    Where do you live?

    Is it an area where copper has longevity problems?

    How far are the bathrooms from the water heater?

    There are people that love their tankless systems. Personally, where I live, I think they are just not a great solution. The winters in NJ are likely to be marginal for the use of a tankless...incoming watre will be fairly cold. Sizing one for multiple fixture use requires a very significant fuel supply, and upfront cost. I don't think you'd ever recover the upfront costs verses any fuel savings (which may not be huge depending on the system chosen. Personally, standby losses aren't as large as some would make you think they are in most cases.

    Pex would be easier to install. If done properly, it should work as well as copper...each has it's pros and cons.

    Use the search function...lots of discussions on pex verses copper.
