Hi Everyone,

I have been thinking ahead about replacing my Navien CR-A 240, which has been running relatively well for the past 8 years. I assume that at a certain point, the repair bills will make this a reality. My unit has the two vents at the top, water into/out of the bottom and gas on the right.

Two questions:

1) If I get another Navien, will it likely be a simple install given that everything should be already roughly piped in? Just a quick swap? Would be great if this helps save on labor costs. What about other brands? Do they have a similar configuration? BTW, I'm not considering DIY.

2) What are the good units/brands these days? My understanding was that the early Naviens were problematic but have improved.

Thanks!

over the life of any tankless system
you can expect to replace almost all the
complementary functioning parts at least once...
hopefully bugs are worked out with upgrades
those parts are not that costly when averaged over life of unit

You heat exchanger should still be under warranty (15 yrs)
& life expectancy on exchanger should be 20-25 years...

& 1 of the beauty's of tankless is quick change outs when needed
if staying with same brand/style/model

Peace
