i feel like if anything seriously goes wrong with these heater, it would probably be time to get a new one instead of trying to repair them...

Guy I worked with (a plumber) bought a Takagi tankless heater and was so horrified by all the circuit boards, etc that he immediately bought another one just to have parts on hand. This was 12 years ago or so, but at the time was about $1200 apiece. Better be saving a LOT of money on gas at that point.
