The 3 primary Navien models

NR-180

NR-210

These three are Natural gas systems, but you should note that they come in propane versions as well.  In fact as propane burns hotter than natural gas the propane versions are a bit more efficient.

Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing a longer life-expectancy and more resistance to erosion than copper heat exchangers. All tankless systems are designed to be cleaned and de-scaled, improving life span and durability.
