Thanks for readings! I'm new at this, which do you think is better?

Side note: We have to get a propane unit first then when we can open the street in 2 years convert to NG. The NG conversion kit on the Rinnai is $400. The conversion kit on the Noritz is $170 which is more normal.

That being said, the Noritz seems to have a much better flow rate than the Rinnai, however the Riannai is a little more efficent. I'm leaning to the Nortiz.

Do you guys have any thoughts?
