We recently moved from CA to TX and I want to replace our new home's tank heaters with tankless (gas). In CA, we had Takagi since the early 2000s, so that's all I know. One plumber recommended Rinnai over Takagi, and another came in with a quote for Navien ... and when I asked how much for Rinnai or Takagi he said $2000 more (!!). When I search for tankless heaters without installation, they are below $2000 so I don't know why the difference would be so much (probably won't go with that plumber) but I'm wondering if anyone has any strong feelings or experience one way or another? We have a large house so we need something with a lot of BTUs - I think the max is 199k?
