Built-in recirculation system
Navien’s patented ComfortFlow® system is the first to include a buffer tank, recirculation pump, and fine-tuned controls in a tankless water heater. This resolves the cold-water sandwich effect* and issues of minimal flow rates commonly found in other tankless water heaters.
