It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank through the dip tube where it is heated, ensuring that the tank is always full. Gas and oil water heaters also have venting-related energy losses.
How does a hot water storage tank work?
Storage tank water heaters use either fuel such as natural gas or electricity to heat water. In a fuel-burning system, a thermostat triggers the system to burn fuel for heat when the water’s temperature falls. When the temperature reaches the setpoint, it triggers the system to stop burning fuel.

How long do storage tank combustion water heaters typically last?
In contrast, storage water heaters last 10–15 years. Tankless water heaters can avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a constantly burning pilot light.
