Dang Tony, as I saw the posts going up with the pics I was starting to think someone held out on us and discovered some pics somehow left on a phone after a trip to Vermont :-)
You know, it is not that they cannot do it, or even save people money overall. It is just that there have been some fairly unreal expectations.
I figure if they bring this to market and it is well done, good construction, good service life, they have a shot at making electric tankless more of a reality (read the reviews of the existing products - they appear to suck!) And there are likely a number of commercial nitch markets. But people should not expect more than is possible.
Cheers (you really had me hoping with those pics at first :-) how's the leg? )
