Storage tank water heaters store water in a large tank to use whenever it is needed. First, cold water enters through a tube that leads to the bottom of the tank. Then a heating mechanism—either a gas-powered burner or an electric-powered heating element—heats the water, which rises to the top of the tank since hot water naturally rises above the denser, colder water. A tube sits at the top of the tank to supply hot water to the home, and cold water continues to cycle in as a replacement.
The problem with storage tank water heaters is the standby energy loss associated with continuously heating standing water. With a tankless heater, water is heated instantly to eliminate this loss. Tankless water heaters simply work through the use of a heat exchange system. Electric coils or gas activate to generate heat as soon as a hot water tap is turned on in the house so that hot water can immediately reach the faucet. Tankless water heaters may not be able to handle multiple jobs at once, so some homes may have several tankless water heaters, each mounted near the tap that activates it.
