True tankless heaters are supposed to last longer, also lets not split hairs here, electric vs gas is pretty big on how long they last, that said my current water heater which was rated at 6 years (I know because I definitely would have scoffed at a paying an extra hundred bucks or so for "3 more years") is currently on year 15 or so (I forget when I installed it), but other than replacing the thermocouple or burner assembly ($12-30 fix) it's given me a lot of life, and before that I think the water heater had to be 20+ years old. Not sure I could say the same with a tankless one as far as repairs go for something minor.I’ve given this some thought since I installed a tankless water heater on our house. I did not watch the video so I don’t know if he did something different from what I had planned but one of the biggest reasons I didn’t move forward was because most, if not all, the plumbing inside is copper.
@sfsuphysics, you talk about the unit failing. Tankless water heaters are known to last 2-3 times longer than most regular tank water heaters. Plus there’s no maintenance with them (your supposed to drain the tank on your water heater like every year, but I don’t know anyone that actually does that).
Allows it to retain shape and not expand or turn to mush with higher temperatures.aluminum pex?
True. But you have to do it right, and the odds of getting a conversion kit for that specific model is low.I thought most LP/NG conversions were done by replacing the nozzle that squirts the gas into the combustion chamber.
