Those prices... out of this world? Can you explain to me how it is possible to get a 7kW air/air heat pump installed for a total cost of ~17.000 [1] Swedish kronor (~$1600 at current rate) for a fraction of the price of these things? These devices all come with networked remote control, most of them can be integrated into 'home automation' systems without problems, they tend to work down to around -30°C (-21°F) albeit with lower efficiency (as will these devices). All that is 'missing' is the 'air quality' claim - although several of these heat pump manufacturers make claims about their devices filtering the air, using ionizers to 'increase air quality' and such. What remains is the Apple/Nest-like design and the claim of better integration with thermostats. To me this does not explain the factor 10 price difference, especially given that the Swedish prices include the high Swedish value added tax (25%) as well as the installation costs. What am I missing?
