I need another water heater. Is a bigger one more efficient than a smaller one?

Absolutely!  Most conventional residential water heaters use electric resistance heating, which uses a large amount of electricity.  Using a much bigger heater will reduce your monthly energy costs, since it will consume less electricity.  This can be an enormous savings, in the range of thousands of dollars per year.
