How Gas Instant Water Heater Works
A natural gas or propane instant water heater in the home will be connected directly to the water supply line for hot-water-on-demand use. And when you turn on a hot-water tap, the flow sensor in the water heater will sense that there is a flow and turn on the burner. Water in the system is circulated through a heat exchanger to heat it to a certain degree, and then hot water is supplied continuously. Close the tap, and then the device will shut down by itself to save power.
