All the hot water you need, for as long as you need it.
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.”
Non-Condensing VS Condensing
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
