I read a study looking at the difference between tankless and tank water heaters. Summary the more hot water you use the smaller the win is for tankless. Other thing I've read and seems true is gas and heat pump water heaters cost about the same to run. I installed a heat pump unit five years ago. Works okay for two people. If you had three teenage girls and a wife that likes baths a tankless would be a better choice.
