<div class="moz-cite-prefix"> Looks like a technically nice
approach - a solar heat collector using some (un-named) fluid with
a low freezing point so freeze-up isn't a problem, operable either
on straight solar heat gain or if insolation isn't enough to
attain desired temperatures then kick in a compressor and operate
as a heat-pump from the panel to storage.<br>
I wish they'd say that in so many words. The brochure wording
has a shady character similar to many pseudo-science marketing
scams. Yes, Nicolas Carnot. Heat pumps all, & most
refrigerators, use the cycle named after him.<br>
I'd ask for more specifications & performance test numbers
and references.<br>
