HOW TANKLESS WORKS

learn how this on-demand technology can save your utility bills.

step1 STEP 1 A shower or other hot water valve is turned on.
step1 STEP 2 Cold water enters through the flow sensors to trigger the internal computer.
step1 STEP 3 The computer calculates how hot to set the burners to deliver water at the perfect temperature.
step1 STEP 4 Water quickly circulates around the heat exchanger to reach the designated temperature and exits the heater.
step1 STEP 5 The heater shuts down and stops using energy when there is no more demand for hot water.
