The inner tank is metal with a bonded glass lining to deter rust and corrosion and ensure clear, clean water. The anode is a metal rod immersed in water that adds extra protection against corrosion and extends the life of the tank.
Thermostats control each heating element and maintain the required water temperature.
A safety limit control shuts off electric current when the water temperature limit is reached to protect against over-heating. Single or dual-type immersion heating elements are sheathed in copper and provide complete contact with water for instant heat transfer and fast recovery. A non-corrosive inlet directs cold water in the bottom of the tank without affecting hot water in the upper section. The drain valve allows you to drain sediment from the bottom of the tank. The pressure relief valve is a safety device to prevent excessive temperatures or pressures inside the tank.
