thanks for the link
the other day i was reading about heat pump water heaters because they're listed on the
energy star stimulus package tax credit site in the non-solar water heater category. I looked online and couldn't find them anywhere here in the U.S.
But... on
this energy star site that describes them, they say "New models due out later in 2009 will utilize super-efficient technology to cut electric water heating costs by more than half! If you have time to plan ahead, consider this exciting new technology for your next water heater purchase."
... so basically I think these things are about to hit mass market (home depot / lowes) later in 2009 in America... which should drive the costs down way below $3500.
Let's keep our fingers crossed... :-)
