These are pretty old, but I've got a tankless water heater in my house and just love it. These point-of-use heaters are even cooler because you don't need a massive room in your basement for a fat heater and tank combo and the water heats instantly and is never ending, in theory.

Tankless heaters haven't taken off in the States, for some reason, but advancements like smaller, more efficient heating systems and solar panels and all that hippie junk might turn the tide in the next few years. Or maybe Hummer will come out with the Hummer Hot Water Heater—0% efficient, 100% badass.
