A storage tank water heater is water-heating container that uses a large tank to store hot water until it is needed. This type of water heater is typically powered heating steam or gas, and is used to provide hot water for a variety of uses, including showers, dishwashing, and laundry, or other hot water requests alike. The tank is typically insulated to help maintain the water temperature and reduce energy costs. Storage tank water heaters are a popular choice for many households because they are relatively inexpensive and can provide hot water for multiple uses.
Typical heat exchanger structure is heating spiral coil inside of a steel shell. Water will be heated while passing through inside the coil, and received the energy or heat from hot steam or gas.
The main disadvantage of a storage tank water heater is that they are less energy efficient than tankless water heaters. This is because they continuously heat and reheat the same water, which can waste energy. Additionally, storage tank water heaters require more space than tankless water heaters, as they are larger in size.
In that sense, recent years are seeing storage tank water heat exchanger giving way to other efficient products, such as Shell And Tube Heat Exchanger, Plate And Frame Heat Exchanger, and so on.
