Another Navien tankless water heater swap out. This one replaced a 100 gallon tank type water heater which took up a good third of the closet. With the extra room we added a laundry sink adjacent to the tankless.
Also included is a picture of the internals. Lots of things happening inside these units which is why it's important to properly size the units with use as well as protect the heat exchanger from mineral build up. This install was in a Fire station Barracks and now they will have endless hot water, shower after shower.
