Some units call it by a diverse name, on the other hand all units have some kind of flow switch that turns the heater on when a faucet is opened from the house.
Once a hot water faucet is turned on, the unit automatically turns on and starts to heat the water. The gas burner is designed to heat the water really, really quickly, so quickly that it actually heats the water as soon as the cold h2o passes as a result of the heater itself.
The main benefit or feature of a tankless gas water heater is like the advertisements say, you will never uses up hot water. As mentioned earlier, the design and capability to heat water as quickly as it passes as a result of stashed away why it can heat the water if there is a hot water faucet open from the house.
