To be honest I suspect the tech has been available here too, but the marketing is just confusing. But again, "cooling your house to survive summer" is, for real, a pretty recent concern to have in Europe, as opposed to "heating and insulating your house to survive winter".
It's almost as if the climate is warming in accordance to what physicist have been saying for 30 years.
"Qui aurait pu prévoir ?", as the other one would have said (sorry for the franco-french reference. And I know we'll "regret" the guy next year...)
