Tankless water heating The main advantages of tankless water heaters are a plentiful continuous flow of hot water (as compared to a limited flow of continuously heated hot water from conventional tank water heaters), and potential energy savings under some conditions. A tankless water heater only heats water on demand, so idle water in the piping starts at room temperature. 2  Thus, there may be a more apparent flow delay for hot water to reach a distant faucet (in non-point-of-use systems).

Home Tech: Tankless Water Heaters Explained Demand water heaters ditch the giant storage tank and instead warm up moderate amounts of water when needed. As water flows through the device, a heating element — either a gas burner or an electrical element — warms it up. As soon as the hot water faucet is turned off, the heating element shuts down. Without a tank of water constantly warming, standby heat loss is eliminated. According to the National Association of Home Builders, tankless systems can cut 10 to 20 percent off your water-heating bill.
