This water heater has just a box-like unit that includes all mechanism that turns tap water hot. Inside, the box unit, you can find a heat exchanger, a burner or heating element, inlet and outlet sensors, valve, thermostats, piping, fan and electronic circuitry that controls heating and the fan.
How does it Work?
When you turn on the faucet, the water enters the heater and upon entering the heater, the electronic inlet sensor activates the burner which heats up the heat exchanger. Electric powered water heaters have no burner but instead, has the heating element that heats up with electricity. The pipe in which the water runs through gets hot thereby heating the water as well. When the water goes out of the outlet, it emerges hot and ready for use.
