Navien NPE-210S Tankless Water Heater + Grundfos Circulating Pump

After Navien replaced my 180 that froze during an extreme cold snap, I replaced it with a Navien NPE-210S. I added a Grundfos circulating pump so that the water is warm as soon as the tap is turned on. During the winter, the warm supply line helps to heat the house.
