How it works
When a hot water tap is opened, the tankless water heater detects the flow
The flow sensor activates to determine the amount of hot water needed
The igniter activates
The gas control valve opens to supply the correct amount of gas
The fan and venturi activate to provide the correct amount of gas and fuel
The premix burner ignites providing a flame to heat the water
Cold water is pre-heated in the secondary heat exchanger
Pre-heated water passes from the secondary to the primary heat exchanger
The unit determines outgoing set temperature and adjusts the flame to heat the water
Heated water moves to the buffer tank
Desired hot water amount delivered to the faucet
