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.”
