[Greenbuilding] [BULK] Re: Tankless HW and hard water

[Keith Winston]

Do you really mean the tanks in your area fail due to scale formation, 
or to simple deposits of sludge etc. in the tank? Also, the element gets 
MUCH hotter than 120, as does the water in it's immediate vicinity. And 
of course corrosion is yet another issue.

You're a goofball. That's a compliment.
