Navien makes
it easy to go tankless
“We were tired of running out of hot water, high energy bills and the idea of constantly heating a big old water storage tank. That's why we asked our contractor to install a Navien Premium Efficiency (NPE) tankless water heater. We researched the Energy Star website and found Navien on top of the energy factor list. Now we get endless hot water when we need it and we’re not heating water when we don't.”

How Non-condensing 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 burner ignites providing a flame to heat the water
Cold water passes through the heat exchanger
The unit determines outgoing set temperature and adjusts the flame to heat the water
Desired hot water amount delivered to the faucet
Navien NPN Premium Non-Condensing Tankless Water Heaters
Introducing The New NPN Series
Compare our advantages to other non-condensing tankless water heaters
Exclusive Navien NPN-Universal indoor or outdoor unit and NPN-Exterior dedicated outdoor unit. NPN-E outdoor models also feature remote control and built-in button controls for easy service.

For increased domestic hot water flow demand, the NPN can be cascaded with another NPN unit.
NaviLink™ Wi-Fi remote control.
This optional accessory enables you to control temperatures remotely, access usage data and receive diagnostic notifications from your smart phone or tablet.
Space saving and lighter weight design.
These sleek wall-hung units use much less space and are substantially lighter than traditional tank water heaters and other non-condensing tankless water heaters.
Low noise levels.
Installations in or near media rooms, recreation rooms or any living areas of the house are possible with the quiet running NPN tankless water heaters.
Lower energy bills, easier on the planet.
Unlike systems that waste energy to heat large tanks of water, Navien NPN series tankless units utilize 82¢ of every $1 to heat your water. NPN only fires up when hot water is needed allowing great utility savings and a lower impact on the environment.
How Condensing 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

Innovations make Navien condensing tankless water heaters the best choice for homeowners
Dual stainless steel heat exchangers last longer than copper
Condensing technology reduces energy consumption and greenhouse gas emissions
For homes with extra high demand, NPE Series units can be cascaded without an external control
Optional NaviLink™ Wi-Fi control system gives you access to your Navien systems from anywhere in the world
NPE-A series models feature ComfortFlow® internal recirculation system which saves water and reduces time to get hot water
HotButton recirculation activation option for NPE-A models

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.
