Navien Model 240A
We are building a new house and our builder has suggested this tankless model for heating water for the whole house. The house has 3.5 baths and the plumbing is somewhat spread out. I told him that I wanted instant hot water and he said that this model can provide that. I've seen some bad reviews but many seem to be for the CR model. I believe ours will be the NR model. Would love some opinions on what you think of it....thanks!
