The only concession I'll make to tankless electric is if they are
paired (mandated by code) with a reputable (A fine product is
presented here: http://tinyurl.com/2dgem6). At $10,800 per kilowatt
for new nukes, it would be cheaper to install a

1.5 kilowatt elements (or less. Check out the Ecopeak with 800 watt
lower element) in every home. That would be leveraging our existing
infrastructure, retiring old nukes and give us a longer lead time to
integrate new sustainable technologies.
