Folks on this forum are very polarized on tank vs tankless. You should read the threads under that topic before you decide. In general, tankless are much more costly, require frequent service and qualified service people are sometimes hard to find. They are limited in the amount of hot water they can deliver especially in cold winter climates, and generally cost as much or more over a long period of time. They usually require a larger gas supply line that are usually found in home. I have no opinion about the hybrid heaters, but gas is far less costly to operate than electric and recover faster. To me, there is no question, but you have to decide for yourself. Just remember that the opinions you get are very bias, pro or con.
