Where exactly did you get this graphic from? I really don't find anything good/right about it. You probably also need to distinguish much more what kind of air-to-air heat pump is being used.
but let's quickly go through: 1. Heating is more efficient with air-to-water heat pumps with the appropriate hydraulics. 2. Dehumidifying is both an advantage and disadvantage depending on whether you want it. You can't turn it off anyway. 3 and 4. Where is the difference for the customer between investment costs and installation costs? And having an indoor unit in every room is supposed to be cheaper than a few pipes in the screed? 5. Operating costs should be higher with air-to-air heat pumps due to disinfection of the indoor units 6. Air filter function? What does that have to do with heating? 7. Since when can an air-to-air heat pump produce hot water? 8. Space requirements. All those air-to-air heat pump indoor units don't require space? 9. Yeah okay 10. Funding eligibility changes constantly. What is the current situation anyway? 11. Comfort: Now it gets really bizarre. Here it is urgently necessary to distinguish between heating and cooling. And comfort in LL green? Despite drafts, noise, and so on?
