the basic concept of using the waste heat from solar panels to head domestic hot water is certainly not a new idea. I have heard of this idea years ago. But, if I am reading the link correctly, what they seem to be saying is that they have found a design that can be significantly more cost effectively installed while still making good use of most of the waste heat energy. I hope I got that right.
