pipeline connection focuses on adaptability. A check valve needs to be installed on the water inlet pipe to prevent hot water from backflowing and affecting the cold water supply; high-temperature resistant PPR pipes should be used for the inlet and outlet pipes, and the raw tape should be wrapped around the interface and tightened to ensure no leakage. The direction of the pipe should avoid excessive bending, and right-angle elbows should be used at the bends to reduce water flow resistance. It is recommended to test the newly installed pipes with water first and connect the water heater after confirming that there is no leakage.

The installation of safety devices cannot be omitted. An independent leakage protection switch must be equipped, and it must match the power of the water heater. The installation position should be 1.5-1.8 meters from the ground to facilitate operation in emergency situations. The safety valve must be installed vertically at the water inlet to ensure that the valve core operates normally. The pressure relief port should face the unmanned area to avoid hot water scalding during pressure relief. For storage water heaters, maintenance space must be reserved, and the distance between the front and the wall must be no less than 60 cm.

The circuit configuration must be professional and standardized. The power cord must use copper core wire, and the cross-sectional area is selected according to the power. 2.5 square millimeters are used for less than 2000W, and 4 square millimeters are used for more than 2000W. The wiring should be separate to avoid sharing the circuit with other high-power electrical appliances. The socket must be firmly fixed to avoid looseness and poor contact. The bathroom socket must be equipped with a splash-proof box to prevent water vapor from invading and causing a short circuit.

A comprehensive test is required after installation. Before turning on the power, check whether the pipe connection is firm, open the water inlet valve to fill the inner tank with water, and then turn on the power after confirming that there is no water leakage, test whether the heating function is normal, and check whether the leakage protection switch is sensitive. The installer needs to explain the precautions for use to the user and keep the contact information for subsequent maintenance.

Standardized installation can reduce more than 80% of usage failures, which not only ensures the safety of household water use, but also prolongs the service life of the electric water heater. It is the basic link to ensure the performance of the product.
