Tankless Water Heating - How Does It Work?


 

   
No.Description
1 When a hot water tap is opened the unit detects the flow.
2 The flow sensor activates to determine the amount of hot water needed.
3 The igniter activates.
4 The gas control valve opens to supply the correct amount of gas.
5 The fan and venturi activate to provide the correct amount of gas and fuel.
6 The premix burner ignites providing a flame to heat the water.
7 Cold water is pre heated in the secondary heat exchanger.
8 Pre heated water passes from the secondary to the primary heat exchanger.
9 The unit determines outgoing set temperature and adjusts the flame to heat the water
10 Heated water moves to the buffer tank
