Hi all, My wife has decided that we should get a tankless hot water heater to save energy. They are fairly uncommon in the USA, but fairly common in the rest of the world. Does anyone on the list have any experiences they could share with me? We are looking at the Navien CR-180A (this one includes a small, 1 gallon holding tank as a buffer) and the Noritz NR83-DVC. Any personal experience with either of these? Also, the Noritz is a new model. If you have experi= ence with an older model that would also be helpful. Thanks! Bill --=20 Psst...=A0 Hey, you...
