So much for "everything is running perfectly" :cool: These are more like "small" problems (my boss calls them challenges, there are no problems).
1. Installation of surface collectors. The first plan stated that the collectors would be 5 meters wide and about 20 meters long, thus occupying less than 1/4 of the area of the backyard. Now the company has changed because the previous one, which worked nationwide in Germany, no longer works in the east, as the earnings there are lower. Therefore, a regional company has to be used. However, this company installs the surface collectors not stacked (80cm depth), but side by side and at a depth of 1.30m. This is positive because they are then even more effective, but it takes up 8.5m of the 20m width of the backyard. We are not allowed to plant deep-rooted plants over that area, build any sheds (only easily movable garden sheds), and the pool (if we wanted to have one) is not allowed to be built there either. We now find that not so bad, only that I just found out about it yesterday before the work started. According to the general contractor, there was a plan from the managing director that provided for a width of 5m. The worker ("Praktiker") buried the plan yesterday and said that it is not feasible like that...
2. Delivery date for the geothermal heat pump is still unknown. We hope that it will be delivered by the end of August. Hope dies last...
