  3. The igniter activates

  4. The gas control valve opens to supply the correct amount of gas

  5. The burner ignites providing a flame to heat the water

  6. Cold water passes through the heat exchanger

  7. The unit determines outgoing set temperature and adjusts the flame to heat the water

  8. Desired hot water amount delivered to the faucet

  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

Protect the environment as you add value

Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless water heaters to reduce energy consumption and CO₂ emissions. That keeps exhaust temperatures very low — so low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.

The ultimate in energy efficiency

Navien condensing technology provides up to 0.97 UEF /0.99 EF. These extremely efficient and eco-friendly units provide extra energy savings over traditional tank and non-condensing tankless water heaters.
