Very strong concentrations of chlorine can corrode the core of the heater. That said, they have to be VERY strong concentrations, for a prolonged time. If you are following mfg's instructions on how to sanitize, you will never be even close. My Jayco manual recommends 1/4 cup for every 15 gallons, letting it sit in all plumbing (including hot water system) for 4 hrs. They do advise to premix each 1/4 cup with a gallon of water - presumably to reduce initial concentration just in case a slug of full strength should end up where it shouldn't.
Now on my swimming pool, I have to be much more careful - the concentrations are much, much higher, and I have to make sure that it goes in after the heater, so it gets diluted in the pool before making its way back....
I've dumped both pool water and my trailer sanitized water directly on my lawn, with no ill effects, ever.
BTW - the Jayco manual also notes a faster method with double the bleach. I did it once. While fast (1 hr) it took a LOT of flushing to get rid of the smell. And it doesn't help that your nose gets used to it, so you think it's fine, until you get that big glass of water from the kitchen a couple of days later....
