Navien Tankless Water Tank Firstly let’s get this straight; Navien is a brand of tankless hot water heater not Navian.I have seen this spelled wrong many times, Navian (I googled it) is nothing, definitely not a tankless water heater. Navien has 6 residential models (CR-180, CR-210, CR-240, CR-180A, CR-210A, CR-240A) and then 3 commercial units (CC-180, CC-210, CC-240). These tankless water heaters are all relatively similarly...
