I love my Navian tankless, can have 2 showers and be filling the bathtub at the same time. No issues but I'm only on year 2 now.
So is there no possible way to get a replacement mid efficiently heat exchanger?

Buy used. Stock ran out on them 20 years ago.This quote is hidden because you are ignoring this member. Show Quote
You can, but nobody stocks it so it's a long wait, and it costs almost as much as a new high efficiency furnace. It's quite the racket.This quote is hidden because you are ignoring this member. Show Quote

Depends on the model. For my Carrier, to get a heat exchanger cell is $150-330 USD. My furnace takes four cells, so I'd be creeping up near the price of a new furnace.This quote is hidden because you are ignoring this member. Show Quote
Some models have cells that cost $50, others you can't buy for love or money. It's a bit of a crap shoot.
But you'd be set for another 30+ years, unlike a high efficiency.This quote is hidden because you are ignoring this member. Show Quote

And I assure you that's the primary reason I'm looking at doing the exchangers and upgrading to an ECM motor. Keep this thing ticking as long as possible.This quote is hidden because you are ignoring this member. Show Quote
Will the control board last that long, and will you be able to find a replacement? Those boards are like high school electronics class etched boards, so troubleshooting shouldn't be too bad. But that's another dice roll there. What if that unlabelled IC goes bad? That was my question peeking at the guts of my furnace before I said fuck it and went new furnace. The yearly issues with the new unit is fucking annoying tho so there's a bit of regret not taking a chance!This quote is hidden because you are ignoring this member. Show Quote

Yeah, that's the question isn't it? Could spend a bunch making it like new only to have the electronics shit the bed. Ugh.

The defrost method is reverse cycle.
Interestingly a Samsung I installed a year ago that's rated down to -25c was doing pretty good at -30 the other day. The customer thought it wasn't working, but they weren't giving it enough time to preheat the indoor coil before the fan would operate. Because it had no fan after 30 seconds they thought it was dead, but the mini splits likes to avoid blowing cold drafty air so it it takes a bit for the fan to come on.
Some of the high efficiency brands have 20 year heat exchanger but they get into pretty ratty condition quickly when the condensate leaks through the furnace for a short amount of time because it's so acidic. Some of these stepper motor gas valves off warranty are just silly in price, sometimes a double hit when they have upgraded the gas valve and it requires a new board with it.

Here's an easy test. Maybe not conclusive, but a fairly good indicator:This quote is hidden because you are ignoring this member. Show Quote

I’ve worked on a few WaterFurnace ground source heat pumps in the past that will operate at any temperature, provided the fish pond is deep enough to not freeze solid in the winter. I hated them 20 years ago, but their complexity is a lot more palatable these days and it’s likely they’ve made vast improvements since then.
I thought the key indicator of a cracked HX was dying of CO poisoning.
More of a lagging indicator, I suppose...
Good tip, thanks! I've already checked for flame rollout and didn't notice anything obvious but the match test should be more sensitive.This quote is hidden because you are ignoring this member. Show Quote
Realistically, that's more or less a myth. Think about the candle test linked above - it works because when the blower is running, it blows air into the exchanger, not the other way around. And when the burners are running, so is the venter motor - which puts the exchanger under negative pressure to draw the flame in from the burner and the exhaust gases out the flue. There's really not many realistic ways to get combustion products out of the exchanger and into the air stream.This quote is hidden because you are ignoring this member. Show Quote

I hadn't clicked the candle link test but I figured there must be more safety involved.
