What is a storage tank water heater and how does it work?
A storage tank water heater is a common type of water heating system that is found in many homes and buildings. It consists of a tank, typically made of steel, that is used to store and heat a large quantity of water. The tank is usually insulated to help retain heat and keep the water hot until it is needed. The working principle of a storage tank water heater is relatively simple. Cold water enters the tank through a supply line and is deposited at the bottom of the tank. Inside the tank, there is a heating element, such as a gas burner or an electric heating element, which raises the temperature of the water. As the water is heated, it becomes less dense and rises to the top of the tank. This creates a circulation pattern known as convection, where hot water rises and cold water sinks. When hot water is requested, it is drawn from the top of the tank through a hot water outlet. To maintain a constant supply of hot water, the storage tank water heater continually heats the water inside the tank, even when hot water is not being used. This can lead to energy inefficiency and higher energy bills, especially if the tank is poorly insulated.
