New style heaters have Titanium elements and a slightly different body. The old ones have been superseded by this new Retrofit. Note that the less-common 4-6kW heaters are still the older style.
Older style heaters are more susceptible to poor water chemistry due to their Teflon coating. Bromine and other Sanitizers that induce low pH are the cause of this. Obvious signs of damage due to water chemistry is not covered by warranty. See example of non-warranty damage.
