May be an answer, though it looks like you don't get any water until its hot ??????

OK, that's a slightly different take on a couple of others I have checked out. Looks like it just returns the cool water directly back to the cold line and because the hot line is open, it flows back to the hot water tank. I suppose if someone has a cold tap open elsewhere in the house between the unit and the hot water tank, there's a chance they might get luke warm water instead of cold. The other difference is that it uses power, whereas the other two I've seen are mechanical. Still, worth checking out. Thanks for the link.
