The Role Of Upper And Lower Water Heater Elements
The upper and lower water heater elements serve different purposes in heating water. The upper element is responsible for heating the water at the top of the tank. Once the top of the tank reaches a certain temperature, the upper element shuts off, preventing the water from becoming too hot. On the other hand, the lower element heats the water below the top of the tank.
This dual-element system allows the water heater to provide a continuous supply of hot water. By heating the water from both the top and the bottom, the water heater can efficiently maintain a constant temperature throughout the entire tank. This is especially beneficial in households where hot water demand is higher, ensuring a sufficient supply of hot water for all users.
- The upper element heats the water at the top of the tank.
- The lower element heats the water below the top of the tank.
