How it works
How a Navien Tankless Water Heater Works
What happens inside an NPE-2, from the moment a hot water tap is opened:
- 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 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

Energy efficiency
The Ultimate in Energy Efficiency
Navien condensing technology provides up to 0.96 UEF. These extremely efficient and eco-friendly units provide extra energy savings over traditional tank and non-condensing tankless water heaters.
Operating cost
Estimated yearly natural gas use and cost
* Based on Energy Guide cost estimates using $1.09 per therm of natural gas. Cost is in US dollars.
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.
Questions
Navien Tankless Water Heater FAQ
Answers to the questions homeowners ask about Navien tankless water heaters.
How does a Navien on-demand water heater work?
When a hot water tap is opened, a Navien NPE-2 detects the flow, works out how much hot water is needed, and lights its premix burner to heat the water as it passes through two stainless steel heat exchangers. You get all the hot water you need, for as long as you need it, and it isn’t heating water when you don’t.
What is the difference between the Navien NPE-A2 and NPE-S2?
Both are condensing tankless water heaters in the NPE-2 Series. The NPE-A2 (Advanced) has ComfortFlow® built in: an insulated buffer tank and a recirculation pump, which saves water and reduces the time to get hot water. It also works with the optional H2Air kit for combined space heating and hot water. The NPE-S2 (Standard) has no built-in pump, so recirculation needs an external pump.
How energy efficient is a Navien tankless water heater?
Navien condensing technology provides up to 0.96 UEF, and the NPE-180, NPE-210, and NPE-240 models are ENERGY STAR® certified. In Navien’s Energy Guide comparison, an NPE-2 uses about 179 therms of natural gas a year, against 209 for a non-condensing tankless and 269 for a standard tank.
What warranty comes with a Navien NPE-2?
Navien’s residential warranty covers the heat exchangers for 15 years and parts for 5 years on a standard or controlled-recirculation install.
How much space does a Navien tankless take up?
About 80% less than an old-fashioned tank heater. An NPE-2 hangs on the wall and measures 17.3 in. wide, 27.4 in. high, and 13.2 in. deep, and its exhaust is cool enough that economical Schedule 40 PVC pipe can be used for venting in almost all applications.
