Navien NPE-240A2 Tankless Water Heater

Navien NPE-2 series tankless water heaters replace inefficient tank heaters, saving water, natural gas and electricity with the added benefits of endless supply of hot water, lower maintenance costs and longer product life. With the Navien NPE-A2, you get Navien’s patented ComfortFlow® system, the first to include a buffer tank, recirculation pump and fine-tuned controls into a tankless water heater that resolve the cold-water sandwich effect and minimal flow rate issues commonly found in other tankless water heaters.
