Perhaps I'm missing something but they talk about using wasted
heat to generate electricity. But the best condensing boilers
are already running at 91% efficiency, so there's not much to
reclaim, certainly not 25% ????

It may be a very good way to heat your house _whilst_ generating
electricty (because you need to).
I doubt it is a better way of to heat your house than a condensing
boiler with correct installation and controls.

25% more efficient overall in energy. Modulates and must be better. You
don't "need" to generate electricity. You actually sell the surplus back to
the utility company.
