Sounds like you are already not doing too badly.
Try posting your house with the heating load calculation(s) in the pink htd forum, you’ll get more expert information there.
Not assessable without plans, but the heating load is very high, especially since planning includes a ventilation system. The heating load often contains too many safety margins (search for crinks Tool). Depending on the architecture, BKA might make sense to further lower the supply temperature.
Personally, I would try to avoid buying an expensive air-to-water heat pump from the heating engineer (they don’t last forever, you buy it twice like any heating system) and rather take another look at/check the house concept and reduce the heating load or plan with a trench collector, especially if you live in a colder region I would consider air as a source not optimal.
