Categories Related to Hot Water Tanks
A hot water tank, also known as a storage tank, is a container used for storing hot water for heating and domestic hot water supply.
Large-scale tanks are commonly installed in facilities such as schools, hospitals, kitchens, nursing homes, and food factories, where there is a need for a substantial amount of hot water at once. Smaller tanks, with capacities ranging from 300L to 500L, are also used in households, particularly as part of hot water supply systems like heat pump water heaters.
These tanks are made of materials such as stainless steel and a mechanism for insulation. They typically include a temperature sensor, and water is heated to the desired temperature using a heat exchanger and then returned to the tank, maintaining a consistent temperature. Some tanks have a heating coil inside. Tanks are classified as articulated heating tanks if they have a coil, and as direct heating tanks if they don't.
